Where SPM's grants concentrate

SPM Oil & Gas Inc. is a focused PatentsView assignee: 33 CPC subclasses with 62.5% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2023 (20 grants) versus a trough of 4 in 2021. By volume, SPM sits between Shenzhen BYD Auto R&D Company Limited and Syniverse Technologies, LLC.

SPM's three-year grant acceleration

SPM Oil & Gas Inc. shows 55 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.
