Swift Paws, Inc. v. Zhende Tech

Case Overview and Background

The patent infringement lawsuit Swift Paws, Inc. v. Zhende Tech involves a dispute in the growing pet technology and wellness market. The plaintiff, Swift Paws, Inc., is a Florida-based operating company that develops and sells innovative pet enrichment products. Founded in 2012 and gaining prominence after a successful appearance on the television show "Shark Tank," Swift Paws manufactures and markets lure coursing machines—motorized systems that pull a flag or lure along a pulley-guided line for dogs to chase, providing high-intensity exercise. The defendant, Zhende Tech, appears to be a manufacturer of pet products, including leashes, toys, and other supplies, with operations suggesting it is a China-based entity that offers OEM and wholesale services. The lawsuit centers on Zhende Tech's own lure coursing machines, which Swift Paws alleges are copies that infringe upon its patented technology, specifically citing safety features like an "inwardly beveled pulley shield."

The case was filed in the U.S. District Court for the Middle District of Florida, a venue that has historically been considered favorable to patent holders with a high plaintiff success rate and a relatively fast time to trial. Swift Paws is asserting U.S. Patent No. 10,609,904, titled "Lure chasing system," which generally covers a motorized drive unit and pulley system designed to create a continuous loop for a lure line that pets can chase. The procedural posture is particularly notable; the case is assigned to Judge Julie S. Sneed, who granted a preliminary injunction against Zhende Tech on April 3, 2026, forcing it to stop selling the accused products early in the litigation (Dkt. 28). This significant ruling prompted Zhende Tech to file an immediate interlocutory appeal to the U.S. Court of Appeals for the Federal Circuit, where the dispute over the injunction is currently pending (Fed. Cir. Case No. 26-1709).

This litigation is noteworthy as it exemplifies a common pattern of a venture-backed American startup using its intellectual property to defend its market share against what it characterizes as "cheaper 'fake'" products from foreign manufacturers. The case's visibility is amplified by Swift Paws' "Shark Tank" success story. Furthermore, this lawsuit is part of a broader enforcement campaign by Swift Paws, which has filed a similar suit against four other defendants over the same '904 patent in the Middle District of Tennessee, indicating a determined strategy to protect its flagship product line. The outcome of the Federal Circuit appeal on the preliminary injunction will likely have a substantial impact on the competitive landscape for lure coursing equipment. No parallel challenges to the patent's validity at the Patent Trial and Appeal Board (PTAB) are apparent from available dockets.

Key Legal Developments and Outcome

Based on available court records, the litigation between Swift Paws, Inc. and Zhende Tech has moved at an accelerated pace, focusing almost entirely on Swift Paws' request for preliminary injunctive relief. The case is currently stayed at the district court level pending the outcome of Zhende Tech's interlocutory appeal to the Federal Circuit.

A chronological summary of key events follows:

• 2026-01-30: Complaint Filed
  Swift Paws, Inc. filed a patent infringement lawsuit against Zhende Tech and other defendants listed in a sealed schedule in the U.S. District Court for the Middle District of Florida. The complaint alleged that Zhende Tech's lure coursing machines infringed on at least U.S. Patent No. 10,609,904 ("Lure Chasing System"). Swift Paws asserted that the defendants, believed to be foreign entities, were selling infringing products through online marketplaces like Amazon under various aliases, using inferior materials at lower prices, which negatively impacted Swift Paws' revenue and goodwill.

• 2026-03-09: Motion for Temporary Restraining Order (TRO) and Asset Freeze
  Swift Paws filed a verified ex parte motion for a TRO to immediately halt the sale of the accused products and to freeze the defendants' assets. Later that day, Judge Julie S. Sneed granted the motion, entering a TRO against the defendants and requiring Swift Paws to post a $10,000 bond.

• 2026-03-13: TRO Extended
  The court extended the TRO until April 6, 2026, to allow for a hearing on a preliminary injunction.

• 2026-03-30: Evidentiary Hearing on Preliminary Injunction
  The court held an in-person evidentiary hearing on Swift Paws' motion to convert the TRO into a preliminary injunction. Zhende Tech opposed the motion, arguing that the '904 patent was likely invalid for indefiniteness due to terms like "drive window" and "arcuate." It also argued its products did not infringe. The court heard testimony from Swift Paws' CEO, Meghan Wolfgram.

• 2026-04-03: Preliminary Injunction Granted
  Judge Sneed granted Swift Paws' motion, entering a preliminary injunction against Zhende Tech. In her order, the judge found that Swift Paws had shown a substantial likelihood of success on the merits. She determined that Zhende Tech's arguments about indefiniteness and non-infringement were not persuasive at this stage and did not raise a "substantial question" of invalidity or non-infringement. The court was persuaded that the terms in the patent claims could be given their ordinary meanings without the need for formal claim construction.

• 2026-04-08: Interlocutory Appeal Filed by Zhende Tech
  Zhende Tech filed a notice of interlocutory appeal to challenge the district court's order granting the preliminary injunction.

• 2026-04-15: Appeal Transferred to the Federal Circuit
  The appeal was initially docketed incorrectly with the U.S. Court of Appeals for the Eleventh Circuit. On April 15, 2026, an order was issued noting the error and stating the appeal was intended for the U.S. Court of Appeals for the Federal Circuit, which has exclusive jurisdiction over patent case appeals. The case is now pending before the Federal Circuit.

Current Posture: The district court case is effectively paused while the Federal Circuit reviews the preliminary injunction order. No substantive motions regarding claim construction or summary judgment have been filed, and no trial date has been set.

Parallel Proceedings: There is no evidence of any inter partes review (IPR) or other post-grant proceedings challenging the validity of U.S. Patent No. 10,609,904 at the Patent Trial and Appeal Board (PTAB). A search of litigation records indicates Swift Paws has asserted the same patent in a separate lawsuit filed in the Middle District of Tennessee against other defendants, suggesting a broader enforcement strategy.
