Short Summary
Stratasys has filed a Request for Director Review to overturn the referral and institution of an IPR covering its 3D‑printing patent. The company argues the PTAB misapplied Fintiv factors and that the parallel district‑court case makes the IPR redundant. It seeks termination of the proceeding under § 314(a).
Detailed Summary
In IPR2025-00532, Stratasys, Inc. challenges the PTAB’s decision to refer and institute inter partes review of claims 1‑15 of U.S. Patent No. 10,556,381, a 3D‑printing technology patent. The Patent Owner contends that the Acting Director failed to give proper weight to Fintiv factors 2 and 3, ignoring the imminent district‑court trial date and the extensive discovery already completed. It further argues that the petitioner’s stipulations do not moot the parallel litigation, allowing duplicate invalidity challenges. Relying on case law and the Guidance Memorandum, Stratasys requests Director Review to vacate the decisions and terminate the IPR under 35 U.S.C. § 314(a).
