Does more volume mean deeper claims for Calterah?

Each dot is one of Calterah’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). Calterah’s own 18.0 claims/patent is ABOVE the 14.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Calterah's grants concentrate

Calterah Semiconductor Technology (SHANGHAI) Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 57.1% of grants classified under H01Q (Antennas, i.e. Radio Aerials). By volume, Calterah sits between Cadequip, Inc. and Capitainer AB.

Calterah's three-year grant acceleration

Calterah Semiconductor Technology (SHANGHAI) Co., Ltd. shows 1 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.
