PREPARATION OF GLUE OR GELATINE

Description

C09H covers the manufacturing and preparation processes for adhesive glues and gelatine materials derived from natural sources, such as animal proteins and collagen. The classification encompasses extraction methods, purification techniques, chemical treatment, and formulation of glue and gelatine products intended for industrial and commercial applications. This includes processing of raw materials into finished adhesive products and gelatine for use in various industries including packaging, textiles, food, and pharmaceuticals. The subclass excludes synthetic adhesives and polymeric binders, which are classified elsewhere in the adhesives hierarchy.

Filing statistics

IPC subclass C09H recorded 438 patent applications worldwide between 2013 and 2023. Annual filings grew from 34 in 2013 to 41 in 2023 (+21%), peaking at 51 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).

Glossary

Glue Glue is an adhesive, or glue, is a mixture in a liquid or semi-liquid state that adheres or bonds items together. Glue within the context of is protein based. Gelatine Gelatin Gelatin (or gelatine) is a translucent, colorless, brittle (when dry), flavorless solid substance, derived from the collagen inside animals' skin and bones. It is commonly used as a gelling agent in food, pharmaceuticals, photography, and cosmetic manufacturing. Gelatin is an irreversibly hydrolysed form of collagen.
