Contains all patent family applications filed at participating IP Offices, along with the dossier, classification, and citation data for these applications. This service also provides Office Action Indicators to help users identify applications that contain office actions, a Collections View for saving documents and applications for review later on in the session, and the ability to download the documents in an application.

Browse the index to find classes and subclasses for different technologies and designs. This is the first place to begin your preliminary patent search.
