Narrative Opinion Summary
The case involves a patent infringement lawsuit filed by Solvay, S.A. against Honeywell Specialty Materials LLC and Honeywell International Inc., concerning U.S. Patent No. 6,730,817. The patent covers processes for producing the environmentally friendly hydrofluorocarbon HFC-245fa. Solvay claims that Honeywell's Geismar process infringes specific claims of the patent. Both parties filed cross-motions for summary judgment, with Solvay seeking confirmation of infringement and Honeywell arguing for non-infringement. The court, having jurisdiction under 28 U.S.C. § 1338, granted Solvay's motion for summary judgment regarding the infringement of Claim 1, citing that Honeywell's process met the broad construction of the patent claims. Conversely, the court granted Honeywell's motion for non-infringement concerning Claim 12, as the Geismar process failed to satisfy specific limitations of retaining certain compounds in the reactor. The decision upheld Solvay's summary judgment for Claim 1 and Honeywell's for Claim 12, affecting related dependent claims.
