The Apple v. Samsung trial gets underway today. Apple is suing Samsung for copying patents and design elements of the iPhone. In the lead up to today, paperwork including iPhone and iPad prototypes that never made it to the sales floor were submitted as evidence. All Things D notes some last-last minute entries into the files:

Among the many filings on Saturday was a document with dozens of sketches and prototypes for both the iPhone and iPad. Some had already been included in earlier filings, but Saturday’s collection was particularly extensive… On the iPad side, there were iPads with square corners and iPads with round corners. Earlier filings showed Apple considering a kickstand for the iPad.

If Apple has its way, Samsung will not only have to shell out $2.5 billion, but it will be forced to tweak the look and feel of some of its phones. If Samsung comes out victorious, more “copycat” phones and competition could give Apple a run for its money.

And then there’s Google, whose lawyers will be attending the trial as spectators to search for clues on possible future litigation by Apple. The Wall Street Journal reports: “The Apple-Google brawl extends far beyond the courts, with both companies racing to develop new features, digital-content offerings—including books and music—and services like maps.” In other words: WORLD DOMINATION!
