Lawyers for Apple Inc. and Samsung Electronics Co. have narrowed down their cases in advance of a federal patent trial set to begin March 31.

In court filings Tuesday, the companies provided a final list of infringement claims and accused products for the upcoming trial, which focuses on more recent phones and tablets than their 2012 showdown. That trial ended in a $1 billion win for Apple and its legal team from Morrison & Foerster and Wilmer Cutler Pickering Hale and Dorr.

The 10 Samsung products targeted by Apple include Galaxy Note, Galaxy S III and a Galaxy tablet. The Apple products accused by Samsung include the iPhone 4, 4S and 5, the iPod Touch (4th and 5th generation) and the MacBook Pro. Samsung is represented by Quinn Emanuel Urquhart & Sullivan.

U.S. District Judge Lucy Koh in San Jose ordered a narrowing of the case beginning last April to simplify the presentation for the jury.

Among the features at issue are Apple’s unified-search, slide-to-unlock, data synchronization, and data tapping functions. Samsung alleges infringement of patents for recording and reproducing digital image and speech and for remote video transmission among others. Unlike the previous go-round, there are no design patents at issue.

On his blog Foss Patents, IP analyst Florian Mueller pointed out that both parties “tried hard to accuse each other’s latest and greatest products,” but the pace of patent litigation has restricted this 2014 trial to 2012 and pre-2012 products—now light years away in terms of technological advances. The list of products will be subject to damages and injunctive relief.
