What this shows Rational's Innovation Score is 48.8/100 (top 16% 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 17.2 claims/patent is at or below the 17.6 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 International AG is a focused PatentsView assignee: 12 CPC subclasses with 80% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, Rational sits between Ramaxel Technology (SHENZHEN) Limited and Raycap Intellectual Property Ltd..

Rational's three-year grant acceleration

Rational International AG 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.
