Prime Time Toys v. Spin Master: Voluntary Dismissal in Water Projectile Patent Dispute
In a case that quietly closed as quickly as it opened, Prime Time Toys LLC v. Spin Master, Inc. concluded with a voluntary dismissal at the Court of Appeals for the Federal Circuit on February 23, 2026 — just 75 days after it was filed. The dispute centered on U.S. Patent No. 8,596,255 B2, covering a super absorbent polymer (SAP) projectile launching device, a technology that sits at the intersection of children’s toy innovation and competitive IP strategy.
The case was rooted in a patentability challenge — specifically an invalidity or cancellation action — suggesting Spin Master sought to invalidate Prime Time Toys’ patent rather than simply defend against infringement. The parties ultimately agreed to dismiss the Federal Circuit proceedings under Fed. R. App. P. 42(b), with each side bearing its own costs — a neutral outcome that nonetheless carries meaningful signals for patent practitioners and toy industry IP professionals alike.
For patent attorneys tracking post-grant proceedings and appeal strategy, and for R&D leaders navigating freedom-to-operate in the competitive toy market, this case offers instructive takeaways.

The Verdict & Legal Analysis
Outcome
The Federal Circuit dismissed Case No. 26-1239 pursuant to Fed. R. App. P. 42(b), a voluntary dismissal upon stipulation of the parties. No damages were awarded, no injunctive relief was granted or denied, and no substantive merits ruling was issued. Each side was ordered to bear its own costs. The case is classified as closed, with the verdict cause identified as Patentability under an Invalidity/Cancellation Action.
Key Legal Issues & Strategic Implications
Because the dismissal was voluntary and stipulated, the Federal Circuit issued no ruling on the merits of the patentability challenge. This means no claim construction ruling or invalidity finding was made. The underlying challenge likely originated from an inter partes review (IPR) petition or a related post-grant proceeding at the USPTO. The rapid dismissal suggests a negotiated resolution, reflecting the appeal filing’s settlement pressure and neither party achieving a clear win on the merits.

✅ Key Takeaways
For Patent Attorneys & Litigators
Voluntary Rule 42(b) dismissals at the Federal Circuit often signal off-docket settlements; monitor related USPTO prosecution or licensing activity for context.
Search related case law →Invalidity/cancellation appeals that resolve pre-briefing suggest strong settlement leverage was created by the appeal filing alone.
Explore precedents →For R&D Leaders
Super absorbent polymer projectile technology is actively patented and litigated — FTO clearance is essential before product launch or design modification.
