MOTION FOR SUMMARY JUDGMENT [NO. 3] OF NON—H•lFRl1*lGEMZENT OF U.S.
I PATENT NO. 5,452,159 ‘
I, David B. Bogy, PhD., state and declare as follows: .
1. I am an independent technical consultant. I have been retained by counsel for l
Seagate Technology LLC ("Seagate”) as an expert in the above-captioned matter. My
education, knowledge, and relevant eirperience are summarized in the curriculum vitae, attached ·
hereto as Exhibit 1. - ` E
2. 'This declaration is in support of Seagnte’s Brief In Opposition To Comioe’s
` Motion For Summary Judgment [No. 3] Of Non-Infringement Of U.S. Patent No. 5,452,159
("tI1e ‘159 patent"). . E
3. I have reviewed the *159 patent and its ile history and have set forth my opinions
s regarding injriingement and validity ofthe ‘ 159 patent in expert reports tiled in this litigation
` I 4. I In accordance with my initial expert report, Ibelieve thatthe 1.0 GB SE, 1.5 GB
. SE, and 2.0 GB SE disc drives infringe claims 1, 2, 3, and 4 ofthe *159 patent under the doctrine
of equivalents because, in my opinion, the magnetic latch assemblies perform substantially the
same function, in substantially the same way, to achieve substantially the same result as the · l
claimed magnetic parking device. Moreover, to the extent any differences exist between the 1.0

GB SE, 1.5 GB SE, and 2.0 GB SE disc drives and claims 1, 2, 3, and4 ofthe ‘159 patent, such
i differences are insubstantial.
5. The function of “parking” the actuator/i1ead(s) is to maintain or Hx the position of
. the actuator/head(s) so that the head(s) does not come into contact with a data portion of the disc ·
when the disc drive is not operating or during shock events, like someone dropping the drive on
the floor, or other words, protect head(s) and data portion of the disc Hom damage.

8. The "resu1t” of parking the actuator/head(s) is a disc drive that experiences less
drive failtnes caused by the head(s) contacting the disc. . " _ I
- 9. Based on my understanding of Cornice’s proposed deiinition of "park," and in
accordance with my expert report, Ibelieve a reasonable tact Ender would likely End at least
G inmngement under the doctrine of equivalents given the insubstantial changes between
Cornice’s devices and the claimed invention. U V
I declare under penalty of perjury under the laws ofthe United States of America that the
. foregoing is true and correct Executed this [5 Mday of December, 2005, inIBerlceley,
