`
`Petition for Inter Partes Review of USP 10,965,512
`
`
`INTRODUCTION
`Ford Motor Company (“Ford” or “Petitioner”) petitions for inter partes
`
`review of claims 1-30 of U.S. Patent No. 10,965,512 to Li et al. (“the ʼ512
`
`patent”), titled “Method and apparatus using cell-specific and common pilot
`
`subcarriers in multi-carrier, multi cell wireless communication networks.”
`
`The ’512 patent claims techniques for communicating two types of pilot
`
`signals within wireless systems. The ’512 patent admits it was known to use pilot
`
`signals to perform “many important system functions.” EX1001, 1:36-43. The ’512
`
`patent’s only purported advancement was to use two types of pilot signals to
`
`perform such system functions. E.g., Id., 3:10-36. But the claimed features were
`
`well-known and disclosed in various patents and industry publications prior to the
`
`earliest possible priority date of the ’512 patent. This Petition demonstrates that
`
`each challenged claim is not patentable based on a small subset of these patents
`
`and publications, and is supported by Dr. Todor Cooklev. See EX1035, Cooklev
`
`Declaration.
`
`For instance, the primary references presented herein include International
`
`Patent Publication No. WO2004/049618 to Kim et al. (“Kim”), which discloses
`
`orthogonal frequency division multiple access (OFDMA) downlink signals that
`
`include a “[pilot] pattern in common for each cell,” and a different pilot pattern
`
`that is “different for each cell.” EX1004, Kim, 6:23-7:10, 24:20-25:5. The prior art
`
`
`
`- 1 -
`
`

`

`Petition for Inter Partes Review of USP 10,965,512
`
`
`presented herein further includes U.S. Patent Application Pub. No. 2004/0179627
`
`to Ketchum et al. (“Ketchum”), which discloses cellular downlink signals that
`
`include “various types of pilot[s].” EX1006, Ketchum, ¶11-13.
`
`Kim and Ketchum used in various combinations teach the limitations in the
`
`challenged claims of the ’512 patent. Unfortunately however, neither Kim nor
`
`Ketchum—nor any of the other prior-art references relied on herein—were
`
`previously before the Office. If they had been, the ’512 patent would not have been
`
`allowed. Accordingly, the Board should institute this proceeding and find claims
`
`1-30 of the ’512 patent unpatentable.
`
`At present, and not including Petitioner’s IPR, two IPRs have been filed
`
`challenging the ’512 patent: IPR2022-01539 filed by Volkswagen (“Volkswagen
`
`IPR”) and IPR2023-00079 filed by Mercedes (“Mercedes IPR”). See Conditional
`
`Motion for Joinder (filed concurrently). The Volkswagen IPR was filed first and
`
`Mercedes filed thereafter. Id. Petitioner seeks to join the Volkswagen and/or
`
`Mercedes IPRs. Id. Volkswagen refused to share experts for the purposes of this
`
`IPR, which would leave Ford without an expert for cross-examination if
`
`Volkswagen settles out before its expert has been deposed. Id. Accordingly,
`
`Petitioner retained Dr. Todor Cooklev, who prepared a declaration adopting the
`
`opinions set forth in Ex. 1003, the declaration of Dr. Paul Min submitted in
`
`IPR2022-01539, as his own. Petitioner cites Dr. Cooklev’s declaration (Ex. 1035),
`
`
`

`

`
`
`and notes there are corresponding, identical opinions in Dr. Min’s declaration at
`
`the same paragraph numbers (with the exception of the paragraphs discussing the
`
`expert’s qualifications and the like).
`
`Petitioner Ford will rely on Dr. Cooklev’s testimony only if Ford is no
`
`longer in the understudy role due to other parties’ settlement(s) and Patent Owner
`
`has not already deposed Dr. Min or Mercedes’s expert declarant (Mr. McNair), and
`
`the time to do so has not expired. See Conditional Motion for Joinder. All cites
`
`herein to Dr. Cooklev’s declaration (Ex. 1035) should therefore be read as citing
`
`Dr. Min’s declaration (Ex. 1003) unless those circumstances occur.

`
`
`Statutory Grounds for the Challenge
`
`B.
`
`
`
`V. TECHNOLOGY OVERVIEW
`The ’512 patent describes systems and techniques for communicating pilot
`
`signals of different types between base and mobile stations. EX1001, Abstract. The
`
`claims of the ’512 patent recite these systems and techniques in terms of four
`
`general concepts: (i) the system is an orthogonal frequency division multiple
`
`access (OFDMA) system; (ii) base stations communicate various pilots signals to
`
`mobile stations; (iii) mobile stations use the pilot signals for channel estimation
`
`and to recover transmitted data; and (iv) base stations transmit signals using
`
`beamforming. But these concepts and combinations were well-known before the
`
`’512 patent’s earliest possible priority date. EX1035, ¶¶46-63.
`
`A. OFDMA Systems Were Well-Known
`Dr. Cooklev explains that OFDMA systems were well-known prior the ’512
`
`patent. Id., ¶¶47-55. Indeed, orthogonal frequency-division multiplexing (OFDM)
`
`and its “logical extension,” OFDMA, have long been known in the art, including in
`
`cellular systems. EX1015, Anderson, 307; see also EX1035, ¶47.
