What this shows Koska's Innovation Score is 43.9/100 (top 27% 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 Koska?

Each dot is one of Koska’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). Koska’s own 13.3 claims/patent is ABOVE the 7.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Koska's grants concentrate

Koska Family Limited is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2020. By volume, Koska sits between Kochi Prefectural Public University Corporation and Kultevat, Inc..

Koska's three-year grant acceleration

Koska Family Limited shows 6 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.
