Practical Advice: WIPO Pay – WIPO’s online payment platform

The following question is answered: I have recently started using the ePCT system for filing my PCT applications.  I have noticed that the International Bureau has an online payment system called WIPO Pay.  Can this be used for all PCT applications and what are the different payment methods available? See here (pages 9 and 10).

Practical Advice: Automatic assignment of access rights when filing an international application via ePCT

The following question is answered: I recently used ePCT for the first time to prepare a zip file for filing a PCT application with the United States Patent and Trademark Office as receiving office (RO/US) in order to benefit form the many useful validations that are included in ePCT.  Although I downloaded the zip file from ePCT and successfully uploaded it to Patent Center of RO/US, after receiving Form PCT/IB/301 from the International Bureau to acknowledge receipt of the record copy, I realised that I do not have access rights to the application in ePCT.  It was my understanding that by uploading zip files created using ePCT I would automatically have access rights to the application in the ePCT system after the receiving office had transitted the record copy to the IB.  Why did this not happen in my case? See here (pages 8 to 10)
