Where OIL's grants concentrate

OIL Chem Technologies is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, OIL sits between Officine Metallurgiche G. Cornaglia S.P.A. and OM Digital Solutions Corporation.

OIL's three-year grant acceleration

OIL Chem Technologies shows 1 grants in 2022–2024 against only 3 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
