According to the court filings, Samsung claims that both the iPhone and iPad infringe on 10 of their mobile technology patents, and called for immediate action, along with compensation for damages. The patents in question involve methods for reducing power consumption during data transmission, along with various 3G technologies for reducing errors during transmission.
"Samsung is responding actively to the legal action taken against us in order to protect our intellectual property and to ensure our continued innovation and growth in the mobile communications business," the statement said.
Countersuits are fairly common in this type of a scenario, and while Samsung may just be using it to pressure Apple into settling the dispute, this very public battle might well have Apple looking for an alternate supplier by the time it’s all over.
