Does more volume mean deeper claims for Oldcastle?

Each dot is one of Oldcastle’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). Oldcastle’s own 19.6 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Oldcastle's grants concentrate

Oldcastle Infrastructure, Inc. is a focused PatentsView assignee: 18 CPC subclasses with 68.8% of grants classified under E03F (SEWERS; Cesspools). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2024. By volume, Oldcastle sits between OUR Pet's Company and Optoma Corporation.

Oldcastle's three-year grant acceleration

Oldcastle Infrastructure, Inc. shows 6 grants in 2022–2024 against only 9 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.
