What this shows THE's Innovation Score is 45.4/100 (top 23% 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 THE?

Each dot is one of THE’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). THE’s own 8.7 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How THE's grant cadence moved

Between 2020–2024, THE Chugoku Electric Power Co., Inc. received 15 grants versus 26 in 2015–2019 (-42% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2017 at 9 grants and bottomed in 2023 at 2. Lead class Y02E accounts for 39% of the portfolio across 51 subclasses. Volume neighbours: Synapse Wireless, Inc. (#7,936) and TRW Automotive Electronics and Components GmbH (#7,944).

THE's three-year grant acceleration

THE Chugoku Electric Power Co., Inc. shows 5 grants in 2022–2024 against only 15 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.
