Osram Sylvania, Inc. v. American Induction Technologies, Inc.
701 F.3d 698
Fed. Cir.2012Background
- OSRAM appeals district court's grant of summary judgment that claims 1, 17, 25, 27, 32 of the ’905 patent are invalid.
- Representative Claim 1 recites a closed-loop tubular electrodeless lamp with buffer gas pressure <0.5 torr and discharge current ≥2 A.
- Anderson ’334 patent (prior art) allegedly discloses a buffer gas pressure around 1 torr or less and related lamp topology.
- District court found Anderson ’334 anticipated claim 32; other independent claims' invalidity rested on Wharmby with related topologies.
- On appeal, court must decide anticipation, obviousness, and whether district court properly considered objective indicia of nonobviousness.
- Remand instructions require considering secondary considerations and any unresolved factual disputes about prior art combinations.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Did Anderson ’334 anticipate claim 32? | OSRAM argues genus-to-species anticipation; <0.5 torr not necessarily disclosed by 1 torr or less. | AITI argues Anderson ’334 discloses buffer gas range that encompasses <0.5 torr, anticipating claim 32. | Reversed; genuine issues of material fact remain regarding anticipation. |
| Are claims 1, 17, 25, 27 obvious in view of Anderson ’334 and Wharmby? | OSRAM contests that shape irrelevance and that 2 A discharge is an obvious modification with Wharmby. | AITI asserts Wharmby combined with Anderson renders claims obvious. | Reversed; factual disputes about motivation to combine and topology remain. |
| Did the district court properly consider secondary considerations of nonobviousness? | OSRAM provided long-felt need, industry praise, etc.; court failed to consider them. | AITI contends no nexus or adequate tying of secondary considerations to claimed invention. | Remanded to consider secondary considerations before determining obviousness. |
| Was claim 17 improperly decided under obviousness after removal from the motion? | OSRAM argues district court should not have sua sponte rule on claim 17 without notice. | AITI contends removal did not require separate notice for reconsideration. | Not reached; reversed on other grounds; remand governs. |
