Abstract From the Canadian patent

Substances that bind to alloimmune-immunogen-absorbed (AIA) sera have been found to be effective in the prevention and therapy of autoimmune disease. It is conjectured that the mechanism involves indirect stimulation of suppressor T cells resulting in stabilization of the immune system. The administration of such substances is expected to be useful in the prevention and treatment of diseases that involve a failure of the immune system to distinguish adequately between self and nonself, including autoimmune diseases and immunodeficiency diseases.

Why it's free to use

  • Filed July 11, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 11, 2011.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 11, 2013.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
