Safeguarding Your Intellectual Property Rights

We advise individuals and businesses on all aspects of intellectual property, including:


You must obtain a patent from the U.S. Patent and Trademark Office (USPTO) to protect your innovations. A patent gives you an exclusive right to use or license an invention and bars competitors from doing so. However, securing a patent is challenging because you must demonstrate that your invention is new, useful, and non-obvious. 

Our patent attorneys work to understand our clients’ innovations and craft the broadest possible patent claims. We have the legal knowledge and technological proficiency to help you prosecute your patent claim with the USPTO. We also assist clients with international patent registrations under the Patent Cooperation Treaty (PCT).

A patent is granted for new designs, devices, or methods that have not been publicly disclosed. If an invention has already been disclosed to the public, it may be difficult to obtain patent registration. Therefore, it is recommended to file a patent application within one year of the public disclosure. 

One of the roles of patent registration is to maximize profitability. It is important to thoroughly evaluate whether the patent you intend to register has sufficient profitability or is feasible to be realized. Patent registration incurs higher costs and involves more complex procedures compared to other forms of intellectual property registration, so the assistance of a patent expert is often necessary.


The strategic use of trademarks and service marks can help to establish your brand identity. By obtaining a proper trademark registration, you have the right to bar others from using that mark. 

You can depend on our Dallas IP attorneys to guide you through all phases of brand identification and trademark selection. We regularly conduct searches of the trademark registry, handle the registration process, and also prepare applications for the international registration of trademarks coordinating with local counsel. To register a trademark in the United States, you need to obtain it from the United States Patent and Trademark Office (USPTO).

Based on our extensive experience in handling numerous trademark applications, our law firm can guide you through all stages of the U.S. federal registration process and provide you with in-depth knowledge of U.S. trademark law. Additionally, we offer trademark pre-filing search services to minimize the risk of refusal by USPTO examiners. We assist businesses in various fields, ranging from cosmetics, hair products, and beauty items to clothing brands, bags, jewelry, restaurants, coaching services, and IT services, with their trademark application needs.

U.S. Customs and Border Protection (CBP)

We also provide services for brand registration with the U.S. Customs and Border Protection (CBP) Intellectual Property Right Recordation Service. By registering your trademark with CBP, you can proactively prevent the importation of counterfeit or infringing products into the United States. Our law firm supports you through every step, from brand registration with CBP to educating CBP officers on product identification.

Trade Secrets

Our firm helps domestic and foreign businesses in Texas protect their methods, formulas, processes, and other confidential information. To be considered a trade secret, you must take reasonable steps to keep the material confidential. Our firm can help you protect your trade secrets through well-conceived noncompete and nondisclosure agreements or seek remedies for trade secret theft in state and federal courts if necessary.


Copyrights protect ideas fixed in a tangible medium such as fiction, non-fiction, poetry, artwork, illustrations, Fabric, architecture, design, articles, periodicals, computer programs, software literary, artistic, and musical works, including sound and video recordings. Copyright registration gives an owner the right to use, license, or exploit the work in other ways and exclude others from using the work. Although registration is not required to establish a copyright, registration is necessary to have standing for a legal action in federal court. We assist clients with completing and submitting copyright applications for their original work, advise businesses that have commissioned works for hire, and design strategies for copyright acquisitions, often in the context of mergers and acquisitions.

The Value of IP Property Assets

The main benefits of securing intellectual property protection are the power of exclusivity and protection against infringement claims. At the same time, IP rights are valuable assets that can open new markets and provide additional sources of revenue. At Sul Lee Law Firm, we design forward-looking IP strategies that contemplate the purchase, sale, and licensing of intellectual property.
