Untitled case

Moskowitz Family LLC, identified as a well-funded non-practicing entity (NPE), initiated this patent infringement lawsuit against Medtronic Inc., Medtronic Sofamor Danek Inc., Medtronic Sofamor Danek USA, Inc., Titan Spine Inc., and Warsaw Orthopedic Inc., all operating companies in the medical device industry. The lawsuit, filed on February 28, 2025, in the District of Minnesota, alleges infringement of U.S. Patent No. 11,864,755, and potentially other patents not explicitly detailed in the initial filings but hinted at by broader IPR discussions. The accused products are spinal interbody devices manufactured and sold by the Medtronic entities.

The asserted patent, U.S. Patent No. 11,864,755, generally relates to a disposable infant co-sleeper system and methods of its use, including a stand and a removable sleeping cavity designed for safe infant co-sleeping and ease of disposal. This technical area, focusing on infant care products, appears to diverge significantly from the accused spinal interbody devices, suggesting a potential broader portfolio of patents held by Moskowitz Family LLC or a strategic assertion that might encompass aspects of manufacturing or material science relevant to both domains. The case is assigned to Judge Jerry W. Blackwell and referred to Magistrate Judge Douglas L. Micko, within the District of Minnesota, a venue that has seen significant patent litigation.

This case is notable due to Moskowitz Family LLC's classification as an NPE with a history of asserting patents against medical device companies. For instance, Moskowitz has previously sued Medtronic's competitors, such as Globus Medical and ZimVie, indicating a pattern of enforcement within the medical sector. While the current filing explicitly mentions patent 11864755, which technically covers infant co-sleepers, the accused product being spinal interbody devices points to a likely dispute over claim interpretation or the assertion of other, undisclosed patents within the same case, or a highly aggressive and broad interpretation of the listed patent's applicability. Furthermore, there is an indication of related inter partes review (IPR) proceedings against other patents asserted by Moskowitz Family LLC against Medtronic, though the specific IPR for 11864755 and its direct linkage to this case's asserted claims would require further detailed investigation. The district court trial in Minnesota is not expected to occur until February 2028 at the earliest.
