C13 SUGAR INDUSTRY
Description
C13 covers the production, processing, and refining of sugars and sugar products from natural sources, primarily sugar cane and sugar beets. This includes extraction methods, crystallization, purification, and concentration processes, as well as the manufacture of molasses, syrups, and related by-products. The class encompasses equipment, apparatus, and chemical treatment techniques specific to sugar manufacturing operations. Related fermentation processes and uses of sugar in other chemical industries are classified elsewhere (e.g., C12 for fermentation biotechnology, C07 for organic chemical synthesis).
Filing statistics
CPC C13 recorded 7,975 patent applications worldwide between 2013 and 2023, summed across its 2 subclasses. Annual filings declined from 1,084 in 2013 to 298 in 2023 (-73%), peaking at 1,121 applications in 2014.
