Nokia is back on the war path against Apple.
It has filed yet another complaint in the US, claiming that Apple has infringed Nokia's patents in almost all of its mobile phones, portable music players, tablets and computers.
In a statement, Nokia said the seven patents in question relate to Nokia technology now being used by Apple to create features in its products - in multi-tasking operating systems, data synchronisation, positioning, call quality and the use of Bluetooth accessories.
The latest ITC filing means that Nokia has 46 patent claims against Apple.
"Apple must stop building its products using Nokia's proprietary innovation," it added.
The complaint followed last week's decision by the ITC that found no violation in an earlier complaint.
However, according to Intellectual Property blogger Florian Mueller, this particular claim isn't overly beneficial for anyone.
"As we all know the ITC decision on Friday wasn't good for Nokia but today isn't much better either," he told TechEye.
"To reference the football, Apple and Nokia are currently facing a goalless draw - it's a nil/nil outcome. Nokia is frustrated that everything is taking so long with Apple considering it filed its first complaint in a Delaware court in 2009 and it's still waiting for a decision."
Today's decision, Mueller argues, looks as though Nokia is trying talk up its ranks in Apple-aimed chest-beating: "We have 12,000 patents, you have 2000, we work in the same industry and with that in mind our big number shows you'll have to pay us. We've not yet seen the escalation of this, there is serious money at stake and it's an epic battle."
