The USPTO retired TESS in 2023 but their new search tool still lacks the basics: no prosecution history inline, no owner portfolio, no clean filtering. Sealvo fixes that — search 15M records, see full prosecution history on every mark, filter by status/class/owner, view any owner's entire portfolio. Free. No account. No paywall. Built for founders doing pre-filing clearance and lawyers doing due diligence.

Hey PH 👋 I'm Anuradha, and I built Sealvo after getting frustrated with the USPTO's search tools.
The USPTO retired TESS (their old search system) in late 2023 and replaced it with something technically better but still missing the things you actually need: prosecution history inline, owner portfolio view, clean filtering. You end up switching between 3 different tools just to research one trademark.
Sealvo puts it all in one place. Search 15M records, see the full prosecution history, filter by status and class, look up an owner's entire portfolio. Free, no account, instant.
A few things I'm proud of:
— The prosecution history view shows every action ever taken on an application, with dates. No need to go to TSDR separately.
— Owner portfolio: click any owner name to see every trademark they've ever filed across all classes and statuses. Really useful for competitive research.
— The deadline tracking: registered marks show Section 8/9 renewal windows, pending marks show SOU deadlines and office action response windows. All computed from real USPTO data.
I'd genuinely love feedback on:
1. What information is missing that you'd want to see on a mark detail page?
2. Is there a search workflow that feels clunky?
3. What would make you bookmark this over the USPTO search?
