Phillips grants import licenses to European plastics firms.
Phillips granted the licenses under its U.S. patent no. 4,376,851.
Under terms of these agreements, Phillips has given Hoechst Aktiengesellschaft, Borealis A/S, Huls Aktiengesellschaft and Vestolen GmbH, and purchasers and subsequent owners of polypropylene produced by these companies in Europe, the right to import into the United States polypropylene homopolymer, random copolymer and block copolymer, as well as finished and semi-finished materials fabricated from these polymers. The Borealis A/S license also applies to polypropylene produced by its predecessor companies, Statoil and Neste Oy.
Monetary terms of the agreements were not disclosed.
Hoeschst Aktiengesellschaft, Borealis A/S, Huls Aktiengesellschaft and Vestolen GmbH join DSM Polymers, Exxon Chemical, BASF Aktiengesellschaft, Tiszai Vegyi Kombinat, Fina Research, PCD Polymere and Himont Italia S.p.A. as the only European polypropylene producers to obtain U.S. import rights for their customers.
Polypropylene purchased from any other European producer is not licensed for import into the United States, whether in the form of polymer or as finished or semi-finished goods. Phillips said it considers any such import by non-licensees to be an infringement of its U.S. patent.
Polypropylene is used to make a wide variety of consumer products: Carpet and upholstery fibers, films for use as food packaging, automotive and appliance parts, medical containers, housewares and various kinds of bottle caps.
Phillips researchers discovered the tough, heat-resistant plastic in 1951 and pioneered its development and use.
