Defendant Dexter Chasis Group, Inc. ("Dexter"), in response to Lippert Component Inc.'s Opening Brief on Claim Construction filed on September 14, 2008 ("Lippert's Brief"), states as follows: I. INTRODUCTION
Lippert's claim construction is legally and factually deficient in numerous respects. Most glaring is Lippert's consideration of the specification last in its claim construction analysis. As noted in Dexter's Opening Brief, the Federal Circuit's en banc Phillips decision returned the specification to the primary source for determining the meaning of claim terms. Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed. Cir. 1005) See also, On Demand Machine Corp. v. Ingram Industries, Inc., 442 F. 3d 1331, 1337 (Fed. Cir. 2006). In doing so, the Federal Circuit resolved a conflict between numerous panel opinions. On Demand, 442 F.3d at 1337. Lippert ignores Phillips, and first refers to everything but the specification to arrive at an overly broad meaning of "slidably mounted." See Lippert's Brief, pp. 6 - 14. When it finally pays lip-service to the specification, under the heading "The Intrinsic Evidence Further Supports...," Lippert attempts to obscure the claimed manner in which the "movable member" or "slide plate" and the "stationary member" or rails must be connected, that is "slidably mounted." Lippert Brief, p. 14. Lippert attempts to have the Court focus on the drive mechanism (which, in one embodiment, has a spur gear that rotates), while construing the term "slidably mounted." However, the drive mechanism, including a rotating spur gear, is not even included in independent claims 1, 7, 13, 17, 18, 21, and 22, and has nothing to do with the claim limitation "slidably mounted," which modifies how the slide plate (or "moveable member") and rails (or stationary member) must be connected together. 1

II. A.
DISCUSSION
Lippert Improperly Relied on Everything But the Specification.
Because it cannot prevail in its construction of "slide" by relying as it should on the specification as the primary source of meaning for claim construction, Lippert proceeds by first relying on a relatively obscure dictionary definition ("Wordnet", Lippert Brief, p. 11); second, relying on an extrinsic article regarding the "RV" industry that is not authenticated and copyrighted in 2002, six years after the relevant date for interpreting the claims, that is, 1996, the filing date; third, relying on cited and uncited prior art patents; and last, only after arguing all of the above, Lippert discusses the specification, albeit in a misleading way. Lippert's Brief, pp. 14 15. Lippert's "specification-last" approach is clear from the heading -- "The Intrinsic Evidence Further Supports LCI"s Construction." Lippert's Brief, p. 14 (emphasis added). Lippert's approach is contrary to the Phillips decision, 415 F.3d at 1315-16 (Fed. Cir. 2005). Prior to Phillips, "conflicting Federal Circuit panel opinions were producing uncertainty as to the law of claim construction." On Demand, 442 F. 3d at 1337. The On Demand court further stated: This court in Phillips emphasized that the proper judicial construction of a claim and its terms is from the viewpoint of a person of ordinary skill in the field of the invention; a court must determine how such a person would understand the claim in the context of the particular technology and the description in the specification, with due reference to the prosecution history. Thus the court in Phillips, resolving conflict, stressed the dominance of the specification in understanding the scope and defining the limits of the terms used in the claim. Id. at 1337 1338 (emphasis added). In view of the Federal Circuit's explicit instruction that the specification dominates claim construction, Lippert's saving of the specification to last (page 18 of its 23 page Brief) is legally incorrect. 2

