NATURE AND STAGE OF PROCEEDINGS This is a patent infringement litigation initiated by LML Patent Corporation
(" LML" ) against defendants TeleCheck Services, Inc. (" TeleCheck" ), Electronic Clearing House, Inc. (" ECHO" ), XpressChex, Inc. (" XpressChex" ) and Nova Information Systems, Inc (" Nova" ) (collectively, " Defendants" ). Fact and expert discovery has concluded, and the parties have conferred regarding claim construction. As discussed below, the parties have asked the Court to construe a number of terms and phrases contained in the asserted claims of the patent-in-suit, U.S. Patent No. 5,484,988 (" the `988 patent" ). Defendants collectively submit this opening brief regarding the construction of disputed terms and phrases set forth in the chart entitled Proposed Constructions of Disputed Claim Terms in the co-filed Joint Proposed Claim Construction Statement (Ex. A). II. SUMMARY OF ARGUMENT The `988 patent is a narrow patent relating to a specific system and method for conducting electronic check transactions at a retail check-out counter, or " point of sale." The `988 patent' s inventors, Robert Hills and Henry Nichols, were not the first to invent " electronic check conversion" at the point of sale. As set forth in the prior art and confirmed by LML' s own expert, other forms of electronic check conversion at the point of sale were known in advance of the purported invention of the `988 patent. As originally filed, the `988 patent claims sought a broad scope of protection, but the claims were successively amended to narrow and then further narrow their scope. The result are patent claims that require, among other limitations: · · conducting electronic transactions and transferring funds using bank account information from " any bank check;" conducting transactions " without using the check as a negotiable instrument," so that, as properly construed, " the check, at no time, takes on the status of a negotiable instrument;"

·
reading only " consumer bank account information" from a check, rather than also reading the check serial number, so that the same check can be used over and over again; and " verifying that account numbers were accurately read at the point of sale" by visually confirming the account numbers on the check against a display screen.

A broader construction like that proposed now by LML renders many of the claims, including all independent claims, anticipated by the prior art. (Id.) LML' s attempt to now assert a contrary construction for purposes of litigation should be rejected. All of Defendants' constructions are fully supported by the patent claims, specification, prosecution history, and prior art cited during prosecution. They are fully consistent with the understanding of one of ordinary skill in the art at the time of the invention. This last point is significant because of LML' s apparent reliance on " evidence" created many years after the filing of the patent-in-suit. For example, LML

and its expert rely on guidelines relating to Point-of-Purchase (" POP" ) transactions issued by the National Automated Clearinghouse Association (" NACHA" ). These rules were adopted long after the date of invention of the `988 patent, and are improper evidence for purposes of claim construction. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005). LML' s attempt to rely on such evidence should be rejected. In short, each claim construction proposed by Defendants is consistent with the understanding of one of ordinary skill in the art at the time of the invention, based on the intrinsic record of the `988 patent. In contrast, LML ignores the intrinsic record, and proposes overly-broad definitions crafted to support its litigation positions.

FACTUAL BACKGROUND A. The `988 Patent
The `988 patent issued January 16, 1996 from an application filed June 9, 1994. (Ex. X.) LML asserts priority back to the original application, filed November 13, 1992. (Id.) The `988 patent generally describes a system and method for converting paper checks to electronic transactions at the point of sale, using the check " as the basic source of identification of the individual and of the individual' s bank and whereby the bank account is debited." (Id. at 1:13-15.)2 The `988 patent claims were not allowed until after the claims were narrowed to recite conducting transactions " without using the check as a negotiable instrument" (or equivalent language), and further narrowed to recite the capability to transfer funds using account information " from any bank check."

B.
The `988 Patent's Electronic Check Processing System and Method
The `988 patent' s system and method for electronically converting paper checks presented at the point of sale begins when a customer making a purchase initiates a transaction by providing the merchant any bank check. According to the patent specification, the check presented by the customer is preferably a " specimen" or " blank" check. (Id. at 7:48.) The merchant obtains certain account information from the consumer' s check. Many, but not all, bank checks bear Magnetic Ink Character Recognition (" MICR" ) numbers across the bottom of the check. (Id. at 6:66; 7:64-65.) This MICR information includes the " ABA/Transit" and routing number of the check writer' s bank, as well as the check writer' s account number. (Id. at 10:29-31.) The MICR line may also include the check number, although in the `988 patent system this information can be " dropped" before proceeding with the electronic transaction. (Id. at 10:31-34.) The `988 patent specification describes that MICR information may be entered into a point of sale terminal manually via a keypad, or may be entered by reading the check with a check reader. (Id. at 7:57-62.) The patent describes magnetic " MICR" readers and optical " OCR" readers as equipment that may be used to read the information from the check. (Id. at 5:44-49.) Once the account information is entered, the merchant verifies that the information was read properly by visually checking the terminal' s display panel, and then enters the amount of sale to initiate a check " verification" process. (Id. at 7:63-8:22.) Check verification was a well known process many years before the `988 patent. It involves accessing one or more databases to determine whether a check presented at the point of sale is likely to clear. (Id. at 7:19-31.) The `988 patent describes the use of thenexisting verification databases such the SCAN® database. (Id. at 7:31-34.) If the verification is approved, the merchant returns the check to the customer at the point of sale and the terminal prints an authorization receipt for the customer' s 4

