What countries are covered by the PCT (Patent Cooperation Treaty)?

The Patent Cooperation Treaty is an international treaty providing for the filing of a international patent application which will allow an applicant to secure filing date in many countries at the same time.  The PCT system does not yield a global patent, per se, but allows for the streamlined international processing of the initial steps of the patent application to allow for handling in multiple countries at the same time.  Generally speaking, the deadline for the filing of the national phase conversion of the PCT application in individual countries is 30 months although this is not uniform across all countries – we are happy to provide more specific advice in this regard.  Some countries are also accessible through the PCT as members of regional patent conventions.  At the writing of this post, the following are the countries who are signatory to that treaty [there is a link at the bottom of this post to the most current update in this regard]:
