Email/webhook alerts on patent-application status changes (office actions, allowances), pitched at applicants and small firms after USPTO retired its PEDS API.
“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 PEDS retirement created real developer disruption (forum threads from tools that broke), suggesting a refugee moment. The refugee framing failed verification: displaced users convert to USPTO's free replacement API, not to a paid intermediary.
The primary buyer already gets this free from the source: USPTO's e-Office Action program has emailed applicants and their attorneys on office-action issuance for over a decade — this is not a future risk, it is a decade-old fact that kills the core use case at $0. Above that, the third-party patent-docketing shelf has 12+ incumbents with free low-end tiers. The measured shelf agrees: an existing Apify USPTO-monitor actor had 3 users. An API deprecation where the agency ships a free replacement API is not a business opportunity; it is a weekend migration.
USPTO discontinuing the free e-Office Action email program — an agency walking back a decade-old free service to its primary constituents. Price that probability honestly before building.
