Hojung Cho Ph.D.


Hojung Cho focuses her practice on patent prosecution, strategic counseling, and litigation primarily in the mechanical, chemical, and biotechnology areas. She has extensive experience in preparing new patent applications, prosecuting U.S. and foreign applications, and representing applicants in appeals and reexamination proceedings. Dr. Cho also counsels clients in managing patent portfolios; providing patentability, enforceability, and infringement opinions; and performing due diligence for intellectual property asset transactions. Her litigation experience includes fact discovery and development of noninfringement and invalidity positions in U.S. district court and U.S. International Trade Commission (ITC) Section 337 litigations.

Dr. Cho’s practice spans a wide range of technologies, including fuel cells, biofuels, metallurgical arts, catalyst technologies, diagnostic and detection systems, biomaterials, optical imaging, medical devices, and chemical processes and equipment. Dr. Cho works with clients ranging from early-stage companies to large multinational companies.

During her doctoral training, Dr. Cho acquired broad experience in optical imaging, molecular biology, biochemical assays, micro/nano technology for biological applications, and biomedical device developments. Dr. Cho's dissertation research focused on studying collective behavior of bacteria in controlled microenvironments using microfluidic devices. Its significance for investigating biofilm formation and infectious diseases was highlighted in numerous press reports including Nature, Nature Reviews Microbiology, and MSNBC. While earning her bachelor’s degree at Seoul National University, she conducted research on developing novel bacterial enzyme systems.
