Desktop Metal, Burlington, Massachussetts, USA, has filed a patent infringement lawsuit in the United States District Court for the District of Massachusetts against Additive Manufacturing company Markforged, Cambridge, Massachusetts, USA.
The lawsuit alleges that Markforged’s Metal X Additive Manufacturing system violates two Desktop Metal patents related to interface layer and separable support strategies for the AM of metal components, and also alleges trade secret misappropriation.
The lawsuit is based on U.S. Patent Nos. 9,815,118 and 9,833,839, which were granted to Desktop Metal in 2017 and cover the company’s interface layer technology for both its Studio System™ and Production System™.
The technology makes it possible to print support structures that do not bond to parts and consolidate during sintering, as well as assemblies that do not consolidate during sintering.
