What this shows YSI's Innovation Score is 39.5/100 (top 38% 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 YSI?

Each dot is one of YSI’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). YSI’s own 17.5 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where YSI's grants concentrate

YSI, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 64.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, YSI sits between Xiamen Easo Co., Ltd. and Zerokey Inc..

YSI's three-year grant acceleration

YSI, Inc. shows 5 grants in 2022–2024 against only 6 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.
