• Telefonaktiebolaget LM Ericsson / Ericsson Inc. et al. v. K.Mizra LLCNo claims unpatentable
  PTAB · Oct 26, 2023 · IPR2022-00730 · APJ Iftikhar Ahmed · IPR · Final written decision

  Claims 22, 23, 30, 32, and 33 were not shown unpatentable because Pakzad did not disclose the claimed combined macro and femto timing information, and the obviousness grounds did not address that limitation.

  • Expert testimonyPatent owner expert creditedPetitioner expert discountedDecided for patent owner

    “information from all three types of sources together or at the same time. Patent Owner argues that “a [person of ordinary skill in the art] would understand that this passage in Pakzad ‘any one of several sources’ confirms that Pakzad only uses a single signal source at a time.” PO Resp. 34 (citing Ex. 2002 ¶ 69). Dr. Chrissan testifies that he understands this disclosure to mean that “Pakzad teaches a single signal source at a time, not more than one.” Ex. 2002 ¶ 70 (emphasis added). We find Patent Owner’s interpretation, supported by Dr. Chrissan’s testimony, to be a reasonable reading of Pakzad’s disclosure. Dr. Chrissan further testifies that “Pakzad’s invention is about using both a course [sic] routing graph and fine routing graph to make computation of a motion model (e.g., a particle filter) more efficient,” and “Pakzad was not directed to leveraging a heterogenous network by incorporating both macro and femto cells concurrently.” Id. ¶ 68. We agree with Dr. Chrissan’s explanation for the lack of clear disclosure in Pakzad about which measurements Pakzad uses with its particle filter.” slip op. at 25

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 17. Petitioner contends that a person of ordinary skill in the art “would have been someone with at least (1) a bachelor’s degree in electrical engineering, computer engineering/science, or a related scientific field, and (2) either (a) a master’s degree in electrical engineering, computer engineering/science, or a related filed, or (b) two or more years of work or research experience in wireless networking and/or computing.” Pet. 21 (citing Ex. 1009 ¶ 23). Patent Owner does not dispute Petitioner’s definition for a person of ordinary skill in the art, but adds that the person of ordinary skill in the art “may alternatively have additional years of practical and relevant work or research experience as substitution for less or different technical education, and vice versa.” See PO Resp. 17. We determine that the level of ordinary skill proposed by Petitioner is consistent with the ’819 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978). We adopt Petitioner’s proposed level in deciding the patentability of the challenged claims.” slip op. at 9

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “claim 30 should be construed “to refer to the previously recited ‘femto base station timing information,’ ‘macro base station timing information,’ and ‘femto base station position information.’” PO Resp. 18. Patent Owner argues that its proposed construction is “based on at least three aspects of the intrinsic record: (1) the claim language itself; (2) guidance from the specification defining the disputed term; and (3) illustrative embodiments confirming the meaning of the disputed term.” Id. (citing Ex. 2002 ¶ 47). Specifically, Patent Owner contends that “the specification describes two embodiments that further confirm to a [person of ordinary skill in the art] that ‘the base station information’ consists of the [three types of information previously] recited.” Id. at 19–23 (citing Ex. 1001, 19:29–33, 20:50–54, Figs. 8, 9; Ex. 2002 ¶¶ 47–55).” slip op. at 10

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable

    “More importantly, anticipation requires that the four corners of a single, prior art document describe every element of the claimed invention, and we are not persuaded that Pakzad describes the combinational use of the two different types of timing information as claimed. See Xerox Corp. v. 3Com Corp., 458 F.3d 1310, 1322 (Fed. Cir. 2006) (citing Advanced Display Sys., Inc. v. Kent State Univ., 212 F.3d 1272, 1282 (Fed. Cir. 2000)). The Federal Circuit has made it clear that “it is not enough that the prior art reference discloses part of the claimed invention, which an ordinary artisan might supplement to make the whole, or that it includes multiple, distinct teachings that the artisan might somehow combine to achieve the claimed invention.” Net MoneyIN, 545 F.3d at 1371 (citation omitted) (emphasis added). In Net MoneyIN, although a prior art reference described two protocols, which when taken together, disclosed “all five links arranged or combined in the same way as claimed,” the Federal Circuit determined that the reference did not anticipate the claim. See id. Rather, the Federal” slip op. at 28
