Nokia attempts to block BlackBerry sales after patent dispute

It's not just Apple and Samsung...

Nokia has won a patent dispute with RIM over the inclusion of WLAN technology in its BlackBerry handsets, and has asked for a sales ban in the UK, US and Canada

The Finnish company made the disclosure by submitting a US court filing that asked for enforcement of the earlier ruling that RIM infringed on a Nokia patent by including WLAN in its BlackBerry handsets.

According to Nokia the ruling was that RIM could not manufacture or sell any WLAN product without paying royalties first, and so it has filed cases in the US, Canada and the UK to have the ruling enforced - which could mean a sales ban on BlackBerry handsets.

It has to be said the squabble comes at a remarkably bad time for both companies. Nokia is struggling to capture a foothold in the smartphone market, despite recent releases in the form of the Nokia Lumia 920 and the Nokia Lumia 820.

Meanwhile BlackBerry continues to lose ground to the likes of Apple and Samsung, and is heavily relying on the new BlackBerry 10 operating system that was originally slated to appear this autumn but has been pushed back to early next year.

So far RIM has yet to comment on the ruling but has said that it will respond to Nokia in time. Whether a royalty agreement will be reached by the two companies remains to be seen.
