Zhihuiya Patent Expression Search

This skill searches the Zhihuiya (PatSnap) patent database using an Analytics query expression (e.g. TACD: virtual reality), returning a list of matching patents with their patent IDs and publication numbers, plus the total hit count.

Core Concepts

Expression-based patent search uses Zhihuiya's Analytics query syntax to retrieve patents matching a field-scoped boolean expression. Unlike image-based search, this is a text query against the full patent corpus.

Query expression (queryText) holds an Analytics expression. Common field-scoped syntax:

This skill returns a list of patents (patentId + pn). To retrieve detailed bibliographic data, full text, legal status, family, or images for a specific patent, feed the returned patentId/pn into the corresponding linkfox-zhihuiya-bibliography / linkfox-zhihuiya-simple-bibliography / linkfox-zhihuiya-legal-status / linkfox-zhihuiya-patent-family skills.
