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