Patents are becoming increasingly important as a valuable asset and useful business tool. Often, patents are a company’s most valuable asset. We advise our clients on all aspects of patent law, including identifying and developing an effective and economically efficient patenting strategy, building and maintaining a world-wide patent portfolio that meets business objectives, clearing new products to avoid law suits, enforcing clients’ patent rights or defending against infringement law suits, helping negotiating license agreements, or conducting due diligence investigations. We have also developed a network of highly qualified foreign associates who are experts in local patent laws, to assist our clients in foreign countries no matter where their businesses or markets take them.

We bring many years of patent law experience to our clients’ patent needs, aided with our prior engineering and corporate experience. We strive to stay abreast of our clients’ business objectives and partner with our clients closely to understand their business and legal goals. We are committed to maintaining a high-standard of client services throughout the patenting process and providing quality patent law advice with the dedication expected from a trusted business advisor.
