What this shows Paloma's Innovation Score is 27.8/100 (25th percentile 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 Paloma?

Each dot is one of Paloma’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). Paloma’s own 3.6 claims/patent is at or below the 17.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Paloma's grants concentrate

Paloma Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 61.5% 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 2015 (3 grants) versus a trough of 1 in 2017. By volume, Paloma sits between Owlstone Inc. and Pathak Holdings LLC.

Paloma's three-year grant acceleration

Paloma Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
