Does more volume mean deeper claims for Yanegijutsukenkyujo?

Each dot is one of Yanegijutsukenkyujo’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). Yanegijutsukenkyujo’s own 3.3 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yanegijutsukenkyujo's grants concentrate

Yanegijutsukenkyujo Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under H02S (Generation OF Electric Power BY Conversion OF Infrared Radiation, Visible Light OR Ultraviolet Light, e.g. Using Photovoltaic [PV] Modules). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2016. By volume, Yanegijutsukenkyujo sits between X-Spine Systems, Inc. and Zhejiang Pride Leisure Products Co., Ltd..

Yanegijutsukenkyujo's three-year grant acceleration

Yanegijutsukenkyujo Co., Ltd. shows 1 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.
