Miller Manufacturing Company v. Tractor Supply Company

Background

Plaintiff Miller Manufacturing Company (Miller) designs, manufactures, and sells farm, ranch, and pet products. Defendant Tractor Supply Company (TSC) is a retailer of farm and pet supply products that sells both in physical stores and online, with approximately 349,000 distinct products listed on its website. The parties had a prior business relationship, with TSC selling Miller products for years.

Miller owns several trademarks registered with the United States Patent and Trademark Office, including TROUGH-O-MATIC® (for automatic float valves), PET LODGE® (for portable kennels and automated feeders and waterers), and LITTLE GIANT® (for poultry and stock waterers and stock tanks). In 2024, Miller discovered that TSC's website was using Miller's product images, trademarks, and associated warranties to advertise products made by other vendors — specifically AgraTronix float valves, a Retriever outdoor pet water bowl, and ImPECKables products. Retriever and ImPECKables are TSC-owned trademarks; AgraTronix is a third-party vendor to TSC.

Procedural History

After receiving a customer complaint on November 13, 2024, Miller emailed TSC asking it to remove Miller's product images from the website. TSC took down the offending webpage on November 21, 2024. However, in February 2025, the webpage was reactivated — TSC says by an employee new to their position who did not know the removal was intentional.

In July 2025, Miller discovered additional reposted webpages advertising non-Miller products using Miller content. Miller filed this lawsuit on July 31, 2025, asserting claims for trademark infringement, misleading advertising, patent infringement, deceptive trade practices, and unfair competition. Miller also filed a motion for preliminary injunction shortly thereafter.

In October 2025, the parties stipulated to stay the action pending mediation. TSC agreed to take down all webpages advertising the accused products that were the subject of the preliminary injunction motion, and Miller agreed to withdraw that motion. TSC further agreed not to repost those pages without Miller's approval or court approval. Mediation in February 2026 did not produce a settlement.

After the stay was lifted, TSC sent Miller revised webpages on February 2, 2026, for approval. Miller neither approved nor responded to the revised versions, characterizing the issue as subsumed in broader settlement negotiations. On March 4, 2026, Miller discovered that TSC had again posted three webpages advertising the AgraTronix float valve using Miller content — including downloadable user manuals for LITTLE GIANT® products and a marketing video using the LITTLE GIANT® mark. TSC states that it independently learned of the republication on March 10, 2026, from a third party, removed all Miller content within hours, and fully took down the webpages by March 13, 2026 — five days before Miller filed the present (renewed) motion for preliminary injunction on March 18, 2026.

TSC also submitted evidence of additional safeguards it implemented: deactivating the Stock Keeping Unit (SKU) numbers associated with the accused products, disabling automated website publishing functions, and requiring TSC's legal department to approve any content related to these products before it goes live. TSC explained that when it sourced products from new vendors to replace Miller products, it reused SKUs, which caused Miller content to be included automatically — a technical error it has since identified.

Legal Standard for Preliminary Injunction

A preliminary injunction is an extraordinary remedy that requires the moving party to demonstrate: (1) the threat of irreparable harm; (2) the balance of harms between the parties; (3) likelihood of success on the merits; and (4) the public interest. The court applies the framework from Dataphase Systems, Inc. v. C L Systems, Inc., 640 F.2d 109 (8th Cir. 1981). Irreparable harm — meaning harm that money damages cannot adequately compensate — is a threshold requirement. Loss of intangible assets such as reputation and goodwill can constitute irreparable harm.

The Court's Analysis: Mootness of the Injunction Request

The court began and ended its analysis with the question of mootness — that is, whether the motion had become unnecessary because the challenged conduct had already stopped. The court noted that while a trademark infringement claim is not automatically mooted when a defendant stops using a mark (because past infringement may still give rise to damages), the question here was narrower: whether Miller's request for injunctive relief specifically was moot given TSC's cessation of the allegedly infringing conduct.

The court distinguished this case from prior decisions granting preliminary injunctions after voluntary cessation. In Surdyk's Liquor, Inc. v. MGM Liquor Stores, Inc., 83 F. Supp. 2d 1016 (D. Minn. 2000), the court granted an injunction where the defendant gave no indication it would stop its infringing advertising practices. Here, by contrast, TSC had taken down the webpages, committed not to reactivate them without approval, and implemented structural safeguards. The court also distinguished DF Institute, Inc. v. Marketshare Eds, No. 07-cv-1348, 2007 WL 1589525 (D. Minn. June 1, 2007), where the defendant had admitted that its materials continued to contain allegedly infringing content even after modification. TSC made no such admission here.

The court found that although TSC's removal of the content was not seamless — with two repostings after the initial takedown — the evidence did not demonstrate wrongful intent or a likelihood of continued violations. Each reposting was explained as inadvertent and was corrected promptly upon discovery. The most recent reposting was removed entirely before Miller even filed the renewed motion. The court was sympathetic to Miller's concern that the conduct might recur but concluded that the record did not support a finding that irreparable harm was sufficiently threatened to warrant injunctive relief.

Disposition

The court denied Miller's motion for a preliminary injunction as moot. The court noted that TSC's representation about implementing safeguards was notable, and warned that any future claim of inadvertent reposting would carry far less weight should another incident occur. The underlying trademark and other claims remain pending in the litigation.

Important Notes for Non-Lawyers

Denying the preliminary injunction as moot does not mean Miller lost its case. The court expressly stated that the merits of Miller's trademark claims will be determined at a later stage. The ruling means only that, at this time, a court order telling TSC to stop the conduct is unnecessary because TSC has already stopped — and has made enforceable representations that it will not restart without approval.
