What this shows Mayekawa's Innovation Score is 49.8/100 (top 14% 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 Mayekawa?

Each dot is one of Mayekawa’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). Mayekawa’s own 10.1 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Mayekawa's grant cadence moved

Between 2020–2024, Mayekawa MFG. Co., Ltd. received 21 grants versus 30 in 2015–2019 (-30% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2017 at 9 grants and bottomed in 2023 at 1. Lead class A22C accounts for 43.9% of the portfolio across 50 subclasses. Volume neighbours: Lintec OF America, Inc. (#5,224) and Mobius Imaging, LLC (#5,232).

Mayekawa's three-year grant acceleration

Mayekawa MFG. Co., Ltd. shows 10 grants in 2022–2024 against only 16 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.
