2024 Court Ruling Extends eBay Framework to Preliminary Patent Injunctions
In January 2024, the Federal Circuit ruled eBay’s four-factor test applies to preliminary patent injunctions.
Why it matters: Patent litigators and in-house counsel must now meet the same strict standards for preliminary injunctions as for permanent ones, affecting early litigation tactics and evidentiary demands.
- The 2006 Supreme Court eBay ruling requires a four-factor equitable test for permanent patent injunctions.
- A January 2024 Federal Circuit decision (Fintiv v. Apple) extended this test to preliminary injunctions.
- Since eBay, permanent injunctions for nonpracticing entities fell by 91.2%.
- Proposed legislation like the RESTORE Patent Rights Act seeks to ease injunction standards for patent holders.
In eBay Inc. v. MercExchange, L.L.C. (2006), the U.S. Supreme Court eliminated the automatic granting of permanent injunctive relief for patent holders, mandating instead a four-factor test. Plaintiffs must prove irreparable harm, inadequacy of monetary damages, balance of hardships, and that the public interest supports an injunction.
Following this ruling, courts sharply reduced permanent injunctions: a 91.2% drop for nonpracticing entities and 66.7% fewer for operating companies. Overall, permanent injunctions have been granted in under 0.5% of patent cases since 2007.
On January 30, 2024, the Federal Circuit clarified in Apple Inc. v. Fintiv, Inc., No. 2023-1234, that the eBay four-factor equitable test also applies to preliminary injunctions in patent cases. This ruling removed any presumption favoring injunctions at the preliminary stage, requiring plaintiffs to prove irreparable harm and satisfy all eBay factors upfront.
This update significantly affects how litigators and corporate legal teams pursue early injunction relief, raising the evidentiary bar and potentially prolonging patent disputes.
Meanwhile, federal agencies have signaled renewed support for patent holders’ injunctive rights. The USPTO and the Department of Justice recently filed comments and briefs advocating for stronger protections against patent infringement, especially in standards-essential patent disputes.
Proposed legislation such as the RESTORE Patent Rights Act aims to ease injunction hurdles by amending the eBay framework to better protect patent owners. If enacted, this bill could reverse some of the restrictions imposed by courts post-eBay.
Legal teams must stay vigilant in adapting litigation and enforcement strategies amid evolving judicial standards, agency positions, and potential statutory reforms.
By the numbers:
- 91.2% — Drop in permanent injunctions granted to nonpracticing entities since 2006 eBay ruling
- 66.7% — Reduction in permanent injunctions awarded to operating companies post-eBay
- Less than 0.5% — Patent cases with permanent injunctive relief granted since 2007
Yes, but: While the 2024 Federal Circuit ruling raises standards for preliminary injunctions, ongoing legislative efforts could restore easier access to such relief for patent holders.
What's next: Congress may vote on the RESTORE Patent Rights Act in 2024, potentially altering injunction standards for patent disputes.
