What this shows HTS's Innovation Score is 35.5/100 (top 49% 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 HTS?

Each dot is one of HTS’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). HTS’s own 23.4 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where HTS's grants concentrate

HTS LLC is a focused PatentsView assignee: 9 CPC subclasses with 81.8% of grants classified under F02B (Internal-combustion Piston ENGINES; Combustion Engines IN General). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2015. By volume, HTS sits between Hoteck Inc. and Hvac Inventors/Systemation, Inc..

HTS's three-year grant acceleration

HTS LLC shows 2 grants in 2022–2024 against only 6 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.
