Novartis: India rejects patent plea for cancer drug Glivec

India's Supreme Court has rejected a plea by Novartis to patent an updated version of its cancer drug, Glivec.
The Swiss drugmaker had been denied a patent by Indian authorities on the grounds that the new version was only slightly different from the old.
There were concerns that a patent could threaten access to cheap generic versions of drugs in poorer countries.
But some Western companies had warned that a decision against Novartis could discourage investment in research.
