Plaintiff: E-Contact Techs
Defendants:
A case was filed against Apple et al. for infringement of patent number US5347579. The patent entitled ‘Personal Computer Diary’ was issued on Sep 13, 1994 and expired[i] on Sep 13, 2011. The current assignee[ii] of the patent is E-Contact Techs (source: MaxVal’s Assignment Database). The complaint stated that defendants’ mail products infringe claims covered in the ‘579 patent.
The case started with all the defendants but most of the defendants were dismissed from the case on plaintiff’s request. Microsoft was dismissed from this case and a separate case (1:12-cv-00040) was filed (which was closed in July 2012). The case then proceeded with Apple, Google and Toshiba as defendants. Judge, Leonard Davis signed off the judgment in which claims 10 and 12 were declared invalid and costs taxed against the plaintiff, thereby closing the case.
