EXHIBIT B UNITED STATES DISTRICT COURT EASTERN DISTRICT OF TEXAS MARSHALL DIVISION PA ADVISORS, LLC, Plaintiff, v. GOOGLE, INC., et al. Defendants. CASE NO. 2:07-cv-480-DF JURY TRIAL DEMANDED EXPERT REPORT OF ALAN H. GORDON profiles... . The Dasan and Siefert patents disclose the use of user profiles.
