Genetic Technologies Executes

Settlement and License Agreement with PreventionGenetics, LLC

In compliance with ASX Continuous Disclosure Rules, Genetic Technologies Limited (ASX: GTG; NASDAQ: GENE) is pleased to report it has now executed a Settlement and License Agreement with PreventionGenetics, LLC of Marshfield, Wisconsin, USA.

In late 2012, GTG reported that it had filed suit against PreventionGenetics LLC in the Western District of Wisconsin under its Assertion program in USA. Given the Parties have now reached a final settlement, such legal action against PreventionGenetics, LLC will now be dismissed.

The precise commercial terms of the Agreement with PreventionGenetics, LLC are covered by formal confidentiality provisions and cannot be disclosed.  This settlement was achieved as a result of GTG’s continuing patent monetization efforts in the US and other jurisdictions.
