AboutWhat Is Chemical Structure-based Search?

Chemical Structure-based Search involves identifying patents and scientific publications containing chemical compounds structurally similar to or matching your compound of interest. Instead of relying solely on keywords or textual descriptions, this search examines molecular structures, substructures, and Markush representations, providing a far more comprehensive and reliable view of prior art.

Such searches are critical for:

  • Patentability assessments before filing a patent application
  • Freedom-to-operate (FTO) analyses to avoid infringement risks
  • Patent opposition and invalidation proceedings
  • Research and development planning for new formulations or molecules

Whether you are a pharmaceutical companychemical manufacturer, or biotech innovator, our structure-based searches provide you with the clarity needed to make confident IP and R&D decisions.

Substructure and Similarity Searching

Through substructure, similarity, and Markush searches, we identify compounds that are identical, closely related, or functionally similar to your query molecule.
