In this installment of the PTAB Highlights, Banner Witcoff examines recent decisions at the PTAB featuring: Patent Owner’s burden to establish priority to foreign application, expert qualifications, how licensing impacts obviousness, and more!
Better put your money (and a translation) where your mouth is when foreign priority is important. Apple Inc. v. Scramoge Technology Ltd., IPR2022-00351, Paper 32 (July 27, 2023) (Wormmeester, joined by Lee and Easthom) (relying on foreign priority application, Patent Owner bore burden to show—with a translation—how a challenged claim was supported by the foreign application to predate prior art reference).
Experts don’t necessarily need to be time travelers. Extractiontek Sales LLC v. Gene Pool Technologies, Inc., IPR2022-00625, Paper 39 (July 26, 2023) (Hardman, joined by Fredman and Wisz) (experience qualifying an expert in the art can be acquired after the effective filing date of a challenged patent).
It’s not a license to drive away from an IPR! Apple Inc. v. Billjco LLC, IPR2022-00427, Paper 41 (July 18, 2023) (Dang, joined by Browne and Baer) (mere existence of licenses to challenged patent could not, without showing nexus to the invention, overcome a convincing case of obviousness).
Don’t just look at the pictures. Skywalker Holdings, LLC v. Board & Batten Int’l Inc., IPR2023-00350, Paper 10 (July 18, 2023) (Murphy, joined by Saindon and Cherry) (even though the examiner considered a reference during prosecution, the Office erred by overlooking non-illustrated embodiments described in the reference; IPR instituted based on the reference).
Mentioning a reference isn’t enough to avoid IPR. Oracle Corp. v. Parking World Wide LLC, IPR2023-00385, Paper 8 (July 19, 2023) (Wood, joined by Saindon and Silverman) (patent not insulated from IPR based on a reference just because the patent specification mentions the reference).
Enough is enough! T-Mobile USA, INC., v. VoIP-Pal.com, Inc., IPR2023-00638, IPR2023-00639, IPR2023-00640, IPR2023-00641, Paper 11 (July 28, 2023) (Weatherly, joined by McMillin and Ogden) (denying institution of a second petition because the Petitioner already used the Board’s finite resources in connection with its first set of petitions and the Board agreed that “enough is enough!”).
