What a patent family tree is.
A patent family tree shows related applications that share a priority chain. It can connect an early priority filing to a PCT application, national phases, continuations, divisionals and grants.
The tree is a procedural overview, not a legal opinion. Filing relationships, ownership, status and claim scope should be checked against official records before a legal decision.

Common questions
What is a patent family?
A patent family is a group of related applications and patents that share one or more priority claims.
What is a PCT national phase?
It is an application pursued in a selected jurisdiction from an international PCT application.
What is the difference between a continuation and a divisional?
Both are US descendant applications. A continuation generally pursues the same disclosure, while a divisional is filed for subject matter divided out of the parent.
Can I rely on a family tree for legal status?
Use it as an overview only. Confirm status, ownership, term and scope through official records and appropriate legal review.
