What this shows Infirst's Innovation Score is 37.2/100 (top 44% 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 Infirst?

Each dot is one of Infirst’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). Infirst’s own 20.7 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Infirst's grants concentrate

Infirst Healthcare Limited is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (11 grants) versus a trough of 1 in 2022. By volume, Infirst sits between IP Reservoir, LLC and Kyodo Yushi Co., Ltd..

Infirst's three-year grant acceleration

Infirst Healthcare Limited shows 7 grants in 2022–2024 against only 19 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.
