INDEXING SCHEME ASSOCIATED WITH SUBCLASS C10M RELATING TO LUBRICATING COMPOSITIONS

Introduced: January 1985

Description

C10N is an indexing and classification scheme used to organize and cross-reference patents within the petroleum, gas, coke, and lubricants sector (subclass C10). It provides a structured framework for categorizing inventions related to fossil fuel extraction, processing, refining, fuel production, and lubricant formulation. This indexing scheme facilitates systematic retrieval and navigation of technical disclosures across the broad C10 technology domain by establishing logical groupings and terminology standards. Patent examiners and researchers use C10N to locate relevant prior art and identify the specific technical aspects of fuel and lubricant-related innovations.
