Federal Circuit holds that Honeywell’s duplication of a previously-invented process does not qualify the company as “another inventor” under 35 U.S.C. § 102(g)(2)

Solvay S.A. v. Honeywell Int’l, Inc., No. 2009-1161 (Fed. Cir. Oct. 13, 2010)
Slip Opinion
The Federal Circuit affirmed-in-part, reversed-in-part, and remanded the U.S. District Court for the District of Delaware, which had invalidated plaintiff Solvay’s patent on a process for making non-ozone-depleting refrigerant gas based on a finding that defendant Honeywell had previously invented the process addressed in five of the patent’s claims. The district court also found that Honeywell had not infringed the patent’s other claims.
In reversing, the Federal Circuit held that Honeywell did not qualify as an “inventor” of the patented process under 35 U.S.C. § 102(g)(2) because the company had merely copied the work of a Russian agency that it had hired to develop the process. The court agreed with Solvay’s argument that Honeywell could not be an “inventor” of the gas manufacturing process because it did not itself invent the subject matter of the process. Writing for the unanimous three-judge panel, Judge Schall emphasized that the originality provision of 35 U.S.C. § 102(f) requires that “the conception of an invention be an original idea of the inventor.” Because Honeywell did not itself conceive of the gas manufacturing process, Honeywell was not a prior inventor of the process and Solvay’s patent on the process is valid.
