Does more volume mean deeper claims for Deltatek?

Each dot is one of Deltatek’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). Deltatek’s own 19.7 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Deltatek's grants concentrate

Deltatek Oil Tools Limited is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, Deltatek sits between Delsun Co., Ltd. and Dentec Safety Specialists Inc..

Deltatek's three-year grant acceleration

Deltatek Oil Tools Limited shows 4 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.
