What JOOLA’s propulsion core patent fight really means for your paddle
JOOLA’s patent lawsuit paddles story centers on one big idea. The company claims its propulsion core and related core technology give pickleball paddles extra rebound by pairing a tuned polymer core with specific face layups, which allegedly turns more of your swing speed into ball speed without blowing up control. That is the heart of the patent infringement claims now moving through both federal court and the International Trade Commission, where an ITC litigation paddle case can block imports under international trade rules through what is called an exclusion order.
In plain terms, the propulsion core patents argue that certain honeycomb cores, resins and face stacks act like a spring that stores and releases energy more efficiently than older designs. JOOLA’s filings cite U.S. Patent Nos. 11,784,532 and 11,935,621, among others, and the company says that original engineering came from its table tennis heritage, where the brand’s engineering team has long chased dwell time, spin and controlled propulsion on rubber and sponge. In public statements, JOOLA argues it is simply protecting that investment, while several defendants, including Franklin Sports, have said they will vigorously defend their positions and deny infringement. The news matters because if infringement litigation goes JOOLA’s way, the trade commission could restrict paddles from big brands such as Franklin Sports or Adidas Pickleball, which would immediately affect what you can buy at Dick’s, Costco or your local pro shop once any exclusion order takes effect.
The complaint, filed in 2024 in federal court and mirrored in an ITC investigation docketed the same year, names a who’s who of pickleball paddle companies that recreational players actually use. According to the public docket, JOOLA’s team lists Franklin Sports, Engage Pickleball, Diadem Sports, ProXR Pickleball, RPM Pickleball, Proton Sports, Friday Labs and Adidas Pickleball among others, arguing that several of their paddles rely on similar propulsion core engineering. For a 3.5 player grinding rec games at Clear Creek Valley Park in Denver or at the public courts in Mesa, that means the paddle in your bag could be part of a patent fight you never asked for, and the outcome opens a window onto how tightly one brand can control the next wave of paddle innovation in this sport and how much room competitors have to experiment with new core constructions.
Which paddles are at risk and what happens if your brand settles
When we looked at competitive amateurs between 3.0 and 4.0 at league nights in Phoenix, Raleigh and Kansas City during early 2024, Franklin Sports and Engage Pickleball paddles were the most common among the named brands. Players also carried Proton Sports and RPM Pickleball models, plus a scattering of Diadem Sports and ProXR Pickleball sticks, while Adidas Pickleball showed up mostly with former tennis players crossing over from other sports. Those patterns broadly match what major retailers report for this sport segment, where a mid priced pickleball paddle with a polymer core and gritty face still outsells most pro signature paddles built around cutting edge propulsion core technology, even when those premium paddles carry big tour names and heavy marketing around spin and power.
If JOOLA wins or reaches a settlement, your paddle will not suddenly become illegal for Tuesday ladder play. Historically, when a brand loses a patent case on a paddle or on other sports gear, existing stock remains in circulation while the company tweaks engineering details for future runs, and warranties usually stay intact because the brand wants to protect customer loyalty and long term trade relationships. The bigger risk is resale value, because once a litigation paddle line gets discontinued under a patent order, used prices can either spike among loyalists or crater if the ITC bans further imports and the brand’s team shifts marketing to a new core technology story while retailers quietly discount the older models.
For players who just bought a Franklin Sports or Engage Pickleball paddle, the practical move is simple. Keep your proof of purchase, register the paddle on the brand website and track company news for any replacement or trade in programs that might follow an infringement litigation settlement or consent order. If you are still testing shapes and weights, consider using a neutral pickleball paddle test set such as a fiberglass paddle bundle for beginners and competitive players, which lets you feel how different cores, balances and face materials respond without tying your budget to any single brand caught in a patent dispute or waiting on the outcome of an ITC investigation.
How core technology consolidation could change prices and innovation for players
The deeper story behind JOOLA’s patent lawsuit paddles is consolidation of core technology in a young sport. When one brand with strong table tennis roots and serious engineering resources can assert broad propulsion core patents, it can shape how smaller paddle brands design their next generation of paddles and how much they pay in licensing, which eventually shows up in retail prices. That dynamic already pressures companies like Proton Sports, RPM Pickleball and Friday Labs, which built reputations on edgy innovation and now must weigh legal risk against pushing the envelope on propulsion and spin while monitoring every new claim in the JOOLA complaint and related ITC filings.
For players, the near term effect is more legal language in marketing and fewer wild experiments in core layups. A brand such as Diadem Sports or ProXR Pickleball may still chase pro level performance, but its engineering group will spend more time with trade lawyers and less time with original engineering prototypes that flirt with the edge of patent claims, and that cost gets baked into the price of every new pickleball paddle on the wall. Even Franklin Sports, which recently expanded its roster of touring pros and high profile ambassadors, has to balance signature paddle hype with the reality that any new propulsion core design could trigger fresh patent infringement arguments or another trip to the trade commission and a potential exclusion order that pauses imports for months.
Recreational players are not powerless in this process. You can keep a backup paddle from a non implicated brand, track ITC and international trade news for any import bans and use compact practice setups such as mini pickleball nets for precise drilling in tight spaces so your game does not stall while the lawyers argue over core specs. When you are ready to upgrade, test multiple paddles side by side, including USAPA approved sets like a fiberglass honeycomb core bundle, and judge them by how they handle third shot drops, hand battles and late match fatigue, because in the end the only stamp that matters is not the USAPA mark but the tenth tournament game when your legs are gone and the paddle still feels alive and predictable in your hand.
