“partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” 35 U.S.C. § 315(b) (emphasis added). Accordingly, a petition for inter partes review may be considered only if, among other things, it “identifies all real parties in interest,” and no real party in interest was served with a complaint alleging infringement of the challenged patent more than one year before the petition was filed. 35 U.S.C. § 312(a)(2). “[T]he IPR petitioner bears the burden of persuasion to demonstrate that its petitions are not time-barred under § 315(b) based on a complaint served on a real party in interest more than a year earlier.” Worlds Inc. v.

“Based on the arguments and evidence of record, we determine that Patent Owner has not produced sufficient evidence to support a finding that STMicro should be named a real party in interest to this proceeding. At best, Patent Owner’s evidence and arguments establish only that Patent Owner previously filed a complaint against STMicro, asserting that STMicro infringed patents related to the ’648 patent (see generally Ex. 2012); and that Patent Owner served a subpoena to compel STMicro to testify and produce documents in Patent Owner’s infringement suit against Petitioner (see generally Ex. 2014). The record before us does not demonstrate a relationship between Petitioner and STMicro sufficient to show that STMicro is a real party in interest.

- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner
“We find unavailing Petitioner’s reliance on Catalina to support its claim construction position. See Reply 2. In particular, although Petitioner contends the body of the claims “define[s] a structurally complete invention,” Petitioner does not explain how the claims additionally “use[] the preamble only to state a purpose or intended use for the invention,” as Catalina further requires. See Catalina, 289 F.3d at 808 (“a preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention” (emphasis added)). In this regard, we discern no reason to interpret “[a] micro inertial measurement unit” as reciting only a purpose or intended use because the term, on its face, uses “micro inertial measurement” as an adjective that conveys further structural details of the unit. Accordingly, on the complete record, and for the reasons set forth in our Institution Decision, we maintain our construction that “[a] micro inertial measurement unit” recited in the preamble is limiting and requires a micro-sized inertial measurement unit, and that the structures recited in the limitations of the claims are limited to structures implemented as MEMS devices.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“Record evidence supports Petitioner’s contentions that a skilled artisan would have had reason to look to Kumar for further implementation details of a circuit that performs functions like those performed by Fujiyoshi. See Pet 24–26. For example, Dr. Young testifies that a person of ordinary skill in the art would have recognized that Kumar discloses the details, at a granular level, of Fujiyoshi’s capacitive sensing systems and would have looked to Kumar for understanding of how to implement Fujiyoshi’s system. Ex. 1002 ¶ 145. Patent Owner does not point to persuasive evidence to rebut this opinion. Moreover, Petitioner cites to Kumar, not only for an explicit disclosure of capacitive pickoff signals, but also for its disclosure of both DC bias and AC carrier signals and recognizing the applicability of an AC carrier pickoffs that operates without DC bias. Pet. 24–26 (citing Ex. 1005 3:65–4:2, 6:29–36). We credit Dr. Young’s testimony on this issue and agree with Petitioner that a person of ordinary skill in the art, looking at Fujiyoshi’s description of capacitive sensing systems, would be motivated to look to Kumar for its more detailed teachings of the implementation details of such systems and would combine these details to arrive at limitation 1(a). We determine that Petitioner has shown, by a preponderance of the evidence, that one of ordinary skill in the art would have been motivated to combine Fujiyoshi and Kumar in the manner argued by Petitioner.” slip op. at 37
