Patent Prosecution

Interacting with the Patent and Trademark Office (PTO) is just part of the process followed to successfully prosecute a patent application to issuance as a patent. Our attorneys are experts at interacting with the inventors and in-house counsel as well. The quality of the patents we obtain is a result of the unique blend of the technical expertise of our attorneys with their excellent communication skills. The technical expertise of our patent attorneys ranges across the spectrum of technical disciplines, including electrical engineering, chemical engineering, and computer science. The firm prides itself in consistently obtaining meaningful patent protection for its clients with a thoughtful combination of efficiency and tenacity.

International Patent Lawyers

We are adept at using the Patent Cooperation Treaty (PCT) to obtain patent protection in member countries, and we have the network of agents necessary to enter the national phase of a patent application under the treaty. We have also used the Patent Prosecution Highway, to help speed the issuance of patents in various countries.

Patent Counseling

Understanding the risk associated with a patent requires an ability to carefully dissect the history of the patent and the scope of its claims. Our attorneys are experts at counseling clients on whether a product infringes a patent and on issues of patent validity. We can provide right-to-use opinions in advance of product investment, infringement and validity due to diligence in advance of litigation, and infringement and validity analysis in response to cease and desist letters and threatened or actual litigation. Our Dallas patent lawyers can also assist clients in developing, marketing, and enforcing patent portfolios.
