Lubricating compositions characterised by purely physical criteria

Official title: Lubricating compositions characterised by purely physical criteria, e.g. containing as base-material, thickener or additive, ingredients which are characterised exclusively by their numerically specified physical properties, i.e. containing ingredients which are physically well-defined but for which the chemical nature is either unspecified or only very vaguely indicated (chemically defined ingredients C10M101/00 - C10M169/00; petroleum fractions C10M101/02, C10M121/02, C10M159/04)

C10M171/00 (Lubricating compositions characterised by purely physical criteria) appears on 1,747 US grants and 1,686 published applications in this corpus.