The cases cited by Lippert are not controlling. For example, Lippert cited to CCS Fitness, Inc. v. Brunswick Corp, 288 F. 3d 1359 (Fed. Cir. 2002), a case decided before Phillips. Contrary to Phillips, CCS Fitness emphasized a "dictionary-first" approach.1 Under this over-ruled approach, the patentholder would first seek meaning from dictionaries, point to many different definitions all depending on context, and then argue that it was entitled to all of the definitions. See CCS Fitness at 1366. The Phillips decision expressly rejected this approach. See Acumed LLC v. Stryker Corp., 483 F.3d 800, 809 (Fed. Cir. 2007); Phillips, 415 F.3d at 1319 1324; Dexter Brief, p. 7. Lippert uses the approach found in CCS Fitness, among others, and rejected in Phillips. It refers first to a single dictionary definition, cited patents, and extrinsic evidence without reference to the specification; asserts a very broad definition of "slide"; then argues that the term must be given the broad definition without regard to the context of how the terms "slidably mounted" and the word "slidably" (and its variations) are used in the specification. Lippert attempts to raise the specter of "reading limitations from the specification into the claims" Lippert Brief, p. 6. This argument is a red-herring since one cannot "read-in" a limitation that was selected by the inventor and already present in the claims. Phillips instructed courts to embrace the specification in claim interpretation, not to refer to it as a last resort. "In general, the scope and outer boundary of claims is set
As another example of Lippert's use of out-dated case law, all of the cases cited in the heading "Claims Must be Read in Light of the Specification, But The Specification Does Not Establish the Boundaries of the Claim", are all pre-Phillips. The most recent, the Playtex Prod., Inc. v. Proctor & Gamble Co. , 400 F.3d 901 (Fed. Cir. 2005) case, issued in March, 2005, before Phillips, which was decided in July 2005. Attempting to reconcile pre-Phillips cases is a useless exercise; the Federal Circuit in Phillips acknowledged that there was conflict between panel opinions, and resolved the conflict.

by the patentee's description of his inventions." On Demand, 442 F3d. at 1331 (citing Phillips, 415 F.3d at 1313). Construing "slidably mounted" broadly to include a connection between the slide plate and rails that enable a rolling motion in spite of the narrow usage of that term in the specification would provide patent coverage that is broader than what the inventor actually invented and disclosed in his specification. As Lippert notes, it is true that claims should not automatically be limited to the preferred embodiment. However, "[o]ne does not receive entitlement to a period of exclusivity for what one has not disclosed to the public. ... But merely calling an embodiment "preferred," when there are no others, does not entitle one to claims broader than the disclosure." Lizardtech, Inc. v. Earth Resource Mapping, Inc., 433 F.3d 1373, 1375 (Fed. Cir. 2006). Contrary to Lippert's contentions, Dexter's interpretation of the word "slidably," is not reading a limitation into the claim. See Lippert's Brief, p. 6. Consistent with Dexter's approach to claim construction, all of the following postPhillips cases involved interpreting a common word by first looking at its usage in the specification, then looking to a dictionary to confirm the meaning found therein based on the context provided by the specification. The specification must be the starting point for claim construction. For example, in Nystrom v. TREX, Co., the court stated: [i]n the absence of something in the written description and/or prosecution history to provide explicit or implicit notice to the public-i.e., those of ordinary skill in the art-that the inventor intended a disputed term to cover more than the ordinary and customary meaning revealed by the context of the intrinsic record, it is improper to read the term to encompass a broader definition simply because it may be found in a dictionary, treatise, or other extrinsic source. 424 F.3d 1136, 1145 (Fed. Cir. 2005). Moreover, in Primos, Inc. v. Hunter' Specialties, Inc., s 4

451 F.3d 841, 845, 847-48 (Fed. Cir. 2006), the Federal Circuit affirmed the district court' claim s construction of the word "engaging". In that case, the district court rejected a dictionary definition that was broader and inconsistent with the use of the claim term in the patent at issue. Id. at 845. In Old Town Canoe Co. v. Confluence Holdings Corp., 448 F.3d 1309, 1318 (Fed.
Cir. 2006), the court held that the patentee is "not entitled to a claim construction divorced from the context of the written description and prosecution history." The district court properly interpreted the term "coalescence" by reviewing the dictionary definitions and the context of its usage in the specification and prosecution history. The court in Atofina v. Great Lakes Chem. Corp., 441 F.3d 991, 996 (Fed. Cir. 2006) looked to a dictionary for assistance where the word "catalyst" was not defined in the intrinsic record. The court quoted Free Motion Fitness, Inc. v. Cybex Int' Inc., 423 F.3d 1343, 1348-49 l, (Fed. Cir. 2005) for the proposition that "in those circumstances where reference to dictionaries is appropriate, the [court' task is to scrutinize the intrinsic evidence in order to determine the s] most appropriate definition " (emphasis added). Atofina, 441 F.3d at 996. The court in In re Johnson, 435 F.3d 1381, 1384 (Fed. Cir. 2006) cited Phillips, 415 F.3d at 1303, for the proposition that "[i]t is well established that dictionary definitions must give way to the meaning imparted by the specification. Finally, in NetworkCommerce, Inc. v. Microsoft Corp., 422 F.3d 1353, 1359-60 (Fed. Cir. 2005), the court rejected a proposed construction of the term "download component" based on the combination of two dictionary definitions as untenable "in light of the specification." As shown by these cases, claim terms must be interpreted using the specification first, and dictionaries may be consulted thereafter to assist in the interpretation.

