In 1989 when South Africa changed their patent exhaustion law, big pharma filed a lawsuit against their new regulations. But by 2001 it had turned into a public relations disaster for pharma and they dropped the suit.
And what is more troubling, the US patent and US trade agencies have traditionally sided with pharma.
This is going to be a real war. And it seems the only way we’re going to win is a full court press in the court of public opinion.
