699 F.3d 1317
Fed. Cir.2012Background
- Norgren appeals ITC’s ruling that SMC devices infringing the '392 patent would not violate §337 due to obviousness under 35 U.S.C. §103.
- The '392 patent discloses a four-sided, generally rectangular clamp for joining two fluid-flow elements in FRL/pneumatic systems.
- Independent claim 1 covers a four‑sided, generally rectangular clamp with a hinged side and sealing and locking features.
- On remand, the ALJ found the claims not invalid; the Commission reversed, finding the claims obvious and thus no §337 violation.
- The court reviews the Commission’s obviousness decision de novo and its factual findings for substantial evidence; the Commission relied on prior art old-style SMC connector and Palatchy patent to support obviousness.
- Norgren challenges the old-style SMC connector as not four-sided and not generally rectangular; the Commission accepted testimony deeming it four-sided and rectangular and relied on common-sense hinge modification as obvious.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is the old-style SMC connector four-sided and generally rectangular? | Norgren: old-style SMC not four-sided/rectangular; four-sided requirement not met. | SMC: old-style connector is four-sided and rectangular; supports four-sidedness. | Substantial evidence supports four-sided, generally rectangular characterization. |
| Would adding a hinged side to the old-style SMC connector be obvious? | Norgren: no MOTIVATION to combine; hinge not obvious. | SMC: hinge addition solves loose-parts problem; common-sense solution. | Yes, obvious in light of prior art and common sense. |
| Does the presence of secondary considerations negate obviousness? | Norgren: secondary considerations show nonobviousness. | Commission found secondary considerations insufficient. | Secondary considerations do not overcome the obviousness finding. |
| What is the proper standard of review for the Commission’s findings? | Norgren: ALJ findings should be upheld absent clear error. | Commission reviews ALJ de novo; may revisit remand record. | Court reviews de novo for obviousness; substantial-evidence standard for Factual findings. |
| Are the dependent claims preserved if independent claim 1 is obvious? | Not argued on appeal; decision stands on independent claim obviousness. |
