What this shows HS's Innovation Score is 38.6/100 (top 40% 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 HS?

Each dot is one of HS’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). HS’s own 6.6 claims/patent is at or below the 8.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where HS's grants concentrate

HS R & A Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 37.5% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, HS sits between Hkc-us, LLC and Hycor Biomedical, LLC.

HS's three-year grant acceleration

HS R & A Co., Ltd. shows 7 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.
