You failed to understand "The Patent Cooperation Treaty". It isn't a International patent as I have explained many times. A PCT (Patent Cooperation Treaty) application does not mean the Patent has been granted, since there is no such thing as an "international patent", and the granting of the patent is up of each national or regional authority.
In other words, a PCT application, establishes a filing date only with the contracting states. But means the patent application must be filed and granted in each state/territory - that is why OWCP filed for Provisional patents in the US - they are placeholders for 1 year - but there hasn't been a formal patent application.
And certainly it doesn't say a international patent (which doesn't exist) supersedes a US patent.
