Cisco, filed in the Eastern District of Texas. Cisco is also named as a defendent in the lawsuit. In the original post, PTT alleged
that the filing date for ESN v. Cisco was changed from Oct. 15, 2007, to Oct. 16, 2007, after ESN's local counsel "called the EDTX court clerk, and convinced him/her to change the docket to reflect an October 16 filing date, rather than the October 15 filing date." The filing date is significant, Frenkel alleged in the blog, because the ESN patent that is the basis of the suit was not issued until Oct. 16.Interestingly, one of the plaintiff's lawyers is John Ward, Jr., who is the son of U.S. District Judge T. John Ward of the Eastern District."
