This Madrid agreement or system has been around a long time, since the 1800s, and it's somewhat confusing. I read that there was a perceived flaw. This is the reason the United States, Canada, and Japan haven't been signatories to this. Has there been any work done to if the home registration was based under a central attack, something along those lines? Have they addressed those issues, or has Canada felt at this time that these were not sufficient things to worry about?
