C10M LUBRICATING COMPOSITIONS (well drilling compositions C09K8/02); USE OF CHEMICAL SUBSTANCES EITHER ALONE OR AS LUBRICATING INGREDIENTS IN A LUBRICATING COMPOSITION (mould release, i.e. separating, agents for metals B22C3/00, for plastics or substances in a plastic state, in general B29C33/56, for glass C03B40/02; textile lubricating compositions D06M11/00, D06M13/00, D06M15/00; immersion oils for microscopy G02B21/33)
Description
C10M covers lubricating compositions and individual chemical substances used as lubricants or lubricating additives. This includes formulated oils, greases, and other lubricant products, as well as specific chemical compounds (such as base oils, viscosity modifiers, anti-wear agents, detergents, and corrosion inhibitors) employed in lubricating applications. The subclass addresses both the composition of finished lubricating products and the functional role of chemical ingredients within those compositions.
Filing statistics
CPC subclass C10M recorded 41,664 patent applications worldwide between 2013 and 2023. Annual filings declined from 3,023 in 2013 to 2,626 in 2023 (-13%), peaking at 5,458 applications in 2016. The most active applicants in class C10 are SINOPEC (CHINA PETROCHEMICAL CORPORATION) (5,831 applications), SAUDI ARABIAN OIL COMPANY (2,918 applications) and IFPEN (IFP ENERGIES NOUVELLES) (2,305 applications).
