What this shows Sharrow's Innovation Score is 45.6/100 (top 23% 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 Sharrow?

Each dot is one of Sharrow’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). Sharrow’s own 5.1 claims/patent is ABOVE the 4.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sharrow's grants concentrate

Sharrow Engineering LLC is a focused PatentsView assignee: 11 CPC subclasses with 27.3% of grants classified under B63H (Marine Propulsion OR Steering). Peak complete grant year is 2023 (8 grants) versus a trough of 1 in 2018. By volume, Sharrow sits between Scrub Daddy, Inc. and Shenzhen Qianyan Technology Ltd.

Sharrow's three-year grant acceleration

Sharrow Engineering LLC shows 16 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.
