TORONTO, ONTARIO--(Marketwired - Oct. 11, 2017) - Microbix Biosystems Inc. (TSX:MBX), an innovator of biological products and technologies, is pleased to announce the withdrawal of legal claims alleging patent infringement that were filed in Canadian Federal Court against Microbix by ZeptoMetrix Corporation in October, 2016.

The allegations by ZeptoMetrix have been withdrawn, following a settlement reached by the two companies. The withdrawal of the lawsuit is "with prejudice," meaning that these allegations cannot be reasserted in Federal Court by ZeptoMetrix in the future.

"This was an unfortunate matter that we are glad to put behind us," stated Cameron Groome, CEO and President of Microbix. "We respect other parties' intellectual property and are pleased to end this dispute. Customers can now freely decide between the value propositions of each company's products."

The lawsuit involved a patent with claims related to methods for the production of proficiency and quality assurance antigen controls that support diagnostic tests based on the nucleic acid makeup of pathogens. Such tests are commonly referred to as "molecular" or "DNA" diagnostics. Molecular diagnostics are the fastest growing segment of the testing industry, and supplying controls for molecular diagnostics controls is an important emerging market opportunity for Microbix.

Microbix has committed to the development of a molecular controls product line under the brand name REDx Controls™. Further information about REDx Controls™ is available from Microbix via e-mail to [email protected] or by telephone at 905-361-8910.
