What this shows Kitz's Innovation Score is 56.0/100 (top 6% 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 Kitz?

Each dot is one of Kitz’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). Kitz’s own 8.3 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kitz's grants concentrate

Kitz Corporation is a focused PatentsView assignee: 27 CPC subclasses with 60.5% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2016. By volume, Kitz sits between Juluen Enterprise Co., Ltd. and Lentigen Technology, Inc..

Kitz's three-year grant acceleration

Kitz Corporation shows 19 grants in 2022–2024 against only 6 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.
