What this shows Yuhan's Innovation Score is 44.1/100 (top 26% 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 Yuhan?
Each dot is one of Yuhan’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). Yuhan’s own 15.9 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Yuhan's grants concentrate
Yuhan Corporation is a focused PatentsView assignee: 10 CPC subclasses with 74.1% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (11 grants) versus a trough of 1 in 2018. By volume, Yuhan sits between Thor Tech, Inc. and 128 Technology, Inc..
Yuhan's three-year grant acceleration
Yuhan Corporation shows 23 grants in 2022–2024 against only 16 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.
