Document:
Yesterday, the Patent Trial & Appeal Board (PTAB) designated two older AIA trial decisions, and one recent decision, precedential. These three decisions follow last week’s Precedential Opinion Panel (POP) decision in Proppant Express Investments v. Oren Technologies, which held issue joinder was embraced by 35 U.S.C. § 315(c), but a matter of Board discretion.
The POP reversed the earlier (divided) panel decision in Proppant Express (which conflicted with the earlier consensus of Target Corp. v. Destination Maternity), holding that 35 U.S.C. § 315(c) permits issue joinder. More specifically, the POP held that 315(c) provides discretion to allow a petitioner to be joined to a proceeding in which it is already a party and provides discretion to allow joinder of new issues into an existing proceeding (here).
Today, the Patent Trial & Appeal Board (PTAB) designated Lectrosonics, Inc. v. Zaxcom, Inc, (IPR2018-01129, 01130, Paper 15 (Feb. 25, 2019) precedential as to the agency’s interpretation of 35 U.S.C § 316(d), amendment requirements and burden.
