http://en.wikipedia.org/wiki/Term_of_patent_in_the_United_States

For applications filed on or after June 8, 1995,[1] the patent term is 20 years from the filing date of the earliest U.S. application to which priority is claimed (excluding provisional applications).[2]

See: https://www.google.com/patents/US8182836?dq=elite+pharmaceuticals+laboratories+8,182,836&hl=en&sa=X&ei=I4MVVLSJO9PgsASEuIDADA&ved=0CB0Q6AEwAA

Filing date = 12/17/2009, priority date (estimated) 4/8/2003

now see:
http://en.wikipedia.org/wiki/Priority_right

In patent law, when a priority is validly claimed, the date of filing of the first application, called the priority date, is considered to be the effective date of filing

So it's 2003 plus 20 years = 2023.

However, the priority date in Google patents is estimated so perhaps Elite has determined through the USPTO that the priority date is in 2004.
