We recently assisted two clients in a counterfeit investigation in the People's Republic

counterfeit computer and telephone equipment. Twelve organized crime members
were arrested, several factories were closed, and an organization that employed 250
people in its criminal enterprise was put out of business. We developed market

purchases of equipment, and assisted in developing probable cause for search and
arrest warrants. Trademark Investigation