Page 12 of 46
signature. (Id. at 8:23-29.) At the time the `988 patent was filed, and still today, an express written authorization is required for any electronic debit of a consumer' s bank account. The transaction is later electronically processed for payment through an automated clearinghouse or an " ACH" network. (Id. at 8:30-42.) C. Prior Art Point of Sale Electronic Check Processing Systems
Long before the effective priority date of the `988 patent, various methods of electronic check conversion at the point of sale were well known in the prior art. Systems and methods enabling the electronic processing of paper checks presented at the point of sale have been discussed in the payments industry, disclosed in prior art patents, and implemented by payment processing corporations since the early 1980' s. For example, U.S. Patent No. 5,053,607 to Carlson (" the `607 patent" ), U.S. Patent No. 4,321,672 to Braun et al., U.S. Patent No. 5,175,682 to Higashiyama et al. (" the `682 patent" ), and commercial payment processing systems described and/or offered by a number of entities described electronic check processing systems having many or all of the features of the `988 patent. These systems each included a terminal and a MICR reader for automatically reading the ABA/transit routing number and bank account number from checks presented at the point of sale, communication with databases for check verification, and communication with an automated clearing house for electronic debiting of the consumer' s account based on the information obtained from the check. The `607 patent, for instance, discloses a point of sale device adapted for electronic check processing and funds transfer and a system for performing check authorization and electronic funds transfer at the point of sale. (Ex. S at 2:24-28; 15:3842; 22:32-25:10.) The described system includes a point of sale terminal capable of reading information from any bank check containing a MICR line. (Id. at 3:47-48; 6:3841, 49-57; 25:27-28.) The terminal has a MICR reader (id. at 8:1-3; 11:40-43), alphanumeric keypad (id. at 13:39-40), merchant and customer display screens (id. at 5
Case 1:04-cv-00858-SLR
Document 290
Filed 10/14/2005
Page 13 of 46
9:18-31), a printer (id. at 4:50-52), and memory for storing information within the terminal (id. at 4:44-46; 19:12-17). To initiate a transaction according to the `607 patent, the merchant inserts the check into the terminal, enters the amount of the transaction using the alphanumeric keypad and requests check verification. (Id. at 22:57-23:22; 23:60-24:36.) The terminal reads the MICR information from any check, even one that is folded, wrinkled, or has a torn or partially damaged MICR line. (Id. at 6:38-52.) The system initiates a verification process to confirm that sufficient funds exist in the customer' s account (id. at 24:24-36), and if approved the terminal communicates with a computer " to perform an electronic funds transfer" (id. at 4:40-41). The printer prints authorization information on the check. (Id. at 24:45-60, 10:13-53.) If insufficient funds exist, the transaction is terminated. (Id. at 17:24-31.) At the end of a transaction, the " cancelled check would be presented to the customer as part of his receipt." (Id. at 18:52-60; 25:4-10.) The `682 patent to Higashiyama discloses another system and method for electronically processing checks presented at the point of sale, in a manner that treats a check as the " equivalent of an electronic debit card." (Ex. T at 2:43-50; 3:11-16; 6:1012; 10:27-30.) The' 682 patented system includes one or more point of sale terminals (id. at 3:13-16), each of which includes a MICR reader for reading information from the consumer' s check (id. at 3:16-19; 10:24-26), a printer for " printing a sales slip, printing validation information on a check, or printing a check receipt" (id. at 3:25-28), and a keypad (id. at 3:66). The `682 central computer is connected to a telecommunications unit capable of data communications with automated clearinghouses, financial institutions and verification services. (Id. at 7:55-8:2; see also 3:33-36.) When a transaction is initiated using the system described by the `682 patent, the MICR reader receives customer account information directly from any check presented at the point of sale. (Id. at 3:45-50.) The account number is verified against authorization files maintained by an external verification service. (Id. at 4:14-22.) If a transaction is 6

Document 290
Filed 10/14/2005
Page 14 of 46
authorized, validation and cancellation information is printed on the check. (Id. at 4:2643; 8:55-59.) The merchant then returns the check to the customer at the point of sale. (Id. at 4:54-57; 7:16-20, 35-36; 8:60-62.) If the merchant desires, a separate receipt may be printed and given to the customer stating that payment was made by check and the check is being electronically processed. (Id. at 4:61-68; 9:4-6). The electronic data is then batch transmitted for processing, for example, through an automated clearing house. (Id. at 5:1-7, 10-13, 18-20, 28-31, 37-46; 9:12-15.) These and other prior art references confirm that any purported novelty in the `988 patent claims may only be maintained (if at all) through a narrow construction involving the specific embodiments set forth in the patent specification. Indeed, during prosecution of the `988 patent, the `607 patent and other references were distinguished on specific grounds related to limitations added to the claims by amendment. D. Prosecution History of the `988 Patent 1. The 1992 Application
The original application leading to the ' 988 patent, Serial No. 07/975,717, was filed on November 13, 1992. (Ex. B.) Nine claims were included in that application, two of which were independent (claims 1 and 9). The original independent claims recited point-of sale electronic payment processing systems and methods designed to receive consumer bank account information from either debit-type cards or checks, transmit that information to a central computer, perform a verification process, and transfer funds through an automated clearing house network. (Ex. B at LML-EP-000104-06.) In an initial Office Action dated September 23, 1993, the Examiner rejected claims 1-9 under 35 U.S.C. § 102(b) as anticipated by U.S. Patent No. 4,270,042 to Deming or U.S. Patent No. 4,823,264 to Case. (Ex. C.) In response, among other changes, the Applicants deleted language from claim 9 relating to the card-based embodiment, and added a new claim 10 directed to the same embodiment. (Ex. D at

