About Patents.us
Patents.us is a free US patent search engine built to make the United States patent system easier to explore and understand. We cover more than 7 million patents granted by the United States Patent and Trademark Office (USPTO), and we are continually adding more.
What we offer
- Full-text search across millions of US patents by keyword, inventor, or assignee company.
- Detailed patent pages with the abstract, claims, drawings, classifications, and forward and backward citations for each patent.
- AI-powered plain-English explanations on selected patents, which describe what an invention does and why it matters, alongside a quality assessment.
- Inventor and assignee profiles that aggregate the patents associated with a person or company.
Where our data comes from
All patent records on Patents.us are derived from public bulk data published by the USPTO. US patent documents are public information. We process, structure, and enhance this data to make it more searchable and readable, but the underlying patent records remain the official public record maintained by the USPTO.
Who we are
Patents.us is an independent patent research platform. We are not affiliated with, endorsed by, or connected to the United States Patent and Trademark Office or any government agency.
