AIA Rolls Out New “Virtual” Patent Marking Provision
By Zach W. Hilton
U.S. patent law has long required that patent owners and any licensees mark products they sell with the patent number of any patents covering such products in order to recover pre-suit damages resulting from infringement. Until the passage of the America Invents Act (“AIA”), compliance with the patent marking statute required that a list of patents appear on a covered product itself, although it was sometimes sufficient to mark the product packaging. In either case, compliance with the marking statute led to increased manufacturing costs as it was often necessary to retool product molds and/or redesign packaging as additional patents were deemed to cover a product or as patents expired. The end result was that patent owners were placed at a competitive disadvantage.
