Where Rexon's grants concentrate

Rexon Industrial Corp., Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 41.4% of grants classified under B23D (PLANING; SLOTTING; SHEARING; BROACHING; SAWING; FILING; SCRAPING; Like Operations FOR Working Metal BY Removing Material, NOT Otherwise Provided FOR). Peak complete grant year is 2019 (13 grants) versus a trough of 2 in 2022. By volume, Rexon sits between PTC Inc. and Real Value LLC.

Rexon's three-year grant acceleration

Rexon Industrial Corp., Ltd. shows 7 grants in 2022–2024 against only 18 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.
