Hyper Ice v. Schedule A Defendants: Default Judgment & Permanent Injunction in 43 Days
Hyper Ice, Inc. and Hyperice IP Subco, LLC sued more than 30 Amazon marketplace sellers for infringing US11857482, a utility patent covering battery-powered percussive massagers. Judge Roy K. Altman granted a final default judgment and permanent injunction on June 20, 2024 — just 43 days after filing — after all remaining defendants failed to appear.
Amazon ‘Schedule A’ enforcement: Hyperice wins swift default judgment
On May 8, 2024, Hyper Ice, Inc. and Hyperice IP Subco, LLC filed suit in the Southern District of Florida against a broad group of Amazon marketplace sellers — identified through a ‘Schedule A’ — alleging utility patent infringement of US11857482, which protects battery-powered percussive massager technology. Plaintiffs were represented by Epstein Drangel LLP, a firm experienced in Schedule A e-commerce enforcement. Named defendants included entities such as BOCHUANG, Fit King, Recoverfun, Shenzhen Cincom E-Commerce, and more than 25 additional sellers operating storefronts under Chinese-entity DBA names.
The case resolved with a plaintiff win on June 20, 2024, via final default judgment and permanent injunction under Fed. R. Civ. P. 55 and 35 U.S.C. §§ 283–284. Several defendants appeared and were dismissed without prejudice during the litigation; the remaining non-appearing defendants were defaulted on June 13, 2024. The court awarded lost-profits damages calculated from Amazon Gross Merchant Value data, with defendants bearing the forfeited burden of cost apportionment. A permanent injunction prohibits further promotion, sale, and importation of infringing goods and requires removal of infringing Amazon listings.
The 43-day resolution is notably fast even for Schedule A default matters, suggesting defendants made no coordinated defense. The speed and breadth of the TRO-to-permanent-injunction pipeline — TRO granted May 10, preliminary injunction June 11, default judgment June 20 — is consistent with Hyperice’s use of a well-worn enforcement playbook. The precise quantum of damages awarded is referenced in the Kenneth Cohen affidavit but is not stated in the publicly available order; the separate final judgment order would contain the specific monetary figure.
Filing to Injunction Granted in 43 days
43 days — significantly faster than the median S.D. Florida patent case disposition
Default judgment granted: what the permanent injunction means for both sides
Default judgment under Rule 55: liability established by non-appearance
Under Fed. R. Civ. P. 55, when defendants are properly served but fail to appear, plead, or otherwise defend, the court may enter default and subsequently default judgment. Here, the court found Hyperice’s complaint well-pled and the claim chart evidence sufficient to establish infringement of US11857482 without a contested hearing. The defaulting defendants’ silence was treated as admission of the complaint’s well-pleaded factual allegations.
Rule 55 default judgmentHyperice secures permanent injunction and lost-profits damages
Hyper Ice obtained the full relief sought: a permanent injunction barring infringing sales, importation, and Amazon listings, plus lost-profits damages calculated on defendants’ full Gross Merchant Value — since no defendant appeared to apportion costs. The injunction restores Hyperice’s right to exclude and removes infringing products from the marketplace. Costs of suit were also awarded, and the order signals potential treble damages under 35 U.S.C. § 284 for willful infringement.
Full plaintiff relief grantedNon-appearing sellers face injunction, damages, and listing removal
The 22 defaulting defendants — largely Chinese-entity Amazon sellers — now face a permanent injunction, monetary judgment based on full GMV without cost deductions, and mandatory removal of infringing Amazon storefronts. Defendants who chose to appear and were dismissed without prejudice retain exposure to re-filing. The default judgment forecloses the right to contest liability or damages at this level, though defendants could theoretically seek to set aside default under Rule 55(c) by showing good cause.
Judgment by default — no contestPercussive massager IP: enforcement template for e-commerce infringers
This outcome reinforces the S.D. Florida Schedule A docket as an effective enforcement venue against Amazon marketplace sellers of consumer health and wellness devices. The TRO-to-permanent-injunction timeline of under six weeks — combined with Amazon third-party discovery for GMV data — represents a scalable playbook. Competitors and adjacent product makers in the percussive massager and handheld recovery device space should treat US11857482 as an active enforcement asset with demonstrated litigation backing.

Official order — verbatim text
The order grants Hyperice’s motion for final default judgment and permanent injunction in full, establishing liability for infringement of US11857482 based on well-pled complaint allegations and an uncontested claim chart. Because no defendant appeared, the court did not apply a claim construction standard; liability was established by default under Rule 55, not by adjudicated merits. The lost-profits damages award — calculated on full Amazon GMV — reflects the court’s application of the defendant-bears-apportionment-burden rule when no cost evidence is submitted. The injunction satisfies all four eBay factors, with irreparable harm supported by the defendants’ refusal to participate.
US11857482 — Battery-Powered Percussive Massager Technology
US11857482B1 is a utility patent assigned to Hyper Ice, Inc. and Hyperice IP Subco, LLC, issuing from application number US17/681367. The patent protects battery-powered percussive massager technology — handheld devices that deliver rapid repetitive strikes to soft tissue for muscle recovery and pain relief. As a utility patent under 35 U.S.C. § 271, it covers functional aspects of the device including, based on the claim chart evidence submitted, structural and operational limitations related to the percussion mechanism, motor integration, and battery power system. The patent was actively enforced within its lifespan, consistent with a commercially valuable product category.
