What this shows Wostec's Innovation Score is 38.3/100 (top 41% 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 Wostec?

Each dot is one of Wostec’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). Wostec’s own 19.8 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wostec's grants concentrate

Wostec, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 90% of grants classified under B82Y (Specific Uses OR Applications OF NANOSTRUCTURES; Measurement OR Analysis OF NANOSTRUCTURES; Manufacture OR Treatment OF Nanostructures). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, Wostec sits between Witzenmann GmbH and Xenon Inc..

Wostec's three-year grant acceleration

Wostec, Inc. shows 2 grants in 2022–2024 against only 3 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.
