Returns status of each data source including: - Configuration status (API keys, credentials) - Connection availability - Rate limit information where available

Look up CPC (Cooperative Patent Classification) code information. USE THIS TOOL WHEN: You need to understand what technology area a CPC code represents, or find related classification codes. Args: cpc_code: CPC code to look up (e.g., "G06" for computing, "G06N3/08" for neural networks) Returns: Classification details including section, title, and description. For section codes (A-H, Y), returns subsection list.

Look up USPTO application status code meaning. USE THIS TOOL WHEN: You encounter a status code in application data and need to understand what examination stage it represents.

Search granted US patents in Patent Public Search (ppubs.uspto.gov). USE THIS TOOL WHEN: You need full-text search of US patents with daily updates, or need access to the most recent patent filings. PREFER OVER patentsview_search WHEN: You need the most current data (PPUBS updates daily vs PatentsView periodic updates). Args: query: Search query using USPTO syntax. Examples: - "machine learning" - searches all fields - TTL/"neural network" - title contains phrase - IN/Smith AND AN/IBM - inventor Smith, assignee IBM - CPC/G06N3/08 - CPC classification offset: Starting position for pagination (default: 0) limit: Maximum results to return (default: 100, max: 500) sort: Sort order (default: "date_publ desc") Returns: Normalized response with patent results including GUID, title, abstract, dates, inventors, and classification codes.

Search published US patent applications in Patent Public Search. USE THIS TOOL WHEN: You need to search pre-grant published applications (applications publish 18 months after filing, before grant). Args: query: Search query using USPTO syntax (same as ppubs_search_patents) offset: Starting position for pagination (default: 0) limit: Maximum results to return (default: 100, max: 500) sort: Sort order (default: "date_publ desc") Returns: Normalized response with application results.

Guide for conducting a comprehensive prior art search. USE THIS PROMPT WHEN: You need to find existing patents and publications relevant to an invention for patentability assessment or invalidity analysis.

Guide for analyzing patent validity and prosecution history. USE THIS PROMPT WHEN: You need to assess the strength and validity of a patent by reviewing its prosecution history and any challenges.

Guide for analyzing a company's patent portfolio. USE THIS PROMPT WHEN: You need to understand a competitor's IP position, technology focus areas, and patent strategy.

Guide for researching PTAB proceedings (IPR/PGR/CBM). USE THIS PROMPT WHEN: You need to research Patent Trial and Appeal Board proceedings, decisions, and outcomes for validity challenges.

Guide for freedom-to-operate (FTO) analysis. USE THIS PROMPT WHEN: You need to assess patent infringement risk for a product or technology before commercialization.
