Someone on this thread was mentioning suing India for arbitral award. Let me tell a short story.
In the late 90s, an American company, RiceTek, filed and got patents for basmati rice. The Indian government opposed this patent and filed a case with WTO and the US patent office. Since basmati is a Pakistani product as well, the Indian government asked Pakistan to join the claim. The Pakistanis said that while they can provide paperwork and evidence to support the claim, they cannot share the cost of legal proceedings as it is too high.
So the Indian government fought the case and got the patents over-turned. Today, as a result, India and Pakistan have a joint claim over basmati as a local geographic indication, which cannot be patented by anyone else.
There is no punchline to this story. It is just a sad reality that Pakistan wouldn't think twice about giving up its claim over one of its top exports, as long as the claimant is not India. But when it comes to India, they are always aware of their rights.
