`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`Introduction
`Wintek Corporation (“Petitioner”) requests inter partes review of all claims
`
`1-68 of U.S. Patent No. 8,217,902 (“the ’902 Patent”) (Ex. 1001) assigned on its
`
`face to TPK Touch Solutions Inc. (“Patent Owner”). This Petition shows by a
`
`preponderance of the evidence that there is a reasonable likelihood that Petitioner
`
`will prevail on all claims of the ’902 patent based on prior art that the Office did
`
`not have before it or did not fully consider during prosecution, and that anticipates
`
`or renders obvious the claims of the ’902 patent. Claims 1-68 of the ’902 patent
`
`should be found unpatentable and canceled.
`
`II. Mandatory Notices Under 37 C.F.R. § 42.8
`Real Party-In-Interest: Wintek Corporation is the real party-in-interest.
`
`Related Matters: An ex parte reexamination request (Control No.
`
`90/012,869) for the ’902 patent was filed on May 17, 2013, which the U.S. Patent
`
`and Trademark Office (“Office”) granted on June 20, 2013. That reexamination
`
`request involved some of the same prior art at issue in this Petition and remains
`
`pending before the Office. Exhibit 1003 includes a copy of the reexamination
`
`request. Exhibit 1004 includes a copy of the Office’s order granting reexamination.
`
`Petitioner has filed concurrently with this petition another petition for inter
`
`partes review of the ’902 patent. Additionally, the Patent Owner has asserted the
`
`’902 Patent against the Petitioner in a patent infringement litigation filed on May
`
`
`
`1
`
`

`

`
`15, 2013 in the Northern District of California (case no. 3:13-cv-2218). That
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`litigation remains pending. To the Petitioner’s knowledge, the ’902 Patent has not
`
`been subject to any post grant review or any prior inter partes review.

`
`VI. Overview of the ’902 Patent
`The ’902 patent issued from U.S. Application No. 11/842,747 (“the ’747
`
`application”) and is directed to a “conductor pattern structure of a capacitive touch
`
`panel,” and a method of constructing such touch panel. Ex. 1001, Abstract, 3:12-
`
`192, 6:17-33. The ’902 patent purports to simplify and reduce the thickness of the
`
`structure of a capacitive touch panel. Id. at 3:53-54.
`
`FIG. 1 of the ’902 patent discloses a conductor pattern structure, which
`
`includes a plurality of first-axis (X axis) conductor assemblies 13, each including a
`
`plurality of first-axis conductor cells 131 and a plurality of first-axis conduction
`
`lines 132, respectively, connecting between adjacent ones of the first-axis
`
`2 Citations to Ex. 1001 refer to column number: line number(s).
`4
`
`
`
`

`

`
`conductor cells 131. See e.g., id., FIG. 1. The structure also includes a plurality of
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`insulation layers 17, made of transparent insulation material such as silicon oxide,
`
`covering respective first-axis conduction lines 132. See id. at 5:14-17, FIG. 2. The
`
`insulation layers 17 do not cover the first-axis conductor cells 131. See id., FIG. 8.
`
`The structure also includes a plurality of second-axis (Y axis) conductor
`
`assemblies 14, each including a plurality of second-axis conductor cells 141 and a
`
`plurality of second-axis conduction lines 142, respectively, connecting between
`
`adjacent ones of the second-axis conductor cells 141. See id. at 5:17-29, FIGs. 1, 2.
`
`Each second-axis conduction line 142 “extends over and across a surface of each
`
`insulation layer 17.” Id. The first-axis and second-axis conductor assemblies 13, 14
`
`and the first-axis and second-axis conduction lines 132, 142 are made of
`
`“transparent conductive film, such as ITO conductive film.” Id. at 5:48-52.
`
`The ’902 patent also describes a method to manufacture a conductor pattern
`
`structure of a capacitive touch panel. See id. at 6:20-67, FIGs. 7-9. Specifically, the
`
`’902 patent discloses “a substrate on which a plurality of first-axis conductor cells
`
`131, first-axis conduction lines 132, signal transmission lines 16a, 16b, and
`
`second-axis conductor cells 141 are just formed.” Id. at 6:20-22, FIG. 7. The ’902
`
`patent further discloses that after this step, “an insulation covering layer 17 is
`
`formed to cover the surface of each first-axis conduction line 132.” Id. at 6:25-26,
`
`FIG. 8. The ’902 patent also discloses that to complete manufacture of the
`
`
`
`5
`
`

`

`
`conductor patter structure, “a second-axis conduction line 142 is formed to connect
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`between each pair of adjacent second-axis conductor cells 141 of the same second-
`
`axis conductor assembly.” Id. at 6:28-32, FIG. 9.
`
`With respect to sensing a touch, the ’902 patent discloses that when a user’s
`
`finger touches the touch panel, “the first-axis conductor cell 131 of the first-axis
`
`conductor assembly 13 and the second-axis conductor cell 141 of the second-axis
`
`conductor assembly 14 . . . induce a capacitor effect therebetween and a signal
`
`caused thereby is transmitted through the signal transmission lines 16a, 16b to the
`
`control circuit” to calculate the position of touch. Id. at 5:64-6:5.
`
`VII. Prosecution History of the ’902 Patent
`During prosecution of the ’747 Application, Applicants amended the claims
`
`to distinguish them over the prior art cited by the Office stating, among other
`
`things, that the claimed conductor cells consisted of a transparent conductive
`
`material. Applicants also argued that the asserted reference, Bolender, disclosed
`
`capacitive sensors consisting of transparent conductive material overlaid by
`
`capacitive sensors consisting of opaque conductive material. See, e.g., Ex. 1002 at
`
`247-249. Despite admitting that Bolender disclosed structures (conductor cells) of
`
`transparent conductive material corresponding to the claimed conductor cells,
`
`Applicants nonetheless argued that Bolender cannot anticipate the claims because
`
`
`
`6
`
`

