Does more volume mean deeper claims for D-tech?
Each dot is one of D-tech’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). D-tech’s own 26.0 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where D-tech's grants concentrate
D-tech UK Ltd is a focused PatentsView assignee: 1 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 (2 grants) versus a trough of 1 in 2017. By volume, D-tech sits between Cyxtera Data Centers, Inc. and Daewon Industry Company.
D-tech's three-year grant acceleration
D-tech UK Ltd shows 3 grants in 2022–2024 against only 1 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.
