Exxon, Dow Chemical, And Univation Reach Settlement In Metallocene Dispute

Exxon Corp. (Irving, TX), The Dow Chemical Co. (Midland, MI), and Univation Technologies (Houston) have settled various intellectual property disputes between the companies and their affiliates that relate to metallocene technology. Metallocene is used to produce all forms of polyolefin plastics, including polyethylene and polypropylene.

The confidential agreement settles litigation and other disputes between Exxon and Dow in the US, Germany, Holland, and the UK, as well as between Univation and Dow in the US. The agreement includes alternatives to litigation for resolution of future patent disputes, and the licensing of certain patent rights. Exxon, Dow, and Univation can extend these rights to their customers.

Metallocene catalysts are used primarily to manufacture plastics and rubber. They are classified as "smart" catalysts since, through better manufacturing control, they provide products with improved end-use performance. Plastics made from metallocene catalysts are stronger, purer, and clearer. Metallocene applications include automotive parts, diaper components, refuse and shopping bags, industrial film, heavy-duty shipping sacks, electronic parts packaging, molded containers, and flexible food packages.

Exxon Corp. subsidiary Exxon Chemical Co. (Houston) is a petrochemical producer whose products range from plasticizers for polyvinyl chloride to polymers for wire and cable.

Dow Chemical uses Insite Technology to manufacture Affinity polyolefin plastomers, Elite enhanced polyethylene resins, and Index Interpolymers.

Univation Technologies is a technology and licensing joint venture between Exxon Chemical and Union Carbide. Exxpol metallocene catalyst and technologies are fundamental components of the company's licensing package.