Case 1:04-cv-00858-SLR
Document 290
Filed 10/14/2005
Page 15 of 46
LML-EP-000151-55.) Applicants also argued that their claims were not anticipated by Case or Deming. (Id. at LML-EP-000156-59.) In a Final Office Action dated March 9, 1994, the examiner again rejected Applicants' amended claims as unpatentable under 35 U.S.C. § 103 over Case and Deming, as well as U.S. Patent Nos. 5,053,607 and 4,678,896 to Carlson and U.S. Patent No. 4,672,377 to Murphy et al. (Ex. E.) 2. The 1994 Application
Applicants filed a continuation application and a Preliminary Amendment on June 8, 1994. (Exs. F, G.) The 1994 Preliminary Amendment contained additional disclosure relating to the use of a check as a negotiable instrument. The new disclosure included text characterizing Case and Deming as systems in which checks are treated as negotiable instruments, and further stated that none of the prior art " completely does away with the need and use for a negotiable draft instrument while using the consumer' s bank check for identification and verification only." (Ex. G at LML-EP-000172.) The new disclosure also stated that a " further object of the present invention is to significantly reduce the use of checks as negotiable instruments in effecting the purchases of goods or services." (Id. (underlining identifying amended language).) The 1994 Preliminary Amendment also included narrowing amendments to the claims. Claim 1 was amended to recite that transactions take place " without using a bank check as a negotiable instrument." (Id. at LML-EP 000172-73.) Claim 9 (which would eventually issue as claim 8) was amended to recite reading MICR information on the check " for the sole purpose of obtaining consumer bank account information." (Id. at LML-EP 000173-74.) The Preliminary Amendment further added 12 new claims, including independent claim 11 (which would eventually issue as claim 9). (Id. at LML-EP 000175-78.) Independent claim 11 also recited the limitations " for the sole purpose of eliciting
8

Page 16 of 46
consumer bank account information" and transferring funds " without using a bank check as a negotiable instrument." (Id. at LML-EP 000175-76.) Following this submission, the Examiner again rejected all pending claims as indefinite in an Office Action dated October 28, 1994, concluding among other things that claim 1 did not capture the argued novelty in the specification. (Ex. H. at LML-EP 000181.) The Examiner also stated that use of the check " solely" for access would be a trivial modification from the prior art. (Id. at LML-EP 000181.) Applicants filed another Response to Office Action on January 30, 1995, further narrowing the claims to recite processing transactions not from " a" single bank check, but rather from " any" bank check. Specifically, the Applicants amended claim 1 to recite a point of sale terminal adapted to receive information from " any bank check," amended claim 9 to recite presenting " any bank check" at the point of sale, and amended claim 11 to recite means for reading information from " any consumer bank check." (Ex. I at LML-EP-000183-85.) Claim 9 was further amended to include the limitation " without using the check as a negotiable instrument," conforming to the similar limitations previously added to claims 1 and 11. (Id. at LML-EP-000184.) To overcome the Examiner' s rejections, Applicants repeatedly argued that the prior art did " not disclose the use of any bank check solely to derive consumer information and not for use as a negotiable instrument, as recited in independent claims 1, 9 and 11." (Id. at LML-EP-000190, 207; see also LML-EP-000192-206.) After persuading the examiner that no election between claims was necessary, the `988 patent issued on January 16, 1996. At issuance, what was claim 9 during prosecution issued as claim 8, and former claim 11 issued as claim 9.3
3
In the remainder of this brief, for clarity and convenience Defendants refer to claims 8 and 9 of the `988 patent by these issued claim numbers, recognizing that issued claim 8 was prosecuted as " claim 9," and issued claim 9 was prosecuted as " claim 11." 9

IV.
DISCUSSION A. Legal Standards of Claim Construction
The goal of claim construction, repeatedly affirmed by the Federal Circuit, is to determine the meaning of claim terms within their appropriate technical context and time frame. See, e.g., Nazomi Commc'ns. v. Arm Holdings, PLC, 403 F.3d 1364, 1368 (Fed. Cir. 2005); V-Formation, Inc. v. Benetton Group SpA, 401 F.3d 1307, 1310 (Fed. Cir. 2005).

