(Toronto) BlackBerry said Tuesday it has launched a review of strategic options for its business portfolio.

The company clarified that the possibilities include spinning off one or more of its businesses, but are not limited to them.

BlackBerry Executive Chairman and CEO John Chen said the review was designed to identify and assess opportunities to improve shareholder value.

The board did not set a timeline for the completion of the review and clarified that there was no assurance the process would result in a transaction.

BlackBerry signed a deal in March with Malikie Innovations, a newly formed subsidiary of Key Patent Innovations, to sell a portfolio of what it says are non-essential patents, in a deal whose value could reach a maximum of 900 million.

The portfolio sold includes approximately 32,000 patents and applications related primarily to mobile devices, messaging and wireless networks.
