China Rescinds Viagra Patent: China yesterday defended its decision to overturn Pfizer's patent for Viagra in a ruling seen as a setback to protection of intellectual property rights in the country. The US makers of the top selling erectile disfunction drug were in breach of China's intellectual property rights (IPR) law when they failed to accurately explain "technological" uses of Viagra's key ingredient, an official with the State Intellectual Property Office (SIPO) said.

What a joke - this is my favorite quote - when talking to an official at SIPO, the official said:

"We did grant the patent to Pfizer before, but that does not mean that we are really giving it to you"

Great.
