[Patent] Samsung countersues Apple for patent violations

Relative articles:
Samsung countersues Apple for patent violations
Samsung files additional patent lawsuits against Apple in California
Samsung now countersuing Apple in four countries on three continents

What is seemingly unusual is that Samsung didn’t file the lawsuit in America, but instead filed lawsuits in Seoul, South Korea (5 patent infringements), Tokyo, Japan (2 patent infringements), and in Manheim, Germany (3 patent infringements).

The first seven patents are related to communications standards such as W-CDMA (UMTS) while the other three patents are user interface patents.
