What this shows Rinnai's Innovation Score is 53.0/100 (top 9% 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 Rinnai?

Each dot is one of Rinnai’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). Rinnai’s own 13.5 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rinnai's grants concentrate

Rinnai America Corporation is a focused PatentsView assignee: 15 CPC subclasses with 76% of grants classified under F24H (Fluid Heaters, e.g. Water OR AIR Heaters, Having Heat-generating Means, e.g. Heat Pumps, IN General). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2016. By volume, Rinnai sits between Rehau AG + Co. and Röhm GmbH.

Rinnai's three-year grant acceleration

Rinnai America Corporation shows 17 grants in 2022–2024 against only 3 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.
