Narrative Opinion Summary
The case involves a patent dispute between Solvay, S.A. and Honeywell International Inc. over the '817 patent related to the production of HFC-245fa. Solvay accused Honeywell of patent infringement, while both parties sought summary judgment on infringement and validity issues. Initially, the court ruled the patent invalid due to anticipation and declared Honeywell the first inventor under 35 U.S.C. § 102(g). The Federal Circuit reversed the invalidity finding but upheld the infringement decision. Following a jury trial, claim 1 of the '817 patent was found invalid due to anticipation by the '192 patent and obviousness. Solvay's post-trial motions for judgment as a matter of law and a new trial were denied, as substantial evidence supported the jury's verdict. The court also upheld its jury instructions and exclusion of certain evidence under Rule 403. The ruling emphasized the importance of clear and convincing evidence in challenging patent validity and the role of expert testimony in determining issues of anticipation and obviousness.