The inventor's statements in the specification as to what "the invention" is, further supports Dexter's interpretation. The inventor described "the invention" as a "slide plate" that is "slidably secured" (i.e., slidably mounted") to "rails." While the patentee sought to expand the definition of "his invention" slightly by stating that "a wide variety of structure" was included, he then went on to limit "his invention" to a stationary member to which a "second member" "is mounted for slidable movement relative to the stationary member," "such as a tube within a tube or other systems known in the art." `715 Patent, Co. 8, ll. 76-32. From this description, the inventor limited the invention to a mechanism that consists of (1) a slide plate and rail or (2) "tube within a tube" systems. Both of these mechanisms involve the movement of one surface relative to and in constant contact with another. The reference to "other systems known in the art" is mere boilerplate that does not serve the public notice function, and furthermore, is encompassed within the context of the stationary member and a second member mounted for "slidable movement." "When a patent thus describes the features of the `present invention' as a whole, this description limits the scope of the invention." Verizon Services Corp. v. Vonage Holdings Corp., 2007 WL 2781869, *10 (Fed. Cir. 2007) (citing Honeywell Int'l., Inc. v. ITT Indus., 452 F.3d 1312, 1318-19 (Fed. Cir. 2006)). By describing "the invention" as limited to mechanisms with a "second member" mounted to a "stationary member" for "slidable movement," one skilled in the art would have no reason to think that the inventor meant to include other types of movement, such as rolling. Hence, Dexter's construction of "slidably mounted" does not limit the inventor to the preferred embodiment of a slide plate and rail, as Lippert argues. Instead, Dexter's interpretation 6
Case 1:06-cv-00762-JJF
Document 32
Filed 10/05/2007
Page 11 of 20
gives the inventor the full breadth of his disclosure, which also includes a "tube with a tube" system. Dexter's construction of "slidably mounted" is consistent with the usage in the specification and is supported by a number of well-respected dictionaries. The patentee could have simply said "mounted." He did not. He could have said "moveably mounted" to include all kinds of motion. He did not. Instead, he chose a particular type of motion, sliding ("slidably"), which means a surface moving in constant contact with a stationary surface. This is far different than a rolling motion. In fact, at least one dictionary defines sliding as "not rolling" (see Dexter's Brief, p. 13, Ex. J, K). Because the dictionary definition of "slidably" is consistent with the use of the term in the specification, there is no need to go to other intrinsic or extrinsic evidence. Nevertheless, the remaining intrinsic and extrinsic evidence that is relevant and admissible further supports Dexter's interpretation. B. Lippert's Late Discussion of the Specification Is Misleading
Even when Lippert does discuss the specification in connection with "slidably mounted," it deliberately confuses the "drive means" with the moveable member (or slide plate) and the support member (or rail) which are "slidably mounted." See Lippert Brief, p. 15. One of the several "drive means" described in the patent is a rotating spur gear (`715 Patent, Col. 6, ll. 4345), along with "hydraulic pistons, chain drives, screw gears, scissor jacks, or manual means." (Col. 6, ll. 42-43). Lippert attempts to associate the rotating spur gear with the limitation "slidably mounted" and argues disingenuously that "slidably mounted" can include rollers. However, the "slide plate" or "moveable member" must be "mounted" to the "support member." 7
Case 1:06-cv-00762-JJF
Document 32
Filed 10/05/2007
Page 12 of 20
These structures exist apart from whatever "drive means" (of the several listed in the specification) a designer would choose to move the slide plate or movable member with respect to the support member. The "slidably mounted" limitation has nothing to do with the "drive means" and, in particular, the rotating spur gear. Thus, the mention of a rotating spur gear sheds no light on the meaning of "slidably mounted." C. Discussion of Lippert's Use of Other Patents
Lippert argues that "a number of third party patents addressing related inventions further illustrate the understanding of the term `slide' within the RV industry... ." Lippert Brief, p. 12. Contrary to Lippert's representation, the Vitalini patent has nothing to do with the "RV" industry. It concerns a "Building Having a Telescopic Section." Lippert's Brief, Ex. 4. The DeBiaggio patent does disclose a "slideout mechanism," and one of the embodiments utilized rollers, but it also discloses a "tube within a tube" structure where two surfaces slide over one another. See Lippert's Brief, Ex. 5, Fig. 24. All that can be said is that the DeBiggio patent uses the term "slidably" inconsistent with not only the specification of the `715 Patent but also the dictionary definition of "slide." A thorough study of the cited art demonstrates one thing--the inventor knew about rollers in connection with extendable rooms, yet failed to mention them as alternative embodiments as he did with the "tube within a tube" system. Extendable rooms for campers or recreational vehicles are very old in the art. See Dexter's Brief, Ex. B, Ex. 1, 2,225,319 Patent, issued in 1940; Ex. D, 2,606,057 Patent, which issued in 1952. The designs shown in these and other cited patents utilized rollers to some degree as part of the mechanism for extending and retracting the room, yet the rooms were not referred to as "slide-out" rooms. For example, 8

