Does more volume mean deeper claims for Delta?

Each dot is one of Delta’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). Delta’s own 16.1 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Delta's grants concentrate

Delta PDS Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 64.7% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2022 (5 grants) versus a trough of 2 in 2020. By volume, Delta sits between Dari-tech, Inc. and Dlvr, LLC.

Delta's three-year grant acceleration

Delta PDS Co., Ltd. shows 14 grants in 2022–2024 against only 2 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.
