Nichia Corporation v. Everlight Americas, Inc.
855 F.3d 1328
Fed. Cir.2017Background
- Nichia, a leading LED manufacturer and patent holder, sued Everlight (an LED packager) for infringement of three patents covering LED package designs and manufacturing methods. The district court found infringement and validity for all asserted claims but denied Nichia a permanent injunction. Nichia appealed; Everlight cross-appealed.
- The asserted patents (’250, ’870, ’589) claim package features and manufacturing steps addressing singulation breakage, thermal-cycle-induced separation, and adhesive overflow in tiny LED packages.
- District court held (after bench trial) that Everlight’s accused products infringed the asserted claims and that Everlight failed to prove invalidity by clear and convincing evidence.
- The district court denied an injunction, finding Nichia failed to show irreparable harm (lack of meaningful competition, no proven lost sales or price erosion, and Nichia’s licensing reduced risk of harm).
- On appeal, the Federal Circuit reviewed factual findings for clear error and legal conclusions de novo, affirmed infringement and validity rulings, and affirmed denial of injunctive relief as within the district court’s discretion.
Issues
| Issue | Nichia’s Argument | Everlight’s Argument | Held |
|---|---|---|---|
| Claim construction of “lead” (’250) | “Lead” means the conductive portion in device (supporting broad construction) | Must require electrical connection to outside structure | Court/Fed. Cir.: "lead" = portion of device that conducts electricity; no external-connection requirement; affirmed infringement |
| Claim construction of “planar” (’250) | Claim term should read in light of spec as "in a substantially same plane" | "Planar" means no measurable surface variation (perfectly flat) | Court/Fed. Cir.: "planar" = "in a substantially same plane"; slight concavities do not avoid infringement; affirmed |
| Obviousness of ’250, ’870, ’589 patents | Patents non-obvious given LED-specific design considerations and lack of motivation to combine references | Prior art (Hitachi, Glenn, Sanyo, Waitl, Nitta, Nakashima, Kim) render claims obvious when combined | Fed. Cir.: factual findings (no disclosure of key claim elements, lack of motivation to combine due to distinct technologies/design constraints) not clearly erroneous; affirmed non-obviousness |
| Permanent injunction denial | Nichia: infringement and market characteristics (design-win, switching costs) warrant injunction; licenses do not preclude irreparable harm | Everlight: lack of meaningful competition, no proven lost sales/price erosion, Nichia’s licensing harms exclusivity — money damages adequate | Fed. Cir.: district court did not abuse discretion; Nichia failed to prove irreparable harm (no meaningful competition, no but-for lost sales, licensing and market realities weigh against injunction); affirmed |
