When thousands of fast food restaurant outlets, coffee shops and hotels were hit with letters demanding $2,300 apiece for Wi-Fi licensing, Kirkland & Ellis came to the rescue. The letters were from Innovatio IP Ventures LLC, a nonpracticing entity targeting the end users of wireless network-access technology.

Moving to defend their customers, Cisco Systems Inc., Motorola Solutions Inc. and Netgear Inc. tapped Kirkland to spearhead the multidistrict litigation in U.S. District Court for the Northern District of Illinois, where Kirkland also represented defendants including McDon­alds Corp. and Starbucks Coffee Co.
