Lund, Sweden – 2 July, 2013 – BioInvent International AB (OMXS: BINV) today
announces that it has signed an extension to its 2009 license agreement with
Mitsubishi Tanabe Pharma Corporation for the development of antibodies from
BioInvent's n-CoDeR® library. Under the terms of the extension, Mitsubishi
