Zhihuiya Patent PDF Downloader
This skill guides you on how to retrieve patent PDF full-text download links from the Zhihuiya patent database, supporting lookup by patent ID or publication number.
Core Concepts
The Zhihuiya Patent PDF service provides direct download links to the full-text PDF documents of patents worldwide. You can query by patent ID or publication number (also called public announcement number), and retrieve up to 100 patents in a single request.
Lookup priority: When both patentId and patentNumber are supplied, the service uses patentId first. This is important to remember when both identifiers are available.
Family substitution: If a patent's own PDF is unavailable, the service can optionally return the PDF of a related family patent instead.
