Corporate Tree Data
Although this is not information that is displayed as part of a patent record, Innovation contains a company thesaurus (or corporate tree) that consists of records of parent and subsidiary company names that are related to one another. This collection is produced by 1790 Analytics, and licensed by Thomson as a patent search aid. It can be used to comprehensively search the US & EP granted patents and EP & WIPO application collections by company, including their name variants and parent/subsidiary company names.[1] This data is updated on a monthly basis, and users can view the date the corporate tree collections were last updated and the date of the next scheduled update through the Collection Coverage & Updates chart.
For example, in the figure below, a searcher opened the corporate tree search to look for subsidiary and/or parent companies in the corporate hierarchy related to the name “Philip Morris.” By using the corporate tree data, the searcher would have been able to see various company names used by Philip Morris in patent searching, from the US, EP and WO/PCT patent collections.
The interface can then be used to select one or more names from the list, which will be automatically transferred to the patent search form, ready to be searched.
Editor's Note:Users should note that while multiple commercial patent search products offer corporate hierarchy lookup tools, the data may be sourced from different producers. While Thomson Innovation contains corporate tree data from 1790 Analytics, products from LexisNexis, such as TotalPatent, contain corporate tree data from the Corporate Affiliations file (sometimes also called DCA, or Directory of Corporate Affiliations), a file produced by LexisNexis. Searchers should be aware that different search products could possibly be querying different corporate databases.
