Patent Claims Analyzer
This analyzes patent claims for USPTO compliance before filing, checking antecedent basis errors (like using "said processor" before introducing it with "a/an"), definiteness issues under 35 USC 112(b) (subjective terms like "substantially"), and claim structure problems. It categorizes findings as critical, important, or minor, includes MPEP citations for each issue, and gives you a compliance score. The Python analyzer lives in the skill root and outputs structured JSON you can present as a report. Honestly most useful when you're cleaning up claims before submission or responding to office actions, since it catches the mechanical errors examiners flag routinely. Won't replace a patent attorney's judgment on scope or novelty, but it'll save you from embarrassing antecedent basis rejections.

Patent Claims Analyzer Skill
Antecedent checking is disabled by default. Report it as skipped unless checks_run includes antecedent_basis; retain the reason in checks_skipped. Enabling PATENT_ENABLE_ANTECEDENT_CHECK=1 requires a server restart. Even when enabled, this is a low-confidence pattern check requiring manual review.
Automated analysis of patent claims for USPTO compliance with 35 USC 112(b) requirements.
