Does more volume mean deeper claims for Sinopec?

Each dot is one of Sinopec’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Sinopec’s own 16.2 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sinopec's grants concentrate

Sinopec Petroleum Engineering Technology Research Institute Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). By volume, Sinopec sits between Singapore Technologies Dynamics PTE Ltd and Sipra Patententwicklungs- und Beteiligungsgesellschaft mbH.

Sinopec's three-year grant acceleration

Sinopec Petroleum Engineering Technology Research Institute Co., Ltd. shows 6 grants in 2022–2024 against only 0 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.
