What you can watch

• A technology: {"term": "solid state battery"} — every new publication touching the topic.
• A company: {"assignee": "Nintendo"} — a competitor's fresh filings, before the tech press writes about them.
• Both: {"term": "lidar", "assignee": "Bosch"} — a company's moves in one specific field.
• A portfolio: up to 20 watches per run via watches, ideal on a weekly schedule.

Use with AI agents (MCP)

https://mcp.apify.com?tools=jdepablos/patent-watch

Your agent gets a "what's new in patents for X?" tool with clean structured output — no PDFs to parse, no pagination. Combine with a scheduled run and the agent can brief you weekly on competitors' R&D.

Pricing

Pay per event: one patent-watch charge per watch that returns hits. Watches with no new publications in the window are never charged — a quiet week costs you nothing.

FAQ

Where does the data come from? Google Patents' public index (worldwide coverage: US, EP, WO, JP, CN…).

How fresh is it? Google Patents indexes new publications with a ~2 month lag. daysBack: 90 is the sweet spot for a rolling watch (below 60 days the index often has nothing yet) — you'll see everything, slightly deferred, with zero API keys or credentials.

Can I filter by jurisdiction? v1 returns worldwide results (the publicationNumber prefix tells you the office: US, EP, WO…). Per-office filters are on the roadmap.

Is this legal advice or a freedom-to-operate search? No. It's a monitoring feed of public data; consult a patent attorney for legal questions.
