Terms of Service
The handshake.
Last updated · May 29, 2026
By using patentbrief.org, you agree to these terms. They're short because the site is a public reading + analysis resource — not a transaction platform. If you don't agree with any of them, simply don't use the site.
Not legal advice
PatentBrief is not a law firm. Nothing on this site is legal advice. Plain-English summaries are written for general education, not to guide decisions about specific patents, products, or disputes. For actual legal decisions, work with a registered U.S. patent attorney.
Accuracy
We work hard to make patent summaries accurate, but patents are technical documents with legal weight, and our summaries are interpretations. We do not guarantee that any specific summary, value estimate, or claim breakdown is correct. Always verify against the official USPTO record before relying on any patent information for commercial decisions.
Tool outputs — including the Patent Value Estimator, Claim Diff, Expiry Calculator, and Claim Explainer — are heuristic. They are educational and exploratory, not professional appraisals or legal opinions.
Your use of the site
You may read, share, link to, and quote PatentBrief content for personal and editorial use. You may not scrape, mirror, redistribute, or train machine-learning models on bulk PatentBrief content without written permission. The underlying patent texts come from the USPTO and remain in the public domain.
No warranty
The site is provided "as is." We make no warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or accuracy. To the maximum extent allowed by law, we are not liable for any damages arising from your use of the site or reliance on its contents.
Intellectual property
The original PatentBrief content — plain-English summaries, design, written editorial, and code — is owned by PatentBrief and protected by applicable copyright. Patent numbers, abstracts, and claims displayed on the site come from the USPTO public record and are not owned by PatentBrief.
Account-related actions
Some features (saving patents, subscribing to alerts, sending feedback) require minimal account-like information. By using those features, you consent to our handling of that information as described in our Privacy Policy.
Changes to these terms
If we change these terms in a way that affects your existing use of the site, we'll update the "Last updated" date at the top of this page. Continued use of the site after changes constitutes acceptance.
Governing law
These terms are governed by the laws of the State of Arizona, United States. Any disputes will be resolved exclusively in the state and federal courts located in Maricopa County, Arizona.
