The pickleball equipment industry has entered a new era — one measured not just in test-lab RPM figures and PBCoR coefficients, but in patent numbers and federal court filings. On June 16, 2026, JOOLA announced a settlement with Proton Sports, the third brand to resolve claims with the Maryland-based giant since its sweeping April 7 filing with the United States International Trade Commission. The industry is watching closely. Eight defendants remain, and none of them appear ready to wave the white flag.

A Two-Track Legal Blitz
JOOLA's legal architecture is as engineered as its paddles. The company chose to file simultaneously on two fronts: the International Trade Commission and multiple federal district courts. The combination is deliberately punishing.
The district court suits seek substantial monetary damages — but those cases move slowly. The ITC track operates at a different tempo entirely. Because nearly all major pickleball paddle components are manufactured overseas, an ITC limited exclusion order would not just impose fines. It would stop infringing paddles from crossing the U.S. border at all, effectively freezing defendants out of the domestic retail market while appeals wind through the courts.
"JOOLA's Propulsion Core technology is the foundation of the modern pickleball paddle, and we are pleased to have reached a resolution with Proton. We will continue to pursue fair outcomes with the remaining defendants as we protect the technology we built that defines the modern game."
— Richard Lee, CEO, JOOLA
The Proton Settlement: Terms in Detail
The June 16 settlement resolves all claims connected to Proton's Flamingo Series 3 paddle. Under the terms agreed to, Proton will halt manufacturing of the affected model immediately. However, the company is permitted to sell down its existing retail inventory through the end of summer — a provision designed to reduce immediate channel disruption.
That sell-through right comes with conditions. Proton must pay ongoing royalties to JOOLA on each unit sold, print JOOLA's two patent numbers on the paddles themselves, and affix a "Powered by JOOLA" sticker to all remaining packaging. The sticker requirement, echoing similar terms in the Paddletek and ProXR settlements, functions as a form of public IP acknowledgment embedded directly in the retail experience.
Proton founder and CEO Charles Darling took a conciliatory tone in his statement, calling the outcome constructive and acknowledging JOOLA's role in defining modern paddle technology. That framing — closely mirroring the language from the Paddletek Group settlement in May — suggests legal teams across these brands are recognizing the weight of JOOLA's patent claims.
The following brands remain as active defendants in both ITC proceedings and parallel federal litigation as of June 2026:
"We respect JOOLA's intellectual property and its impact on the pickleball paddle market, as well as JOOLA's role as a leader in technical innovation. We are glad to resolve this matter constructively."
— Charles Darling, Founder & CEO, Proton Sports
What the Settlements Signal
Three settlements in roughly ten weeks, each arriving faster than the last, tells you something about how legal teams are privately assessing JOOLA's claims. The Paddletek Group settled in approximately five weeks — a pace that suggested confidence in JOOLA's patents ran low among the defendants' counsel. ProXR followed immediately. Proton's June resolution continues the pattern.
The settlement terms themselves are instructive. None of the settling brands have redesigned around the patents. They're paying royalties and phasing out affected products — the path of least resistance. That suggests either the engineering challenge of building a compliant, competitive Gen 3 alternative is significant, or the royalty terms are economically preferable to a fight. Likely both.
The notable absence in the original filing remains Selkirk, whose Era Power uses foam that runs all the way around the core rather than in JOOLA's targeted U-shaped upper-half configuration. That design boundary — and JOOLA's apparent deliberate choice not to target it — may define the direction of paddle engineering for brands choosing to build their way out of the IP landscape rather than license their way through it.
- ITC proceedings continue for all 8 remaining defendants — a ruling could restrict U.S. imports of infringing paddles across the board
- Brands may accelerate R&D into full-perimeter foam configurations or entirely non-foam core architectures to sidestep the patents
- Each additional settlement strengthens JOOLA's negotiating position with remaining defendants and validates patent scope
- If any remaining brand chooses to fight rather than settle, the resulting ITC ruling could set binding precedent for the entire industry
- Licensing fees embedded in retail pricing may begin shifting the cost-structure advantage of foreign-manufactured paddles
The pickleball equipment industry has spent years competing on innovation. JOOLA has now established that it intends to compete on IP ownership too. How the remaining eight defendants respond — through settlement, redesign, or litigation — will define the structural landscape of performance paddle manufacturing for years to come.
