Speak in your language.
File a U.S. patent.
Describe the invention naturally in English, Chinese, Spanish, Arabic or French. Pax captures the technical disclosure and prepares the English-language U.S. filing workflow.
- Five-language voice or text intake
- Attorney-supervised paths where required
- Transparent pricing in U.S. dollars
Non-U.S. filings are handled through vetted partner firms; local fees and translation costs are confirmed separately.
