Where Ihara's grants concentrate

Ihara Science Corporation is a focused PatentsView assignee: 7 CPC subclasses with 77.8% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, Ihara sits between IDM Global, Inc. and IMBA—INSTITUT FÜR Molekulare Biotechnologie GMBH.

Ihara's three-year grant acceleration

Ihara Science Corporation 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.
