Delphion includes a corporate tree features that accesses corporate hierarchy data from Thomson-owned 1790 Analytics. This data is updated monthly.
The corporate tree feature enhances assignee searching in US, EP and WO/PCT databases. By using corporate data from Thomson-owned company 1790 Analytics, Delphion has included a database of corporate hierarchies into its search form, allowing users to search for company information and discover subsidiary names. This feature allows the user to browse company relationships, and then to select any and all assignee names from the corporate tree feature to query the patent collections. With this feature, users can be more confident that they are searching for the entire IP portfolio represented by IP holdings of each and every branch of a corporate entity.
The corporate tree function can be found next to the assignee search field on the Advanced search form.
Selecting the Corporate Tree link will open a new dialog window. There are two options for the name search: “Original Assignee,” and “Hierarchy.” Original Assignee will display the standardized assignee name assigned to the company by the USPTO, for use with US patents and published applications. Performing a Hierarchy search will display a corporate hierarchy with standard, official names that can be used with confidence in US, EP and WO/PCT assignee searches. Below is an example of a hierarchy search performed on the company name “Sony.”
