TROs are short-term, emergency measures granted to prevent immediate and irreparable harm before a formal hearing can be held. Their brief duration underscores their role as urgent, provisional remedies in patent disputes.

Temporary restraining orders are designed to provide immediate, short-term relief to prevent ongoing or imminent harm while the court considers a more permanent solution, such as a preliminary injunction.

TROs are typically granted ex parte, meaning they can be issued without the presence or input of the opposing party, to address urgent situations where delay could result in significant harm.

30. How Common Are Injunctions in Cases Involving Standard-Essential Patents (SEPs)?

In 2023, 15% of patent injunctions were granted in cases involving standard-essential patents (SEPs).

SEPs are patents essential to industry standards, and their licensing often involves specific obligations and conditions.

The relatively common occurrence of injunctions in SEP cases highlights the contentious nature of these patents and the need to balance enforcement with fair and reasonable access to standard technologies.


The landscape of patent injunctions is complex and dynamic, reflecting the critical role these legal tools play in protecting intellectual property.

The statistics from 2023 provide a comprehensive overview of how patent injunctions are being utilized across various industries, offering valuable insights into the trends and implications for innovators, businesses, and legal professionals.

The high percentage of injunctions granted in favor of plaintiffs underscores the importance of robust patent protection and the courts’ recognition of the need to prevent ongoing infringement.

Preliminary and permanent injunctions serve as vital mechanisms for stopping infringing activities, with significant durations that can have lasting impacts on the involved parties.
