Biography

Charles is a patent attorney who focuses his practice on patent prosecution, counseling and dispute resolution. As a registered patent attorney with the United States Patent and Trademark Office, he has managed patent portfolios in several technology areas, including optics, stereoscopic and holographic displays, semiconductor manufacturing, medical devices, telecommunication software, and consumer products. Charles has drafted patent applications, responded to office actions, and appealed to the Patent Trial and Appeal Board (“PTAB”). Since the implementation of American Invent Act in 2013, Charles has represented clients at PTAB for Inter Partes Review cases.

In litigation matters, Charles teams up with trial litigators to handle patent disputes. In collaboration with trial litigators, he has managed various aspects of patent infringement cases, including preliminary injunction, pleadings/motions, infringement and invalidity contentions, claim construction, fact and expert discovery, and trial preparation.

Additionally, Charles has significant cross-border dispute resolution experience, with particular emphasis on China. Charles uses his understanding of China’s patent law, court system, and trial procedures to help clients navigate pitfalls faced by many U.S. litigants, including cultural and language barriers, limited discovery, and potential bias.

Other aspects of Charles’s IP practice include freedom-to-operate studies and commercial transactions involving IP, such as drafting agreements and performing IP due diligence.
