What this shows Hough's Innovation Score is 29.0/100 (29th percentile 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 Hough?

Each dot is one of Hough’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). Hough’s own 17.6 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hough's grants concentrate

Hough Ear Institute is a focused PatentsView assignee: 5 CPC subclasses with 83.3% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Hough sits between Hologram Holdings I, Inc. and HumanEyes Technologies Ltd..

Hough's three-year grant acceleration

Hough Ear Institute shows 1 grants in 2022–2024 against only 4 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.
