Case Filed: Sep 14, 2012
Case Closed: Feb 12, 2014
Origin Case: 1:06-cv-00557
Honeywell won a verdict on a patent
asserted by Solvay concerning methods for making refrigeration chemicals, which
was declared invalid.
Solvay sued Honeywell in the United
States District Court of Delaware alleging that the process Honeywell was using
to manufacture HFC-245fa infringed certain claims of the patent. The patent in question was: US6730817,
entitled ‘Method for preparing 1,1,1,3,3-pentafluoropropane’, issued on May 04,2004
and expiring[i] by
Oct 23, 2015. The patent is currently assigned[ii]
to Solvay (source: MaxVal’s Assignment
Database).
The complaint alleged that
Honeywell manufactured halogenated fluorocarbons which it believed to be infringing
and asked court to enjoin infringement. The district court held that asserted
claims of Solvay’s ‘817 patent were invalid. Solvay appealed the judgment of
district court, which was again declared in favor of Honeywell.
Initially, Federal Court ruled that
Honeywell infringed the patent but later ordered further proceedings. After
various discussions and findings it affirmed the district court’s judgment of the
’817 claims as invalid.
