Platform Specialty Announces Favorable Decision In Patent Dispute With DuPont

(RTTNews) - Platform Specialty Products Corp. (PAH), a specialty chemicals company, Monday said the United States District Court for the District of New Jersey handed MacDermid Inc., a Platform Specialty Products Company, a significant victory in its long fought patent litigation with DuPont.

The court issued summary judgment rulings in favor of MacDermid finding DuPont's U.S. Patent No. 6,773,859 invalid and U.S. Patent No. 6,171,758 not infringed.

These rulings summarily find against DuPont on all of the patent claims asserted by DuPont in this lawsuit.

The ruling, however, leaves all counterclaims made by MacDermid against DuPont in place, in this matter, as well as MacDermid's claims in a related case that DuPont infringed MacDermid's US Patent No. RE39,835.

This ruling follows a related and significant victory by MacDermid in the case of MacDermid v. Cortron Corp. In that case, a Connecticut jury found that DuPont and Cortron colluded against MacDermid to unreasonably restrain trade in violation of U.S. antitrust laws, and awarded MacDermid millions of dollars in damages.
