Case Overview
The Parties
⚖️ Plaintiff
North Carolina-based semiconductor company specializing in bulk acoustic wave resonator technology for mobile, 5G, and defense applications.
🛡️ Defendant
Global leader in RF semiconductor solutions, with an extensive IP portfolio covering BAW and surface acoustic wave (SAW) filter technologies.
Patents at Issue
This case involved two semiconductor patents integral to BAW filter technology:
- • US9735755B2 — Covers semiconductor resonator technology relevant to BAW filter design and fabrication.
- • US7522018B2 — An earlier patent addressing foundational bulk acoustic wave device architecture.

The Verdict & Legal Analysis
Outcome
The Federal Circuit dismissed Case No. 25-1250 pursuant to Federal Rule of Appellate Procedure 42(b), which authorizes voluntary dismissal of an appeal upon the parties’ stipulation. The court’s order explicitly directed that each side bear its own costs. No damages award, injunctive relief, or judicial finding on the merits was issued.
Verdict Cause Analysis
The case was designated as an Infringement Action, meaning the original claim centered on Akoustis asserting that Qorvo’s BAW filter products infringed one or both patents-at-issue. The voluntary dismissal with each side bearing its own costs strongly implies a negotiated resolution — potentially including a licensing agreement or commercial settlement — rather than a unilateral capitulation by either party.
