The human antibodies can be produced in a non-human transgenic animal, e.g. a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are derivatives of the human antibodies (e.g. bispecific antibodies and immunoconjugates) pharmaceutical compositions , comprising the human antibodies non-human transgenic animals and hybridomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.

Why it's free to use

  • Filed January 7, 2003 and granted March 19, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 7, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 7, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
