TransTasman risks, page-11

ePCT national phase killed it.

The IP Offices decided to set aside the significant cost savings of a single trans tasman patent because it would quickly become redundant due ePCT national phase. Look at the 'most serious' reason from this article from IPH.

"Perhaps most seriously, the Committee learnt that World Intellectual Property Organisation (WIPO) is in the process of developing its ePCT system further to provide very similar benefits to the proposed SAP for national phase entry of International (PCT) patent applications. A pilot program for this proposed change to the ePCT system is already being developed between WIPO and various IP offices around the world, including IPONZ and IP Australia. This new system would likely quickly render the proposed SAP redundant for the vast majority of applications being filed in both countries."

As this representative of IPH made clear, ePCT will impact on the vast majority of applications filed in AU and NZ.