415 F.3d at 1313; see also Nazomi Comms., 403 F.3d at 1368. Interpretation of disputed claim terms in their appropriate technical context requires the construction of terms as they would have been understood by one of ordinary skill in the art. See, e.g., Phillips, 415 F.3d at 1313; Metabolite Labs., Inc. v. Lab. Corp. of Am. Holdings, 370 F.3d 1354, 1361 (Fed. Cir. 2004). In construing disputed claim terms, intrinsic evidence should be considered first; and if ambiguity remains the court may resort to extrinsic evidence. See, e.g., Phillips, 415 F.3d at 1314; Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1116 (Fed. Cir. 2004). Claim terms are generally given their ordinary meaning unless the intrinsic evidence reveals a special definition different from the meaning one of ordinary skill in the art, at the time the application was filed, would understand it to have. See, e.g., Phillips, 415 F.3d at 1316; PC Connector Solutions LLC v. SmartDisk Corp., 406 F.3d 1359, 1363 (Fed. Cir. 2005). Claim language is read in the context of the entire patent, including language in other claims, both asserted and not. See, e.g., Phillips, 415 F.3d at 1313-14; Pause Techn., LLC v. TiVo Inc., 419 F.3d 1326, 1331 (Fed. Cir. 2005). Where terms appear repeatedly, those common terms should be assigned the same meaning. See, e.g., Innova, 381 F.3d at 1119. The patent' s prosecution history is also deemed part of the intrinsic evidence and is of " primary significance in understanding the claims." Markman v. Westview Instruments, Inc., 52 F.3d 967, 980 (Fed. Cir. 1995), aff'd, 517 U.S. 370 (1996); see also, e.g., Phillips, 415 F.3d at 1317. Narrowing amendments made during prosecution limit the subsequent scope of the claims and must be considered during claim construction. See, e.g., Pause Tech., 419 F.3d at 1331-32; Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722, 736 (2002).

Interpretation of Disputed Claim Terms Relating to "Any Bank Check" 1. Claims 1 & 8: "any bank check" means "any type of check drawn on a financial institution"
Independent claims 1 and 8 of the `988 patent both recite transactions involving " any bank check." (Ex. X at 11:37-38, 12:21-23.) Consistent with the intrinsic evidence and its plain and ordinary meaning, the term " any bank check" should be construed to mean " any type of check drawn on a financial institution." See, e.g., Phillips, 415 F.3d at 1316. That plain and ordinary meaning of " any bank check" includes, without limitation, personal or corporate checks drawn on U.S. bank accounts, personal or corporate checks drawn on foreign bank accounts, payroll checks, two-party checks, traveler' s checks, damaged checks, and checks in which the MICR line is not able to be read by an automated check reader. REDACTED a. The specification and claims support Defendants' proposed construction of " any bank check"
The `988 specification provides no explanation of the term " any bank check" to differentiate it from the plain and ordinary meaning it would be assigned by one of ordinary skill in the art at the time of the invention. The specification states, for example, that the patent is not limited in geographic boundary: " operational parameters of the present invention allow freedom from customary state or other geographically limiting criteria typical when accepting and processing `paper' checks." (Ex. X at 3:16-20.) The specification further describes processing business and corporate checks. (Id. at 3:45, 4:23 and 4:49-51.) The specification contains no special definition of " bank" excluding from its scope credit unions or other types of financial institutions that issue checks. For example, the specification states that the central computer communicates with a banking " institution" for purposes of debiting consumer accounts and crediting system subscriber 13

accounts. (Id. at 6:53-59; see also 7:40-43.) Likewise, the purported invention provides consumers " free and unrestricted access to funds secured in bank accounts of various types," including " consumers' checking account or bank depository reserves." (Id. at 3:51-56; 4:2-3.) b. The prosecution history indicates that " any bank check" means " any type of check drawn on a financial institution"
The `988 prosecution history also supports a construction of the term " any bank check" consistent with its plain and ordinary meaning. During prosecution, the claims were narrowed to recite the ability to process checks using " any bank check" in response to the Examiner' s pending rejection of all proposed claims. (Ex. I at LML-EP-000183.) In other words, the ability to process a single type of bank check was no longer sufficient to meet the claims. Instead, the system had to have the capability to process all types of checks, for example, personal checks, corporate checks, foreign checks, official checks, etc. In the accompanying Remarks, the Applicants described newly amended claim 1 as reciting a checkwriting point of sale system including a point of sale terminal that " accepts bank account information from any bank check." (Id. at LML-EP-000189.) Amended claim 8 was described as a " point of sale process comprising presenting any bank check to a merchant' s terminal. . . ." (Id.) Applicants characterized amended claim 9 as a " checkwriting point of sale system including a point of sale terminal which " accepts bank account information by reading the MICR information from any bank check." (Id.) In the same Response to Office Action, Applicants repeatedly distinguished the claimed invention over the prior art by stating that none of those references " disclose the use of any bank check solely to derive consumer information and not for use as a negotiable instrument." (Ex. I at LML-EP-000190, LML-EP-000207.) Because all the intrinsic evidence indicates that one of ordinary skill in the art at the time of the invention 14

