Chemical Structure Search

Chemical structure retrieval from the patent and non-patent literature documents is a crucial step for patent analysis. Structure search needs specific skills pertaining searching and retrieving patent information, and interpreting search results. Our chemical structure team has expertise in conducting all types of structure searching using the standard databases such as REGISTRY, CASREACT, CAPLUS, MARPAT, BEILSTEIN etc. hosted by STN.

Our team is experienced in conducting following structures

  • Exact Chemical Structure Search
  • Chemical Substructure Search
  • Markush Chemical Search
  • Chemical Reaction Search
  • Chemical Property Search

Markush Chemical Search


Markush structures are a special representation of the chemical compounds covered in patent documents. Markush structures are complex and highly generic nature which makes even more difficult to index and search than specific chemical structures.

Experts at PatGenix are experienced and well trained to perform precise searches for information retrieval from Markush claims. The reports prepared by our experts provide the necessary and indispensable information to support important business process in chemical companies.

Sequence Search


Searching and analysis of nucleic acid and protein sequence data from patent publications is a challenging task. The bio-sequence information facilitates the R&D process in the pharmaceutical and other life sciences industries.

Our experts perform series of exemplary searches in multiple databases like GENESEQ, CAS REGISTRY/CAplus, PCTGEN, NCBI GenBank, EMBL-Bank and the EBI Fasta databases to retrieve relevant information.
