(Telecompaper) Lenovo is actively considering a bid for all of BlackBerry, people familiar with the matter told the Wall Street Journal. Bids for BlackBerry are due by 04 November, according to the paper's sources. Last month, BlackBerry reached a preliminary USD 4.7 billion buyout deal with Fairfax Financial Holdings, one of its largest shareholders. Others that have been considering BlackBerry bids include Cerberus Capital Management, which has also signed a non-disclosure agreement to look at the company's books, and BlackBerry co-founders Mike Lazaridis and Doug Fregin, who recently disclosed their interest in a public filing. China-based Lenovo is already bigger than BlackBerry in the smartphone market, accounting for 4.7 percent of global sales in Q2 versus 2.7 percent for BlackBerry, according to Gartner.
