Samsung makes good on threat of patent suit against iPhone 5

Apple's chief foe in the mobile sector and the courtroom goes after the new iPhone, alleging the new smartphone infringes on eight of its patents.

Fresh off a courtroom victory against Apple today, Samsung filed another legal salvo against its chief foe.
The Korean electronics submitted an amendment to a lawsuit originally filed in April against Apple, adding the iPhone 5 to a list of devices that includes the iPhone 4, iPhone 4S, iPad 2, and the new iPad that Samsung accuses of infringing on several Samsung patents.
Samsung reportedly threatened to sue Apple last month for patent infringement over its then reported use of long-term evolution (LTE) connectivity in the next-generation smartphone. While the new iPhone's debut last month confirmed that Apple's new device featured access to the the speedier fourth-generation wireless networking -- for which Samsung holds numerous patents -- Samsung's latest lawsuit did not address the LTE patents
A Samsung representative told CNET this evening that the eight patents in question include six utility patents and two standard essential patents unrelated to its LTE patent portfolio (see filing below).
Echoing previous statements made in the patent dispute, Samsung said, "we have little choice but to take the steps necessary to protect our innovations and intellectual property rights."
CNET has contacted Apple for comment and will update this report when we learn more.
