What this shows Sifive's Innovation Score is 51.4/100 (top 11% 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 Sifive?

Each dot is one of Sifive’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). Sifive’s own 19.9 claims/patent is ABOVE the 18.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sifive's grants concentrate

SiFive, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 92.3% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2021 (12 grants) versus a trough of 2 in 2020. By volume, Sifive sits between Peltbeam Inc. and TrueCar, Inc..

Sifive's three-year grant acceleration

SiFive, Inc. shows 29 grants in 2022–2024 against only 14 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.
