RIM faced several intellectual property challenges including patent infringement lawsuits from NTP, Motorola, Nokia, and Hunter Point Ventures regarding technologies related to wireless email, mobile devices, and music playlists. RIM settled the NTP lawsuit in 2006 for $612.5 million. These lawsuits and increased competition from Apple and Android hurt RIM's business revenue. However, RIM's Blackberry was once highly innovative as the premier smartphone providing secure email access and integration with corporate systems. RIM must continue innovating new blockbuster products and leverage its intellectual property portfolio to regain market share.
