About the Firm

Helping you protect, defend, and capitalize on your intellectual property.

Greenberg & Lieberman is an Intellectual Property Law Firm, which is registered to practice before the U.S. Patent and Trademark Office (USPTO). Located in Takoma Park, MD, a suburb of Washington, DC — we serve clients nationally in the areas of Patents, Trademarks, Copyrights, and Computer Law. Our attorneys’ collective experience total’s decades of practice in the field. We have served well over 15,000 clients.

As you would expect of an intellectual property law firm, our work revolves around patents, trademarks, and copyrights. Because of our proximity to the USPTO, all documents are filed by hand. We also perform hand searches of PTO records when necessary.

As you might not expect from an intellectual property law firm with a national client base, when you call Greenberg & Lieberman you will speak directly with an attorney, not a clerk or an order taker. In fact, when you call the person who picks up the phone will quite often be an attorney or paralegal.

All work is performed under a covenant of strict confidentiality.

We are qualified specifically in mechanical, biochemical, electrical, and the computer fields. However, we can handle applications in nearly every field. Our staff members are not only good legal practitioners, but also have a very broad and diversified education and experience.

In the area of trademarks, service marks and franchising, we have extensive experience in a wide variety of fields, including clothing, fashion apparel, makeup and design, computers, electronics and communications, and small business. Our attorneys will outline the available strategies and counsel you as to your best course of action.

As we are highly sophisticated in today’s communication technology, it does not matter where your business is located. We are capable of communication through any medium available, and a live person is always available on our toll free number in order to meet your needs.
