Description

C09J covers adhesive compositions and the chemical/material aspects of adhesive bonding, excluding mechanical application methods. The subclass encompasses adhesives based on various chemical families (synthetic polymers, natural resins, elastomers, inorganic binders), adhesive formulations with specific performance characteristics, and processes for preparing or modifying adhesive materials. It includes novel uses of substances as adhesives and adhesive technologies not classified in other chemical or application-specific sections (such as C09K for sealing or lubricating compositions, or specific end-use classes like textiles or construction).

Filing statistics

IPC subclass C09J recorded 176,125 patent applications worldwide between 2013 and 2023. Annual filings grew from 12,480 in 2013 to 15,115 in 2023 (+21%), peaking at 18,172 applications in 2020. 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).

Glossary

aliphatic radical aliphatic radicals means an acyclic or a non-aromatic carbocyclic carbon skeleton which is considered to be terminated by every bond to: an element other than carbon; a carbon atom having a double bond to one atom other than carbon; an aromatic carbocyclic ring or a heterocyclic ring. use of materials as adhesives means the use of known or new polymers or products as adhesives. rubber rubbers includes: natural or conjugated diene rubbers; or rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for adhesives based on such macromolecular compounds).
