  • Experience

    • Forced a final and favorable settlement for a client on the eve of trial after seven years of litigation. This client was the first defendant in line for trial in a case brought by a non-practicing entity against more than thirty defendants. Tom was instrumental in developing a winning summary judgment motion that ultimately invalidated the patent and resulted in a win for all remaining co-defendants on the case.
    • Achieved client-favorable results in litigations over generic versions of blockbuster drugs tadalafil (brand name Clialis®, $2.3 billion annual sales) and cyclosporine (brand name: Restasis®, $1.4 billion annual sales)
    • Successfully represented Fresenius Kabi USA, LLC in obtaining a rare preliminary injunction in federal district court. The injunction barred our client’s competitor from launching a generic version of its patented formulation of levothyroxine, an injectable thyroid hormone. The District Court for the District of New Jersey granted the injunction on the basis that our client was likely to win its patent lawsuit against its competitor, which was upheld on appeal to the Federal Circuit.
    • Represented a major generic pharmaceutical company in a Hatch-Waxman litigation that found the patent-in-suit invalid as obvious. Litigated successfully through appeal, and pursued recovery on injunction bonds.
    • Obtained a final judgment of invalidity on six patents for major pharmaceutical company client, including multiple successful motions dismissing closely related patents.
    • Won a $2.1 million judgment for a semiconductor company client in a jury trial in the Eastern District of Texas on a patent infringement claim.