Page 22 of 46
would have understood the term " any bank check" to have its plain and ordinary meaning, the Court should construe the phrase accordingly to mean " any type of check drawn on a financial institution." c. Extrinsic evidence confirms that one of ordinary skill in the art would construe " any bank check" to mean " any type of check drawn on a financial institution"
REDACTED
In addition, documents describing the purported invention distributed by the patent' s prior owner, ChequeMARK, confirm that Applicants defined " any bank check" 15
Case 1:04-cv-00858-SLR
Document 290
Filed 10/14/2005
Page 23 of 46
not as simply " a bank check," but as a bank check drawn on " literally any banking institution within the United States." (Ex. W at ECHO 00002741.) In that summary , ChequeMARK explained that " (p)rocessing beyond the geographic boundaries of the United States is further contemplated as similar agencies, regulatory bodies, and interbanking mechanics exist in foreign countries capable of facilitating the means of electronic monetary transfers from preauthorized banking accounts." (Id.) Both the intrinsic and extrinsic evidence supports an interpretation of the term " any bank check" to mean " any type of check drawn on a financial institution." 2. Claim 9: " any consumer bank check" means " any bank check drawn against a consumer bank account"
Independent claim 9 recites a " checkwriting point of sale system" including a terminal " comprising reading means for reading magnetic ink character recognition numbers on any consumer bank check . . . ." (Ex. X at 12:42, 53-56.) One of ordinary skill in the art would interpret this portion of claim 9 to mean " any type of check drawn on a financial institution," with the added limitation that the check be " drawn against a consumer bank account," as is consistent with the plain and ordinary meaning of the phrase. This construction is consistent with the specification, as set forth above with respect to the " any bank check" limitation. Defendants' construction is further supported by the prosecution history. As with the " any bank check" limitations, claim 9 was narrowed during prosecution to recite " any" consumer bank check. (Ex. I at LML-EP-000185.) Applicants also argued during prosecution that their " invention can read in account and other information directly from the consumer' s ordinary bank check." (Ex. C at LML-EP-000158-59.) Consistent with its ordinary meaning, the phrase " any consumer bank check" should be interpreted to mean " any bank check drawn against a consumer bank account."

Claims 1, 8 & 9: " any" means " one or some indiscriminately of whatever kind"
Claims 1, 8 and 9 of the `988 patent all preface their description of a bank check with the adjective " any." (Ex. X at 11:38, 12:22, 55.) In the parties' Joint Proposed Claim Construction Chart, LML states that the term " any" is a " plain English term" that " needs no construction." (Ex. A.) LML is incorrect, because the prosecution history requires that a broad dictionary reading of " any" is improper. In this case, the prosecution history indicates that Applicants surrendered the broad " plain English" definition of the word " any" that LML seeks now to adopt for purposes of this litigation. While resort to a dictionary may be proper, only a definition consistent with the prosecution history of the `988 patent should be adopted. Merriam-Webster' s dictionary defines the term " any" as " one or some indiscriminately of whatever kind." (See http://www.m-w.com/cgibin/dictionary?book= Dictionary&va=any.) This dictionary definition is consistent with the prosecution history, in which the patent claims were amended to recite the ability to process " any" bank check, rather than a single type of bank check. In particular, the Applicants surrendered during prosecution any broad dictionary definition of the word " any" that would mean simply " a." See, e.g., Merck & Co. v. Mylan Pharm., Inc., 190 F.3d 1335, 1340-41 (Fed. Cir. 1999). In a January 30, 1995 Response to Office Action (Ex. I), Applicants amended claims 1, 8 and 9 to include the word " any" in that Response, expressly replacing the word " a" in claim 8 (designated claim 9 at the time). In the Remarks, Applicants sought to distinguish the prior art by arguing that " Case does not disclose the use of any bank check . . . ." (Id. at LML-EP000190.) It was not until the term " any" was added to independent claims 1, 8 and 9 that the `988 patent was allowed to issue. The doctrine of claim construction also requires that the definition of " any" be restricted from meaning " a." Claims 2 recites " a consumer check" (Ex. X at 11:60), 17
Case 1:04-cv-00858-SLR
Document 290
Filed 10/14/2005
Page 25 of 46
while claim 9 recites " any consumer bank check" (id. at 12:66). There is no dispute that " check and " bank check" should be read similarly, and so the only distinction between these two terms are the words " any" and " a." The doctrine of claim differentiation dictates that these separate words be given separate and distinct constructions, so as not to render any claim term unnecessary or superfluous. See, e.g., Innova, 381 F.3d at 1119. 4. Claims 1, 8 & 9: " subsequently transmitting the transaction event information to a bank for subsequent automated clearing house operations" and " enabling automated clearing house communication for transferring funds" mean " electronically communicating with an automated clearing house for transferring funds electronically based upon the consumer bank account information obtained from any bank check presented at the point of sale
Claim 8 recites a checkwriting point of sale process including the step of " subsequently transmitting the transaction event information to a bank for subsequent automated clearing house operations." (Ex. X at 12:21, 39-41.) Claims 1 and 9 similarly recite a point of sale checkwriting system " enabling automated clearing house communication for transferring funds." (Id. at 11:36, 50-55; 12:42, 60-66.) In accordance with the overall context of the claims, the language of the specification and their plain and ordinary meaning, these phrases should be construed to mean " electronically communicating with an automated clearing house for transferring funds electronically based upon the consumer bank account information obtained from any bank check presented at the point of sale." Since claims 1, 8 and 9 all contain similar language directed to the same limitation, this common limitation of claims 1, 8 and 9 must be interpreted consistently. See Innova, 381 F.3d at 1119. As described above, each of claims 1, 8 and 9 recites a system or method involving " any bank check." The claims and specification establish that the claimed system and method require not just obtaining information from any bank check, as LML' s proposed constructions suggest, but conducting transactions using any bank

