What this shows Hifi's Innovation Score is 47.6/100 (top 18% 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 Hifi?

Each dot is one of Hifi’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). Hifi’s own 19.5 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hifi's grants concentrate

Hifi Engineering Inc. is a focused PatentsView assignee: 20 CPC subclasses with 46.5% of grants classified under G01H (Measurement OF Mechanical Vibrations OR Ultrasonic, Sonic OR Infrasonic Waves). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2015. By volume, Hifi sits between GeeLux Holdings, Ltd. and Horizon International Inc..

Hifi's three-year grant acceleration

Hifi Engineering Inc. shows 19 grants in 2022–2024 against only 18 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.
