What this shows Digi's Innovation Score is 44.8/100 (top 25% 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 Digi?

Each dot is one of Digi’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). Digi’s own 18.0 claims/patent is ABOVE the 15.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Digi's grants concentrate

Digi International Inc. is a focused PatentsView assignee: 28 CPC subclasses with 47.2% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2015 (13 grants) versus a trough of 1 in 2020. By volume, Digi sits between Complete Genomics, Inc. and Foshan Shunde Midea Electrical Heating Appliances Manufacturing Co., Ltd..

Digi's three-year grant acceleration

Digi International Inc. shows 2 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.
