In what can be seen as a turning point for BlackBerry, the Canadian iconic company has filed a patent lawsuit against internet telephony firm Avaya. BlackBerry claims Avaya has infringed eight of its U.S. patents, and that BlackBerry should be paid for its history of innovation going back nearly 20 years. "BlackBerry revolutionized the mobile industry," the company's lawyers said. "BlackBerry... has invented a broad array of new technologies that cover everything from enhanced security and cryptographic techniques, to mobile device user interfaces, to communication servers, and many other areas." From an article on Iam Media: The move comes just over a year since Blackberry announced itself as a major player in the monetisation space with an agreement signed with Cisco, in which the Canadian company not only secured a cross-licensing deal but also "a license fee from Cisco." Another royalty-bearing deal was done with an unnamed company around the same time. Since then, the company has also signed two more deals with Canon and International Game Technology, both of which look to contain a royalties element to them; while in January it emerged that late last year Blackberry had sold a portfolio of patents to investment firm Centerbridge Partners for as much as $50 million. Blackberry CEO John Chen has made clear that he sees the company's patent assets as a key element in his plans. "We have today about 44,000 patents. The good thing about this is that we also have one of the youngest patent portfolios in the entire industry, so monetization of our patents is an important aspect of our turnaround," he told delegates at a summit in Waterloo, Ontario, last September. He was at it again in May during an earnings call with analysts when he stated: "Many people have wanted to buy the patents... But I'm not really in a patent-selling mode, I'm in a patent licensing mode."
