Find Patent Markush Structures

Use a Patent Markush search to find structures (including generic structures) matching your query within patent references.

For example:


The inventor need not have tested or prepared all members of the family, but can make a chemically plausible claim of equivalence via a Markush structure.

A Markush search differs from a substructure search in that it matches the structure query against generic structures found in patents. The result is a list of patent references.



To conduct a Patent Markush search, click the Substances search type. Draw the query using a structure editor, and then check the box for Search Patent Markush.

Click the magnifying glass to submit the query.

Results are displayed on the Patent Markush page.
