“A financial expert said Apple Inc has overstated Samsung Electronics Co Ltd’s profit margins for mobile products, an issue that goes to the heart of damages in the high profile patent trial between the two tech companies,” Dan Levine reports for Reuters.

Levine reports, “Earlier this week, Apple expert Terry Musika said Samsung earned 35.5 percent margins from mid-2010 through March 2012, on $8.16 billion in U.S. revenue.
