Samsung has countersued Apple for the infringement of 5 patents, this in response to Apple's suit against Samsung for patent and trademark violations filed earlier this week.

"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,"

Apple's lawsuit seemed focused on preventing Samsung from copying the look and feel of iPhone and iPad in the Galaxy S line of tablets and TouchWiz skins. Samsung's seems focused on trying to match the patent portion. It will be interesting to see how they respond to the trademarks.

Anyone else thinking that if they continued to innovate, they wouldn't be facing the trademark charges?
