In CyWee Group LTD. V. ZTE (USA), Inc., No. 21-1855 (Fed. Cir. 2024), ZTE filed an IPR petition against U.S. Patent No. 8,441,438 (the ’438 patent) owned by CyWee, which the Patent Trial and Appeals Board (“the Board”) instituted. LG later filed a separate IPR petition also challenging the ’438 patent and moved to join ZTE’s IPR. LG acknowledged that its IPR petition was untimely under 35 U.S.C. § 315(b) because CyWee sued LG more than a year before LG filed its petition. LG premised its request for joinder on several limitations, the most relevant of which was that LG would act only as a passive understudy and not assume an active role in the IPR unless ZTE ceased to participate in the instituted IPR.Continue Reading Navigating Revised Motions to Amend in Inter Partes Review as a Non-active, Joined Party

In particular, this case establishes: (1) which party bears the burden of proof regarding whether a “skilled and diligent searcher” could have reasonably been expected to discover prior art such that failure to include it in an IPR petition estops the petitioner from raising it in other civil actions under 35 U.S.C. § 315(e)(2); and (2) the “skilled and diligent searcher” inquiry itself with respect to what a skilled and diligent searcher reasonably would have been expected to discover.Continue Reading Ironburg Inventions Ltd. v. Valve Corp. 21-2296 (Fed. Cir. Apr. 3, 2023)
