Here are the ASX rules regarding continuous disclosure. Sure there are some escape clauses there but I fail to see how they matter, now it has been out on the newswires around the world. UQ have stated publicly that patents would remain with the drug owner/donor. 
[Continuous Disclosure: an Abridged Guide1.

These rules provide:
3.1 Once an entity is or becomes aware of any information concerning it that a reasonable person wouldexpect to have a material effect on the price or value of the entity’s securities, the entity must immediatelytell ASX that information.
3.1A Listing rule 3.1 does not apply to particular information while each of the following requirements is satisfiedin relation to the information:3.1A.1 One or more of the following 5 situations applies:
 It would be a breach of a law to disclose the information;
