A curated feed of freshly dead/abandoned trademarks for brand-name hunters, modeled on expired-domain drop lists.
“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.
Honest answer: none that survived verification. The idea is an analogy to expired-domain feeds (a real, monetized market) — but no off-platform evidence of anyone paying for dead-trademark discovery was found. The shelf is empty because buyers are absent, not because nobody thought of it.
The domain analogy breaks structurally. Expired domains monetize because domains are exclusive, instantly registrable, and winner-take-all at the moment of drop — a race worth paying to win. Dead trademarks have none of that: rights flow from use, common-law rights persist after registration lapses, and 'abandoned' marks are frequently revivable or still legally encumbered — so 'up for grabs' is legally overclaimed. Meanwhile USPTO's own free tools (TSDR status lookups, full bulk data downloads) put the raw-data price at $0 for anyone technical enough to care. No urgency, no exclusivity, no buyer: a feed of things nobody is racing to claim.
Observed purchase behavior — for example, brand agencies documented paying researchers for abandoned-mark sweeps — would reopen the question. A legal change making lapsed marks cleanly claimable (creating the race dynamic) would too, but no such change is plausible.
