Research In Motion Corporation ("RIM") was the U.S.-incorporated affiliate of Canadian wireless-device maker Research In Motion Limited, the company best known for the BlackBerry smartphone. The parent was founded in 1984 (some accounts date incorporation to February 1985) in Waterloo, Ontario by Mike Lazaridis and Douglas Fregin, and was publicly traded on the TSX (RIM) and Nasdaq (RIMM). In January 2013 the parent announced it would rebrand, and in July 2013 it legally changed its name to BlackBerry Limited (NYSE: BB), under which it continues to trade today. Sources do not separately report headcount or revenue for the "Research In Motion Corporation" U.S. entity; at its peak the parent employed well over 10,000 people, and BlackBerry now reports revenue in the hundreds of millions of dollars after exiting handset manufacturing in 2016. I could not verify a distinct financial profile for the Corporation entity itself.
Products / operations. RIM designed, manufactured and marketed wireless communications devices and infrastructure: BlackBerry smartphones and the PlayBook tablet, the BlackBerry Enterprise Server / push-email service, its own radio modems, and later the QNX-based BlackBerry 10 platform (QNX acquired in 2010). This is an operating company, not a shell or assertion vehicle.
Litigation posture. Per the tracked data, Research In Motion Corporation appears once, as a defendant and never as a plaintiff — consistent with an operating company being targeted rather than asserting. The single case is a 2013 patent-infringement action filed in the plaintiff-friendly Eastern District of Texas, Marshall Division, before Judge Rodney Gilstrap.
Notable case. Rembrandt Wireless Technologies, LP v. Samsung Electronics Co., Ltd. et al. (E.D. Tex., No. 2:13-cv-00213, filed 2013-03-15) named RIM Corporation and RIM Ltd. alongside several Samsung entities. Plaintiff Rembrandt is a well-known non-practicing entity (an affiliate of Rembrandt IP Management) asserting U.S. Patent 8,023,580 on multi-modulation wireless communication against Bluetooth "EDR"-enabled devices, including the BlackBerry Z10, Q10, Bold, Torch and Curve lines. The case ran parallel to Rembrandt's Samsung action, in which a jury returned a $15.7M infringement verdict.
