Where Tangtring's grants concentrate

Tangtring Seating Technology Inc. is a focused PatentsView assignee: 7 CPC subclasses with 63.6% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2018. By volume, Tangtring sits between Tuf-tite, Inc. and Tekcem.

Tangtring's three-year grant acceleration

Tangtring Seating Technology Inc. shows 5 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.
