Check a patent draft before filing

Upload a text-based PDF or DOCX. Get review cues for numbered claim references, obvious antecedent phrasing, and abstract length, with links to the USPTO guidance behind each check.

This is a limited text screen, not a patent examination, filing review, legal opinion, or guarantee of acceptance. Drawing reference numerals, sheet formatting, and legal sufficiency need human review.

Up to 5 MB. The text is processed for this check, not stored as a filing. Avoid uploading client-confidential material without authority. Text-based files only; drawings and scans need manual review.

Need help? Read the provisional patent application guide or find a USPTO-registered patent practitioner.
