Trusted, Trial-Tested Intellectual Property Litigation Attorneys

While it is important to seek legal recognition of your intellectual property, you also need to be prepared to defend it against infringement attempts. That is where the attorneys at Astor Weiss Kaplan & Mandel LLP come in.

Our firm litigates intellectual property cases concerning patents, trademarks and copyrights in federal courts. We also have experience litigating before the U.S. Patent and Trademark Office Trademark Trial and Appeal Board. At the same time, we have an active practice of trademark prosecution, which involves obtaining federally registered trademarks for clients.

Notable Judgments On Behalf Of Clients

Intellectual property cases almost always settle without a trial. Our experience in both trademark prosecution and trademark litigation gives a depth of knowledge and experience that strengthens our services in both areas.

Protecting Clients’ Online Assets

With the development of the internet, the use of an online domain name is very important to businesses. An example of a domain name is “” – the domain name used to access this website. Domain name disputes often include disputes over a trademark, and we have extensive experience in handling disputes over domain names in court.
