What this shows Rexair's Innovation Score is 45.5/100 (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 Rexair?

Each dot is one of Rexair’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). Rexair’s own 11.6 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rexair's grants concentrate

Rexair LLC is a focused PatentsView assignee: 9 CPC subclasses with 55.6% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2018. By volume, Rexair sits between Research Center FOR Eco-environmental Scinces, Chinese Academy OF Sciences and Roal OY.

Rexair's three-year grant acceleration

Rexair LLC shows 8 grants in 2022–2024 against only 0 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.
