Upload a USPTO office action or fetch application data directly from USPTO to automatically generate a professional response letter with pre-filled bibliographic data.

Upload a DOCX with tracked changes — insertions become underlined, deletions become strikethrough. Double brackets are used for short deletions per USPTO rules. The modified file downloads automatically.

Upload a markup DOCX — strikethrough text and [[…]] sections are removed, underlines are cleared. The cleaned file downloads automatically.

Upload a patent application DOCX to generate a visual claim dependency diagram, showing which claims depend from which, with warnings for canceled, withdrawn, or incorrect dependencies.
