What this shows Sinopec's Innovation Score is 47.9/100 (top 18% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

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 16.9 claims/patent is ABOVE the 9.6 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 Engineering Incorporation is a focused PatentsView assignee: 9 CPC subclasses with 71.4% of grants classified under C10G (Cracking Hydrocarbon OILS; Production OF Liquid Hydrocarbon Mixtures, e.g. BY Destructive Hydrogenation, Oligomerisation, Polymerisation ; Recovery OF Hydrocarbon Oils From Oil-shale, Oil-sand, OR GAS). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2015. By volume, Sinopec sits between Simpson Biotech Co., Ltd. and SIW Engineering PTE. Ltd..

Sinopec's three-year grant acceleration

Sinopec Engineering Incorporation shows 3 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.
