Where S's grants concentrate

S H Kelkar & Company Limited is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under C11B (Producing, e.g. BY Pressing RAW Materials OR BY Extraction From Waste Materials, Refining OR Preserving Fats, Fatty Substances, e.g. Lanolin, Fatty Oils OR WAXES; Essential OILS; Perfumes). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2018. By volume, S sits between Ryzera Corp. and S2B, Inc..

S's three-year grant acceleration

S H Kelkar & Company Limited shows 3 grants in 2022–2024 against only 1 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.
