More lawsuits are being filed against the mobile phone makers.

Nokia and Apple are already involved in some lawsuits targeting each other.

Apple recently filed a big lawsuit against HTC related to Google Android powered devices.

Now, a company named SmartPhone Technologies is targeting several mobile companies claiming patent infringements.

The lawsuits have been filed against some well known companies like Apple, AT&T, RIM (Research in Motion), Samsung, Sanyo, LG and Motorola.

The biggest claim is made against the Apple iPhone device. The lawsuit claims that Apple infringes on six of the companies patents.

Apple incidentally recently stated that they are currently facing around 47 patent infringement related lawsuits most of which were filed last year.
