The fee to be paid by a US PCT filer for a search carried out by IP Australia dropped today, from $1722 to $1631.
I mentioned this in a previous blog post.
You will not need to worry about accidentally paying an incorrect fee amount, because the e-filing systems have already been updated to reflect the new fee amount. For filers in RO/US, the EFS-Web system has already been updated. And for filers in RO/IB, the ePCT system has already been updated.