Page 13 of 20
United States Patent No. 4,500,132 (Ex. L attached hereto)2 shows an extension mechanism (telescopic extension members 43) that resembles the slide plate or tube-within-a-tube structures described in the `715 Patent and did not utilize rollers. United States Patent No. 5,237,782 uses the word "slide-out" to describe an assembly using a "tube within a tube" structure that slides, i.e., relative movement with continuous surface to surface contact. Ex. M, Figure 3; Col. 4. Likewise, the following cited references use "slide" or "slide-out" in connection with extension mechanisms in which two surfaces move in continuous, surface to surface contact. See Ex. N, United States Patent No. 5,577,351 (describing a tube 48 "slideably received" within a tube 46 (Col. 2, ll. 37-39)); Ex. O, United States Patent 5,491,933 (inner and outer support tubes (Col. 5, ll. 5-10)); Lippert's Brief, Ex. 5, United States Patent No. 5,620,224 (Col. 8, ll. 48-59; stationary channel members 253 and frame members 254 "slidably and telescopingly engage" one another). A few of the cited patents disclose rollers (e.g., `319 Patent, issued in 1940, the `224 Patent, and the `276 Patent), but, the inventor did not mention rollers as alternative embodiments. Perhaps the most telling references as to the meaning of the claim terms are the nonpatent art, that is, the two drawings from Peterson Industries. Ex. P. In each of these, the inventor labeled the drawings "Slide out mechanism", and also labeled each part, including a "slide plate." The mechanism shown in these drawings is a slide plate having a surface which moves in constant contact over the surface of a support member. Hence, the cited art as a whole supports Dexter's interpretation.

The last Exhibit to Dexter's Brief was Ex. K. Hence, the first exhibit to this Response is Ex. L. 9

