There can be little doubt that the year will be remembered for the smartphone patent wars which raged between companies across courtrooms in the US, UK, Asia and Europe.
Some will say that it was the year of the tablet while others will point to smartphones' becoming mainstream and social media companies' being valued at billions of dollars. But the fact is that for most technology watchers, 2012 will go down in history as the year of the patent wars.
Over the last 12 months Apple has sued Samsung, Samsung has sued Apple, Microsoft has sued Google, HTC has sued Apple, Apple has sued HTC, Mformation Technologies has sued RIM and Microsoft has sued Barnes & Noble. There has been so much legal activity that the term ‘Patent Troll' had to be coined to describe a company that owns patents but doesn't make anything of its own, prefering to use the threat or procedure of litigation to force companies that they say infringe patents to pay licensing fees.
Motorola Mobility -- about to be bought by Google -- files a lawsuit targeting Apple seeking an injunction for infringement of six US patents relating to smartphone technology.
