Background
Satius Holding, Inc. appealed from decisions of the Patent Trial and Appeal Board in an ex parte reexamination of U.S. Patent No. 6,711,385. The Board had rejected claim 1 on obviousness grounds and denied Satius’s request for rehearing.
In a separate case decided the same day, Satius Holding, LLC v. Samsung Electronics Co., No. 2025-1446, the Federal Circuit concluded that claim 1 of the ’385 patent was invalid.
The Court’s Holding
The Federal Circuit dismissed the reexamination appeal as moot. Because the court had already determined in the separate Samsung appeal that claim 1 was invalid, there was no remaining live controversy over the Board’s rejection of that claim.
The court therefore did not reach the merits of the Board’s obviousness determination or its denial of rehearing. It ordered that each side bear its own costs.
Key Takeaways
- A separate judgment invalidating the only patent claim at issue can moot an appeal from a PTAB reexamination decision concerning that claim.
- The Federal Circuit did not review the merits of the Board’s obviousness analysis.
- The disposition is nonprecedential, and the court awarded no costs.
Why It Matters
The decision illustrates how parallel patent litigation can eliminate the live controversy in an administrative patent appeal. Once the Federal Circuit held claim 1 invalid in the related Samsung case, adjudicating the Board’s separate rejection of the same claim could no longer provide meaningful relief.
