What this shows I.v.a.r.'s Innovation Score is 42.5/100 (top 30% 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 I.v.a.r.?

Each dot is one of I.v.a.r.’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). I.v.a.r.’s own 14.3 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where I.v.a.r.'s grants concentrate

I.V.A.R. S.P.A. is a focused PatentsView assignee: 11 CPC subclasses with 33.3% of grants classified under F24D (Domestic- OR Space-heating Systems, e.g. Central Heating SYSTEMS; Domestic Hot-water Supply SYSTEMS; Elements OR Components Therefor). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2015. By volume, I.v.a.r. sits between Hyogo College of Medicine and Iceye OY.

I.v.a.r.'s three-year grant acceleration

I.V.A.R. S.P.A. shows 4 grants in 2022–2024 against only 2 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.
