He works with inventors to file new patent applications, defends those inventions in all types of Patent Office proceedings (including PTAB challenges), tries patent cases in the courts, argues for appellants and appellees in patent appeals at the United States Court of Appeals for the Federal Circuit, and brings and defends patent proceedings at the United States Supreme Court.

In February 2011, Mr. Greenspoon helped win a patent jury trial for a first-tier automotive supplier client against its direct competitor, performing most of the direct and cross examinations for his side.

Mr. Greenspoon has argued numerous cases before the Courts of Appeals for the Fourth, Eighth and Federal Circuits. Since co-founding the Firm, he argued the winning appeals in D’Agostino v.

The Columbia Science and Technology Law Review published his co-authored article "Don't Assume a Can Opener: Confronting Patent Economic Theory with Licensing and Enforcement Reality" in June 2011.
