Narrative Opinion Summary
This case involves a patent infringement dispute between Union Carbide Chemicals and Plastics Technology Corporation, along with Union Carbide Corporation, and Shell Oil Company, Shell Chemical Company, and CRI Catalyst Company. The primary issue is the infringement of claim 4 of Union Carbide's U.S. Patent No. 4,916,243, which covers a process using improved catalysts for ethylene oxide production. Initially, a district court jury found in favor of Union Carbide, confirming Shell's infringement. However, the appellate court vacated the damages awarded due to the improper exclusion of Shell's catalyst exportation from the calculation, and remanded the case for a revised assessment. The court also addressed Shell's appeal regarding the denial of its Judgment as a Matter of Law (JMOL) motions, ultimately affirming the sufficiency of evidence supporting the jury's verdict. In a cross-appeal, Union Carbide challenged the applicability of 35 U.S.C. § 271(f) to process claims, which the appellate court agreed warranted further review on remand. The appellate court upheld the jury's finding of non-willful infringement and concluded that the district court erred in excluding exportation evidence from the damages calculation, necessitating a remand for reassessment. The decision is affirmed in part, reversed in part, vacated in part, and remanded, with each party bearing its own costs.

Application: The appellate court upheld the jury's finding of patent infringement due to substantial evidence presented by Union Carbide, specifically regarding Shell's catalysts' alignment with the limitations of claim 4 of the ’243 patent.
Reasoning: The appellate court affirmed the jury's finding due to substantial evidence supporting it.
Willful Infringement and Evidence of Intentsubscribe to see similar legal issues
Application: The court upheld the jury's finding of non-willful infringement, concluding that Shell's conduct did not reach the threshold of egregiousness required for a willfulness determination.
Reasoning: The court finds that this interpretation overstates the facts, citing prior rulings that do not infer negative implications from the absence of a formal opinion of counsel after awareness of a patent.
