Fka Distributing v. Joicom & Renpho: Heated Massager Patent Dispute Ends in Stipulated Dismissal
Fka Distributing Co., LLC brought a patent infringement action in the Central District of California against Joicom Corporation, Panatrade LLC, and Renpho USA asserting US7722553B2 over heated Shiatsu massager products. The parties reached a stipulated resolution after 345 days, with the action dismissed with prejudice and each side bearing its own attorneys’ fees and costs.
Multi-defendant heated massager patent dispute resolved by stipulation before trial
Filed on 16 October 2023 in the U.S. District Court for the Central District of California, Fka Distributing Co., LLC alleged infringement of US7722553B2 — a patent covering heated Shiatsu massager technology — against three defendants: Joicom Corporation, Panatrade LLC, and Renpho USA, Inc. The accused products included multiple Amazon-listed Shiatsu massager SKUs. Brooks Kushman PC represented the plaintiff; Morgan, Lewis & Bockius LLP appeared for the defendants.
The case closed on 25 September 2024, 345 days after filing, via a court-ordered dismissal with prejudice entered on the stipulation of all parties and their counsel. Each party was ordered to bear its own attorneys’ fees and costs, suggesting the parties reached a private agreement — likely a settlement or licence — whose financial terms were not disclosed in the public record. A with-prejudice dismissal extinguishes plaintiff’s right to re-assert the same patent claims against these specific defendants.
The sub-12-month resolution across three defendants is consistent with early-stage negotiation or a structured licensing arrangement rather than protracted litigation. The mutual cost-bearing provision, rather than a fee-shifting award, typically signals a negotiated outcome rather than a clear-cut victory for either side. The specific financial terms, any licence grant, and which products may have driven settlement leverage remain unknown from the public record.

Stipulated dismissal with prejudice: what the order means for each party
Dismissal with prejudice by stipulation — no re-filing permitted
A dismissal with prejudice entered by stipulation is a final, binding termination of the action on the merits as to the named defendants. Fka Distributing cannot re-file the same infringement claims under US7722553B2 against Joicom, Panatrade, or Renpho USA arising from the same accused products. The court retains no further jurisdiction over those claims. This mechanism is a standard vehicle for memorialising a privately negotiated resolution without disclosing its terms.
Claim-preclusive as to named defendantsRe-filing foreclosed — private terms likely secured value
By agreeing to a with-prejudice dismissal, Fka Distributing permanently surrendered the right to litigate these claims against the three defendants under this patent. However, a stipulated with-prejudice dismissal accompanied by a mutual cost-bearing order strongly suggests an agreed resolution — potentially a licence fee or lump-sum payment — was reached privately. Plaintiffs rarely accept with-prejudice closure without obtaining some consideration; the public record is silent on the specific terms.
Private terms not publicly disclosedDefendants achieve finality — but private obligations may persist
Joicom, Panatrade, and Renpho USA obtained a final court order ending Fka Distributing’s infringement claims with no fee-shifting penalty, meaning no judicial finding of exceptional case conduct against them. They bear their own legal costs. However, any privately agreed terms — ongoing royalties, design-arounds, or product pull-down obligations — would not appear in the public record. Third-party competitors cannot assume the resolution was fee-free in a commercial sense.
No adverse fee award; private terms unknownUS7722553B2 remains enforceable against the broader market
The with-prejudice dismissal resolves only the claims against these three defendants. US7722553B2 remains in force and continues to pose infringement risk for other heated Shiatsu massager sellers and importers. The filing against multiple Amazon marketplace sellers signals Fka Distributing is active in enforcing this patent across the consumer massager space. Competitors offering similar heated massager products — particularly those sold via e-commerce platforms — should assess their exposure against the patent’s claims.

