Where Star's grants concentrate

Star Group IND. Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, Star sits between ST R&DTech LLC and Start Project, LLC.

Star's three-year grant acceleration

Star Group IND. Co., Ltd shows 4 grants in 2022–2024 against only 1 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.
