Biological drugs patent expiration

Returning to biologies, it seems that the technology is so specialized that any intervention by generic drug manufacturers when the patent(s) expire is unlikely to significantly reduce the cost to the consumer, and it may well be much less than that anticipated by some journalists. 

However, in filing an application as soon as possible, a lot of problems can be generated. The term of a patent starts to rnn even before the prodnct is marketed. As a period of at least 7-10 years is required for the development of a new drug after a compound and its analogs have been prepared and biologically tested, the patent terms can expire before the prodnct begins to prodnce any real profits.