Official order — verbatim text
The court’s order adopts the parties’ stipulation verbatim, making clear this was a consensual resolution rather than a merits adjudication. The with-prejudice standard forecloses any future action on the same claims against these defendants, giving the defendants permanent protection from re-litigation under this patent. Critically, the absence of any fee or cost award — beyond each side bearing its own — is consistent with a privately negotiated settlement whose terms were deliberately kept off the public docket.
US7722553B2 — Heated Shiatsu Massager Device Technology
US7722553B2 was filed under application number US11/972071 and covers heated Shiatsu massager technology — a consumer personal-care device category combining rotary massage nodes with integrated heating elements. The patent protects the structural and functional design of such devices, which are widely sold as back, neck, and shoulder massagers via e-commerce platforms. The patent’s claims define the combination of heating functionality and massage mechanics that Fka Distributing alleged the defendants’ products embodied.
The heated personal massager segment is a high-volume, import-driven consumer electronics category where numerous SKUs compete on Amazon and similar platforms. The assertion of US7722553B2 against three separate marketplace sellers simultaneously suggests Fka Distributing views the patent as broadly applicable across the product category. For competitors in the heated massager space, this patent represents a meaningful risk vector — particularly for products featuring Shiatsu-style rotating nodes paired with a heating function — and should be evaluated in any product launch or import clearance review.
Should you run an FTO analysis against US7722553B2?
Any company designing, importing, or selling heated Shiatsu massager products — especially for the U.S. e-commerce market — should treat US7722553B2 as a live enforcement risk. The patent holder has demonstrated willingness to pursue multiple defendants simultaneously, and the stipulated resolution without a merits ruling leaves the claims’ full scope legally intact. Private-label brands, Amazon marketplace sellers, and contract manufacturers sourcing heated massager units should assess whether their product configurations fall within the patent’s claims before launch or continued distribution.
PatSnap Eureka’s FTO Search Agent enables R&D and product teams to map the claim language of US7722553B2 against their specific product architecture — including heating element placement, node configuration, and mechanical drive mechanisms. Eureka surfaces the closest prior art, identifies claim differentiation opportunities, and flags related family members or continuation risk. Run an FTO analysis before your next product listing goes live to avoid replicating the exposure that brought three defendants into this litigation.

What this case signals for the heated massager and personal-care device IP landscape
A fast stipulated dismissal across three defendants suggests active licensing leverage — and a patent still in play for the wider market.
Multi-defendant filings in C.D. Cal. signal coordinated enforcement campaigns
Filing against Joicom, Panatrade, and Renpho simultaneously — all apparent Amazon marketplace sellers of heated Shiatsu massagers — is consistent with a coordinated enforcement strategy targeting the import and resale channel rather than a single manufacturer. C.D. Cal. is a commonly chosen venue for consumer electronics and personal-care device patent actions due to its established patent docket and proximity to major importers.
No fee-shifting is consistent with early negotiated resolution, not defendant victory
The mutual cost-bearing order rules out an exceptional-case fee award under 35 U.S.C. § 285, but it does not signal defendant success on the merits. In stipulated dismissals of this kind, the absence of fee-shifting typically reflects a negotiated package where each side accepts its own litigation spend as part of the deal. Competitors should not interpret the outcome as a validation that the accused products are non-infringing.
Fka v Joicom — key questions answered
The case was dismissed with prejudice by stipulation of all parties on 25 September 2024, 345 days after filing. Each party bore its own attorneys’ fees and costs. No merits ruling was issued, and the financial terms of any underlying settlement were not publicly disclosed.
Fka Distributing asserted US7722553B2 (application no. US11/972071), which covers heated Shiatsu massager technology. The accused products included multiple consumer heated massager SKUs sold by the defendants, identified by Amazon product identifiers in the case record.
A with-prejudice stipulated dismissal bars Fka Distributing from re-filing the same infringement claims against Joicom, Panatrade, and Renpho USA under US7722553B2 for the same accused products. However, the patent itself remains valid and enforceable against third parties not named in the case, meaning other heated massager sellers retain full infringement risk.
The complaint identified Renpho USA, Inc. as one of three defendants alleged to have infringed US7722553B2 through the sale of heated Shiatsu massager products. Renpho is a significant consumer personal-care device brand with substantial Amazon marketplace presence, which likely made its product line a material target in a coordinated enforcement action across multiple sellers.
Yes. The stipulated dismissal with prejudice resolves only the claims against the three named defendants. US7722553B2 remains in force and has not been invalidated or limited by any claim construction ruling from this litigation. Companies selling heated Shiatsu massager products in the U.S. market should conduct an independent freedom-to-operate analysis against this patent before launching or continuing to distribute comparable products.
