Track record





Steve is probably best known for acting as lead counsel in the representation of Dr Tafas in the suit of Tafas v. Dudas, in which a successful challenge was brought against certain regulations to change continuation and claim practice in the United States. The regulations were understood through the patent field to have widespread effects on patent practice, and to increase costs substantially for the maintenance of patent portfolios. For his actions in the case, he was awarded the Case of the Year (2009) by a number of organizations including Managing Intellectual Property. His client, Dr Tafas, won the prestigious Jefferson Medal by the New Jersey Intellectual Property Association, becoming one of the few non-lawyers to ever receive the award.
