Webvention Patent Litigation

MDL 2294 was assigned to the District of Maryland by the Judicial Panel on Multidistrict Litigation on December 15, 2011. The suit involves factual questions about the infringement and validity of U.S. Patent 5,251,294, which relates to basic web presentation technologies, such as previews that appear when a mouse rolls over certain website features. Plaintiff patentholder, Webvention Group, claims defendants have infringed on the patent by incorporating its innovations in their websites. The defendants, some of whom initiated litigation by seeking declaratory judgments, deny infringement and assert that the ‘294 patent is invalid.

The litigation, which consolidates actions initiated in the Eastern District of Texas and the District of Delaware, has been centralized in the District of Maryland before Judge Catherine C. Blake.
