ITC investigation based on MRI's complaint against Coates Signco concerning electronic display devices, asserting the '740 patent and related patents. The ITC found no violation and issued no exclusion or cease-and-desist order.
Samsung petitioned for inter partes review of the '740 patent. The PTAB issued a final written decision holding all challenged claims unpatentable as obvious, and the Federal Circuit later affirmed.
MRI appealed the PTAB's final written decision in IPR2023-00254 invalidating the '740 patent; the appeal was consolidated with 24-2231, an appeal of IPR2023-00221 concerning the related '142 patent. The Federal Circuit affirmed, upholding the PTAB's construction of 'heat exchanger' and the obviousness invalidation of the '740 patent's challenged claims.
