Patent Office for patent number 8,480,631 entitled “Hazardous Agent Injection System.” The claims of this patent are directed toward an injection system for methotrexate and also a method for treating rheumatoid arthritis and other autoimmune diseases using an auto-injector or similar device for subcutaneous delivery of methotrexate.
