Does more volume mean deeper claims for Cirel?
Each dot is one of Cirel’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). Cirel’s own 9.8 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Cirel's grants concentrate
Cirel Systems Private Limited is a focused PatentsView assignee: 7 CPC subclasses with 33.3% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Cirel sits between CHU Sainte-justine and Cleanr Inc..
Cirel's three-year grant acceleration
Cirel Systems Private Limited shows 2 grants in 2022–2024 against only 3 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.
