GoClips v. Xiamen Aoyin: Default Judgment & Permanent Injunction in Sink Clip Patent Case

Introduction

In a decisive outcome for a U.S. patent holder facing foreign competition, the U.S. District Court for the Northern District of Georgia entered a final default judgment and permanent injunction against Xiamen Aoyin Industry & Trade Co., Ltd. in the matter of GoClips, LLC v. Xiamen Aoyin Industry & Trade Co., Ltd. (Case No. 1:25-cv-00378). The ruling, issued on March 3, 2026, by Chief Judge Eleanor L. Ross, permanently bars Xiamen Aoyin and its affiliates from manufacturing, importing, selling, or distributing its “Sinkits Sink Clamps” product line in the United States.

At the center of this construction hardware patent infringement dispute is U.S. Patent No. 9,828,754 — a patent protecting innovative sink clip fastening technology. The case closed just 399 days after filing, underscoring the efficiency of default proceedings when foreign defendants fail to appear. For patent holders, IP counsel, and R&D professionals operating in the hardware and fixture space, this ruling offers valuable strategic insights into cross-border enforcement and the power of permanent injunctive relief.

Case Overview

The Parties

The Patent at Issue

This landmark case involved U.S. Patent No. 9,828,754 (Application No. 14/566,112), covering fastening and clamping technology applicable to sink installation — a component used in countertop and undermount sink mounting systems. Sink clips are critical mechanical fasteners that secure sinks to countertops from beneath, and proprietary designs in this space carry meaningful commercial value in both residential and commercial construction markets.

The Accused Product

The accused infringing product is the “Sinkits Sink Clamps” — a clamping device line sold by Xiamen Aoyin under its Aoyin Tools brand. GoClips alleged the product directly infringed the claims of US9828754 through its manufacture, importation, offer for sale, and distribution in the United States.

Legal Representation

GoClips was represented by Charles G. Geitner and Vincent C. Bushnell of Pierson Ferdinand, LLP. No defense counsel entered an appearance on behalf of Xiamen Aoyin.

Litigation Timeline & Procedural History

GoClips filed its complaint in the U.S. District Court for the Northern District of Georgia on January 28, 2025. Venue selection in the Northern District of Georgia is strategically notable — the court has an established IP docket and Chief Judge Eleanor L. Ross presided over this matter through final resolution.

Xiamen Aoyin failed to respond to the complaint within the required timeframe, triggering the default process. GoClips’ counsel subsequently filed a Motion for Final Default Judgment, supported by pleadings, exhibits, and legal arguments. Judge Ross conducted a consideration of the full record before granting the motion.

The case resolved entirely at the first instance/district court level without appeal, trial, or inter partes review proceedings. The 399-day duration reflects the procedural steps required to properly perfect default judgment under federal rules — including proper service on a foreign defendant — rather than contested litigation delay.

The Verdict & Legal Analysis

Outcome

Chief Judge Eleanor L. Ross granted GoClips’ Motion for Final Default Judgment on March 3, 2026, entering final judgment in favor of GoClips, LLC on all claims asserted in the original complaint. The specific damages award amount was not disclosed in the publicly available case data. Most consequentially, the Court issued a permanent injunction — one of the most powerful remedies available in patent litigation.

Scope of the Permanent Injunction

The injunction is notably broad in its coverage. It permanently restrains:

• • Xiamen Aoyin Industry & Trade Co., Ltd. d/b/a Aoyin Tools
• • Its affiliates, agents (specifically naming agent Serena Meng), servants, employees, officers, and directors
• • Anyone acting in privity with or on behalf of Xiamen Aoyin

Prohibited activities encompass the full commercial lifecycle of the infringing product: manufacture, importation, use, sale, offer for sale, and distribution of the “Sinkits Sink Clamps” in the United States. This comprehensive injunctive language is designed to prevent circumvention through related entities or personnel changes.

Verdict Cause Analysis

This case proceeded as a straightforward patent infringement action under 35 U.S.C. § 271. Because Xiamen Aoyin failed to appear or defend, the Court accepted GoClips’ well-pleaded allegations as admitted pursuant to default judgment standards. GoClips’ attorneys successfully built a record sufficient to satisfy the Court on both liability and the appropriateness of permanent injunctive relief — the latter requiring demonstration of irreparable harm, inadequacy of monetary damages, balance of hardships, and public interest considerations under the eBay Inc. v. MercExchange four-factor framework.

The explicit naming of agent Serena Meng in the injunction is a strategically significant detail. Courts include named individuals in injunctions to prevent corporate dissolution or restructuring as a tactic to circumvent court orders — a known pattern in cross-border enforcement cases.

Legal Significance

While default judgments carry limited direct precedential value on substantive patent law questions (as no claim construction or validity determination was litigated), this ruling is significant for several reasons:

1. Enforcement against Chinese manufacturers distributing products on U.S. platforms remains an active and growing area of patent litigation strategy
2. The breadth of injunctive language — covering importation explicitly — demonstrates courts’ willingness to address the full supply chain in hardware patent cases
3. The case reinforces that U.S. patent holders can obtain meaningful relief even when defendants default, provided proper procedural steps are followed

Strategic Takeaways

For Patent Holders: Proactive enforcement through U.S. district courts remains viable against non-appearing foreign defendants. Building a thorough evidentiary record — even in default proceedings — is essential to securing broad injunctive relief. Consider naming known agents or representatives in complaints to preserve options for injunctive scope.

For Accused Infringers: Failure to appear in U.S. patent litigation results in adverse judgment on all claims. Foreign manufacturers selling into U.S. markets through e-commerce channels face real enforcement risk and should engage U.S. patent counsel upon receiving service of process.

For R&D Teams: Products distributed under private labels or third-party brand names (here, “Sinkits”) can still be traced to manufacturers for infringement purposes. Freedom-to-operate (FTO) analyses should account for fastening and clamping patent portfolios, including utility patents covering hardware fixture components like US9828754.
