Where Independence's grants concentrate

Independence Oilfield Chemicals LLC is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2018. By volume, Independence sits between Imricor Medical Systems, Inc. and Infovista SAS.

Independence's three-year grant acceleration

Independence Oilfield Chemicals LLC shows 4 grants in 2022–2024 against only 4 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.
