EPC Lawsuit Update: Innoscience Acknowledges U.S. Patent and Trademark Office For Institution Decisions to Review Validity of All EPC’s Asserted Patents: 4 of 4 Patents Instituted at USPTO

07Apr 2024 News

4th April 2024 - Innoscience Technology, a company founded to create a global energy ecosystem based on high-performance, low-cost, gallium-nitride-on-silicon (GaN-on-Si) power solutions, welcomes, with thanks, two additional decisions, from March 26, 2024, by the United States Patent and Trademark Office (USPTO) to institute review of the validity of yet another two (and still additional) U.S. patents of Efficient Power Conversion Corporation (“EPC”).

The two additional U.S. patents, which are now under review at the USPTO, were previously asserted by EPC at the beginning of the legal dispute initiated by EPC in the U.S. International Trade Commission (ITC).  During the course of that proceeding, however, EPC withdrew these patents, but Innoscience maintained its challenges of these patents at the USPTO.

In the March 26, 2024 decisions, the USPTO decided to institute the review of the validity of these two further U.S. patents, as previously asserted by EPC in the ITC proceeding. These new decisions to institute now supplement two other and prior decisions to institute by the USPTO, relating to the other two patents that are still asserted by EPC at the ITC.  Now, in all four decisions, the USPTO has concluded that “there is a reasonable likelihood that Petitioner [Innoscience] would prevail with respect to at least one of the claims challenged in the Petition.”  Innoscience has achieved, via the preliminary decisions, a perfect 4-for-4 record at the USPTO.

Also, now all patents that were asserted by EPC now are under review by the USPTO.  These new March 26, 2024 rulings by the USPTO are only the latest developments related to EPC’s misguided lawsuits against Innoscience, wherein EPC continues to 

struggle in its meritless attacks on Innoscience. In all four rulings now, including from March 20 and March 26, 2024, three judges from the USPTO have initially agreed with Innoscience, that the EPC patents that Innoscience challenged at the USPTO are invalid. And, once again, in this new set, Innoscience again argued to the USPTO that the challenged EPC patent was invalid, based on a prior patent of an EPC cofounder/inventor when he was at International Rectifier, and on a preliminary basis, according to the institution decision, the USPTO agreed with Innoscience. In all four proceedings, Innoscience has described multiple reasons why the four EPC patents are invalid, and for virtually every argument on invalidity, the USPTO initially agreed. Next, the USPTO will receive additional briefing and make final determinations by March 26, 2025.

Innoscience is confident that it will achieve an eventual complete victory in the dispute with EPC. With these recent USPTO decisions of March 26, 2024, Innoscience continues to achieve successes in its legal dispute with EPC, and the additional USPTO decisions repeatedly demonstrate that EPC’s accusations against Innoscience lack merit, given that the USPTO has now determined, at least initially, that all four EPC patents asserted by EPC are likely invalid.
