C07 ORGANIC CHEMISTRY
Description
C07 encompasses the preparation, purification, and chemical characterization of organic compounds and their intermediates, excluding pharmaceuticals (C07K for peptides/proteins; A61K for drug formulations). This class covers synthetic methods, reactions, and processes for aliphatic, cyclic, aromatic, and heterocyclic compounds, as well as natural product modifications and derivatives. It includes industrial-scale organic syntheses, catalytic processes, and functional group transformations relevant to fine chemicals, agrochemicals, dyes, and polymers.
Filing statistics
CPC C07 recorded 1,699,093 patent applications worldwide between 2013 and 2023, summed across its 8 subclasses. Annual filings grew from 125,486 in 2013 to 135,096 in 2023 (+8%), peaking at 173,344 applications in 2020. The most active applicants in class C07 are ROCHE (12,683 applications), NOVARTIS (10,775 applications) and CHINESE ACADEMY OF SCIENCES (10,619 applications).
