Description
C07H encompasses the chemistry of monosaccharides, disaccharides, and polysaccharides, along with their synthetic derivatives and chemical modifications. This subclass also covers nucleosides (sugar-base conjugates), nucleotides (phosphorylated nucleosides), and nucleic acids (DNA, RNA, and analogues), including their isolation, synthesis, and structural characterization. The classification includes oligonucleotides, modified nucleotides, and sugar-nucleoside conjugates used in therapeutic, diagnostic, or research applications. Adjacent carbohydrate chemistry not involving nucleoside/nucleotide components falls under C07C or C07G.
Filing statistics
CPC subclass C07H recorded 52,989 patent applications worldwide between 2013 and 2023. Annual filings declined from 4,044 in 2013 to 3,646 in 2023 (-10%), peaking at 5,643 applications in 2018. The most active applicants in class C07 are ROCHE (12,683 applications), NOVARTIS (10,775 applications) and CHINESE ACADEMY OF SCIENCES (10,619 applications).
