*This page is intended to serve as notice under 35 U.S.C. § 287(a). Because the list is updated on a periodic basis, it may include patents from a prior update that have since expired or are no longer subsisting. The list may also include patents owned or assigned to third parties who have requested that such patents be associated with certain of Corning’s products. Corning makes no representation with respect to such third party patents including whether such third party patents cover Corning’s products or remain subsisting.
