Diligence That Traces to Prosecution Facts.

Every risk signal, every score, and every red flag ties back to a specific prosecution event — auditable in front of an acquirer or opposing counsel.

One-Click Target Ingest

Enter a company name; pull the full USPTO and EPO estate in one click — documents, metadata, and prosecution history. Bulk sync across PCT, EPO Register, and 100+ international offices via OPS. Diligence starts with a complete prosecution history, not a partial spreadsheet.

Estoppel Exposure

Per §-section: what did counsel argue around versus amend around? Scope surrendered under Festo is flagged directly from the file wrapper. Diligence targets that look strong on the front page can be thin under the amendment chain — and now you can see it.

Litigation & IPR History

Every matter carries a legal-risk layer — pending or resolved district court cases, IPR / PGR petitions, examiner behavior in the same art unit. A target's IPR-magnet patents surface immediately, before you inherit them.

Executive Portfolio Report — One Click to DOCX

Four sections — Action Items, Portfolio Health, Prosecution Activity, and Portfolio Composition — with auto-generated executive highlights. Exports to DOCX. Every claim traces back to a prosecution event. A strong foundation to build a DD memo on, not a substitute for it.
