Charles focuses his practice on all aspects of patent law, including patent prosecution, counseling and patent dispute resolution. Charles is a registered patent attorney with the United State Patent and Trademark Office and has managed patent portfolio for a wide range of technology areas, including optics, stereoscopic and holographic displays, semiconductor manufacturing, medical devices, telecommunication software, and consumer products.  He 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 has teamed up with trial litigators to manage patent disputes.  He has managed and handled various aspects of patent infringement cases, including preliminary injunction, pleadings/motions, infringement and invalidity contentions, claim construction, fact and expert discovery, and trial preparation.

Charles also has significant cross-border dispute resolution experience, particularly in China.  Charles uses his understanding of China’s patent law, court system, and trial procedures to help his clients navigate pitfalls faced by many U.S. litigants, including cultural and language barriers, limited discovery, and potential bias.  In a representative matter, Charles worked with local counsel to successfully defend a U.S.-based Fortune 500 client sued in China for patent infringement with a damage claim of over $200 million Renminbi.

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.