`

`
`Bolender’s transparent conductor cells are partially overlaid by opaque conductor
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`cells. See, e.g., Ex. 1010, Fig. 6.
`
`Applicants’ representative also discussed proposed amendments to
`
`overcome the prior art of record in an interview with the examiner. Ex. 1002 at
`
`339. The examiner allowed the ’747 application without the proposed amendment
`
`purportedly because the cited prior art did not allegedly disclose the transparent
`
`conductive material limitation. See Ex. 1002 at 340-348. Specifically, in the
`
`reasons for allowance, the examiner noted that Bolender discloses every limitation
`
`of independent claims 1, 6, 17, 25, 32, 35, 42, 44, 46, 53, 58 and 66 except “first-
`
`axis conductor cells and the second-axis conductor cells consist[ing] of a
`
`transparent conductive material.” Ex. 1002 at 346-47.3 As demonstrated in this
`
`Petition, however, that claimed feature was neither novel nor nonobvious in
`
`conductor pattern structures of capacitive touch panels disclosed in the prior art.
`
`Notably, in the pending ex parte reexamination of the ’902 patent, the examiner
`
`agreed that many references that are also asserted in this Petition, including
`
`Fujitsu, Binstead, Honeywell, Bolender, and Miller, raise a substantial new
`
`
`3 The examiner also acknowledged that U.S. Patent Application Publication
`

`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`VIII. Claim Construction
`A claim subject to inter partes review receives the “broadest reasonable
`
`construction in light of the specification of the patent in which it appears.” 37
`
`C.F.R. § 42.100(b). Claim terms are given their ordinary and accustomed meaning
`
`as would be understood by one of ordinary skill in the art. Phillips v. AWH Corp.,
`
`415 F.3d 1303, 1312-13 (Fed. Cir. 2005) (en banc).
`
`The claim term “in a substantially equally-spaced manner” should be
`
`construed under the broadest reasonable interpretation standard. Claims 1, 17, 25,
`
`32, 35, 42, 44, 46, 58, 66, and 68 each include this term in a similar context. For
`
`example, claim 1 recites “a plurality of first-axis conductor cells arranged on the
`
`surface of the substrate along a first axis in a substantially equally-spaced manner”
`
`and similarly “a plurality of second-axis conductor cells arranged on the surface of
`
`the substrate along a second axis in a substantially equally-spaced manner.”
`
`However, it is not clear from the claim language alone whether (1) the distances
`
`between the centers of the adjacent conductor cells are substantially equal or (2)
`
`the distances between the edges of the adjacent conductor cells are substantially
`
`equal. The examples of first-axis and second-axis conductor cells disclosed in the
`
`specification all have the same size, shape, and orientation, and are arranged such
`
`that both the distances between the centers of adjacent conductor cells and the
`
`
`
`8
`
`

`

`
`distances between the edges of the adjacent conductor cells are substantially equal.
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`See, e.g., Ex. 1001, FIGs. 1-2, 5-10. As such, the broadest reasonable interpretation
`
`of this claim term must include both that the distances between the centers of the
`
`adjacent conductor cells are substantially equal or that the distances between the
`
`edges of the adjacent conductor cells are substantially equal. Of course, both
`
`conditions would be true if all the conductor cells have the same size, same shape,
`
`and same orientation, but the claims do not explicitly recite such requirements.
`
`Therefore, the broadest reasonable interpretation of the claim term “in a
`
`substantially equally-spaced manner” in light of the specification is that “the
`
`distances between the centers of adjacent conductor cells or between the edges of
`
`adjacent conductor cells are substantially equal.”
`
`The remaining terms in claims 1-68 should be given their plain and ordinary
`
`meaning under the broadest reasonable interpretation standard.
`
`IX. Detailed Explanation of Grounds for Unpatentability Under the
`Broadest Reasonable Construction
`
`Fujitsu and Binstead were cited during the original prosecution of the ’902
`
`patent, but not applied or discussed in any prior art rejection. Honeywell, and
`
`Seguine were not cited during the original prosecution of the ’902 patent. Although
`
`the ’902 patent specification identified Miller (see Ex. 1001, 2:24-28), the
`
`examiner never applied Miller in any prior art rejection during prosecution of the
`
`
`
`9
`
`

`

`
`’902 patent. Fujitsu, Binstead, Honeywell, Miller, and Seguine provide technical
`
`U.S. Patent No. 8,217,902
`Petition for Inter Partes Review
`
`disclosures that the Office believed to be absent in the prior art and are therefore
`
`not cumulative of the art considered by the Office during original prosecution.
`
`The examiner cited and applied Bolender as prior art during the prosecution
`
`of the ’902 patent, but never presented Bolender in combination with the prior art
`
`cited in this Request. Therefore, Bolender is presented in a new light in this
`
`Petition because its materiality, in combination with the prior art cited in this
`
`Petition, was never fully addressed during the prosecution of the ’902 patent.
`
`Claims 1-68 of the ’902 patent include method claims (claims 32-45, 58-68)
`
`and conductor pattern structure claims (claims 1-31, 46-57). Many of these claims
`
`recite substantially the same features (e.g., first and second axis conductor cells,
`
`first and second axis conduction lines, etc.). Accordingly, where appropriate,
`
`Petitioner addresses the claims in groups that share similar limitations or refers to
`
`the analysis of claim limitations found in other claims. Ex. 1013, ¶ 25.
