Does more volume mean deeper claims for Hudson?

Each dot is one of Hudson’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). Hudson’s own 13.9 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hudson's grants concentrate

Hudson Products Corporation is a focused PatentsView assignee: 12 CPC subclasses with 66.7% of grants classified under F28F (Details OF Heat-exchange AND Heat-transfer Apparatus, OF General Application). Peak complete grant year is 2022 (5 grants) versus a trough of 2 in 2021. By volume, Hudson sits between Hothand, Inc and Human Matrix Sciences, LLC.

Hudson's three-year grant acceleration

Hudson Products Corporation shows 7 grants in 2022–2024 against only 2 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.
