In Harbor Island Dynamic LLC v. Samsung Electronics Co., Ltd., No. 2026-1670 (Fed. Cir. Sep. 15, 2026), the court dismissed the appeal by agreement under Fed. R. App. P. 42(b). The appeal arose from the Board proceeding IPR2024-01403. The order is nonprecedential. Each side bears its own costs. The mandate issued September 15, 2026.
What a Rule 42(b) dismissal is
A Rule 42(b) dismissal ends the appeal because the parties agreed to stop. It is not a written opinion on patentability, claim construction, or the Board's final written decision. The PTAB result in IPR2024-01403 is not re-opened by this Federal Circuit order.
