What this shows Hotalux's Innovation Score is 42.0/100 (top 32% 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 Hotalux?

Each dot is one of Hotalux’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). Hotalux’s own 9.8 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hotalux's grants concentrate

HotaluX, Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 63.6% of grants classified under B64F (Ground OR Aircraft-carrier-deck Installations Specially Adapted FOR USE IN Connection With AIRCRAFT; Designing, Manufacturing, Assembling, Cleaning, Maintaining OR Repairing Aircraft, NOT Otherwise PR). Peak complete grant year is 2021 (9 grants) versus a trough of 2 in 2019. By volume, Hotalux sits between Hoshino Gakki Co., Ltd. and IQ-Analog Corporation.

Hotalux's three-year grant acceleration

HotaluX, Ltd. shows 16 grants in 2022–2024 against only 17 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.
