Patent Family PCT National Phase

Patent family with PCT national phases

This patent family tree starts with a US provisional priority application, then shows the PCT filing and its national-phase entries. The US branch continues to a granted patent, while the EP, Japan and China applications remain pending. The hierarchy represents procedural descent, not technical claim scope. It helps an IP team see which jurisdictions derive from the same priority chain and where prosecution has produced a grant. Use a structure like this for a landscape review, a filing-status summary or a handoff to outside counsel. Confirm application numbers, dates and legal status against the relevant official registers before relying on the diagram for a legal decision.
