What this shows Rational'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 Rational?

Each dot is one of Rational’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). Rational’s own 12.8 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rational's grants concentrate

Rational Aktiengesellschaft is a focused PatentsView assignee: 20 CPC subclasses with 66.7% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Rational sits between Qingdao Agricultural University and Reshape Lifesciences Inc..

Rational's three-year grant acceleration

Rational Aktiengesellschaft shows 7 grants in 2022–2024 against only 4 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.
