Launched on October 3, 2016, the new chemical structure search feature allows users to search for chemical information in patent documents in PATENTSCOPE.
The idea of the chemical structure search is to offer a search feature that:
recognizes the names of chemical compounds in patent texts;
recognizes their structure from embedded drawings in patent texts.
The chemical search applies to the title, abstract, claim and description fields. It only works on developed formulas.
It is currently available for published PCT applications in English and German (from 1978), and the national collection of the U.S. (from 1979). It will become available for other languages and collections in the future.
