Chemistry patents typically represent complex chemical structures represented as Markush structures, which are collections of generic chemical structures with a variety of functional or R groups, ring sizes, atoms, etc. This search recognizes chemical compound names in text and recognizes compound structures in drawings embedded in the text, using both the names of compounds and their structure. STN (Scientific Technical Networks), a collection of more than 200 databases, Chemspider, etc, are some of the main tools for structure searching.

CAS Registry Number (CASRN) is used to search chemical structures based on names or synonyms, known chemical properties, chemical families, molecular formulas, or chemical families. In chemistry, biochemistry, and pharmaceutical engineering, variations in functional motifs and chains enable us to create and identify the most relevant references for inventions, thereby boosting your R&D efforts, impacting legal proceedings, keeping track of the competition, and strengthening your IP rights.
Reports of sequence searches contain citations for the sequences in the literature, information about overlap, length of the sequence, organisms, genes, etc.
