What this shows YKK's Innovation Score is 37.0/100 (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 YKK?

Each dot is one of YKK’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). YKK’s own 20.4 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where YKK's grants concentrate

YKK Corporation of America is a focused PatentsView assignee: 17 CPC subclasses with 54.5% of grants classified under A44B (Buttons, Pins, Buckles, Slide Fasteners, OR THE Like). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, YKK sits between Xiamen Roadzup Outdoor Products Co., Ltd. and York Guangzhou Air Conditioning and Refrigeration Co., Ltd..

YKK's three-year grant acceleration

YKK Corporation of America shows 1 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.
