What this shows Rubycon's Innovation Score is 44.6/100 (top 25% 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 Rubycon?

Each dot is one of Rubycon’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). Rubycon’s own 11.0 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rubycon's grants concentrate

Rubycon Corporation is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H01G (CAPACITORS; Capacitors, Rectifiers, Detectors, Switching Devices, Light-sensitive OR Temperature-sensitive Devices OF THE Electrolytic Type). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Rubycon sits between RSI Home Products Management, Inc. and Radius Health, Inc..

Rubycon's three-year grant acceleration

Rubycon Corporation shows 4 grants in 2022–2024 against only 1 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.
