Samsung has already sued Apple over patent infringements and now they're attempting to get a full out ban of iPhones and 3G iPads in the Netherlands. They've sued Apple on infringement of four patents and not only want a ban but a full retail recall of any device that uses 3G technology.
The patents involved are standards-essential patents. They are incorporated as internationally excepted standards and the patent holder (Samsung) is obligated to grant licenses to third parties. Florian Mueller, an active patent consultant, believes that an injunction won't happen unless Apple refuses to pay up if royalties are owed to Samsung.
