Wellman Sues Eastman Over Polyester

Department: Business

Polyester maker Wellman is suing Eastman Chemical for patent infringement. Wellman says polyethylene terephthalate (PET) resins made with Eastman's new IntegRex technology infringe on Wellman patents covering titanium-catalyzed PET resins. Wellman also claims that preforms—plastic structures that are blown into PET bottles—made with IntegRex-based resins also infringe on its patents. Eastman says it has no comment.
