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.

New estimates from ABI Research show that 41.3 million branded tablets were shipped worldwide in the first calendar quarter of 2014.

Apple and Samsung accounted for 71% of the total, putting them well ahead of their competitors.

76.9 million tablets were shipped around the world in the last three months of of 2013, according to figures from the International Data Corporation (IDC). That’s 62.4% up from the previous quarter and a year-on-year increase of 28.2%, although a much lower growth rate than the same quarter in 2012.

Total tablet shipments for 2013 reached 217.1 million units; up 50.6% from the previous year.

The consortium that acquired Nortel’s portfolio of around 4,000 tech patents is now putting those patents into battle.

Those patents were bought in March 2012 for $4.5 billion by the Rockstar Consortium, which included Apple, Microsoft, RIM (BlackBerry), Ericsson and Sony.

While smartphone shipments for the past quarter are reported to have risen by over 38% year-on-year, the growth of tablet sales hasn’t been any less dramatic.

Figures from the International Data Corporation show tablet shipments up 36.7% year-on-year (and 7% from the previous quarter) to 47.6 million units.

Ah, the joys of multiplying by zero. I was reminded of my school maths lessons when I saw a news release from Orange UK this week.

Steve Wallage, Head of Sport Partnerships and Services for Orange UK was quoted as saying “Based on the surge in demand for mobile TV during the Ashes last summer, we expect viewing figures could rocket by at least 74% during the World Cup”.

I loved the film WarGames. I saw it in the cinema when it came out… and developed a minor crush on Ally Sheedy as a result. If you don’t remember the film – or haven’t seen it – the plot centres on a young computer hacker who almost starts World War III while playing an illicit online game of Global Thermonuclear War with a military computer.

It’s time to take sides. Are you with Apple… or are you against them?  Sorry, sitting on the fence is no longer acceptable. Not sure?  Okay, try this one for size. Are you with Google… or are you against them?  Still undecided?

Right – here’s your third choice. Are you with the Rebel Alliance?

It's not often that a news story about the Apple iPhone prompts me to remember a bible verse... but this week was an exception.

The story was in The Washington Post and it was headlined 'Apple's iPhone does well without being the best'. “Very true,” I thought, as I remembered something similar I'd written last summer.

Welcome to the Carnival of the Mobilists #224. If you’re a regular visitor to The Fonecast and have no idea what the Carnival is, this is a summary of the week’s best blogging about all things mobile. It travels the internet, alighting at a different mobile-related website every week.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
