NanoViricides Inc. (NNVC)

[WorstLuck]

What would the basis be for a period of market exclusivity?

FDA website provides some answers.

http://www.fda.gov/Drugs/DevelopmentApprovalProcess/ucm079031.htm#How%20long%20is%20exclusivity%20granted%20for?

There should be more detailed information there or in other places that can be found by search for those inclined to search.

While I have no idea what NNVC is worth, I find it surprising that it still trades over $1.00!
