USPTO Patent Grants — Weekly Grant Data API
Pricing
from $100.00 / 1,000 uspto patent records
Pull USPTO weekly patent-grant records in bulk. Clean JSON for IP counsel, brand teams and AI agents.
Free-text keywords to search across patent title + abstract. Each keyword becomes an OR clause. Examples: ['machine learning'], ['neural network', 'transformer'], ['CRISPR', 'gene editing'], ['battery', 'lithium-ion']. Leave empty to pull all newly granted patents in the date window (use date_range + cpc_class to narrow). Multi-word phrases are treated as exact phrases.
[]Restrict results to patents granted to a specific assignee (company / institution). Matches partial names, case-insensitive. Examples: 'Apple', 'Google', 'NVIDIA', 'IBM', 'MIT', 'Stanford'. Leave blank to include all assignees. Useful for competitive intelligence — monitor a specific competitor's filing cadence.
Filter by USPTO grant date (the date the patent was officially issued, not the application or priority date). 'today' = patents granted today only (USPTO publishes grants every Tuesday); 'week' = trailing 7 days; 'month' = trailing 30 days; 'year' = trailing 365 days; 'all' = no date filter (search the full Google Patents index).
Cooperative Patent Classification (CPC) symbol to filter by. Use either the 1-letter section (e.g. 'G' = Physics / G06 = Computing), the 4-character class (e.g. 'G06N' = AI/ML systems, 'H04L' = digital comms, 'A61K' = pharma compositions), or a full subgroup (e.g. 'G06N3/08' = neural-net learning methods). See cpc-tooltip below. Leave blank for any class.
If true, return only patents flagged as AI / ML related. We mark a patent AI-related when its title or abstract contains terms like 'machine learning', 'neural network', 'deep learning', 'transformer', 'reinforcement learning', 'LLM', 'large language model', 'generative AI', 'natural language processing', 'computer vision', or when its CPC code is G06N (Computing arrangements based on specific computational models). Useful for AI VCs, AI M&A diligence, and competitive intelligence on AI labs.
Maximum number of patent grant records to push to the dataset. The Google Patents result page returns up to 100 patents per page; we'll auto-paginate to satisfy your limit. Typical IP-monitoring workflows pull 50-500 records per refresh. For a full daily competitive-intel sweep set to 1000+.
If true, fetches each patent's detail page after the search to populate claims_count, full CPC class list, citations_count and a longer abstract excerpt. Doubles run time (one extra HTTP request per patent) but produces a far richer record. Recommended for IP / legal due-diligence workflows. If false, only fields available from the search-results JSON are emitted.
