What this shows 4tech's Innovation Score is 34.5/100 (48th percentile 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 4tech?

Each dot is one of 4tech’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). 4tech’s own 26.1 claims/patent is ABOVE the 15.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 4tech's grants concentrate

4Tech Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2017. By volume, 4tech sits between ZeniMax Media Inc. and ABC Technologies Inc..

4tech's three-year grant acceleration

4Tech Inc. shows 5 grants in 2022–2024 against only 12 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.
