Summary
The United States Court of Appeals for the Federal Circuit affirmed the International Trade Commission’s determination of no violation of section 337 based on its finding that claims 1–5, 7, and 9 of Norgren’s patent were invalid as obvious. The court held that substantial evidence supported the Commission’s findings that the prior-art SMC connector was four-sided and generally rectangular and that adding a hinge would have been obvious. Judge Moore dissented, concluding that the prior-art clamp did not satisfy the claimed four-sided, generally rectangular limitation.

Questions Presented
- Whether substantial evidence supported the Commission's finding that the old-style SMC connector was a four-sided, generally rectangular clamp within the meaning of the patent claims.
- Whether substantial evidence supported the Commission's determination that adding a hinged side to the old-style SMC connector would have been obvious to a person of ordinary skill in the art.
- Whether the Commission's de novo reversal of the ALJ and its different conclusion from an earlier proceeding rendered its decision arbitrary and capricious.
Holdings
- The Commission's finding that the old-style SMC connector was four-sided and generally rectangular was supported by substantial evidence.
- Claims 1-5, 7, and 9 of the '392 patent were invalid as obvious because adding a hinge to the old-style SMC connector would have been an obvious modification for solving known problems of loose parts and ease of use.
- The Commission was entitled to review the ALJ's findings de novo, and its different conclusion after remand was not arbitrary or capricious.

Factual background
Norgren's '392 patent claims a four-sided, generally rectangular hinged clamp for connecting fluid-flow elements in compressed-air systems. SMC marketed or imported devices using an older connector that the Commission found to be a four-sided, generally rectangular clamp, differing from the claimed clamp principally by the absence of a hinge. The Commission found that adding a hinge would have been an obvious solution to known problems involving loose parts and ease of use, and it found the evidence of secondary considerations insufficient to establish nonobviousness.
Procedural history
Norgren filed a section 337 complaint alleging that SMC's imported or sold devices infringed U.S. Patent No. 5,372,392. The ALJ initially found no violation based on a claim construction that required four projecting rims and also found the claims nonobvious. The Federal Circuit reversed the noninfringement determination, vacated the nonobviousness determination, and remanded for consideration under the new claim construction. On remand, the ALJ found the claims nonobvious, but the Commission reversed, found the claims obvious, and determined that there was no section 337 violation. The Federal Circuit affirmed.
