Using PatentIndex

By using this site you agree to these terms. If you do not agree, please do not use it. PatentIndex is offered free of charge and may change or pause features at any time.

Estimates, not legal advice

Scores, status labels, expiry dates, rankings, and every other figure on this site are statistical estimates computed from bulk public data. They are not opinions on a patent’s validity, enforceability, or infringement, and they are not a substitute for a qualified patent attorney or for the official USPTO record. Verify anything you intend to rely on against the official source. The methodology page sets out the known limitations in detail.

Data sources & accuracy

The content is derived from public patent data, including USPTO bulk data and global patent records. We work to keep it accurate and current, but we do not warrant that it is complete, error-free, or up to date. Identity resolution for inventors and organizations is statistical and can merge or split records.

Acceptable use

You may use PatentIndex for personal and professional research. Please do not scrape or place automated load that degrades the service for others, attempt to disrupt or gain unauthorized access to it, or present its estimates as if they were official patent-office records.

No warranty

The site is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including fitness for a particular purpose. Your use of the site is at your own discretion and risk.

Limitation of liability

To the fullest extent permitted by law, PatentIndex is not liable for any indirect, incidental, or consequential damages, or for any decision made in reliance on the information or estimates provided here.

Changes to these terms

We may update these terms from time to time; the date above reflects the latest version, and continued use of the site means you accept the current terms. Questions can go to hello@patentindex.ai.
