What this shows Xi'an's Innovation Score is 36.7/100 (top 46% 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 Xi'an?

Each dot is one of Xi'an’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). Xi'an’s own 9.5 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xi'an's grants concentrate

Xi'an Modern Chemistry Research Institute is a focused PatentsView assignee: 7 CPC subclasses with 90% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2019. By volume, Xi'an sits between X-therma, Inc. and Xiamen Topunive Technology Co., Ltd..

Xi'an's three-year grant acceleration

Xi'an Modern Chemistry Research Institute shows 2 grants in 2022–2024 against only 1 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.
