Does more volume mean deeper claims for Graybug?

Each dot is one of Graybug’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). Graybug’s own 42.1 claims/patent is ABOVE the 5.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Graybug's grants concentrate

Graybug Vision, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Graybug sits between Global Supercomputing Corporation and Gslide Corporation.

Graybug's three-year grant acceleration

Graybug Vision, Inc. shows 4 grants in 2022–2024 against only 3 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.
