Apple claimed that the Samsung Galaxy Tab is a copy of the iPad in style and design, with charges focusing on the fact that Samsung allegedly copied Apple's touchscreen technology used on products like the iPod touch, the iPhone, and the iPad. Samsung's counter-claims are on of a slightly different nature, as they involve patent infringement on a component level. See, Apple uses Samsung products in their iPhones and iPads for 3G capabilities. Things like transceiver chips, memory chips, and application processor units are made and sold by Samsung and bought by companies like Apple. According to The Wall Street Journal, Samsung demanded that Apple pay additional royalties for the components that Apple uses. On the other hand, Apple is suing Samsung for outright theft of design as a whole.
