Where Sinopec's grants concentrate

Sinopec Research Institute OF Petroleum Engineering is a focused PatentsView assignee: 6 CPC subclasses with 44.4% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Sinopec sits between Silvus Technologies, Inc. and Sisvel International SA.

Sinopec's three-year grant acceleration

Sinopec Research Institute OF Petroleum Engineering shows 2 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.
