Continuous Composites Initiates Patent Infringement Suit Against Anisoprint After Failed Licensing Talks
Continuous Composites, Inc. (CCI), a notable innovator in advanced manufacturing platforms, has recently announced the initiation of a patent infringement lawsuit directed at Anisoprint S.a.r.l. and its affiliate Anisoprint 3D Printing Technology (Suzhou) Limited, operating under the name Fibre Seek. This legal action arises after years of unfruitful negotiations concerning licensing agreements, extending over a span of approximately three years.
The lawsuit centers on allegations that Fibre Seek's offerings, particularly the newly launched FibreSeeker 3 continuous fiber 3D printer, violate ten U.S. patents that CCI claims are fundamental to the processes involved in continuous fiber composite additive manufacturing. This is especially significant in an industry that relies heavily on intellectual property to innovate and push the boundaries of manufacturing technology.
The CF3D® technology developed by Continuous Composites represents groundbreaking advancements initiated by the patent application filed in 2012, marking it as one of the earliest steps in continuous fiber additive manufacturing. Since then, the company has expanded its intellectual property portfolio impressively, boasting over 120 permitted U.S. patents and more than 40 patents granted internationally, focusing on advanced composite manufacturing methodologies.
Steve Starner, the CEO of Continuous Composites, emphasized that the dispute is rooted in multiple overlapping patents rather than a single feature. He stated, "The complaint involves claims across ten separate U.S. patents that cover core technologies crucial for establishing continuous fiber additive manufacturing as a commercially viable process." The heart of the controversy lies in methodologies and systems that facilitate the combination of continuous reinforcement fibers with polymer matrix materials during additive manufacturing, which CCI has developed in detail over a decade of intensive research and engineering.
Engagement with Fibre Seek began in 2023 as Continuous Composites sought to reach a mutual understanding regarding the protection of its patent portfolio and the need for a licensing arrangement. By mid-2024, CCI presented a licensing proposal aimed at enabling Fibre Seek to operate without infringing upon CCI’s intellectual property rights. However, additional attempts to reach an agreement proceeded in 2024 and 2025 without success, prompting the current lawsuit.
Starner noted, "We did not rush into litigation. For nearly three years, we endeavored to resolve this matter through direct engagement, good-faith discussions, and various opportunities to establish a licensing agreement. Litigation became necessary only when these efforts reached a standstill." He underscored the importance of protecting the nearly fifteen years’ worth of investments, engineering advancements, and commercialization efforts that underpin their patented technologies.
While the litigation process is ongoing, Continuous Composites refrains from making further comments beyond what has been filed publicly in court documents, adhering to judicial protocol.
Continuous Composites continues to champion the future of composite manufacturing through its CF3D® technology. This innovative platform integrates fiber steering, advanced materials, and automated manufacturing to create high-performance structures with remarkable design agility, catering specifically to aerospace, defense, and unmanned aerial vehicle (UAV) sectors. As the legal proceedings unfold, CCI remains steadfast in its commitment to safeguarding the innovations and contributions made not only by the company itself but also by its employees, customers, partners, and investors.
