Apple Inc. has announced that it has filed a patent-infringement lawsuit against Nokia Oyj in the UK as part of a broader battle between the two companies regarding smartphone technology, BusinessWeek reports.
The complaint, which was filed recently in the UK High Court of Justice Chancery Division, is related to patent-infringement claims made by Apple against Nokia in the U.S. in December, Apple spokeswoman, Kristin Huguet, told the news provider.
A spokesman for Nokia, Mark Durrant, called the lawsuit an "unsurprising development" and said "it changes nothing in the fundamentals of the matter, which are rooted in Apple's refusal to respect Nokia's intellectual property and attempt to free-ride on the back of Nokia's innovation."
The dispute initially began in October, when Finland-based Nokia filed a lawsuit claiming Apple had infringed on 10 of its patents. The lawsuit demanded all royalties on iPhones sold since their 2007 introduction, the news provider said.
The specific UK case is based on nine patents that are already a part of lawsuits in the U.S., and Durrant told the news provider that "though litigation is always a last resort for Nokia, the company will continue to defend itself to the utmost."
