What this shows Day's Innovation Score is 37.9/100 (top 42% 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 Day?

Each dot is one of Day’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). Day’s own 16.7 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Day's grants concentrate

Day International, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 77.8% of grants classified under B41F (Printing Machines OR Presses). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2023. By volume, Day sits between DataTorrent, Inc. and Deepgram, Inc..

Day's three-year grant acceleration

Day International, Inc. shows 1 grants in 2022–2024 against only 0 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.
