Yonglin Liu, Patent Agent

Biography

Yonglin Liu has a broad technical background that includes degrees in Organic Chemistry and Physical Chemistry. After he received his Ph.D., Yonglin worked at the National Institute of Standards and Technology ("NIST") and the National Institute of Health ("NIH") with a National Academy, National Research Council ("NRC") Research Associate fellowship from 2006-2009, and as a guest research chemist from 2009-2011. He was involved in projects over a broad range of technologies, including: Materials Science and Engineering, Nanotechnology/Nanomaterials, Nanotoxicity, Organic Chemistry, Inorganic Chemistry, Biophysics, Life Science, Biofuels, Energy (battery, capacitors, etc.), etc.

From 2011-2012, he worked as a patent analyst at a D.C. search firm and as a patent agent at a D.C. law firm. Yonglin has extensive experience and expertise on patent search and analysis in the fields of Mechanical Engineering and Electrical Engineering, in addition to the above technical fields. As a registered patent agent, he has drafted US/PCT patent applications in the fields of Chemistry, Materials Science and Engineering, Life Science, Biofuels (biomass, bioethanol, Cellulosic ethanol, cellulases, hemicellulases xylanase, and mannanase, chemical pretreatments, enzyme cocktails, biomass hydrolysis, production process, etc.), Semiconductor (devices, packaging, processing, etc.) and Electrical Engineering. 

His experience includes: 

  • Preparing and prosecuting U.S. and international patent applications; drafting new patent applications (Chemistry, Materials Science and Engineering, Life Science, Biofuels, Semiconductor arts, Electrical Engineering arts, etc.); preparing substantive documents related to prosecution, and contributing to prosecution strategy.
  • Preparing and prosecuting U.S. and international patent applications in the field of biofuels including biomass, bioethanol, Biogas, Cellulosic ethanol, cellulases, hemicellulases xylanase, and mannanase, chemical pretreatments, enzyme cocktails, biomass hydrolysis, enzyme catalysis, production process, etc.
  • Providing technical and legal patent-related research and analysis; and conducting literature surveys with various databases. 
  • Strategically performing patent and scientific literature searches and analysis relating to patentability (novelty), validity, freedom-to-operate and infringement. 
  • Communicating effectively with customers in determining the scope of searches and drafting informative reports that clarify and summarize search results.
  • Providing technical support for patent interference and litigation proceedings; assisting attorneys with the required technical fields in preparation of legal opinions. 
  • Conducting long-term patent landscape studies to identify trends in a technology field, delivering competitive intelligence and identifying potential research and licensing opportunities.
