Samsung are now going after Apple's latest and greatest - the iPhone 5, with the South Korean company alleging that the iPhone 5 infringes on patents that they hold. Samsung commented on the news to Reuters, where they said:
We have little choice but to take the steps necessary to protect our innovations and intellectual property rights.
TechCrunch pushed Samsung for a comment for more details, where they responded with:
We have always preferred to compete in the marketplace with our innovative products, rather than in a courtroom. However, Apple continues to take aggressive legal action that will restrict market competition. Under these circumstances, we have little recourse but to take the steps necessary to protect our innovations and intellectual property rights.
It looks as though 4G LTE patents are going to come into play here, as Samsung did say that if Apple were to release the new iPhone with LTE compatibility that they would "immediately sue them".
