Does more volume mean deeper claims for Spirent?
Each dot is one of Spirent’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). Spirent’s own 20.1 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Spirent's grants concentrate
Spirent Communications PLC is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2016. By volume, Spirent sits between South 8 Technologies, Inc. and Stout Stuff, LLC.
Spirent's three-year grant acceleration
Spirent Communications PLC shows 10 grants in 2022–2024 against only 0 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.
