Diserio Martin O'Connor & Castiglioni LLP


A trademark can embody many things – the promise of quality, an indication of source, and the backing of a company whose reputation has been built through years of dedication. These intangible qualities are an immensely valuable asset. Our attorneys are experienced in protecting and asserting your rights in every context, whether it’s through enforcement against infringers, defending attacks on your brands, registering your trademarks with the Patent and Trademark Office, negotiating licenses, attacking counterfeiting and gray market concerns, or addressing use of your marks on the internet.
