What this shows Nanjing's Innovation Score is 40.5/100 (top 35% 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 Nanjing?

Each dot is one of Nanjing’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). Nanjing’s own 9.4 claims/patent is ABOVE the 5.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanjing's grants concentrate

Nanjing Gekof Institute OF Environmental Protection Technology & Equipment Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Nanjing sits between Namesforlife, LLC and Nanjing University OF Finance AND Economics.

Nanjing's three-year grant acceleration

Nanjing Gekof Institute OF Environmental Protection Technology & Equipment 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.
