What this shows Sinopec's Innovation Score is 51.1/100 (top 12% 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 20.2 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 Dalian Research Institute OF Petroleum AND Petrochemicals Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 66.7% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). By volume, Sinopec sits between Sindoh Co., Ltd. and Sintratec AG.

Sinopec's three-year grant acceleration

Sinopec Dalian Research Institute OF Petroleum AND Petrochemicals Co., Ltd. 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.
