What this shows Groundhog's Innovation Score is 45.1/100 (top 24% 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 Groundhog?

Each dot is one of Groundhog’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). Groundhog’s own 13.0 claims/patent is ABOVE the 5.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Groundhog's grants concentrate

Groundhog Inc. is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Groundhog sits between Gregg Drilling, LLC and Guangdong Jetfast Portable Lighting Co., Ltd..

Groundhog's three-year grant acceleration

Groundhog Inc. shows 5 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.
