Georgetown Rail Equipment Company v. Tetra Tech Canada, Inc.

Finnegan successfully defended Tetra Tech Canada Inc. (“Tetra Tech”) in a district court action brought by Georgetown Rail Equipment Company (“GREX”), asserting three patents against certain railroad track inspection systems allegedly sold by Tetra Tech. Finnegan filed several inter partes reviews (“IPRs”) against the asserted patents, and leveraged favorable institution decisions to stay the district court case. At the PTAB, Finnegan secured final written decisions in the IPRs, finding all challenged claims unpatentable, leading to the subsequent dismissal of the district court case.