check, as Defendants' proposed construction states. The very first description in the Field of the Invention of the `988 patent states: This invention relates to the field of Point-of-Sale systems and more particularly to the integration and processing of purchases whereby a check is used as the basic source of identification of the individual and of the individual's bank and whereby the bank account is debited. (Ex. X at 1:11-15.) This context is reflected in the `988 patent claims. Claims 1 and 9 recite means for " transferring funds" as part of the claimed system. (Ex. X at 11:54; 12:65.) The term " funds" in this context clearly relates to funds in the account identified by the " bank check" recited earlier in the claims. As described in the specification, the claimed invention enables " point of sale purchases of goods and services paid from consumer funds secured in bank checking or depository accounts." (Id. at 2:66-3:3.) " When the transaction event is `approved' funds are debited from an authorized consumer account for credit to the system subscriber. . . ." (Id. at 3:26-28; see also 8:37-38.)
REDACTED
Accordingly, the " transferring funds" recited in claims 1 and 9 must refer to funds associated with the bank check presented earlier in the claim, namely the " any bank check" recited in claims 1 and 9. Similarly, the " subsequent automated clearing house operations" recited in claim 8 must relate to operations based on the information obtained from " any bank check," as earlier recited in the claim. The specification of the patent-in-suit lends support to Defendants' proposed construction of these phrases, stating that " (o)nce the transaction is approved the central 19

computer captures the MICR information and the sale amount and stores that information 146. The central computer subsequently generates a batch message regarding all transaction events for the prior period and transmits all the transaction event information for the day into the ACH network." (Ex. X at 8:30-35.) Accordingly, the transactions described at end of the process are expressly tied to the bank check provided by the consumer, i.e., the " any bank check" recited earlier in the claims. LML' s proposed constructions wrongly ignore this relationship between the " any bank check" presented earlier in the claims, and the subsequent transfer of funds or automated clearinghouse operations. The `988 patent also makes clear that transactions occur electronically, as set forth in Defendants' proposed construction. The specification states generally that in the `988 patented system, " (f)unding settlement to the system subscriber would be effectuated by means of Electronic Funds Transfer via ACH. . . ." (Id. at 4:23-28.) This statement accords with the means-plus-function language of claims 1 and 9, which describe communications by a computer, which would be understood to occur electronically: " second communication means enabling said central computer system to communicate . . . ." (Id. at 11:49-51, 12:60-62.) The overall context of the claims and specification support Defendants' proposed construction, as they relate to transactions " whereby the bank account is debited," each transaction is an " electronic or `paperless' event," and electronic funds transfer is enabled for " personal or corporate" checks. (Id. at 1:15, 3:3-7.) All intrinsic sources establish that these limitations should be interpreted to require mean " electronically communicating with an automated clearing house for transferring funds electronically based upon the consumer bank account information obtained from any bank check presented at the point of sale."

Interpretation of Disputed Claim Terms Relating to " Negotiable Instrument" 1. Claims 1, 8 and 9: " without using the bank check as a negotiable instrument" and corresponding limitations mean " the bank check (or `the check'), at no time, takes on the status of a negotiable instrument"
Independent claim 1 of the `988 patent includes the negative limitation " without using the check as a negotiable instrument." (Ex. X at 11:54-55.) This phrase, as used in claim 1, should be construed to mean that " the bank check, at no time, takes on the status of a negotiable instrument." Similarly, claim 8 recites " without using the check as a negotiable instrument," and claim 9 recites " without using a bank check as a negotiable instrument." These phrases should be construed to mean " the check, at no time, takes on the status of a negotiable instrument." These consistent constructions are appropriate for these similar phrases in claims 1, 8 and 9. See Innova, 381 F.3d at 1119. For purposes of clarity and convenience, Defendants' proposed constructions are discussed together below using the form " the (bank) check, at no time, takes on the status of a negotiable instrument."

LML now asserts that the limitation should be interpreted to mean " where the paper check is used as a source of information, and is not accepted or processed." (Ex. A.)
REDACTED Instead, LML' s proposed construction has progressively morphed into whatever definition is needed at a given moment. In contrast, Defendants' construction is supported by the `988 patent itself and its intrinsic record REDACTED
a.
The `988 specification supports Defendants' proposed construction of the negative limitation " without using a bank check as a negotiable instrument"
The specification of the patent-in-suit supports the Defendants' proposed interpretation of the phrase " without using a (bank) check as a negotiable instrument." This definition is consistent with the specification' s statement that " (n)one of these (prior art) systems completely does away with the need and use for a negotiable draft instrument while using the consumer' s bank check for identification and verification only." (Ex. X at 2:52-55.) The specification recites that, preferably, a " specimen" or " blank" check is used to initiate transactions, i.e. a check that is neither filled out nor signed. (Id. at 7:46-48.) 22
Case 1:04-cv-00858-SLR
Document 290
Filed 10/14/2005
Page 30 of 46
Such a check would never take on the status of a negotiable instrument, as reflected in Defendants' proposed construction. The specification also seeks to distinguish the Case reference by characterizing it as requiring the use of a draft negotiable instrument, stating that the Case system compels the customer to inscribe his or her check with the " amount, along with a signature and other information. . . ." (Id. at 2:5-12.) This information is the type that would give rise to the status of a negotiable instrument. The specification provides no other definition of the phrase " without using the (bank) check as a negotiable instrument" to give it meaning separate and apart from this plain and ordinary one. b. The prosecution history supports Defendants' construction
The prosecution history further supports Defendants' construction of these phrases. Each independent claim was narrowed by amendment to include the phrase " without using the bank check as a negotiable instrument" or the corresponding phrases of claims 8 and 9. This narrowing amendment acts as a disclaimer of any system or method in which the check takes on the status of a negotiable instrument. During prosecution, the Applicants specifically argued that the `607 patent to Carlson uses the check as a negotiable instrument. (Ex. I at LML-EP-000192-94.) The `607 patent, however, teaches that a check may be scanned to obtain consumer bank account information (Ex. S at 6:38-52), that the information may be used to verify the check and transfer funds (id. at 3:35-40; 4:29-42; 24:19-44), and that the check may be returned to the consumer at the point of sale (id. at 18:52-60; 25:4-7). The only difference in this overall process is that Carlson teaches that the consumer provides a " negotiable instrument" to the merchant. REDACTED
Based on this intrinsic record during prosecution, the only reasonable construction of the phrase " without using the bank check as a negotiable instrument," and the 23
Case 1:04-cv-00858-SLR

