Background
Koninklijke Philips N.V. (Philips), a major Dutch technology company, sued Thales DIS AIS USA LLC for infringement of patents related to near-field communication (NFC) technology used in smart cards and identity documents. Philips moved for a preliminary injunction, seeking to halt Thales’s allegedly infringing activities while the litigation proceeded. A preliminary injunction requires the moving party to demonstrate, among other things, that it will suffer irreparable harm if the injunction is denied.
To satisfy the irreparable harm requirement, Philips offered evidence of customer anxiety about the alleged infringement — specifically, concerns from Philips’s customers that dealing with a competing supplier accused of patent infringement could create problems for them in the future. Philips argued these customer concerns demonstrated that it was losing (or at risk of losing) business relationships and goodwill. The district court denied the preliminary injunction, finding that the harm Philips demonstrated was too speculative. Philips appealed.
The Court’s Holding
The Federal Circuit affirmed. The court held that to establish irreparable harm sufficient to support a preliminary injunction, the patent owner must produce concrete evidence of actual or imminent harm — not speculative fears or hypothetical future consequences. Customer expressions of generalized concern about the litigation, without more, do not demonstrate that Philips was actually losing business, losing customers, or suffering quantifiable harm to its competitive position.
The court emphasized that irreparable harm must be likely, not merely possible. Mere expressions of customer discomfort or concern about the legal dispute do not establish that the patent owner is losing sales, market share, or long-term business relationships. Without evidence linking the alleged infringement to actual, concrete business consequences — such as lost contracts, diverted sales, or documented customer defections — the irreparable harm showing falls short. Speculative harms that depend on a chain of uncertain future events do not satisfy the standard.
Key Takeaways
- Irreparable harm for purposes of a preliminary injunction must be demonstrated with concrete evidence of actual or imminent injury — not speculation or customer concerns about potential future consequences.
- Customer anxiety or discomfort about a competitor’s patent infringement does not, by itself, establish that the patent owner is losing business or suffering harm that cannot be compensated by money damages.
- Patent owners seeking preliminary injunctions must document specific, concrete harms: lost sales, diverted contracts, customer defections, or reputational damage that can be traced directly to the alleged infringement.
- The irreparable harm requirement continues to be a significant hurdle for patent preliminary injunctions in the Federal Circuit, particularly in commercial contexts where money damages can eventually compensate for lost business.
Why It Matters
Preliminary injunctions are a powerful tool in patent litigation, capable of immediately halting a competitor’s sales and disrupting supply chains while the case proceeds. But because of their severity, courts apply a demanding standard — and the irreparable harm requirement is often the most difficult element for patent owners to satisfy after the Supreme Court’s eBay decision in 2006 abolished any presumption of irreparable harm from patent infringement.
The Philips v. Thales decision reinforces that standard: patent owners who want preliminary injunctions must bring concrete evidence of real-world harm, not general anxiety about the legal dispute. For companies in high-stakes patent disputes involving technology that is embedded in customer supply chains or government contracts — as NFC technology in identity documents often is — building a strong irreparable harm record from the outset of the litigation, with documented evidence of actual business impact, is essential to pursuing preliminary relief effectively.