The cited art demonstrates that, in this old and crowded field, the inventor claimed a very particular type of extension apparatus.3 The inventor of the `715 Patent knew of the prior art, yet, even though the use of rollers were well-known, he chose to limit his claims to mechanism that was "slidably mounted." He did not disclose rollers, even though he did disclose the slide plate (e.g., as shown in the Peterson drawings), and also a "tube within a tube" structure. Hence, one skilled in the art would have no reason to conclude that "slidably mounted" meant anything other than the dictionary definition which consists of two surfaces moving with respect to one another in constant contact. D. Discussion of Lippert's Submission of Dexter's Drawings
Lippert improperly attempts to inject infringement issues into claim construction by its discussion of the Dexter drawings. Lippert Brief, p. 16. The Federal Circuit, as noted in In addition, it is important to remember that "[i]n general, the scope and outer boundary of claims is set by the patentee's description of his inventions." On Demand, 442, F. 3d at 1331 (citing Phillips, 415 F.3d at 1313); Lizardtech, 433 F.3d at 1375 (Fed. Cir. 2006). The inventor did not incorporate by reference into the specification any of the patents relied upon by Lippert. Even in cases where the inventor explicitly attempted to "incorporate by reference," the Federal Circuit still found that the references were not part of the disclosure. See In re Modine Manufacturing Company, 18 Fed. Appx. 857, *3 (Fed. Cir. 2001) (finding that the written description requirement was not met by a patent that was incorporated by reference, but not in a way that made it clear that the claimed range for a certain dimension was part of the application); See also Atmel Corp. v. Information Storage Devices, Inc., 198 F.3d 1374, 1381 (Fed. Cir. 1999) (deciding that "the inquiry is whether structure is described in the specification" and not whether it is "incorporated by reference) (emphasis in original); See generally Advanced Display Systems, Inc. v. Kent State University, 212 F.3d 1272 (Fed. Cir. 2000) (holding material must be cited "in a manner that makes clear that the material is effectively part of the host document as if it were explicitly contained therein...the host document must identify with detailed particularity what specific material it incorporates and clearly indicate where that material is found in the various documents"). Hence, the disclosure of the `715 Patent does not include the cited patents as part of the patentee's disclosure describing his inventions. 10

Dexter's Brief (p. 2, n.2), has recently held that the accused product provides context for claim construction. See Wilson Sporting Goods Co. v. Hillerich & Bradsby Co., 442 F.3d 1322, 132627, 1331 (Fed. Cir. 2006); See Lava Trading, Inc. v. Sonic Trading Management, LLC, 445 F.3d 1348, 1350 (Fed. Cir. 2006). The purpose for doing so is to insure that the court is not merely issuing an advisory opinion. See Lava, 445 F.3d at 1350. However, this purpose was accomplished by the introduction of photographs of the accused products. Dexter's Brief (pp. 23,10). Lippert transcended the law by submitting Dexter's drawings of Exhibit 10 and discussing them in connection with claim construction. See Wilson., 442 F.3d at 1330-31 (quoting NeoMagic, Corp. v. Trident Microsystems, 287 F.3d 1062, 1074 (Fed. Cir. 2000) ("It is well settled that claims may not be construed by reference to the accused device.")). Furthermore, the drawings of Exhibit 10 are dated 2004 and 2006, but the relevant date for claim interpretation is 1996. How a person skilled in the art would use the word "slide" to describe the entire structure in 2004 or 2006 is entirely irrelevant. Furthermore, how the entire assembly is described has no bearing on the meaning of the claim term "slidably mounted." E. "Moveable Member" is a Means-Plus-Function Limitation
As expected, Lippert lumps all of the "member" elements found in the claims, "moveable member," "stationary member", and "support member," together, and argues that Dexter's position is inconsistent. The point Lippert misses or deliberately avoid is that "moveable member" is a claim term that is not found in the specification. Lippert's argument was addressed in footnote 4 of Dexter's Brief. As Lippert notes, numerous "members" are described in the specification: "stationary member," "retractable member," "slidable member," "support member," "slide member" "frame member," and "angle member." Lippert's Brief, p. 18. 11

However, none of these terms, except for "stationary member" and "support member" are claim terms and are also found in the specification. Noticeably absent from the specification is the term "moveable member." Dexter's position is entirely consistent. By reference to the specification, a person skilled in the art reading the claim terms "stationary member" and "support member" in the context of the specification would have some chance of determining what the inventor claimed by these terms as his invention. The same cannot be said of "moveable member." "Stationary member" is used synonymously in the specification with the word "rail," which are labeled elements 21 and 22. `715 Patent, Col. 8, ll. 33-39; see Dexter's Brief, n. 4. The word "support member" is found in the specification. Further it is foreseen that a wide variety of support legs or members could be used for supporting the rear ends 37 and 38 of the rails 21 and 22 above the floor 15 including support means such as threaded rods with pivotal feet, the rods being threadingly secured to the rails 21 and 22 or rear cross-brace 35. It is also foreseen that in some applications it may not be necessary to utilize a support member for supporting the rear end of the rail or stationary member. It may be possible support the stationary member only at a front end thereof. The fact that the inventor used "member" and "means" interchangeably suggests that "member" should be construed as a "means-plus-function" limitation. Furthermore, because the two claim terms "stationary member" and "support member" are used in the specification, they are not indefinite when interpreted as "rail" (as set forth in Dexter's Brief) as to the former and as support legs as to the latter. The cases Lippert cites are distinguishable. While it is true that in some of the cases upon which Lippert relies, the term "member" has been interpreted as a structural element, in those instances, the claim term was found in the specification. E.g., Lighting World, Inc. v. Brichwood 12

