Chemical Structure Search

Finding exact, similar and generic chemical structures for you!

Chemical Structure Search

Chemical structure search is a pivotal process in the fields of chemistry, pharmaceuticals, biotechnology, and various other industries. It involves the identification of chemical compounds that are identical or bear a resemblance to a target chemical structure. This technique plays a crucial role in research and development, facilitating the discovery of new compounds, ensuring compliance with regulatory standards, and aiding in the patenting process. Chemical structure searches are categorized into several types, each serving a specific purpose:

Markush Structure Search

Markush structures represent a powerful tool in the realm of intellectual property, particularly within the chemical, pharmaceutical, and biotechnology industries. These structures enable inventors to claim a broad range of functionally equivalent chemical entities through a single generic representation, thereby simplifying patent applications and protecting a wider array of innovations with fewer documents.


The flexibility of Markush structures comes from their ability to incorporate variations in several aspects, including:

These variations enable a single Markush structure to cover an extensive range of specific compounds, making them invaluable for patent attorneys working in sectors that rely heavily on chemical innovations. Our firm, Mark IP, specializes in identifying the most relevant chemical and Markush structures for our clients, drawing from an extensive database of over 160 million such structures.
