Audiowear Technology v. Schedule A Defendants: Default Judgment on Audio Hat Patent
Audiowear Technology Corporation secured a default judgment and permanent injunction against anonymous online marketplace sellers infringing its audio hat patent (US8491146B2). The Illinois Northern District Court awarded $10,000 in statutory damages per defendant for willful infringement, with platform providers eBay and PayPal ordered to freeze and release defendant funds within 14 days.
Audiowear wins default judgment against anonymous hat sellers on eBay
Filed on 19 September 2024 in the Northern District of Illinois, Audiowear Technology Corporation brought a patent infringement action against an anonymous group of online marketplace sellers identified only as ‘Schedule A’ defendants — a common enforcement technique targeting counterfeit and infringing goods sold through platforms such as eBay. The patent at issue, US8491146B2, covers audio hats: wearable headwear with integrated audio speaker or headphone technology. The defendants allegedly manufactured, listed, and sold infringing audio hat products through unauthorised online storefronts.
The case closed on 11 March 2025 via default judgment after the defendants failed to appear or respond. Judge LaShonda A. Hunt granted Audiowear’s Motion for Entry of Default and Default Judgment in full. The court issued a permanent injunction barring defendants from any further manufacture, sale, marketing, or distribution of infringing products. Third-party platforms eBay and PayPal were ordered to freeze and remit defendant account funds to Audiowear within 14 calendar days, providing immediate enforcement leverage without cooperation from the defendants themselves.
At 173 days from filing to closure, the case moved at a pace consistent with uncontested Schedule A enforcement actions. The default outcome suggests defendants either could not be meaningfully served or made a commercial calculation to abandon the storefronts rather than mount a defence. The public record does not disclose how many distinct defendants were ultimately identified on Schedule A, making total damages exposure difficult to quantify precisely — though the per-defendant $10,000 statutory award for willful infringement could aggregate substantially across multiple aliases and storefronts.

What default judgment means in a Schedule A case
When defendants in a patent infringement action fail to appear or respond to a complaint, a plaintiff may move for default judgment under Fed. R. Civ. P. 55. Here, the court accepted Audiowear’s allegations as admitted and granted the full relief requested — permanent injunction plus statutory damages — without any merits contest. This is the standard resolution pathway in Schedule A enforcement campaigns, where defendants are often pseudonymous overseas sellers who abandon storefronts once sued.
Unopposed — defendants did not appearAudiowear secures injunction and direct access to defendant funds
Audiowear obtained everything it sought: a permanent injunction covering all manufacturing, distribution, and sale channels; an order compelling eBay and PayPal to freeze and release defendant account balances as partial payment of damages; and ongoing authority to pursue supplemental proceedings under FRCP 69 until full payment is recovered. The $3,000 bond posted at filing was also returned. This outcome delivers immediate commercial enforcement value even if individual defendant recoveries are modest.
Full relief granted to plaintiffPlatform accounts disabled, funds seized — no appeal on the merits
Each distinct defaulting defendant faces $10,000 in statutory damages for willful infringement, permanent injunction compliance obligations, and account freezes across eBay and PayPal. Because judgment was entered by default, defendants forfeited the right to contest the patent’s validity, scope, or whether their products actually infringed. Any defendant wishing to challenge the judgment would need to move to vacate default — a procedurally difficult and uncertain path — before raising any substantive defence.
Per-defendant $10K statutory awardPlatform liability pull-through strengthens audio wearable IP enforcement
The court’s order directly engaging eBay and PayPal as enforcement intermediaries — compelling fund freezes and account disablement — illustrates how Schedule A actions create structural deterrence beyond the named defendants. For the audio hat and wearable audio sector, this judgment signals that US8491146B2 is actively enforced and that marketplace sales channels carry direct exposure. Sellers of integrated audio headwear products on major platforms should treat this case as a material FTO signal.

