Nokia has just issued a press release stating that in an effort to “protect its innovations and intellectual property”, the company has filed patent lawsuits against rival smartphone makers HTC, RIM and Viewsonic that cover 45 of its patents.

The Finnish mobile maker says that the companies infringe a number of its standards essential patents, filing suits to “end the unauthorized use of our proprietary innovations and technologies, which have not been widely licensed.”

According to the release, the patents referred to in the lawsuit have already been licensed by over 40 companies. It also lists where and with who it has filed its complaints, noting 45 individual patents have been named in its complaints in Mannheim and Munich in Germany, and Delware in the US:

Nokia’s actions include a complaint to the US International Trade Commission (ITC) against HTC, suits against HTC and Viewsonic in the Federal District Court of Delaware, US, against HTC and RIM in the Regional Court in Dusseldorf, Germany and against all three companies in the Regional Courts in Mannheim and Munich, Germany. In total, 45 Nokia patents are in suit in one or more of the actions.

As for the patents? FossPatents grabbed a list of the patents in question (they can be found at the foot of the post).

Nokia accuses HTC, RIM and Viewsonic of using technologies named in its patents to enable hardware capabilities such as “dual function antennas, power management and multimode radios”, but also in its software features, including “application stores, multitasking, navigation, conversational message display, dynamic menus, data encryption and retrieval of email attachments on a mobile device.”

While Nokia has been the subject of its fair share of patent lawsuits, it has enjoyed success licensing its patents to some of its rivals, including Apple.

In June 2011, Nokia and Apple finally settled all of their patent disputes, resulting in an agreement that saw the withdrawal of all complaints filed by both companies with the US International Trade Commission.

The agreement saw Apple make a one-time payment, followed by continued royalty payments.
