Patent family due diligence tree
This due diligence patent family tree distinguishes live and inactive branches from a common priority filing. It shows a PCT application, a granted US parent with pending and abandoned descendants, a granted EP case, a lapsed Canadian branch and a pending Japanese branch. The status labels help reviewers focus on potentially enforceable or still-prosecuting rights, while preserving the complete procedural family. The drawing does not establish ownership, enforceability, maintenance or claim overlap. Those issues require records and legal analysis. Use the tree as a triage aid for a transaction, freedom-to-operate review or portfolio cleanup. Pair it with a dated status search and an ownership review before conclusions are reached.
