Samsung's claiming that Apple committed five patent infringements in Seoul, two in Tokyo and three in Germany. Rather than target the design and software of the devices, which is what Apple claims Samsung infringed on, the South Korean manufacturer is going after network-focused features.
Specifically, Samsung claims Apple overstepped on patents related to reducing data transmission errors in Wideband CDMA networks, tethering phones to PCs and reducing power consumption on HSPA networks.
"Samsung is responding actively to the legal action taken against us in order to protect our intellectual property," Samsung said in a statement.
Patent infringement cases are common in mobile, but Samsung and Apple are unique because Apple is Samsung's largest customer for components, a relationship Apple's COO Tim Cook said he expects to continue on the company's second-quarter earnings call.
"Separately from this, we felt the Mobile Communication Division of Samsung crossed the line," he said on the call. "And after trying for some time to work the issue, we decided we needed to rely on the courts."
"I think the user appreciates that Apple can take full responsibility for their experience, whereas the fragmented approach turns the customer into a systems integrator and few customers that I know want to be a systems integrator," Cook told investors.
The WSJ says both are collecting the data to build an enormous database of location to target users with location-based services and advertising, both potentially lucrative markets.
We're rooting for the latter -- RIM needs to keep its mobile momentum going after the launch of its first tablet, the Playbook, this month. (See RIM PlayBook: LTE & HSPA+ Versions Coming.)
