Our runners up for Litigator of the Week include Willkie Farr & Gallagher white collar partners Randall Jackson and Michael Schachter, who won acquittal for their client Jean Boustani on all charges stemming from an alleged $2 billion fraud and kickback scheme. After a six-week trial in U.S. District Court for the Eastern District of New York, a jury rejected all charges related to alleged bribery of officials in Mozambique. (Check out my story about the case here.)

Orrick, Herrington & Sutcliffe's Eric Shumsky scored two appellate wins in two days. Arguing on behalf of Twitter, he convinced California's First District to uphold a lower court decision denying class cert in a potentially huge discrimination case against the social media company.

Demonstrating impressive range, Shumsky also prevailed for Donghee America in a patent fight before the U.S. Court of Appeals for the Federal Circuit. The appellate court upheld the lower court's grant of summary judgment of non-infringement involving patents for manufacturing plastic fuel tanks.

A Kirkland & Ellis team led by John O'Quinn and John Hartmann prevailed before the U.S. Court of Appeals for the First Circuit on behalf of two private equity funds, Sun Capital Partners III and Sun Capital Partners IV, in a decision with broad implications for private equity investments in distressed companies. Reversing a lower court decision, the appellate panel held that the funds were not jointly and severally liable for a bankrupt portfolio company's multiemployer plan withdrawal liability.

Steven Derringer and John Hughes of Bartlit Beck won a $137 million verdict for Meso Scale Diagnostics in a patent fight against Roche Diagnostics involving electrochemiluminescence technology. After a six-day trial in Delaware federal court, a jury deliberated for less than two hours before finding that Meso Scale held an exclusive license to the patent claims at issue and that Roche infringed all of those claims.

Sullivan & Cromwell partner Jeff Scott on behalf of Barclays Bank and Williams & Connolly's Nicholas Boyle on behalf of HSBC won a major ruling from New York's highest court in a fight with nearly $1 billion on the line. Both banks faced RMBS repurchase claims asserted by Deutsche Bank National Trust Company as the trustee for RMBS securitization trusts.

The court held that the claims were time-barred, concluding that they were subject to California's four-year statute of limitations, and not New York's six-year limitations period. Sweeter still, the court also awarded the defendant banks' costs for the appeal.
