The USPTO instituted inter partes review (IPR) of two Arendi SARL patents (7,496,854, 7,917,843). The IPR proceedings were initiated by Apple, Google, and Motorola Mobility, who along with HTC, LG, Microsoft, Nokia, RIM (Blackberry), Samsung, Sony, and Yahoo, have been sued by Arendi for alleged patent infringement. The two patents originated with Arendi and relate to retrieval of data corresponding to content typed into a field. Apple, Google, and Motorola Mobility jointly filed three petitions in December 2013 requesting that the Patent Trial and Appeal Board (PTAB) review all the claims of the ‘854 and ‘843 patents.
