## Frequently asked questions

Common questions about our patent license agreement review

- **Q:** What does this patent license agreement review tool check?
  **A:** It identifies the licensed patents and patent applications, the field of use and territory, and whether the grant is exclusive, sole or non-exclusive. It extracts the royalty structure (the royalty base, rate, minimum or running royalties and any upfront or milestone payments), sublicensing rights, who owns improvements and new inventions, patent prosecution and maintenance responsibility, infringement enforcement and defense, and the term and termination provisions.

- **Q:** Will it flag the royalty base and how improvements are owned?
  **A:** Yes. The tool isolates the royalty base (net sales definition, deductions and stacking) and the rate, and separately surfaces the improvements clause so you can see whether enhancements you develop are owned by you, assigned or licensed back to the licensor, and whether grant-backs are exclusive. Both are common sources of value leakage in a patent license.

- **Q:** Does it cover exclusivity, sublicensing and enforcement?
  **A:** Yes. It reports whether the license is exclusive, sole or non-exclusive within the defined field and territory, whether sublicensing is permitted and on what terms, and how patent enforcement works, including who has the right to sue infringers, who controls litigation and how recoveries are shared. It also flags maintenance-fee responsibility so a lapsed patent does not erode your rights.

- **Q:** How long does the patent license analysis take?
  **A:** Most patent license agreements are analyzed in under 30 seconds.

- **Q:** What file formats can I upload?
  **A:** PDF and Word (DOCX) files are both supported.

- **Q:** Is my patent license data secure?
  **A:** Yes. Your document is transmitted over TLS encryption, processed by AI providers under terms that exclude training on your data, and deleted from our servers within 24 hours.
