The second patent covers TyraTech's Extend™ technology, which harnesses the synergy between natural and synthetic compounds to achieve increased efficacy while reducing the environmental footprint of synthetic pesticides. This patent supports a number of the Company's animal health pipeline products, as well as pipeline products from Envance Technologies. The patent has a 20-year term, which expires in 2029.

The issuance of these patents raises TyraTech's patent portfolio to 21 granted United States and international patents protecting its proprietary screening platform and compositions. The Company currently has 50 United States and international patent applications pending. 

Bruno Jactel, Chief Executive Officer, said: "These new patents are a testimony to the quality and innovation behind TyraTech's technology and products. More importantly they will provide protection for TyraTech's products that are already in the market and for products that TyraTech is currently developing. Our research and development teams are continually working to develop new products and formulations that are patentable with the objective of strengthening our growth platform."
