Re:	Mylan Pharmaceuticals Inc. v. FDA et al.,
	Civil Action No. 1:04cv00174 (N.D. W. Va.)

Dear Judge Keeley:

     On behalf of Mylan Pharmaceuticals Inc., the purpose of this letter is to notify the Court of, and explain to the Court the reason for, the attached notice of voluntary dismissal without prejudice that Mylan has today filed with the Clerk.

     During the proceedings at the preliminary injunction hearing, counsel for both FDA and P&G disclosed facts and positions that have a significant bearing on related aspects of the “authorized generic” question and the considerable anticompetitive effects of authorized generics on the industry. The importance of these issues to Mylan and the entire generic pharmaceutical industry has led Mylan to conclude that all potential claims and aspects of the problems raised by authorized generics should be presented for review together in one action. In these circumstances, and because of potential preclusion concerns, Mylan feels compelled to withdraw its action without prejudice at this time in order to evaluate all of the potential issues and claims concerning authorized generics arising out of the recent hearing.
