How can I figure out if PCT/AU2012/001589 is granted or not?

There is a prior art case with US 2,223,561 A patented in 1939, but I don't know how to track that case.

  • No need to "track" US 2,223,561, it's been expired for something like 60 years.

This is basically an Australian App -
PCT Reference: Application Number:PCT/AU2012/001589

The equivalent US App is US 2014-0370781 A1 The Public PAIR for the US App has the status as "Docketed New Case - Ready for Examination"

To track the application go to http://portal.uspto.gov/pair/PublicPair and type in the "Publication Number"

  • thank you - yes it is a PCT Application. BTW, what is a PCT Patent? Never heard of it. The countries' /regional Patent Office prosecute the PCT Application into a patent for their jurisdiction - where does PCT Patent happen?

  • The original application was filed in Australia, but it is a PCT application.

  • I should have said "application", not "patent". The process is described here, specifically the overview figure.

This PCT patent is currently in the National Phase, which means there are publications in multiple countries, each with its own status. You can find these on the "National Status" tab of the page you linked to:

Office                   Entry Date  National Number  National Status
Australia                03.07.2014  2012357650       Published: 24.07.2014
Canada                   02.06.2014  2857701          
European Patent Office   18.06.2014  2012859200       
United States of America 03.06.2014  14362446         Published: 18.12.2014

Each country has its own system for managing the publications. The USPTO provides US legal status via Public Pair. The Canadian and Australian patent systems have the status built into the web pages linked to from PatentScope and are easier to find. The EPO system is a little more complex, but the information is available on the Legal Status and Event History pages.

  • thanks again Vallismortis. What about the rest of the world? South America for example? It depends on the US system?

  • @CristobalCerda The last time I checked, there were over 80 patent authorities in different countries, and they have no dependency on the US system. Many of them are member states to the Patent Cooperation Treaty (PCT) but some are not. I can't account for them all, but the WIPO patent National Status is the definitive place to look for PCT patents.

  • The PCT now has 148 member states.

  • Not to be too picky, but I believe this is an application, not a patent.