corresponding phrases in claims 8 and 9, is that " the bank check, at no time, takes on the status of a negotiable instrument." Any broader meaning was lost when the claim was narrowed by amendment. REDACTED Any such broader interpretation was disclaimed during prosecution in an effort to overcome Carlson and similar prior art references. c. REDACTED
LML's proposed construction of " without using the bank check as a negotiable instrument" is improper
LML and its expert suggest a number of definitions for this phrase, suggesting that the limitation " without using the bank check as a negotiable instrument" is met when a check is used to obtain information and then returned to the consumer at the point of sale. Such a construction is erroneous for several reasons. First, LML' s proposed construction renders the asserted claims containing this limitation invalid. As set forth above, the Carlson `607 patent teaches that a check may be returned to the consumer at the point of sale. (Ex. S at 25:4-7.) REDACTED
Another prior art reference, the `682 patent to Higashiyama, also describes returning the check to the consumer at the point of sale (Ex. T at 4:54-68),

The use of this untimely evidence is wholly inconsistent with wellsettled principles of claim construction requiring that claims be interpreted within their appropriate temporal context. See, e.g., Phillips, 415 F.3d at 1313. D. Interpretation of Disputed Claim Terms Related to the " Sole Purpose" of Obtaining " Consumer Bank Account Information" 1. Claims 1-3, 8 & 9: " consumer bank account information" means " only the ABA/transit routing number and bank account number"
Claims 1, 2, 3, 8 and 9 of the `988 patent each contain the phrase " consumer bank account information" when referring to the information read by the point of sale terminal from a customer' s bank check. (Ex. X at 11:37-38, 44-45, 61-62, 65-67; 12:26, 28, 35, 37-38, 43-44, 51-52, 56.) The common term " consumer bank account information" must be construed consistently throughout claims 1, 2, 3, 8 and 9. See Innova, 381 F.3d at 1119. The plain and ordinary meaning of the term " consumer bank account information" is information that identifies a consumer bank account. REDACTED 25
Case 1:04-cv-00858-SLR

Page 33 of 46
Identification of a particular consumer account requires only identification of the bank at which the consumer account is maintained and identification of the individual account maintained by the consumer at that bank, and does not require identification of any particular check associated with that account. As encoded in the MICR line of most consumer bank checks, consumer bank information consists of and should be interpreted to mean the " only the ABA/transit routing number and bank account number." In the parties' Joint Proposed Claim Construction Chart, LML interprets the term " consumer bank account information" to mean " any information relating to a consumer' s bank account including, but not limited to, magnetic ink character recognition numbers." (Ex. A; REDACTED LML thus defines the
check serial number as part of the " consumer bank account information," but this interpretation is inconsistent with the plain and ordinary meaning and the intrinsic record. a. The claim language supports Defendants' proposed construction of the term " consumer bank account information"
The language of the claims of the `988 patent provide context and meaning to the phrase " consumer bank account information." As described in dependent claims 3, 5 and 11 of the patent-in-suit, " consumer bank account information" is that information shown on the terminal' s display for verification of the customer' s account number and used for subsequent verification of account status. (Ex. X at 11:64-67; 12:6-10; 13:6-10.) The specification describes in detail that those numbers are the customer' s ABA/transit routing and bank account number, and this is the only information required to identify a given bank account. b. The specification supports construction of " consumer bank account information" to mean " ABA/transit routing number and bank account number
The `988 patent specification further supports construing " consumer bank account information" to mean only the ABA/transit routing number and bank account number. The specification provides that the claimed system captures the MICR numbers printed 26
Case 1:04-cv-00858-SLR

on a consumer' s bank check (Id. at 7:57-61), and the " MICR interface results in the transmittal of a query for data center approval of the entire ABA/Transit and personal or corporate checking account numbers." (Id. at 10:29-31.) The specification does not teach that the check number is captured or transmitted during the approval or payment process. In other words, while the check serial number is part of the broader set of " MICR information," it does not constitute part of the subset of " MICR information" consisting of only " consumer bank account information." LML' s construction of this limitation improperly conflates the separate terms " MICR information" and " consumer bank account information." REDACTED
The `988 specification is specific about what information constitutes " consumer bank account information, stating that " ACH settlement criteria mandate exact recall for the bank and checking account numbers to properly complete any debit request." (Ex. X at 10:49-51.) It is the " ABA and account numbers," not the check' s serial number, that must be displayed for accuracy. (Id. at 10:33-39.) Likewise, it is the check' s " bank/checking account information" that is used by the system' s central computer to determine whether the customer' s account is in good standing. (Id. at 9:17-21, 37-42.) The " consumer banking information" depicted on the sales slip shown in Figure 9 also does not include a check serial number. (Id. at Fig. 9.) Moreover, the Abstract of the `988 patent describes that the " consumer bank information" may be encoded on a plastic card. " Point-of-sale terminals are designed to accept a form of credit card with a consumer' s bank account information encoded thereon." (Ex. X at LML-EP-000063) No such plastic card would contain a check serial number, lending further support to Defendants' construction of " consumer bank account information" as including only the ABA/Transit number and bank account number.

