What this shows Hemotek's Innovation Score is 30.1/100 (33rd 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 Hemotek?

Each dot is one of Hemotek’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). Hemotek’s own 16.7 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hemotek's grants concentrate

Hemotek, LLC is a focused PatentsView assignee: 8 CPC subclasses with 50% of grants classified under C10L (Fuels NOT Otherwise Provided FOR; Natural GAS; Synthetic Natural GAS Obtained BY Processes NOT Covered BY Subclasses C10g OR C10K; Liquified Petroleum GAS; USE OF Additives TO Fuels OR FIRES; Fire-lig). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2020. By volume, Hemotek sits between Heemskerk Vasteplanten BV and Herostone Quartz Surfaces Inc.

Hemotek's three-year grant acceleration

Hemotek, LLC shows 2 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.
