Betty R. Yu, M.S. is a Registered Patent Agent before the U.S. Patent & Trademark Office. She provides services to clients from interviewing inventors, drafting and filing applications, responding to office actions and obtaining allowances. Ms. Yu concentrates on inventions related to a broad range of technologies, such as:

  • Protein chemistry (enzymatic bioassay, purification and characterization, sequence analysis, column chromatography and gel electrophoresis)
  • Molecular biology (immunotoxin conjugation, gene expression related to tumor growth)

  • Structure-based drug design (protease inhibition based on X-ray crystallography, drug resistance mutations)
  • Bioinformatics (relational database design, high throughput screening, and assay development)


With training in biochemistry and pharmaceutical biotechnology, Ms. Yu has conducted scientific research in the development of antiviral therapeutics, first at the National Cancer Institute, and then at two start-up pharmaceutical companies in Maryland. She has extensive experience in various aspects of drug discovery and preclinical development, from structure-based drug design, to protein chemistry, enzymatic evaluation, X-ray crystallographic studies, high-throughput screening, bioinformatics, drug metabolism and pharmacokinetics (DMPK).

Ms. Yu’s professional dedication has resulted in 19 scientific journal publications and 41 abstracts for national and international conferences. Moreover, she has contributed to the filing of two investigational new drug (IND) candidates with the Food and Drug Administration (FDA). Ms. Yu also has successfully helped the European astronauts in growing protein crystal for the European Space Program in 2004. She is a co-inventor of U.S. Patent No. 7,320,878, which is directed to a method of therapeutic drug monitoring (TDM) in AIDS patients.

Ms. Yu served as Special Volunteer at the Office of Technology Transfer and Development of the National Institute of Diabetes & Digestive & Kidney Diseases (NIDDK), the National Institutes of Health (NIH) during 2009-2011. As a result, she gained special insights in analyzing and managing IP portfolios, as well as coordinating patenting, licensing, and direct marketing activities of the NIH inventions to accelerate technology transfer.

Ms. Yu participates in community outreach activities that are related to women, healthcare and education. Native to China, she enjoys and appreciates cross-cultural experiences bridging together East and West.
