Watertown, Mass. – July 6, 2021. On July 1, 2021, MarkForged, Inc. (“Markforged”) received a letter from Continuous Composites, a company based in Idaho, containing a notice of purported infringement of four of its U.S. patents, all relating to continuous fiber materials.  Based on Markforged’s and its outside counsel’s review to date of Continuous Composite’s claims, Markforged believes that its Continuous Fiber Composite 3D Printers do not practice the claims of these four related patents.  While Markforged takes any claims of infringement seriously, Markforged believes that Continuous Composite’s claims are baseless and without merit. Continuous Composites may choose to pursue its claims in court or otherwise. If Continuous Composites chooses to pursue its claims, Markforged will vigorously defend against them and pursue all other remedies available against Continuous Composites and its patents.
