Corning Files Eight Inter Partes Review Requests, Week of November 12, 2012

Scott Daniels and Cindy Chen | November 19, 2012

Corning Inc. instantly became the new league leader in the number of inter partes review requests, when it filed against eight DSM IP Assets B.V. last week (see inter partes review Request Nos. (1) to (7)).  Each DSM patent relates to curable coating compositions for optic fibers.  It is not yet clear whether there is litigation between the companies, and as late as last year, Corning and DSM appeared to be partners, announcing a “more than 30 year supply relationship and track record [between the companies] in providing telecom operators with world-leading optical fiber products.”

An as yet undisclosed party requested reexamination of U.S. Patent No. 5,641,805 for ophthalmic compositions (see ex parte Request No. (2)).  The ‘805 patent was the subject of a CAFC decision last year and is owned by Kyowa and Alcon.