Official order — verbatim text
The default judgment order is notably comprehensive in its third-party reach. Rather than simply enjoining the named defendants, the court extended enforcement obligations to platform providers — eBay, PayPal, Amazon Pay — requiring fund freezes and account disablement within tight seven-to-fourteen-day windows. The alias-collapsing provision (one $10,000 award per distinct defendant regardless of multiple listed aliases) suggests the court was alert to the common tactic of operating multiple storefronts under different names. The supplemental proceedings authority under FRCP 69 means Audiowear’s enforcement rights persist beyond the judgment date.
US8491146B2 — integrated audio speaker technology in wearable hats
US8491146B2, filed under application number US12/980548, covers audio hats — wearable headwear incorporating integrated audio components such as speakers or headphone elements. The patent sits at the intersection of consumer electronics and wearable accessories, a product category that has grown significantly with the proliferation of wireless audio technology. The patent’s protection of the structural and functional integration of audio components into hat form factors defines the core infringement boundary for this case.
For the wearable audio accessories market, US8491146B2 represents an actively enforced property that Audiowear has demonstrated willingness to pursue through full-scale litigation including platform-level injunctive relief. Competitors and OEM suppliers in the audio hat category — particularly those selling through eBay, Amazon, and similar marketplaces — face meaningful exposure if their products integrate audio components into headwear in ways covered by the patent’s claims. The willful infringement finding in this case, even by default, sets a reference point for damages calculations in any future contested action.
Should your audio hat product be cleared against US8491146B2?
Any R&D team, sourcing manager, or brand developing headwear with integrated audio speakers, Bluetooth receivers, or headphone elements should treat US8491146B2 as a priority FTO target. Audiowear has demonstrated it will pursue platform-based enforcement — meaning marketplace listings, not just manufacturing, create exposure. This matters especially for private-label importers and dropshippers who may be several steps removed from the original manufacturer.

What this case signals for the audio wearable IP enforcement landscape
This default judgment reinforces the Schedule A playbook as an effective tool for audio wearable patent holders targeting anonymous online sellers.
Schedule A enforcement creates platform-level deterrence, not just defendant-level
By compelling eBay and PayPal to freeze and transfer funds without defendant cooperation, Audiowear achieved enforcement that survives seller anonymity. Any company selling audio hats or integrated audio headwear on major marketplaces should assess whether their products fall within the scope of US8491146B2 — regardless of whether they have received a direct demand letter.
Willful infringement finding raises the stakes for marketplace re-entry
The statutory damages award was premised on willful infringement under 15 U.S.C. § 1117(c)(2). Defendants who re-enter the market under new aliases or storefronts — a common pattern after Schedule A cases — risk being identified in supplemental proceedings that Audiowear is expressly authorised to pursue under FRCP 69. The judgment’s alias-collapsing provision compounds this risk.
Audiowear v Partnerships — key questions answered
The Northern District of Illinois entered a default judgment in favour of Audiowear Technology Corporation on 11 March 2025. The court granted a permanent injunction, awarded $10,000 in statutory damages per distinct defaulting defendant for willful infringement of US8491146B2, and ordered eBay and PayPal to freeze and release defendant funds to Audiowear.
US8491146B2 covers audio hats — wearable headwear with integrated audio speaker or headphone components. Audiowear alleged that anonymous online marketplace sellers were manufacturing and selling audio hat products that infringed this patent without authorisation, and brought a Schedule A enforcement action in N.D. Illinois.
Schedule A cases are a patent and trademark enforcement technique where the plaintiff sues a large group of pseudonymous online sellers, often identified only by marketplace store names or aliases listed in a Schedule A attachment to the complaint. Courts in N.D. Illinois regularly handle these cases, which frequently resolve by default judgment when defendants fail to appear.
The court ordered third-party platforms including eBay, PayPal, and Amazon Pay to freeze defendant accounts and transfer funds to Audiowear within seven to fourteen days of the order. This platform-intermediary enforcement mechanism allows patent holders to recover damages even when defendants are anonymous or located outside the US and cannot be directly served.
A defaulting defendant may move to vacate a default judgment under Fed. R. Civ. P. 55(c) or 60(b), but must demonstrate good cause, a meritorious defence, and lack of prejudice to the plaintiff. Given the permanent injunction and asset transfer orders already executed, vacating the judgment would be procedurally complex. The public record does not indicate any defendant has filed such a motion.
