By GleanMark Research Team

5 min read
TESS Search gives you the same structured query capabilities as the USPTO's TESS system — field codes, boolean operators, wildcards, and combinable search steps. Built for practitioners who need precise, examiner-grade control over their queries.
What You Can Do
- Search using 18+ USPTO-style field codes
- Combine multiple search steps with boolean operators (AND, NOT)
- Use wildcards (
*for multiple characters,?for one character) - Build complex queries with parenthetical grouping
- Save and load search sessions
- View a step-by-step audit trail of your search history
How It Works
- Navigate to TESS Search — Click "TESS Search" under Search in the sidebar, or go to
/tess-search - Enter a field code query — Use the format
[field_code] search_term(e.g.,[comb] moonlight AND [ic] 043) - Run the search — Results appear in a paginated table (100 per page)
- Add more steps — Each search creates a step in the audit trail. Combine steps with boolean operators.
- Sort and export — Sort by filing date, registration date, or mark name

([comb] moon) AND [ic] 043 - OR via set operations — run multiple searches separately, then combine results with OR in the step log
*— zero or more characters:moon*matches moonlight, moonbeam, moon?— exactly one character:m??nmatches moon, mean, moan
TESS Search vs Power Search

Tips
- Start broad, then narrow — run a
[comb]search first, then combine with[ic]or[ld]in a second step - Use
[ld] Lto filter to live marks only — removes dead/abandoned marks from results - Save your session if you're building a complex multi-step search — you can reload it later
- Combine with Power Search — use TESS for precision, Power Search for discovery
