What this shows Hanmi's Innovation Score is 35.2/100 (top 50% 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 Hanmi?

Each dot is one of Hanmi’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). Hanmi’s own 18.3 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hanmi's grants concentrate

Hanmi Science Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 82.2% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2020. By volume, Hanmi sits between Geron Corporation and Ii-vi Incorporated.

Hanmi's three-year grant acceleration

Hanmi Science Co., Ltd shows 2 grants in 2022–2024 against only 8 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.
