Acacia Research has announced a settlement in its patent infringement suit against AstraZeneca. The suit, Accuhale vs. AstraZeneca, was filed in December 2011, shortly after Acacia announced that it had acquired patents for inhaler technology from “a major medical company.” No terms were disclosed.
The suit claimed that AstraZeneca’s Symbicort pMDI infringed on US Patent No. 5,718,355, “Indicator Device Responsive to Axial Force for use with Inhaler.”
