In practice, the far more common way a patent dies is a missed maintenance fee. In the US, utility patents require fees at 3.5, 7.5, and 11.5 years; miss the standard window and the surcharge window, and the patent lapses; reviving it is costly and far from guaranteed. Other jurisdictions charge annual annuities that compound the tracking burden. The expiration date is fixed and decades away; the fee windows are recurring, near-term, and unforgiving. A patent reminder that only tracks the 20-year term misses the deadlines that actually matter. ### When a lapsed patent takes the royalty stream with it Patents rarely sit in isolation. They back licensing deals, secure exclusivity in a market, and underpin valuations in fundraising and M&A. When a patent lapses on an unpaid fee, the licensing royalties tied to it can evaporate, competitors gain freedom to operate, and the asset disappears from the portfolio overnight. The cost of the missed fee is trivial; the cost of the lapse is the asset itself. Tracking each maintenance window as a distinct, owned reminder (separate from the distant expiry) is what protects the value the patent was filed to create. ## Quick answers Short answers to the questions we get most about reminder extraction. - **Q:** How does the patent expiration reminder work? **A:** Upload your patent grant, IP assignment, or licensing agreement as a PDF or DOCX. We run an AI extraction on the document, find the patent term and expiration date, maintenance fee windows, annuity deadlines, and any licensing obligations tied to the patent, and suggest reminder dates for each. You can then start a free Contracko trial to track everything automatically, or note the dates yourself. - **Q:** Does it track maintenance fees and annuities? **A:** Yes, these are the deadlines that actually let patents lapse. US utility patent maintenance-fee windows open at 3.5, 7.5, and 11.5 years after grant, each with a six-month surcharge window after the standard window. Many jurisdictions charge annual annuities instead. The tool surfaces the schedule it finds in the document so you can set a reminder ahead of each window. - **Q:** What happens after the extraction? **A:** You'll see a list of suggested reminders pulled from your document, each anchored to the clause or schedule it came from. From there you can start a free Contracko trial to track them automatically with email alerts and owner assignments, or just note the dates yourself if that's all you need. - **Q:** Can it handle a portfolio of patents? **A:** The free tool reads one document at a time. If you manage a portfolio, a Contracko trial lets you upload each patent and keep every maintenance fee window, expiration date, and license obligation in one tracked view, so a single missed fee never slips through. - **Q:** What happens to my contract after I upload it? **A:** Your document is transmitted over TLS encryption and processed by AI providers under terms that exclude training on your data. If you start a Contracko trial, the file moves into your private workspace and stays there. ## Other reminder pages Each page is tuned to a different contract type or reminder job. ### [Contract expiration reminder tool](https://contracko.com/contract-reminder-tools/contract-expiration-reminder-tool) ### [NDA expiration reminder](https://contracko.com/contract-reminder-tools/nda-expiration-reminder) ### [Trademark expiration reminder](https://contracko.com/contract-reminder-tools/trademark-expiration-reminder) ### [Music license renewal reminder](https://contracko.com/contract-reminder-tools/music-license-renewal-reminder) ### [Franchise agreement renewal reminder](https://contracko.com/contract-reminder-tools/franchise-agreement-renewal-reminder) ### [Contract obligation reminder tool](https://contracko.com/contract-reminder-tools/contract-obligation-reminder-tool) [Browse all reminder tools](https://contracko.com/contract-reminder-tools) ## Keep every patent in force Track maintenance fee windows, annuity deadlines, and expiration dates across your whole portfolio.
