Robert Bosch LLC v. Pylon Manufacturing Corp.

Section 1292(a)(1) directly authorizes appeals from interlocutory orders granting or refusing injunctions, and § 1292(c)(1) gives the Federal Circuit exclusive jurisdiction over such patent-case appeals. Because the district court expressly denied Bosch's motion for a permanent injunction, the order fell squarely within those provisions.

The additional requirements from Carson v. American Brands apply only when a party appeals an order that does not expressly grant or deny an injunction but allegedly has that practical effect. They do not limit appellate jurisdiction over an order that explicitly refuses injunctive relief.

Under eBay, a successful patentee must satisfy the traditional four-factor equitable test: irreparable injury, inadequacy of legal remedies, a favorable balance of hardships, and consistency with the public interest. Courts may not use categorical rules or shortcuts that effectively replace that individualized inquiry.

Although the patent right to exclude remains important to the equitable analysis, it cannot by itself justify an injunction. At the same time, eBay did not create a rule against injunctions: the history of protecting practicing patentees against infringing competitors remains relevant when courts apply the four factors to the particular facts.

The district court gave improper weight to the presence of other competitors. A two-supplier market can support an inference that an infringer's sales displace the patentee's sales, but the converse does not follow. Other market participants do not negate irreparable harm, particularly where Bosch had consistently enforced its patents against other alleged infringers.

The court also erred by treating the wiper-blade business as non-core to Bosch's overall enterprise. Whether an injury is irreparable does not turn on the share of a company's total business represented by the infringed product line; otherwise, the result would irrationally depend on how a company organized its corporate affiliates.

The undisputed record showed that Bosch and Pylon competed in every relevant distribution channel. Both pursued Wal-Mart, both sold to or competed for automotive specialty retailers, and Pylon had sold or sought to sell beam blades to original equipment manufacturers. Bosch's lack of a current beam-blade sale to a particular channel did not mean it was not competing there.

Bosch introduced unrebutted evidence that Pylon's infringement caused lost market share, loss of access to potential customers, and price erosion. Pylon's acquisition of the Wal-Mart account was substantial circumstantial evidence of lost market share, and Bosch's product-management testimony explained how losing Wal-Mart made it harder to win other mass-merchandiser accounts.

Bosch also produced public evidence that Pylon and its parent faced financial stress and might not satisfy a damages judgment. Because damages discovery had been bifurcated at Pylon's request, Pylon controlled the most relevant financial information; yet it offered no evidence or assurance that it could pay past damages or a prospective royalty. This unrebutted evidence further supported irreparable harm.

Money damages could not fully compensate Bosch for continuing loss of market share, customer opportunities, and price erosion. Pylon's questionable ability to pay made a damages remedy even less meaningful, because a remedy at law cannot be considered adequate without considering whether the infringer can actually satisfy it.

The balance of hardships favored Bosch. Pylon could not avoid an injunction merely because it was smaller than Bosch or because wiper blades were its principal business; a party that builds its business around an infringing product cannot complain that an injunction threatens that business. Bosch, by contrast, faced the substantial hardship of having to compete with its own patented technology.

Neither side established a concrete public-interest reason for or against an injunction. Bosch's safety assertion lacked record support, while the parties' general invocations of patent exclusion and competition did not resolve the factor. The factor was therefore neutral rather than dispositive.

Ordinarily, the district court should weigh equitable factors in the first instance. But here, the parties and the court had already proceeded under eBay, the evidence conclusively favored Bosch, and a further remand would only delay relief while Pylon continued infringing. The Federal Circuit therefore reversed and remanded with instructions to enter an appropriate injunction.
