Dr. Woodward Yang, an electrical engineering professor at Harvard, was called by Samsung as an expert witness. on Tuesday In his testimony, Yang said Apple’s products use Samsung-patented features for mobile devices, including the process for seamlessly emailing photos.

Additionally, one of Samsung’s designers testified that she had not based Samsung’s Galaxy S smartphone icons on Apple’s own design, despite notable similarities.

Together, Apple and Samsung control more than half of worldwide smartphone sales. The U.S.-based Apple accuses the South Korean Samsung of copying the design and some features of its iPad and iPhone, and is asking for a sales ban in addition to monetary damages. Samsung, which is trying to expand in the United States, says Apple infringed several patents, including some for its key wireless technology.

This week, Apple concluded presenting evidence regarding its own patents, and Samsung began calling its own witnesses.

Yang said Samsung’s patents were filed before the introduction of the iPhone in 2007. He focused on patents covering smartphone features, not wireless technology, one of which covers technology for easily finding photos in an album.

When questioned by Apple attorney Bill Lee, Yang said he had not seen evidence that Samsung actually used any of those features in its own smartphones.

Later in the day on Tuesday, Samsung called designer Jeeyuen Wang, who said she and a large team worked for three months to create Samsung’s own unique icon designs for Galaxy S phones. Apple attorney Michael Jacobs showed Wang internal Samsung documents with her name on them that contained references to Apple icons, but under questioning from Samsung attorney John Quinn, Wang said some of those documents were created well after Samsung had finished its own designs.

Hoping to invalidate some of Apple’s patents in the case, Samsung also presented evidence this week that Apple has patents that cover technological advances, like multi-touch, that had already been developed before Apple claims to have invented them.
