What this shows Wuhan's Innovation Score is 29.3/100 (30th percentile 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 Wuhan?
Each dot is one of Wuhan’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). Wuhan’s own 14.3 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Wuhan's grants concentrate
Wuhan LL Science AND Technology Development Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2017. By volume, Wuhan sits between Wireless Instrumentation Systems AS and Water Tech, LLC.
Wuhan's three-year grant acceleration
Wuhan LL Science AND Technology Development Co., Ltd. shows 2 grants in 2022–2024 against only 7 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.
