Short Summary
Western Digital requests the PTAB Director to vacate institution of an IPR on a hard‑disk‑drive MTJ patent, arguing that the case should be resolved in the pending district‑court litigation.
Detailed Summary
In a Request for Director Review, Western Digital Technologies, Inc. challenges the Board’s decision to institute IPR2024-01493 covering U.S. Patent No. 10,680,167, which claims a magnetic tunnel junction device used in hard‑disk‑drive technology. Patent Owner contends that proceeding with a piecemeal PTAB review of this single patent, while related patents are already being litigated in the Northern District of California, undermines the AIA’s goal of providing a single, efficient forum. Citing prior denials of related IPRs, differing evidentiary standards between the PTAB and the court, and case law on the inefficiency of fragmented review, the petitioner asks the Director to vacate the institution so the entire dispute can be resolved in federal court.
Practitioner Note
