dsm-firmenich Announces Successful Defense of Patent Protecting Its Medical-Grade Colored Yarn Products

Exton (Pennsylvania), August 29, 2024

dsm-firmenich announces that the United States Patent and Trademark Office (USPTO) rejected Honeywell’s request for inter partes review (IPR) and cancellation of dsm-firmenich’s U.S. Patent No. 10,280,532, claiming a colored multi-filament yarn.  The protected inventions are useful in medical devices, such as colored Ultra High Molecular Weight Polyethylene (UHMWPE) sutures.

dsm-firmenich, via its subsidiary DSM Biomedical, and Honeywell are currently engaged in a lawsuit in which dsm-firmenich has accused Honeywell’s Spectra® MG Bio Blue fibers of infringing this patent. In the lawsuit, dsm-firmenich is asking the federal court in the District of Delaware (Case # 23-675) to order that Honeywell cease manufacturing, marketing, and selling Spectra® MG Bio Blue fibers in the United States and to award dsm-firmenich financial compensation.

“We are pleased with the USPTO’s decision to uphold our patent,” said Paul Spencer, President of the Biomedical division of dsm-firmenich. “This decision reinforces the strength and validity of our patent and confirms the value of our investments in Ulteeva Purity™ UHMWPE fiber technology.”
