What problem does it solve? Drafting errors, missed statutory bars, wrong inventorship, and blown deadlines can invalidate a patent application before it is ever examined, and catching them traditionally requires an expensive attorney review. This Skill runs a structured pre-filing audit of a draft U.S. utility patent application against 316 checklist items grounded in 35 U.S.C., 37 CFR, the MPEP, and current USPTO practice, returning a ranked defect list with honest coverage accounting. ## Core Features & Use Cases - Deterministic pre-pass: Python scripts parse the draft (.txt, .md, .pdf, .docx) into a structured fact-pack, run mechanical checks (claim dependency graphs, antecedent-basis candidates, reference-numeral reconciliation, abstract length, fee arithmetic), and compute every deadline with weekend/holiday rollover. - Gated multi-agent review: Sequential gates on patentability, inventorship, and priority halt the audit on blocking failures, then parallel agents review the specification, claims, drawings, and filing packet, with adversarial verification of every fatal finding. - Red-team simulation: Examiner, design-around, and invalidity attack agents stress-test the claims beyond the checklist. - Use Case: An inventor with a draft specification and claims runs the intake questionnaire and pre-pass, receives a ranked report of fatal and serious defects (e.g., a claim term with no antecedent basis, a missed grace-period deadline), and fixes them before paying filing fees. ## Quick Start Use the patent-audit skill to audit my draft patent application in draft.pdf against the pre-filing checklist and report any fatal defects.
