How this service works
Patent status lookup / legal status / remaining patent life / expiry by patent number. Returns full patent details (title, type, claims, CPC/USPC classes, assignees, inventors, abstract), an estimated ~20-year expiry and years remaining, plus maintenance and citation profile for any US patent ID. For IP and patent agents.
Output
Returns a structured record for the requested patent including its current legal status (active, expired, lapsed), remaining patent life in years, maintenance fee payment history and upcoming due dates, and a citation profile showing forward and backward citations.
Example use cases
Competitive intelligence on rival patents
“Check the status of our competitor's three main patents — US9,234,567, US10,112,889, and US10,456,234. I need to know which ones are still active, how much life is left on each, and whether they've been cited a lot in recent filings.”
Patent portfolio health assessment
“I'm doing a quick audit of our patent portfolio. Can you run through these five patents and tell me which ones are still in force, which ones are expiring soon, which have maintenance fees coming due, and give me a sense of how actively they're being cited in the industry?”
License negotiation due diligence
“We're considering licensing technology from a partner. Before we move forward, can you pull the details on US patent 8,923,456 — specifically whether it's still active, how many years of protection are left, and whether there are a lot of other patents citing it that might create freedom-to-operate issues?”
