A jury at Delaware Federal Court in the US has ruled that Apple’s iPhone has infringed three patents owned by MobileMedia Ideas (MMI).

The infringed patents cover mobile-device technologies such as camera phone technology, which were acquired by the holding firm from Nokia and Sony in 2010.

MMI chief executive Larry Horn said that the firm company could collect substantial damages from Apple. "Our goal is really to license these patents broadly to the market," Horn said.

On the other hand, the US mobile maker is hoping a judge will rule that MMI’s patents are invalid as a matter of law, as well as establishing that there is no adequate basis to find MobileMedia has proven infringement.

MMI was established by subsidiaries of Nokia, Sony and MPEG LA to manage patents added to the venture by Nokia and Sony.

In 2011, a consortium including Apple, Microsoft and RIM purchased Nortel Networks’ 6,000 patents for $4.5bn, while Google lost the auction following an initial offering of about $900m.
