What this shows Taiyo's Innovation Score is 36.9/100 (top 45% 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 Taiyo?

Each dot is one of Taiyo’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). Taiyo’s own 18.8 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Taiyo's grants concentrate

Taiyo INK MFG. Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 94.1% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2020. By volume, Taiyo sits between T.A.G. Medical Products Corporation Ltd. and TEL Nexx, Inc..

Taiyo's three-year grant acceleration

Taiyo INK MFG. Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
