Where CSR's grants concentrate

CSR Building Products Limited is a focused PatentsView assignee: 15 CPC subclasses with 54.5% of grants classified under E04B (GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2019. By volume, CSR sits between CRM ICBG (wuxi) Co., Ltd. and CTF Solar Gmbh.

CSR's three-year grant acceleration

CSR Building Products Limited shows 3 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.
