Late last month, Canada joined eleven other countries including the United States, Japan, and Australia in Hawaii for what many experts expected would be the final round of negotiations on the Trans Pacific Partnership. According to media reports, the Canadian government was among those expecting the talks on the proposed trade deal that covers nearly 40 per cent of world GDP to conclude, with officials lining up the corporate community to immediately express their support for the agreement. However, negotiators left Hawaii empty handed, as disputes over intellectual property laws, safeguards and tariffs for the dairy and sugar industries, as well as disagreement over the auto sector, could not be resolved. With Canada plunged into an election campaign hours later, the government sought to assure its TPP partners that it could continue to negotiate even while acting in a "caretaker" capacity. My weekly technology law column (Toronto Star version, homepage version) notes that while those negotiations are expected to resume in the weeks ahead, sources advise that Canada dropped numerous demands on key patent and copyright issues in Hawaii, likely in the mistaken belief that a concluded deal was imminent. Indeed, after withholding agreement on critical issues such as anti-patent trolling rules, website blocking, restrictions on digital locks, trademark classification, and border enforcement, Canadian negotiators caved to U.S. pressure but failed to garner agreement.
