Case Overview
The Parties
⚖️ Plaintiff
The technology commercialization arm of Florida State University, managing the university’s intellectual property portfolio and licensing agreements.
🛡️ Defendant
A Florida-based commercial entity involved in highly efficient linear motor products, placing it within FSURF’s enforcement scope.
Patents at Issue
This case centered on two granted U.S. patents covering highly efficient linear motor technology, a field drawing increasing commercial and defense-sector attention. Linear motors convert electrical energy directly into linear mechanical motion, deployed in applications including transportation systems, manufacturing automation, and aerospace actuators.
- • U.S. Patent No. 10,601,293 B2 — covering innovations in highly efficient linear motor design and architecture
- • U.S. Patent No. 10,774,696 B2 — covering related linear motor technology, likely addressing complementary system components or operational methods

The Verdict & Legal Analysis
Outcome
The case terminated via stipulated dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(ii), effective without court order upon filing. This procedural designation means FSURF cannot re-file the same claims against SentiMetal Journey for the same conduct. No damages award, royalty determination, or injunctive relief was publicly entered, suggesting a private resolution such as a licensing agreement or design-around was reached.
Legal Significance
For linear motor patent infringement litigation, this case reinforces a consistent pattern: university research foundation patent assertions frequently resolve through private agreement before trial. The two patents involved represent substantive R&D investment by FSU researchers, and their survival through litigation without invalidity findings preserves their future licensing utility. The case also affirms that Rule 41(a)(1)(A)(ii) stipulated dismissals under *Anago Franchising, Inc. v. Shaz, LLC*, 677 F.3d 1272, 1278 (11th Cir. 2012) remain the preferred resolution vehicle in the Eleventh Circuit when both parties seek a clean exit without judicial merits determination.

The case involved U.S. Patent No. 10,601,293 B2 (Application No. 16/370,576) and U.S. Patent No. 10,774,696 B2 (Application No. 15/947,131), both covering highly efficient linear motor technology.
The parties filed a joint stipulation of dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(ii). No court order was required. Specific settlement terms were not publicly disclosed, but such dismissals often reflect private licensing agreements or product design-arounds.
The patents remain valid and enforceable. Companies in the linear motor space should treat both patents (US10601293B2 and US10774696B2) as active licensing and enforcement risks and conduct freedom-to-operate analysis accordingly. This also underscores that university technology transfer offices are active in monetizing their IP.
