New US patents granted to public companies.
About this data
- What it is
- The US Patent and Trademark Office (USPTO) grants new patents every Tuesday. We match the companies named as owners to public companies.
- Who files it
- The USPTO publishes each grant.
- How current
- Grants are published every Tuesday, and we collect them weekly.
- Worth knowing
- A patent count says little about how valuable the patents are. We match owners to companies automatically, so a few may be missed.
All of this comes from public filings.
