`U.S. Patent No. 7,864,503
`Petition for Inter Partes Review
`
`I.
`
`Introduction
`
`Digital Empire Limited (“Petitioner”) requests inter partes review of all claims
`
`1-12 of U.S. Patent No. 7,864,503 (“the ’503 patent”) (Ex. 1001) assigned on its
`
`face to Hilltop Technology LLC (“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 ’503 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 ’503 patent. Claims 1-12 of
`
`the ’503 patent should be found unpatentable and canceled.
`
`II. Mandatory Notices Under 37 C.F.R. § 42.8
`
`Real Party-In-Interest: Digital Empire Limited is the real party-in-interest.
`
`Related Matters: Patent Owner has asserted the ’503 patent against several
`
`defendants in patent infringement litigation filed in the Eastern District of
`
`Texas. The litigation remains pending. To the Petitioner’s knowledge, the ’503
`
`patent has not been subject to any post grant review or any prior inter partes
`
`review.

`VI. Overview of the ’503 patent
`
`U.S. Patent No. 7,864,503
`Petition for Inter Partes Review
`
`The ’503 patent issued from U.S. Application No. 12/148,998 (“the ’998
`
`application”) and is directed to a “capacitive type touch panel”. (Ex. 1001,
`
`Abstract). The ‘503 patent purports to eliminate the difficulty in identifying the
`
`location touched by the user. (Id. At 1:46-471).
`
`FIG. 2 of the ’503 patent discloses a capacitive type touch panel, which includes
`
`transparent substrate 3 having opposite top and bottom surfaces 31, 32; an array
`
`of first conductors 41 formed on the top surface 31 of the transparent substrate 3;
`
`an array of second conductors 42 formed on the top surface 31 of transparent
`
`substrate 3 and disposed alternately with first conductors 41; a plurality of
`
`spaced apart conductive first bridging lines 412, each of which interconnects two
`
`adjacent ones of first conductors 41;a plurality of spaced apart conductive second
`
`bridging lines 422, each of which interconnects two adjacent ones of the second
`
`conductors 42 and each of which intersects insulatively a respective one of first
`
`bridging lines 412; and a plurality of spaced apart insulators 5, each of which is
`
`disposed at an intersection of a respective one of the first bridging lines 412 and
`
`the respective one of the second bridging lines 422 so as to separate the

`respective one of the first bridging lines 412 from the respective one of the
`
`second bridging lines 422. The first and second conductors 41, 42 and the first
`
`and second bridging lines 412, 422 cooperatively form into a matrix of capacitive
`
`regions when a current is applied to the first and second conductors 41, 42 and
`
`the first and second bridging lines 412, 422. See Id. at 2:28-52.

`
`’503 patent further discloses that each of “the first and second conductors 41, 42
`
`is formed with a plurality of holes 413, 423, and more preferably, each of the
`
`holes 413, 423 is a through-hole”. Since the area of each of the first and second
`
`conductors 41, 42 is a key parameter to the capacitance, sensitivity in detecting
`
`the coordinates of a touched location by the user can be adjusted through
`
`changing of the number and/or the diameter of the holes 413, 423. Id. 2:58-65.

`
`issue fee and the patent was granted.

`Petition for Inter Partes Review
`
`C.F.R. § 42.100(b).
`
`Petitioner submits that the following terms should be construed in the manner
`
`set forth below: (1) “transparent substrate;” (2) “plurality of holes;” and (3)
`
`“through-hole.” For all remaining terms, Petitioner submits, for the purposes of
`
`this inter partes review only, that the claim terms take on their ordinary and
`
`customary meaning that the terms would have to one of ordinary skill in the art.
`
`Petitioner submits that none of the challenged claims contain a means-plus-
`
`function or step-plus-function limitation.
`
`(1)
`
` “transparent substrate” (claims 1-12)
`
`Applying the broadest reasonable construction, consistent with the specification,
`
`the term “transparent substrate” as used in claims 1-12 of the ‘503 patent
`
`includes a substrate with a transmittance of less than 100 percent. The amount
`
`of transparency of a substrate is determined by its transmittance, and
`
`transmittance is defined as the amount of light that travels through the substrate.
`
`The amount of light transmitted through the substrate is determined by 1) the
`
`substrate’s thickness, 2) the wavelength of the incident light on the substrate,
`
`and 3) the refractive index of the material that is used to build the substrate. (Ex.

`h/references/glass/Schott/tie-35_transmittance_us.pdf ). The ‘503 specification
`
`does not provide the details of the thickness of the substrate nor the wavelength
`
`of the light. The materials described in the ‘503 specification have a wide range
`
`of refractive indexes, thus generating substrates with differing levels of
`
`transmittance and varying degrees of transparency. Therefore, applying the
`
`broadest reasonable construction, the term “transparent substrate” should be
`
`construed as a substrate that has different levels of transparency; including the
`
`term “substantially transparent substrate”. Ex. 1018, ¶ 21.
`
`(2)
`
`“plurality of holes” (claim 5)
`
`Applying the broadest reasonable construction, consistent with the specification,
`
`the term “plurality of holes” as used in claims 5-8 of the ’503 patent means that
`
`holes are made on the conductive material and once the hole is made no
`
`material exists on the conductive material where the holes are located. Ex. 1018,
`
`¶ 22.
`
`(3)
`
`“through hole” (claims 6)
`
`Applying the broadest reasonable construction, consistent with the specification,
`
`the term “plurality of holes” as used in claims 5-8 of the ’503 patent means that
`
`holes are made on the conductive material such that no conductive material
`
`exists in the area where the hole is made.(no holes are made on the transparent

` IX. Detailed Explanation of Grounds for Unpatentability Under the
`
`Broadest Reasonable Construction
`
`Lai was cited during the original prosecution of the ’503 patent, but not applied
`
`or discussed in any prior art rejection. Binstead, Fujitsu, Bolender , Seguine, Fong,
`
`Aoki, Jain, Ohtake, Takeda, Chen, Nakanishi-1, and Nakanishi-2 were not cited
`
`during the original prosecution of the ’503 patent. Binstead, Fujitsu, Bolender ,
`
`Seguine, Fong, Aoki, Jain, Ohtake, Takeda, Chen, Nakanishi-1, and Nakanishi-2
`
`however, provide technical disclosures that the Office believed to be absent in
`
`the prior art and are therefore not cumulative of the art that was considered by
`
`the Office during original prosecution.
`
`The examiner did not cite and apply any of the prior arts Binstead, Fujitsu, Bolender ,
`
`Seguine, Fong, Aoki, Jain, Ohtake, Takeda, Chen, Nakanishi-1, and Nakanishi-2 as
`
`prior art during the prosecution of the ’503 patent. Lai 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 ’503 patent.

`A. Ground 1: Fujitsu Anticipates Claims 1, 2, and 3.

`3. See Fujitsu.
