Does more volume mean deeper claims for Seerstone?
Each dot is one of Seerstone’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). Seerstone’s own 16.9 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Seerstone's grants concentrate
Seerstone, LLC is a focused PatentsView assignee: 29 CPC subclasses with 88% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2017 (11 grants) versus a trough of 1 in 2016. By volume, Seerstone sits between Switch Materials, Inc. and Shin Nippon Biomedical Laboratories, Ltd..
Seerstone's three-year grant acceleration
Seerstone, 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.
