Representing plaintiffs and defendants in IP disputes
Although proper registration of patents, copyrights, and trademarks is an important part of any business, it does not prevent all legal conflicts. The rapidly expanding global economy has made many American companies vulnerable to infringement in China and throughout the developing world. Widespread use of the Internet has also exposed large and small businesses to IP rights violations.

At Wang, Hartmann, Gibbs & Cauley, PC, we serve U.S. companies and foreign business interests in intellectual property litigation involving patent law, trademark law, copyright law, and unpatented trade secrets. Our firm represents a wide range of clients in cases involving computer technology, e-commerce, mechanical engineering, and aerospace.
