Patent Legal Status Checker
Queries Zhihuiya (PatSnap) to determine the legal standing, validity, lifecycle stage, and event history of any patent.
The Patent Legal Status Checker skill enables Claude Code to query the Zhihuiya (PatSnap) database to verify the current legal standing, validity, and event history of patents by ID or publication number. It delivers a comprehensive three-layered overview encompassing high-level status (active, inactive, pending), detailed lifecycle stages (granted, expired, revoked, withdrawn), and specific legal events such as transfers, licenses, pledges, oppositions, and litigations. This skill is indispensable for e-commerce sellers, product researchers, and IP analysts assessing patent infringement risks, verifying competitor intellectual property, or evaluating product freedom-to-operate before launching on marketplaces like Amazon, TikTok Shop, or Shopify.