Lighting, Inc., 382 F.3d 1354, 1361 (Fed. Cir. 2004) (construing "connector assembly" as a structural term); Kwik Products, Inc. v. National Express, Inc., 179 Fed. Appx. 34, *38 (Fed. Cir. 2006); Laitram Corp. v. Rexnord, Inc., 939 F.2d 1533, 1536 (Fed. Cir. 1991) (interpreting "cross member," which was found in the specification and illustrated in drawings); Depuy Spine, Inc. v. Medtronic Sofamore Danek, Inc., 469 F. 3d 1005, 1023 (Fed. Cir. 2006); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1360 (Fed. Cir. 2002) (interpreting "reciprocating members," which is found in the specification (as found by a review of the patent at issue). The only case Lippert cites where "member" was not used in the specification but still found to be a structural element is Al-Site Corp. v. VSI International, Inc. 174 F.3d 1308, 1318 (Fed. Cir. 1999). This case is distinguishable because the court found that there was sufficient structure in the claims themselves for performing the claimed function. Al-Site Corp., 174 F.3d at 1318.4 In contrast, there are no additional structures set forth in the claims of the `715 Patent to perform the claimed functions. Here, the terms "moveable" and "moveable member" are noticeably absent from the specification is "moveable" and "moveable member." The claimed function, "for securement of the slide-out room thereto..." is found in the specification, and is associated with the structure of a slide plate as further discussed in Dexter's Brief (pp. 17-19). As noted above in connection with the discussion of "support member," the inventor used "member" and "means" interchangeably in the `715 Patent. As shown by the highly analogous case, Mas-Hamilton

"[A]lthough these claim elements include a function, namely, `mounting a pair of eyeglasses,' the claims themselves contain sufficient structural limitations for performing those functions. As noted above, claim 1 of the `345 patent describes the eyeglass hanger member as `made from flat sheet material' with an `opening means formed ... below [its] upper edge.' This structure removes this claim from the purview of § 112, ¶ 6." 13

Group v. LaGard, Inc., 156 F.3d 1206, 1215 (Fed. Cir. 1998), cited in Dexter's Brief, where the word "member" is followed by a functional term and is not found in the specification, it should be interpreted under Section 112(6). Hence, the term "moveable member" must be interpreted under Section 112(6). Alternatively, the term "moveable means" should be found invalid for
indefiniteness, lack of written description, and/or lack of enablement. F. Lippert's Description of "One of Ordinary Skill in the Art" is Incorrect and Unsubstantiated Dexter disputes Lippert's description of the level of ordinary skill in the art. Lippert Brief, p. 10. The level of experience and education is overstated. Furthermore, the "level of one skilled in the art" is a fact question and Lippert's assertion is completely unsupported by any evidence. Graham v. John Deere, 383 U.S. 1, 17 (1966). In relatively simple technologies such as this, expert testimony for claim construction is unnecessary. See J. P. Peta, Inc. v. Club Protector, 65 Fed. App. 724, 2003 WL 21206079, *3 n.2 (Fed. Cir. 2003). The parties even agreed that expert testimony in this case would be unnecessary for claim construction. Lippert's injection of a fact question that would require expert testimony to resolve is inconsistent with this agreement.5 III. CONCLUSION
For all of these reasons, Dexter respectfully requests that the Court adopt Dexter's proposed claim construction as set forth herein.
Nevertheless, in the event the court determines that expert testimony is desirable to resolve this fact issue, Dexter requests leave to submit extrinsic evidence of the "level of one skilled in the art." 14