The percussive massager market has grown sharply with consumer demand for at-home recovery devices, attracting a large number of competing products — particularly lower-cost alternatives sold through Amazon by offshore manufacturers. US11857482 represents Hyperice’s effort to establish proprietary claim scope over key technical features of its flagship Hypervolt-line products. For competitors and new market entrants, this patent creates a meaningful freedom-to-operate risk: the claim chart submitted in litigation maps the patent’s limitations onto commercially available Amazon SKUs, meaning the enforced claim scope is broad enough to capture mass-market alternatives, not just direct copies.
Should you run an FTO analysis against US11857482?
Any company designing, importing, or selling battery-powered percussive massagers — including handheld massage guns and similar soft-tissue recovery devices — should treat US11857482 as a priority FTO target. This patent has demonstrated enforcement teeth: a permanent injunction was obtained against 22 Amazon sellers within 43 days of filing. Product teams at OEMs, importers, and private-label brands selling in the U.S. market, particularly on Amazon, face direct exposure if their devices map onto the asserted claims. The risk is compounded if your products are shipped into or fulfilled from Southern Florida, which the court confirmed as a proper venue.
PatSnap Eureka’s FTO Search Agent can map the independent claims of US11857482 against your product specifications, identify design-around opportunities, and surface prior art that may support invalidity arguments if you face enforcement. Eureka also tracks continuation applications stemming from US17/681367, alerting you to emerging claim scope before new patents issue. For in-house IP teams and outside counsel advising clients in the recovery device space, a targeted FTO report on the ‘482 patent family is a prudent first step before any U.S. product launch or Amazon listing.

Portfolio viewWhat this case signals for the percussive massager IP landscape
Hyperice’s 43-day default win demonstrates credible, rapid enforcement of US11857482 against e-commerce sellers — a signal the market should not ignore.
Schedule A default actions are a proven fast-track IP enforcement tool
Hyperice’s strategy — TRO, preliminary injunction, Amazon GMV discovery, then default judgment — completed in 43 days. For patent holders in consumer wellness and wearable recovery tech, this S.D. Florida docket pattern offers a replicable enforcement route against marketplace infringers who are unlikely to appear.
GMV-based damages create significant financial exposure for non-appearing sellers
Because defaulting defendants failed to submit cost data, the court calculated lost profits on full gross revenue — not net margin. Any Amazon seller in the percussive massager category who receives a complaint should treat non-appearance as a high-risk strategy; the damages exposure without cost apportionment can far exceed actual net profits.
US11857482 claim scope: what products are actually at risk?
The claim chart filed at ECF No. 5-3 maps US11857482’s limitations onto competing percussive massager SKUs sold on Amazon. Understanding which claim elements drove the infringement finding — motor type, percussion frequency, battery integration — is critical for any product team designing in this space. FTO clearance against the ‘482 patent’s independent claims should be a baseline requirement before market entry.
Hyperice’s enforcement pattern: portfolio breadth and litigation velocity
Hyper Ice’s use of Epstein Drangel LLP — a specialist Schedule A enforcement firm — and the IP holding structure through Hyperice IP Subco, LLC suggests an institutionalised enforcement programme. Monitoring Hyperice’s patent portfolio filings and continuation applications is advisable for competitors; the ‘482 patent may be one of several assets in active or planned enforcement.
Hyper v Individuals — key questions answered
Hyper Ice asserted US Patent No. 11,857,482 (application no. US17/681367), a utility patent covering battery-powered percussive massager technology. The patent is owned by Hyper Ice, Inc. and Hyperice IP Subco, LLC, and was enforced against Amazon marketplace sellers operating under Schedule A seller IDs.
The remaining defendants were properly served but failed to appear, answer, or plead to the complaint. Under Fed. R. Civ. P. 55, the Clerk entered default on June 13, 2024. Judge Altman found the complaint well-pled and the claim chart evidence sufficient to establish liability, granting final default judgment and a permanent injunction on June 20, 2024 without an evidentiary hearing.
Damages were calculated based on Gross Merchant Value (GMV) — the total sales price of infringing goods multiplied by units sold — obtained from Amazon through third-party discovery. Because no defendant appeared to submit cost deductions or apportion infringing versus non-infringing sales, the court awarded lost profits based on the full GMV figure. The specific dollar amount is contained in the separate final judgment order.
The permanent injunction prohibits the defaulting defendants from promoting, selling, offering for sale, and importing goods that infringe US11857482 within the United States. It also requires removal of infringing Amazon listings and destruction of infringing inventory. The injunction was issued under 35 U.S.C. § 283 after the court found all four eBay factors satisfied.
Several defendants who appeared during the litigation were dismissed without prejudice from the case, per the court’s docket. The order does not specify the terms of those dismissals, so it is unclear whether they involved settlements or other resolutions. The remaining non-appearing defendants proceeded to default judgment.
