What this shows JST's Innovation Score is 51.8/100 (top 11% 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 JST?

Each dot is one of JST’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). JST’s own 23.6 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where JST's grants concentrate

JST Power Equipment, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 95% of grants classified under H02B (Boards, Substations OR Switching Arrangements FOR THE Supply OR Distribution OF Electric Power). Peak complete grant year is 2024 (9 grants) versus a trough of 8 in 2023. By volume, JST sits between Jawaharlal Nehru Centre FOR Advanced Scientific Research and Just Fur Love LLC.

JST's three-year grant acceleration

JST Power Equipment, Inc. shows 17 grants in 2022–2024 against only 0 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.
