Does more volume mean deeper claims for Heritage?

Each dot is one of Heritage’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). Heritage’s own 15.1 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Heritage's grants concentrate

Heritage Research Group, LLC is a focused PatentsView assignee: 21 CPC subclasses with 61.9% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2022. By volume, Heritage sits between Hangzhou United Tools Co., Ltd. and Honeywell Safety Products USA, Inc..

Heritage's three-year grant acceleration

Heritage Research Group, LLC shows 2 grants in 2022–2024 against only 11 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.
