What this shows MK's Innovation Score is 28.1/100 (26th percentile 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 MK?

Each dot is one of MK’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). MK’s own 10.7 claims/patent is ABOVE the 8.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where MK's grants concentrate

MK Electron Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 71.4% of grants classified under C22C (Alloys). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, MK sits between Mission Secure, Inc. and Modiquest B.V..

MK's three-year grant acceleration

MK Electron Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
