Last week, in an unexpected turn of events, Nokia filed a brief in support of Apple in their lawsuit against Samsung. The brief was filed under seal but a summary provided with the brief indicates that Nokia believes Judge Koh wrongly denied Apple’s request for permanent injunction of Samsung’s products. Judge Koh previously ruled that Apple had not established a “casual nexus” between its patented feature and the demand for its phones. Nokia’s summary also reflects the belief that this court ruling could be damaging to the patent protection landscape in theUnited States. So far, no other companies have joined in on this fight with Apple.
