said by Link Logger: ...How else would you build such a process to protect copyrights?
Like anything else involving cross-national participants, you would impound the disputed material; file notification with a court, which would then attempt to determine ownership and notify those owners in writing; after a defined period of time, the court would determine whether a timely response had occurred from the owners (or their legal representatives). If the owners responded, there would be a hearing or civil trial on the charges/complaints; if the owners failed to respond, the court could issue a finding and assess penalty, including destruction of the material. If the problem was recurrent over time from one supplier or importer, an injunction could be issued by the court to allow the authorities to automatically intervene and destroy the recurring material.
It's not that complicated... it's simply due process, and it's done all the time in other venues. Except where copyright is involved - for some reason, copyright has come to exist as a law unto itself, to be enforced unilaterally by the copyright holder/accuser.
