On February 9th, Arkema and Honeywell jointly agreed to dismiss all pending claims and counterclaims about one specific item in their ongoing legal battle over patents relative to HFO-1234yf.
In June of 2010 Arkema, Inc. and Arkema France filed suit against Honeywell International, Inc. in United States District Court. Honeywell countersued to prevent Arkema from producing the chemical.
Arkema asked the federal court to declare Honeywell’s U.S. patents on the chemical invalid because similar work was disclosed and patented earlier in Japan and Russia. The patents in question are 7,534,366 (2009) and 7,279,451 (2007), referred to respectively as the “366” and “451” patents.
In the recent agreement, accepted by both companies and the court, the parties agreed to step back from the ‘451 patent dispute because that patent is now under review by the U.S. Patent and Trademark Office.
Judge William H. Yohn, Jr, noted that “it is not currently known what the scope will be of the claims of the ‘451 patent that issue following the reexamination.”
The court document makes no mention of the ‘361 patent, so the remaining portions of the case continue. A trial date is set for June of this year.
Many believe that this dispute is one roadblock to production of the new refrigerant and its supply to the European market which requires its use in new vehicles.
