MacOm Technology Solutions Holdings, Inc. v. Infineon Technologies AG
881 F.3d 1323
Fed. Cir.2018Background
- Nitronex (now MACOM) sold GaN patents to IR (now Infineon) and received a license back covering GaN-on-silicon (GaN-on‑Si) within a defined "Field of Use," plus an "Exclusive Field" where MACOM had exclusivity.
- MACOM developed and sold products using GaN-on‑silicon‑carbide (GaN-on‑SiC), outside the licensed Field of Use; Infineon asserted this was a material breach and terminated the Agreement on March 22, 2016.
- MACOM sued for wrongful termination and declaratory judgment (including noninfringement), and moved for a preliminary injunction declaring the termination ineffective and ordering Infineon to comply with the Agreement.
- The district court granted a preliminary injunction keeping the Agreement in effect, enjoining Infineon from certain activities in MACOM’s Exclusive Field and requiring notice to affiliates and relevant third parties; Infineon appealed.
- The Federal Circuit reviewed (applying Ninth Circuit standards for preliminary injunctions) and considered likelihood of success on the wrongful‑termination claim, irreparable harm, and the injunction’s content and specificity under Fed. R. Civ. P. 65(d).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Likelihood of success on wrongful‑termination claim | MACOM: Termination was wrongful because its GaN‑on‑SiC activity did not breach the Agreement or its implied covenant of good faith and fair dealing. | Infineon: MACOM’s GaN‑on‑SiC activity materially breached the Agreement (violating the implied covenant), justifying termination. | Court: Affirmed that MACOM likely can show no contractual breach of the implied covenant on the record; likelihood‑of‑success finding not erroneous. |
| Irreparable harm | MACOM: Loss of exclusivity and customer perceptions will cause irreparable competitive injury and lost market opportunities. | Infineon: MACOM failed to show harm causally tied to wrongful termination because marketed products may be non‑infringing design‑arounds. | Court: District court’s findings of irreparable harm (including customer perception loss tied to loss of exclusivity) not clearly erroneous; causal nexus sufficient. |
| Scope and specificity of injunction (prohibition of practicing Licensed Patents in Exclusive Field) | MACOM: Contractual relief is appropriate to preserve Agreement and exclusivity; injunction may restrain patent‑related acts consistent with contract. | Infineon: Injunction improperly prohibits future patent‑related acts without identifying specific adjudicated infringing products; violates Rule 65(d). | Court: Vacated that sentence—an injunction forbidding patent infringement without identifying specific adjudicated products fails Rule 65(d). |
| Injunction ordering license‑grant prohibition and notice to third parties | MACOM: Prohibition on sublicensing and notice requirement were proper to protect exclusivity. | Infineon: Second sentence improperly orders specific performance (sublicense ban) without breach; Rule 65(d) concerns for notice paragraph. | Court: Vacated the sentence banning license/sublicenses as improper specific performance absent breach; upheld the notice paragraph and the clarifying sentence permitting GaN‑on‑SiC activity. |
