Patent strategy specialist RPX Corporation says one of its subsidiary companies has bought approximately 4,000 patents from Rockstar Consortium.

Rockstar was formed three years ago to acquire around 6,000 technology patent assets from Nortel.

If you listen to this week’s edition of The Fonecast - in which we predict what’ll be happening in the mobile telecoms industry during 2015 - you’ll hear James Rosewell say that BlackBerry’s handset business is doomed. Well, actually that’s not quite true.

The Fonecast predicts 2015: Iain Graham, James Rosewell and Mark Bridge gather round a sapphire crystal ball and make their forecasts for the next 12 months in the mobile industry.

Whose product line won't survive until December 2015? What will happen with the BT/EE merger? Which new features will be introduced by smartphone manufacturers?

It's time for another news-packed mobile industry podcast from TheFonecast.com, starting with the European Parliament's latest ruling on in-car emergency communication.

After that we're talking about Microsoft's departure from the Nook eBook business, Three UK's 4G growth, Acer's tablet-sized phone, EE's rural coverage solution and some interesting new research about mobile-enabled customer service.

We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.
