Featured Highlights

DWPIM - First-ever unified Markush solution delivers comprehensive access to generic chemical structures disclosed in patents

Chemical compounds can be disclosed in patents in two ways: as specific structures and as structures with generic descriptions. These so-called Markush structures may represent hundreds or thousands of individual chemical compounds. Markush structures are widely used in chemical and pharmaceutical patents to protect a class of compounds within a single invention. Therefore, the inclusion of Markush patent searching is decisive for assessing the patentability of a substance or substance class. IP professionals will need this to explore freedom to operate at various stages of the development and also to assess the value of a patent portfolio in the chemical and pharmaceutical field. Pharmaceutical companies in drug discovery use Markush patents for a strong protection of potential drugs. While Markush structures often make up the claims of a patent, specific compounds represent the preferred aspect of the invention.
The Derwent Markush Resource database DWPIM, newly implemented on STN, considerably facilitates chemical patent searching and enables customers to perform more comprehensive searches.

Together with the company InfoChem, Munich, we have developed a Markush search engine specifically designed for handling the data of the Derwent Markush Resources database and in line with the STN standards.
