Finds newly expiring design patents and screens related product categories, recalls, and suppliers for private-label opportunities.

Capabilities

Tools

4 tools
category_opportunity_report
PAID (x402, $0.03 USDC on Base). Full off-patent opportunity report for a category slug (see list_categories): every newly-expirable design patent with computed expiry, CPSC recall-safety band, and OFAC/OIG supplier screen, ranked by actionability. Free callers get a preview + x402 challenge.
Input schema 
{'type': 'object', 'required': ['category'], 'properties': {'limit': {'type': 'number', 'description': 'Max candidates (default 25, max 60).'}, 'category': {'type': 'string', 'description': "Category slug, e.g. 'kitchen-gadgets' (from list_categories)."}}}
list_categories
List the private-label product categories Patent-Gap tracks for expiring design patents.
Input schema 
{'type': 'object', 'properties': {}}
newly_expirable
Cross-category feed of design patents that just became (or are about to become) free to make — i.e. fresh off-patent private-label opportunities, soonest-expiry first, already recall- and supplier-screened.
Input schema 
{'type': 'object', 'properties': {'limit': {'type': 'number', 'description': 'Max items (default 30).'}}}
screen_patent
Screen ONE US patent by publication number (e.g. USD689332S1): compute its statutory expiry/status, join CPSC recall-safety for its category, and run an OFAC/OIG screen on the assignee. Returns the freedom-to-operate read (design-patent scope; not legal advice).
Input schema 
{'type': 'object', 'required': ['publication_number'], 'properties': {'category': {'type': 'string', 'description': 'Optional category label to sharpen the recall match.'}, 'publication_number': {'type': 'string', 'description': 'US patent publication number, e.g. USD689332S1 or US8935905B2.'}}}
