In spite of talk that Samsung and Blackberry were discussing an acquisition, both companies have denied the rumor.

The Reuters news service reported on Wednesday that Samsung had offered to buy BlackBerry for between $13.35 and $15.49 per share.

A Samsung spokeswoman said on Thursday: "Media reports of the acquisition are groundless."

The company said in a statement: “BlackBerry has not engaged in discussions with Samsung with respect to any possible offer to purchase BlackBerry.”

Though BlackBerry is far from the mobile player it once was, it still has respected security technology, patents, automotive and industrial software from its QNX division, and a loyal following among users in enterprises and some developing markets.
