Celltrion and Teva commence proceedings for trastuzumab patents

Jan 19, 2018

Celltrion and Teva commence proceedings in District Court (Northern District of California) seeking DJ that 38 patents relating to trastuzumab are invalid, unenforceable and/or not-infringed.  This follows Celltrion/Teva’s US ABLA filing for biosimilar trastuzumab in late July 2017, and subsequent patent dance, and will test the boundaries of the availability of “DJ-within ABLA”.
