Narrative Opinion Summary
In this case, American Hoist and Derrick Co. (AmHoist) appealed a decision from the U.S. District Court for the District of Oregon, which ruled in favor of Sowa Sons, Inc. (Sowa) on claims of patent infringement concerning a heavy-duty shackle. The jury found all patent claims invalid due to obviousness and fraud during prosecution, leading to an award of attorney's fees to Sowa under 35 U.S.C. § 285. However, the Federal Circuit vacated the jury's findings due to incorrect jury instructions and remanded for a new trial, while also addressing Sowa's counterclaims of antitrust violations. The court underscored errors in instructing the jury on burdens of proof and emphasized the necessity for Sowa to establish a relevant market in its antitrust claims. The PTO had approved AmHoist's reissue application, which complicated the determination of patent validity. Ultimately, the appellate court reversed and remanded several decisions, including the invalidity finding and attorney's fees award, due to procedural and factual disputes requiring further examination.
Legal Issues Addressed

Application: The district court deemed the case 'exceptional' under 35 U.S.C. § 285, warranting an award of attorney's fees to Sowa due to AmHoist's conduct during patent prosecution.
Reasoning: The court deemed the case 'exceptional' under 35 U.S.C. § 285, despite insufficient evidence to support defendant AmHoist's unfair competition claim.
Burden of Proof in Patent Invalidity Claimssubscribe to see similar legal issues
Application: The court identified an error in jury instructions that misallocated the burden of proof, which should remain with the party challenging the patent's validity.
Reasoning: First, it misallocated the burden of proof, contrary to 35 U.S.C. Sec. 282, which asserts that the burden of establishing a patent's invalidity lies with the party claiming invalidity, a principle reinforced by precedent.
Fraud during Patent Prosecutionsubscribe to see similar legal issues
Application: The court found sufficient evidence of fraud during patent prosecution, which contributed to the jury's finding of invalidity and justified the exceptional case status under 35 U.S.C. § 285.
Reasoning: The jury also concluded that AmHoist's patent was invalid and that it had committed fraud on the Patent Office, although a reissue application had been approved.
Patent Obviousness under 35 U.S.C. § 103subscribe to see similar legal issues
Application: The court concluded that the Shahan patent was obvious to a person of ordinary skill in the relevant field at the time of invention, primarily due to its circular cross-section design.
Reasoning: The jury found that the Shahan patent was obvious to a person of ordinary skill in the relevant field at the time of invention, primarily due to its circular cross-section design, which was not novel and had been previously seen in anchor shackles.
