United States: JOOLA Files Patent Infringement Complaint Against 11 Pickleball Paddle Brands

JOOLA has filed patent infringement litigation against 11 pickleball paddle manufacturers, alleging unauthorized use of its proprietary propulsion core technology.

The complaint, filed with the U.S. International Trade Commission (ITC) on April 7, 2026, targets several major brands in the rapidly growing pickleball equipment market. According to JOOLA, the legal action reflects its efforts to protect technology it says helped shape modern paddle performance.

Companies Named in the Complaint

The following companies were listed as defendants in the filing:

1. Franklin Sports
2. Proton Sports
3. RPM Pickleball
4. Engage Pickleball
5. Friday Labs
6. Diadem Sports
7. Facolos
8. ProXR Pickleball
9. Paddletek
10. Adidas Pickleball
11. Volair

JOOLA stated that the litigation centers on the alleged unauthorized use of its propulsion core technology, which the company says is protected by patents.

JOOLA Explains Decision to File

Richard Lee, CEO of JOOLA, said the decision to initiate litigation was deliberate.

“This is a principled decision, not a reactive one,” Lee said in a statement. “We take our responsibility to defend what we’ve built seriously. Our goal is to protect our innovation and encourage others to innovate as well.”

What Is the Propulsion Core Technology?

JOOLA’s propulsion core technology is used in its Pro IV and Pro V paddle models. According to the company, the patented design introduces controlled flex within the paddle, creating a spring-like effect intended to improve power and responsiveness.

The technology, sometimes described as a foam horseshoe or diving board, sits in the upper portion of the paddle rather than extending around the entire perimeter. JOOLA said the design allows players to generate greater power without increasing swing effort.

The company also noted that it invested years in research, development, and testing of the propulsion core technology.

“Protecting our innovation is not about limiting what others can do – it’s about ensuring the investment, creativity and engineering required to advance this sport are sustained,” Lee added.

Industry Impact

The filing could have significant implications for the pickleball equipment industry, which has experienced rapid growth in recent years. If the ITC finds infringement, potential remedies could include import restrictions or other enforcement measures affecting the accused products.

The case is expected to draw close attention across the industry as proceedings move forward.
