On February 27, 2017, BriaCell™ filed an international patent application under the Patent Cooperation Treaty (PCT) to further expand its intellectual property portfolio underlying the Company’s current and anticipated pipeline of whole-cell cancer immunotherapeutics including Bria-IMT™ and Bria-OTS™. The PCT application (PCT/US2017/019757) claims priority to two provisional patent applications filed by the Company with the USPTO in 2016. It, in essence, provides the framework for additional whole-cell cancer immunotherapeutics beyond Bria-IMT™ and strategies for patient-specific selection of the most likely effective whole-cell immunotherapeutic (BriaDx™). The PCT application entered the National Phase in the second half of 2018 and was granted in Japan on June 21, 2021.

BriaCell was recently awarded an Australian patent (Patent No. 2017224232, extends to February 27, 2037) covering composition of matter and method of use for its whole-cell cancer immunotherapy technology in Australia.).

BriaCell has also received an Issue Notification from the USPTO for the composition of matter and method of use of its personalized off-the-shelf cell-based immunotherapy for cancer. The patent was issued on January 24, 2023 as US Patent No. 11,559,574 B2 with the term extending to May 25, 2040.
