Ge Lighting Solutions, LLC v. Lights of America, Inc.
663 F. App'x 938
Fed. Cir.2016Background
- GE Lighting sued multiple defendants for infringing two LED heat-dissipation patents: U.S. Pat. Nos. 6,787,999 (the ’999 patent) and 6,799,864 (the ’864 patent).
- The litigation involved consolidated cases from the Northern District of Ohio (GE Lighting I and GE Lighting II) with claim construction disputes and summary judgment briefing on indefiniteness.
- The district courts held the asserted claims of the ’864 patent indefinite based on the term “elongated,” and also held the asserted claims of the ’999 patent indefinite based on the phrase “to heat sink.”
- The Federal Circuit reviewed indefiniteness de novo under Nautilus and related precedent, treating intrinsic evidence as primary and extrinsic evidence under a clear-error standard for factual findings.
- The Federal Circuit affirmed that the asserted ’864 claims are indefinite because the patent and prosecution history give no objective boundary for the term “elongated.”
- The Federal Circuit reversed as to the asserted ’999 claims, finding “to heat sink” is an objectively determinable fact (heat transfer either occurs or does not) and therefore not indefinite.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the term “elongated” in asserted claims of the ’864 patent renders claims indefinite | GE: “Elongated” is a plain term and provides sufficient context when read with the specification and prosecution history | Defendants: “Elongated” is a term of degree lacking objective boundaries; skilled artisans cannot determine scope | Held: Indefinite — prosecution history/specification provide no objective boundary; skilled artisan cannot distinguish “elongated” from non-elongated cores |
| Whether the phrase “to heat sink” in asserted claims of the ’999 patent renders claims indefinite | GE: “To heat sink” is indefinite because it lacks a quantified threshold for heat transfer | Defendants: Any transfer of heat suffices; whether heat transfer occurs is an objective question | Held: Not indefinite — ‘‘to heat sink’’ is an objectively determinable fact (heat transfer present or absent); no zone of uncertainty |
