Does more volume mean deeper claims for Yamaichi?
Each dot is one of Yamaichi’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). Yamaichi’s own 7.7 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Yamaichi's grants concentrate
Yamaichi Electronics Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 62.5% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2022 (15 grants) versus a trough of 1 in 2019. By volume, Yamaichi sits between Vocollect, Inc. and Zillow, Inc..
Yamaichi's three-year grant acceleration
Yamaichi Electronics Co., Ltd. shows 28 grants in 2022–2024 against only 5 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.
