What this shows Jdrf's Innovation Score is 39.3/100 (top 39% 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 Jdrf?

Each dot is one of Jdrf’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). Jdrf’s own 14.8 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jdrf's grants concentrate

Jdrf Electromag Engineering Inc. is a focused PatentsView assignee: 14 CPC subclasses with 83.3% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, Jdrf sits between Jack Kennedy Metal Products & Buildings, Inc. and Jiangsu Tasly Diyi Pharmaceuticals Co., Ltd..

Jdrf's three-year grant acceleration

Jdrf Electromag Engineering Inc. shows 5 grants in 2022–2024 against only 4 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.
