Mike Murphy’s Enterprises v. Fineline Industries: Boat Wake Control Patent Dispute Ends in Voluntary Dismissal
After nearly eight years of litigation, a patent infringement dispute over boat wake control technology quietly concluded when both parties agreed to walk away. In Mike Murphy’s Enterprises, Inc. v. Fineline Industries, LLC (Case No. 1:16-cv-00784), filed in the California Eastern District Court on June 6, 2016, the case terminated on March 22, 2024, through a stipulated voluntary dismissal with prejudice — with each side bearing its own costs and attorneys’ fees.
At the center of this watercraft patent litigation was U.S. Patent No. 6,234,099 B1, covering an inboard engine water craft and boat wake control technique. The accused products included Centurion and Supreme boat lines manufactured by Fineline Industries, LLC.
For patent attorneys, IP professionals, and R&D teams operating in the recreational marine industry, this case illustrates the strategic calculus behind prolonged patent disputes and the growing prevalence of negotiated exits over courtroom verdicts — a trend with meaningful implications for IP portfolio management and litigation strategy.

Case Overview
The Parties
⚖️ Plaintiff
A company asserting rights over patented watercraft technology, specifically systems involving inboard engine wake management. As the patent holder, the company pursued claims of direct infringement.
🛡️ Defendant
Manufacturer of recreational performance watercraft, operating well-known boat brands including Centurion and Supreme. Both are established names in the wake sports industry.
The Patent at Issue
This case centered on **U.S. Patent No. 6,234,099 B1**, covering an inboard engine water craft and boat wake control technique. The patent covers technology directly relevant to performance wakeboarding and wakesurfing boats, where wake shape and size are critical product differentiators.

The Verdict & Legal Analysis
Outcome
On March 21, 2024, the parties filed a stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Chief Judge O’Neill subsequently ordered the Clerk to close the file, confirming the action’s termination with no award of costs or attorneys’ fees to either side.
Critically: no damages were awarded, no injunction was issued, and no judicial finding on validity or infringement was rendered. The case resolved entirely through party agreement.
Key Legal Issues
Because the case resolved via stipulated dismissal rather than judgment, there is no public judicial determination regarding:
- Whether the patent claims were valid
- Whether Fineline’s Centurion or Supreme boats actually infringed the asserted claims
- How key claim terms — such as “wake control technique” or the structural elements of the inboard engine watercraft — would have been construed
This outcome is legally significant precisely because of what it does not establish. A dismissal with prejudice bars the plaintiff from re-filing the same claims against the same defendant, but it creates no precedential claim construction or infringement finding that competitors or future defendants could rely upon.
The “with prejudice” designation is consequential: Mike Murphy’s Enterprises permanently relinquished its right to assert these specific infringement claims against Fineline Industries for the accused Centurion and Supreme product lines.

The case centered on U.S. Patent No. 6,234,099 B1 (Application No. US 09/456,131), covering a water craft with an inboard engine and boat wake control technique.
The parties filed a stipulated voluntary dismissal with prejudice on March 21, 2024, with each party bearing its own costs and attorneys’ fees — a negotiated resolution under Fed. R. Civ. P. 41(a)(1)(A)(ii).
The dismissal only bars claims against Fineline Industries for the accused products. Other manufacturers of wake control watercraft may still face exposure under US 6,234,099 B1.
