On April 16th, Apple filed a trademark infringement suit against Samsung with the U.S. District Court in North California. If you thought Samsung was just going to stand around, you thought wrong.
Apple originally filed a lawsuit against Samsung because it claimed Samsung's Galaxy S Android smartphones and new Galaxy Tab tablet violate Apple's intellectual property rights in regards to hardware design and user interface. Samsung last week returned the favor and counter-sued Apple, claiming that it has infringed 10 of its patents that have to do with "fundamental innovations that increase mobile device reliability, efficiency, and quality, and improve user interface in mobile handsets and other products".
Samsung now filed another lawsuit against Apple in the U.S.
