Does more volume mean deeper claims for Harpoon?

Each dot is one of Harpoon’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). Harpoon’s own 18.3 claims/patent is ABOVE the 16.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Harpoon's grants concentrate

Harpoon Therapeutics, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under C07K (Peptides). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2017. By volume, Harpoon sits between Hoya Candeo Optronics Corporation and Hong Kong Ecoaqua Co., Limited.

Harpoon's three-year grant acceleration

Harpoon Therapeutics, Inc. shows 7 grants in 2022–2024 against only 10 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.
