BlackBerry's valuable patents: If anyone does buy BlackBerry, most of the value would be found in the company's patent portfolio. Chris Marlett, CEO of MDB Capital Group, an intellectual property-focused investment bank, values Blackberry's patents at $2 billion to $3 billion.
BlackBerry's patents, which Marlett called "the last big portfolio likely to go to sale anytime soon," would give any buyer a massive advantage in the competitive and highly litigious world of smartphones. The never-ending Apple v. Samsung lawsuits underscore the value of such a portfolio.

What's the rest of BlackBerry worth? Anil Doradla, a stock analyst at William Blair & Company, splits the rest of BlackBerry's business into two parts.
BlackBerry's "hardware, infrastructure and operating system" are worth another $2 billion, in Doradla's view. The third sector is BlackBerry's estimated 60 million subscribers, but that's tough to value "given that a buyer doesn't know if those subscribers will be around in a month."
In addition to those business sectors, BlackBerry had $2.6 billion in cash on hand at the end of last quarter.
