The story
Financial Engines filed US6021397 on December 2, 1997: a computer system that takes an investor's goals and holdings and generates specific portfolio advice without a human advisor in the loop. Betterment and Wealthfront, the startups that popularized the term 'robo-advisor,' launched in 2008 and 2011 — a decade after this filing.
The patent expired on its own twentieth anniversary, December 2, 2017, by which point robo-advisors were already a mainstream product category with billions under management. The foundational patent went quiet without ever becoming a household licensing fight — it simply outlived its own novelty.
The demo below is a 1997-vintage robo-advisor: answer a short goals-and-holdings questionnaire, get an automated allocation, no advisor required — the exact structure the patent claimed, twenty-plus years of term later.

Frequently asked questions
Can I use an expired or public-domain patent?
Once a patent's term ends or it lapses for non-payment, the invention it claimed generally enters the public domain and can be made, used, or sold without a license from the former owner. Separate copyrights, trademarks, or other patents may still apply to a specific product. This is general information, not legal advice.
Is an estimated date the same as a legal ruling?
No. Dates here are computed from public filing data and can differ from a patent's real status in either direction. Confirm against USPTO records before relying on one.
What does a maintenance-fee lapse mean?
US patents require maintenance fees at 3.5, 7.5, and 11.5 years after grant. If the owner stops paying, the patent lapses early and the invention enters the public domain years before its term would otherwise end.
