Armando graduated from Brown University in 1984 with a degree in International Relations and Economics. In 1987, he received his J.D. from the Columbia University Law School.

For over 20 years, Armando has focused on intellectual property, media and Internet matters and antitrust and trade regulation (including for Wal Mart, Shell and Unilever as well as smaller local companies.)

Armando won a precedent setting case in the First Circuit Court of Appeals for The Clorox Company in which the Appeals Court reversed the dismissal of a Lanham Act false advertising action brought by Clorox against Procter & Gamble. This decision, The Clorox Company Puerto Rico v. The Procter & Gamble Commercial Company, 228 F.3d 24 (1st Cir. Oct. 3, 2000), was the first false advertising case decided in the First Circuit.

He also won a landmark case in 1998, garnering a permanent injunction against a company illegally using the name of former Miss Universe Dayanara Torres in the first "right of publicity" action brought in Puerto Rico.

In 2001, Mr. Llorens successfully defended against a claim of trademark infringement for its client, PGD, Inc., in the case Doral Pharmamedics v. Pharmaceutical Generic Developers, Inc., 148 F. Supp. 2d 127 (D.P.R. 2001).

In 2002, Mr. Llorens represented Wal-Mart before the Federal Trade Commission and the Puerto Rico Justice Department in relation with its acquisition of the supermarket chain Amigo.

In 2004, Mr. Llorens argued before the First Circuit Court of Appeals regarding an antitrust matter of first impression in the circuit in the case Euromoda v. Zanella, Ltd. et al., 368 F.3d 11 (1st Cir. 2004.)
