Sam has served as trial counsel and argued dispositive and Markman motions for litigations having million- and billion-dollar markets at stake. He recently Sam obtained a favorable Markman ruling in case involving a drug having annual sales of over $200 million, causing the patentee to stipulate to non-infringement. Sam also served as trial counsel in a dispute involving tamper-resistant OxyContin® where the Carlson Caspers trial successfully invalidated all claims. This case was affirmed by the Federal Circuit. Sam’s other ANDA litigation experience includes cases involving small molecules, formulations and methods of use patents covering, among others, proton-pump inhibitors, phenidate drugs, combination therapies, sleep aids and oncology drugs.

Sam has substantial experience monetizing intellectual property outside of litigation. For example, he has lead negotiations on behalf of a Fortune 500 company to acquire intellectual property rights to platform technology that is projected to serve as the foundation for a multibillion-dollar research program in the life sciences space. In another matter, Sam led an initiative to create an out-licensing program for technology in the bioagricultural field.  The first license agreement executed for the program was valued at over $25 million. Sam also has led negotiations involving research collaborations, intellectual property licenses, non-disclosure agreements, and material transfer agreements.
