(NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, is pleased to announce that it has received 2 new international patents. This now brings Lexaria's total worldwide patent portfolio to 50.

"We are pleased to announce the addition of these patents as we continue to execute on our strategy to broaden Lexaria's patent portfolio.

Lexaria has been granted a new patent in Australia within its patent family #24, Compositions and Methods for Treating Epilepsy.

This new patent will expire in 2044.

Lexaria has also been granted a new patent in Japan within its patent family #20, Compositions and Methods for Sublingual Delivery of Nicotine. This patent joins already-existing patents within the same family in both the USA and Canada. This new patent will expire in 2043.
