What this shows NDK's Innovation Score is 40.7/100 (top 35% 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 NDK?

Each dot is one of NDK’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). NDK’s own 11.5 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where NDK's grants concentrate

NDK SAW Devices Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, NDK sits between Ncardia B.V. and NEM Energy B.V..

NDK's three-year grant acceleration

NDK SAW Devices Co., Ltd. shows 5 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.
