Samsung, a Korean company, told a San Jose jury Tuesday that Cupertino-based Apple is threatening to ruin the culture of Silicon Valley, as Apple tried to hammer home its copycat claims.

Apple may have its work cut out for it to preserve last Friday's $1.05 billion trial victory over Samsung.

Having successfully sued Google for patent infringement, Vringo filed a claim on Thursday against Microsoft for violating the same patents that it acquired from the search engine Lycos.

The Sixth Circuit caught flack from tort reformers six months ago for green-lighting class claims over mold-ridden Whirlpool washing machines. Now the Seventh Circuit has given class action critics more to stew over in a parallel case against Sears--and possibly complicated efforts by Whirlpool's lawyers at Mayer Brown to win Supreme Court relief.

It's almost impossible to exaggerate the obstacles Barclays' lawyers faced in the $13 billion Lehman 'windfall' litigation: claims by three different plaintiffs represented by three powerhouse firms; a judge openly skeptical of the bank's core argument; and a disjointed trial schedule that stretched over six months. Yet in the end the bank prevailed in upholding a deal that helped shape the unfolding of the great recession.

If we keep going at this rate, there soon won't be a prominent securities litigator in New York who's not involved in a suit challenging the bond insurer's restructuring.