In fact, the `988 patent expressly describes disregarding the check serial number when it is included in MICR information. " Instances where printed checks add the individual' s check number to the end of the account number can be `dropped' by Check Reader switch settings." (Id. at 10:31-34.) The distinction drawn in the specification between the check' s serial number on the one hand and the ABA/transit routing number and bank account number on the other hand is reflected in Defendants' construction of the term " consumer bank account information." Nothing in the specification assigns a special definition to the term " customer bank account information" that would deviate from the plain and ordinary meaning it would be given by one of ordinary skill in the art. The specification instead repeatedly defines " customer bank account information" as only the ABA/transit routing number and bank account number. c. The prosecution history supports Defendants' proposed construction
The `988 prosecution history confirms that " consumer bank account information" should be construed to mean " ABA/transit routing number and bank account number." In their September 23, 1993 Response to Office Action, Applicants argued that in the purported invention, " checking account information is simply read from the check." (Ex. C at LML-EP-000157.) Applicants stated further in an October 28, 1994 Response to Office Action that the " point of sale terminal accepts bank account information by reading the MICR information from any bank check." (Ex. H at LML-EP-000189; see also Ex. L at LML-EP-000215-16.) This disparate use of the terms " bank account information" and " MICR information" confirms that the two terms have different meanings. Whereas the MICR information may include all the information on the MICR line, including the check serial number, the " consumer bank account information" includes only the subset of that information that identifies the bank account. The prosecution history thus confirms that 28

" consumer bank account information" should be construed to mean " only the ABA/transit routing number and bank account number." d. Extrinsic evidence conforms to Defendants' proposed construction of this phrase
REDACTED
The information that identifies the " source depository account" is simply the bank number (ABA/Transit number) and the account number. Defendants' construction is also consistent with the fact that in the system and method of the `988 patent, the same check can be used over and over again
REDACTED
This feature demonstrates that the check serial number does not constitute " consumer bank account information," because if the check serial number were utilized by the system to identify or otherwise affect the transaction, then a single check could not be used to complete more than one transaction. 2. Claims 2, 8 & 9: " for the sole purpose"
Dependent claim 2 and independent claims 8 and 9 describe means for reading MICR information appearing on a consumer bank check " for the sole purpose" of gathering consumer bank account information. (Ex. X at 11:56-61; 12:25-28, 43, 53-56.) In the parties' Joint Proposed Claim Construction Chart, LML proposes that the limitation " for the sole purpose" be interpreted, in the context of all three claims, to mean " for the only purpose." (Ex. A; REDACTED) There is no basis for this
unilateral change from the ordinary meaning of the phrase " sole purpose." While 29

Defendants provided an alternative construction of this phrase as part of its construction of a broader element, agreement on the broader element focused discussion on the simple phrase " for the sole purpose." Standing alone, this phrase needs no construction, and LML' s attempt to modify this straightforward language should be rejected. a. The `988 prosecution history supports Defendants' interpretation of these limitations in claims 2, 8 and 9
The " sole purpose" limitation was added to claim 2 during prosecution in a June 8, 1994 Preliminary Amendment. (Ex. G at LML-EP-000173.) In the same Preliminary Amendment, Applicants added claim 8 (Ex. G at LML-EP-000174-76), and later described that claim in a January 3, 1995 Response to Office Action as a " point of sale process comprising . . . reading MICR information from the check for the sole purpose of obtaining bank account information. . . ." (Ex. I at LML-EP-000189). Throughout the same Response, Applicants repeatedly sought to distinguish the claimed invention over the asserted prior art by stating that none of those references " disclose the use of any bank check solely to derive consumer information and not for use as a negotiable instrument." (Id. at LML-EP-000190-206.) Summarizing their efforts to overcome the asserted prior art, Applicants argued in their January 30, 1995 Response that " none of the references discloses a point of sale system that uses any bank check solely for the purposes of gathering customer information . . . ." (Id. at LML-EP000207.) Each of these arguments confirms that the phrase " for the sole purpose" would be understood to obtain its plain and ordinary meaning to one of ordinary skill in the art. E. Interpretation of Disputed Claim Terms Relating to Account Verification 1. Claim 8: " verifying that account numbers were accurately read at the point of sale" means " visually confirming that account numbers were accurately read by reference to the source document"
Claim 8 describes a checkwriting point of sale system that includes the step of " verifying that account numbers were accurately read at the point of sale terminal." (Ex. 30

X at 12:30-32.) In accordance with the intrinsic evidence, this limitation instead should be construed to mean " visually confirming that account numbers were accurately read by reference to the source document." The `988 specification states that " logic means further drives a display 324 which provides a visual output of the account number of the consumer for verification." (Ex. X at 7:6-8; see also 9:14-16 (" the terminal' s screen would display th
