Samsung Calls In Experts to Prove It Didn’t Violate Apple Patents

The Apple (NASDAQ:AAPL) versus Samsung (SSNLF.PK) trial just got a lot more technical. AppleInsider reports that Samsung has called on several computer scientists and other technology experts to testify that the company did not violate Apple’s patents.

Apple’s lawsuit names five patents that the California-based technology firm claims the South Korean smartphone maker violated and that the company is owed $2 billion for the technology covered in the patents. Samsung counters that Apple has violated two of its patents and owes $7 million. Each side gets 25 hours to present evidence, according to court documents.

This is the second time Apple has sued Samsung, alleging patent violations. Many of the same parties are involved in the San Jose, California, court. Even the same judge is overseeing the new case.

One feature that Apple claims Samsung stole is the slide-to-unlock function, Re/code and several other news outlets report. On Monday, senior UI designer Youngmi Kim took the stand to testify about that particular feature. The designer has worked for Samsung since 2004. She said through a translator that it makes no sense for Samsung to copy Apple, since they want to differentiate their products.

Another expert witness, Kevin Jeffay, a professor of computer science at the University of North Carolina at Chapel Hill, said that Apple’s patent is more limited than it claims in the lawsuit, CNET reported in its coverage of the trial on Tuesday.

If it seems like this legal battle between the world’s two largest smartphone companies sounds familiar, it’s because it’s been ongoing since 2011. CNET has a good overview of it in its FAQ on the lawsuits.

The short version is that it started when Apple filed the first lawsuit against Samsung, claiming that Samsung’s devices looked too much like Apple products and alleging that Samsung had violated Apple’s design patents, according to court documents. The latter countersued. That case went to trial in August 2012. The court ruled in Apple’s favor and Samsung lost the countersuit. In March 2013, the judge ordered a new trial in that month so that money awarded in the form of damages could be changed according to court documents. In November of that year, a jury awarded Apple additional damages of about $290 million. Apple also sued again in September 2012, a month after the original trial, alleging that Samsung violated Apple’s patents.

Basically, Apple keeps claiming that Samsung is violating its patents. Samsung claims that Apple is trying to target the company to suppress competition.

In this latest trial, which started on March 31, Samsung is countering Apple’s claims of patent violations with expert testimony about how Samsung has not violated patents by explaining how both Samsung and Android technology work. The company has also claimed that since it does not make the Android operating system its phones run on, it is not responsible for its features. The trial is expected to end sometime next week.
