Does more volume mean deeper claims for Calin?

Each dot is one of Calin’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). Calin’s own 17.7 claims/patent is ABOVE the 17.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Calin's grants concentrate

Calin Technology Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2016. By volume, Calin sits between C.I.V.-CONSORZIO Italiano VIVAISTI-SOCIETÀ Consortile A R.L. and Caringo, Inc..

Calin's three-year grant acceleration

Calin Technology Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
