You have no clue what you are talking about. BTW, good job with selectively misquoting Wikipedia. That article goes on to read, ""It should be noted, however, that unlike China, successive administrations (through RBI, the central bank) have not followed a policy of pegging the INR to a specific foreign currency at a particular exchange rate. RBI intervention in currency markets is solely to deliver low volatility in the exchange rates, and not to take a view on the rate or direction of the Indian rupee in relation to other currencies."
The rupee was never fixed against the dollar - it fluctuates continuously. The RBI (India's Central Bank, like the US Federal Reserve) intervenes periodically, buying or selling dollars IN THE MARKET, AT MARKET RATE to reduce volatility. This is called a managed float. Developing countries do this to reduce sudden runs on their currency.
However, the general trend has been that the Rupee has been steadily declining. One factor has been the huge public debt that the Indian government has built up.
And India never "violated" any patents. Indian law provided for "process" patents, instead of "product" patents, in pharmaceuticals. This meant that the same molecule could be created by a different process by another company without violating patent law. This is a far more sensible approach - the company creating the molecule has a head start of a year or two while others create alternative processes.
Seriously, stop generalising and read up some of the stuff you're pontificating about.
