Intellectual Property Expert Witness

IP and market analysis for attorneys

If you’re an attorney faced with trademark infringement issues…or a need to assess patent infringement damages…or addressing a deceptive advertising allegation, Gelb has been there (among other places).

The firm’s two expert witnesses, Gabriel Gelb and Betsy D. Gelb, Ph.D., have assisted attorneys in 30 states on both the plaintiff and defendant sides. Their article on Internet surveys in The Trademark Reporter was favorably quoted in McCarthy on Trademarks and Unfair Competition.

G Gelb

Gabe Gelb’s track record extends over a 20-year period, highlighted by acting as a witness in the precedent-setting trade dress case, Two Pesos v. Taco Cabana case that ultimately reached the U. S. Supreme Court.
