Anthony Inc. v.ControlTec, LLC
ControlTec requests the PTAB Director to overturn the institution of an IPR on its expired ’847 patent, arguing that the patent’s long life creates strong settled expectations and that the cited Carter reference was already deemed non‑material.

Anker Innovations Ltd. v.Powermat Technologies Ltd.
Anker Innovations Ltd. successfully convinced the PTAB to institute an IPR against Powermat Technologies Ltd.'s patent (9083204) covering Inductive Power Transfer technology. The Board found sufficient evidence of anticipation and obviousness over prior art references like Onishi, Purdy, Baarman392, and Tocci.

Bizlink Technology, Inc., et al. v.Ander Power Products, Inc.
The PTAB issued a Final Written Decision finding several claims unpatentable based on anticipation (102) and obviousness (103). The Board adopted specific claim constructions for 'insulating' as 'electrically insulating' and 'within' as 'on the inside of.'
Anker Innovations Limited v.Powermat Technologies Ltd.
Anker Innovations Limited successfully secured institution of its IPR against Powermat Technologies Ltd.'s patent (9048696) based on obviousness grounds. The Board found that the combination of prior art references, specifically Onishi and Flowerdew, provided a reasonable likelihood of prevailing for key claims in Inductive Power Transfer technology.
Anker Innovations Limited v.Powermat Technologies Ltd.
The PTAB issued a Final Written Decision finding that claims 1–7 and 9–14 were unpatentable over prior art references. The petitioner successfully demonstrated obviousness under 35 U.S.C. § 103, particularly regarding the combination of Onishi and Flowerdew for independent claim 1.
Vicor Corporation v.Delta Electronics, Inc.

Vicor Corporation v.Delta Electronics, Inc.
Vicor Corporation challenged Delta Electronics' '263 Patent in an IPR petition, asserting that claims 1-6 are anticipated (102) and obvious (103). The petitioner relies heavily on multiple combinations of prior art references, including Vinciarelli and Zeng patents, to demonstrate unpatentability.
LEDUP MANUFACTURING GROUP LTD. v.Seasonal Specialties, LLC
The Petitioner successfully demonstrated anticipation and obviousness for the majority of claims (1, 2, 4–7, 9–14) related to a resistor bypass circuit for LEDs. The Board found that prior art references disclosed all limitations or provided clear motivation for substitution in multiple instances.
