What this shows Sofec's Innovation Score is 49.3/100 (top 15% 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 Sofec?

Each dot is one of Sofec’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). Sofec’s own 20.9 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sofec's grants concentrate

Sofec, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 96.3% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2019. By volume, Sofec sits between Shanghai Hode Information Technology Co., Ltd. and Solmetex, LLC.

Sofec's three-year grant acceleration

Sofec, Inc. shows 10 grants in 2022–2024 against only 6 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.
