The Verdict & Legal Analysis
Outcome
The Federal Circuit dismissed Case No. 25-1981 on February 10, 2026, pursuant to Federal Rule of Appellate Procedure 42(b), which governs voluntary dismissals on stipulation of the parties. The order specified that each side shall bear its own costs — a standard allocation in agreed dismissals that avoids the fee-shifting implications of a contested ruling.
No damages were awarded. No injunctive relief was issued. The dismissal is non-precedential on the merits.
Key Legal Issues
The case was predicated on patentability — specifically an invalidity or cancellation action targeting U.S. Patent No. 8,529,321 B2. This framing suggests Provisur challenged the validity of Weber’s fat cover measurement patent, likely through PTAB proceedings, with Weber subsequently appealing an adverse determination to the Federal Circuit. The voluntary dismissal means the Federal Circuit never adjudicated the merits of the invalidity challenge under Rule 42(b).
