Case Overview
The Parties
⚖️ Plaintiff
Irish company specializing in underwater imaging and photogrammetry systems, holding patents for subsea camera and lighting technologies.
🛡️ Defendant
Canadian firm developing underwater laser scanning and imaging systems, including the commercially significant RECON CS and RECON LS products.
Patents at Issue
This multi-year dispute centered on two U.S. patents covering advanced underwater imaging technology. These innovations are foundational to high-fidelity underwater survey operations and address camera synchronization, lighting control, and image capture optimization in subsea environments.
- • U.S. Patent No. 10,116,842 B2 — Underwater Imaging System Architectures
- • U.S. Patent No. 10,116,841 B2 — Underwater Imaging System Architectures

The Verdict & Legal Analysis
Outcome
The case concluded on **March 1, 2024**, with a **dismissal with prejudice** pursuant to a joint Rule 41(a)(1)(A)(ii) stipulation filed by both parties. This resolution, accepted by Chief Judge Schroeder, indicates a negotiated settlement was reached, with each party agreeing to bear its own costs, expenses, and attorneys’ fees. All claims and counterclaims were dismissed permanently.
Key Legal Issues
The absence of a judicial ruling on infringement, validity, or claim construction means the legal record offers limited doctrinal guidance. However, the dismissal with prejudice is significant: neither party may re-litigate the same claims. The mutual cost-bearing clause suggests a balanced negotiation, where neither side secured clear litigation dominance, and the dismissal of counterclaims indicates 2G Robotics mounted substantive validity challenges to the ‘842 and ‘841 patents. Critically, because the case resolved without a merits ruling, the ‘842 and ‘841 patents remain legally valid and enforceable. Cathx Research retains full assertion rights against other potential infringers in the underwater imaging space.
