The ruling upholds the broadest claims of the patent, reversing previous limitations imposed during earlier proceedings. Carbon’s dual-cure method merges light-based printing with a secondary thermal reaction, allowing for the creation of components with specific engineering-grade properties such as durability and heat resistance. This chemistry serves as a critical component for the firm’s Digital Light Synthesis platform, which supports production across the automotive, medical, and consumer goods sectors.

Carbon Wins European Patent Appeal for Foundational 3D Printing Tech
A European Patent Office Board of Appeal has rejected a competitor’s challenge to Carbon’s core dual-cure 3D printing patent, effectively restoring the scope of the company's intellectual property. The decision validates European Patent No. 3158400, confirming the legal standing of the technology used in high-performance additive manufacturing.
Philip DeSimone, CEO of Carbon, stated that the decision confirms the breadth of the company's foundational innovation. He emphasized that the technology enables the manufacturing of high-performance parts that were previously impractical to produce through conventional additive methods. The company relied on legal counsel from Marks & Clerk, Myers Bigel, and Winston Taylor to navigate the proceedings. Moving forward, Carbon intends to continue its investment in protecting its proprietary manufacturing suite as it expands its footprint in digital production.
