What this shows Lanzhou's Innovation Score is 49.8/100 (top 14% 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 Lanzhou?

Each dot is one of Lanzhou’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). Lanzhou’s own 10.8 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lanzhou's grants concentrate

Lanzhou Institute OF Chemical Physics, Chinese Academy OF Sciences is a focused PatentsView assignee: 33 CPC subclasses with 30.4% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2019. By volume, Lanzhou sits between Kraco Enterprises, LLC. and Lonza Walkersville, Inc..

Lanzhou's three-year grant acceleration

Lanzhou Institute OF Chemical Physics, Chinese Academy OF Sciences shows 9 grants in 2022–2024 against only 5 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.
