What this shows Tanaka's Innovation Score is 45.2/100 (top 24% 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 Tanaka?

Each dot is one of Tanaka’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). Tanaka’s own 10.1 claims/patent is ABOVE the 7.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tanaka's grants concentrate

Tanaka Denshi Kogyo K. K. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, Tanaka sits between T. W. Vending, Inc. and TAU Medical Inc..

Tanaka's three-year grant acceleration

Tanaka Denshi Kogyo K. K. 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.
