“single §102 rejection based solely on Nishida.” Pet. § 325(d) Reply 3 (emphasis omitted). Specifically, Petitioner argues that: The examiner seemingly failed to consider how it would have been obvious to combine Nishida (or any other reference of record, such as Orei) with knowledge in the art, including the fact that it was “well known to use double needle-bar raschel machines . . . to knit textile elements simultaneously with surrounding textile structures” (Pet., 37–38), and that simultaneous knitting would be obvious because it would “increase yield and reduce manufacturing steps,” as explained in the Petition and supporting evidence. See Pet., 42–44. Id.

We do not find this argument persuasive. The cited portion of the Petition is the contention that Orei—not Nishida—would render obvious claim 1. See Pet. 37–38, 42–44 (Ground 1A). Thus, Petitioner has not shown persuasively that the Examiner erred in not making an obviousness rejection based on Nishida because the disputed limitation was purportedly well-known. Additionally, Petitioner’s support for the assertion that this limitation is well-known is not persuasive. The Petition parenthetically quotes from a source stating that plural “articles . . . can be simultaneously knitted side-by-side,” not that an article (a textile element) and surrounding textile structure are known to be simultaneously knitted.
