What this shows Costar's Innovation Score is 27.0/100 (22nd 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 Costar?

Each dot is one of Costar’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). Costar’s own 18.8 claims/patent is at or below the 20.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Costar's grants concentrate

CoStar Realty Information, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 80% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2021. By volume, Costar sits between ClearingBid, Inc. and ColdBore Technology Inc..

Costar's three-year grant acceleration

CoStar Realty Information, Inc. shows 1 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.
