r. Wierzbowski's practice focuses on derivative and securities class actions brought on behalf of defrauded investors, and the prosecution of patent infringement suits on behalf of patent-holders.

As a member of the Firm’s patent litigation group, Mr. Wierzbowski is currently prosecuting cases on behalf of Anvik Corporation against Nikon, Sharp, Samsung, and many other large electronics companies relating to Anvik’s patented technology for manufacturing the displays used in flat panel televisions, computer monitors, and other devices. He is also a member of the team prosecuting a patent infringement suit on behalf of Xpoint Technologies, Inc. against Intel, Microsoft, Dell, Hewlett-Packard, and other large computer companies relating to Xpoint’s patented One-Button Restore™ technology for restoring the operating system, applications programs, and user data on a computer after the computer is corrupted or damaged.

Mr. Wierzbowski also currently represents institutional investors in a securities class action against Schering-Plough and others, alleging that Defendants misrepresented and withheld the financially-devastating results of the ENHANCE drug trial, which called into serious question the benefits of Schering-Plough’s cholesterol-lowering drugs ZETIA and VYTORIN. Mr. Wierzbowski is also a member of the team prosecuting a securities fraud suit against Merck and others, which arises out of Defendants’ misstated belief in the safety of Merck’s pain-killer VIOXX. Plaintiffs successfully appealed the dismissal of the Merck action to the Third Circuit Court of Appeals, and that case is now before the U.S. Supreme Court.

At BLB&G, Mr. Wierzbowski has also been a member of the teams that successfully litigated derivative actions on behalf of public pension funds against the individuals involved in stock option backdating, including the UnitedHealth, Monster Worldwide and Progress Software cases. For instance, in UnitedHealth, Plaintiffs achieved wide-ranging corporate governance reforms and successfully recovered hundreds of millions of dollars from the individual Defendants in the largest derivative recovery in history.
