Google in successfully securing a complete dismissal in a patent infringement challenge brought by Data Engine Technologies in the District of Delaware.  Data Engine alleged that Google Sheets infringed patents which purportedly covered the Quattro Pro for Windows® spreadsheet program sold by Borland Software Corporation in the 1990s.  Chief Judge Leonard P. Stark found that the asserted claims were directed to patent-ineligible subject matter and thus invalid, and granted Google’s motion to dismiss.  This matter originally began as a six-patent case against Google, which Kasowitz successfully reduced to three patents.

Mallinckrodt in a patent infringement matter involving Mallinckrodt’s patent for opioid painkiller Opana ER.  The District Court of Delaware upheld the validity of Mallinckrodt’s patent, rejecting arguments from Amneal Pharmaceuticals and Teva Pharmaceuticals.  Amneal and Teva defended their potential generics, alleging that prior art anticipated Mallinckrodt’s patent.  In his opinion, the judge found that neither a 1957 academic paper, nor a 2005 patent application, anticipated the process or product described in the patent.

U.S. Bank and HSBC Bank USA, as trustees of numerous residential mortgage-backed securities (RMBS) trusts that lost billions of dollars after the financial crisis.  Building off of our representation of the Federal Housing Finance Administration, Kasowitz has been the market leader in RMBS putback litigation ever since the pervasive nature of the low-quality mortgage loans underlying private-label RMBS first became exposed. With actions against Deutsche Bank, Nomura, Morgan Stanley and others, Kasowitz has both litigated the main cases – including the NY Court of Appeals’ ACE 2006-SL2 decision and the First Department’s NHELI decision now pending before the Court of Appeals – and represented trustee plaintiffs in the largest number of cases in the consolidated Part 60 proceedings.
