Alerts when patents lapse for non-payment of maintenance fees, sold to competitors, licensing scouts, and generic manufacturers.
“Market-tested” means a real shipped product or experiment measured the failure directly (a live user count, a dead auction, a documented shutdown). “Predicted” means the verdict is an evidence-based forecast from the receipts below, not a direct measurement.
The information has real users — freedom-to-operate analysts and generics manufacturers do track lapses. But demand evidence for a standalone alert product was weak (inference from workflows, not observed purchases of alerting alone), and the history below explains why.
The 'nobody sells change-alerts' premise is simply false in patents: lapse and status alerting is a standard bundled feature of every patent platform (PatSnap, PatSeer, Minesoft) — no serious buyer needs a separate tool. Below the platforms, tiny self-serve services already sell monitoring for as little as ~$2/patent/month. And the graveyard has a headstone with your product's name on it: patentalert.com ran this exact standalone model and is dead (visible in the Internet Archive). The buyers who care are inside platforms; the buyers who are not inside platforms do not care enough to pay.
Major patent platforms unbundling alerting into a separately-priced tier would recreate a standalone market. Platforms bundle it precisely because it is cheap to ship and high-retention — expect this roughly never.
