Description

Class C09 encompasses colorants, protective coatings, surface treatments, and binding materials used across manufacturing and construction industries. It covers dyes for textiles and other substrates, paints and varnishes, polishes, natural and synthetic resins, adhesives, and sealants, along with their formulations and application methods. This residual class also captures chemical compositions and material applications that do not fit within more specialized chemical classifications, serving as a catch-all for coating and adhesive technologies not addressed elsewhere in the chemistry scheme.

Filing statistics

IPC C09 recorded 804,439 patent applications worldwide between 2013 and 2023, summed across its 8 subclasses. Annual filings grew from 63,751 in 2013 to 63,498 in 2023 (+0%), peaking at 82,200 applications in 2018. The most active applicants in class C09 are LG CHEM (6,420 applications), NITTO DENKO CORPORATION (5,752 applications) and HALLIBURTON ENERGY SERVICES GROUP (5,650 applications).
