About Osha Liang


About Us

Founded in 1998, Osha Liang is an intellectual property law firm with a global reach. With offices in Texas, California, Washington, D.C., France, China and Japan, our goal is to assist our clients in protecting and enforcing their intellectual property interests worldwide. The firm prides itself in being one of the most technically and legally proficient IP firms in the world, delivering to our clients the highest level of quality and customer service.

Osha Liang has expertise in worldwide patent and trademark procurement, portfolio management, licensing, acquisition, due diligence, opinions of counsel, litigation, and strategic IP counseling, among other areas. We are recognized as one of the top IP firms in the nation based on the number of patents issued.

We believe in a team approach when servicing our clients. At Osha Liang, no partner “owns” a client. Through open discussion with each client, an appropriate team is assembled within the firm based upon experience and technical backgrounds to meet the client needs in each particular matter. Although a lawyer may be appointed as a primary point of contact, each project is staffed to yield the highest quality work product.

We represent clients throughout the Americas, Europe, and Asia, file patent applications in every industrialized country in the world, and conduct business in a variety of languages, including: English, Italian, Spanish, French, German, Japanese, Chinese, and Taiwanese.

We are particularly proud of the broad range of technical skills possessed by our professionals. One of the many unique and forward-looking aspects of the firm’s practice, which is designed to enhance the technical skill level while providing first-rate legal services, is our Patent Agent Program.

Osha Liang’s Patent Agent Program is unique and extremely effective in developing a technically and legally savvy team. Unlike most firms that recruit solely from law schools, we actively recruit science and engineering graduates from top-rated universities. These individuals are then apprenticed in the art of patent practice through the use of practical on-the-job training and weekly lectures. Eventually, these Patent Engineers are encouraged to sit for the United States Patent and Trademark Office registration exam to become licensed patent agents. Under supervision, these patent engineers and patent agents provide exceptional value to clients in terms of both technical knowledge and cost effectiveness. Graduates of the program have the option to attend local law schools on a part-time basis with tuition assistance provided by the firm.

Our Patent Agent Program, multilingual staff, foreign-licensed attorneys, worldwide network of foreign associates, and in-depth knowledge of international rules and foreign business cultures make our firm one of the most diverse and uniquely experienced intellectual property practices in the world.
