Classification Context

Section:: CHEMISTRY; METALLURGY
Class:: ORGANIC MACROMOLECULAR COMPOUNDS; THEIR PREPARATION OR CHEMICAL WORKING-UP; COMPOSITIONS BASED THEREON

Description

Class C08 encompasses the chemistry of organic macromolecular compounds, including their synthesis, chemical modification, and material formulations. This class covers polymers (both natural and synthetic), elastomers, resins, and other high-molecular-weight organic substances, along with their chemical working-up and processing into compositions. It includes subclasses addressing polymer synthesis methods, chemical reactions performed on polymers, cross-linking, blending, and compounding of macromolecular materials for practical applications.

Filing statistics

IPC C08 recorded 1,727,969 patent applications worldwide between 2013 and 2023, summed across its 8 subclasses. Annual filings grew from 130,791 in 2013 to 143,219 in 2023 (+10%), peaking at 176,716 applications in 2017. The most active applicants in class C08 are LG CHEM (14,262 applications), DOW GLOBAL TECHNOLOGIES (12,486 applications) and BASF (BADISCHE ANILIN & SODA FABRIK) (9,858 applications).
