Re: Expiration dates of Rituxan patents

According to DNA itself, the US patents that protect Rituxan are 5,677,180 (“Chimeric antibody with specificity to human B cell surface antigen”) and 5,736,137 (“Therapeutic application of chimeric and radiolabeled antibodies to human B lymphocyte restricted differentiation antigen for treatment of B cell lymphoma”).

The ‘180’ patent expires in Oct 2014 and the ‘1378’ patent expires in Apr 2015.

GTC believes that only the ‘180’ patent is relevant to GTC’s CD20 mAb program.
