Samsung Electronics has fired its major salvo in the high-stakes patent battle with Apple Inc. (NASDAQ:AAPL), accusing the latter of infringing on its (Samsung's) patents.
The Korean electronics giant, which started its defence in the trial this week, called Harvard University professor, Woodward Yang to the witness stand on Tuesday.
The professor of electrical engineering testified that Apple's iPhone, iPod and iPad infringed on the Korean handset maker's patents. Incidentally Apple is suing Samsung for violating its design copyrights and imitating its mobile devices while designing its Galaxy range of phones.

Yang said that Apple’s iPhone 3G, iPhone 3GS, iPod Touch fourth generation, and the iPad2 had infringed on features on Samsung’s phone related to scrolling through images, and sending messages with photographs. He also testified that Apple's products had infringed on the Korean company’s photo indexing patent and that for playing MP3 music files.
This is the third week of the high-profile trial between the two companies, which are fighting at least a dozen court battles across four continents, accusing each other of patent violations, monopolistic practices as they try to gain dominance in the $200-plus billion smartphone market.
In the cross examination of Yang that followed, Apple lawyer William Lee brought out that photo scrolling feature had not been used by Samsung on its phones in the last three years.
On Monday, the Korean company had called in two computer scientists to dispute the Cupertino-based company's claim about the originality of its patents.
