Helen Baca focuses on IP portfolio management, strategic client counseling, and patent prosecution in diverse scientific and engineering fields. She has experience in performing portfolio audits, preparing and prosecuting patent applications, and advising on patent infringement, freedom-to-operate, validity, and inventorship issues. Areas of expertise include advanced chemical and biological materials, small molecule and protein therapeutics, nucleic acid and peptide technology, drug formulations, drug delivery systems, drug discovery platforms, microfluidics, droplet-based systems, medical devices, memristors, photonic systems, and microresonators.

Dr. Baca received her J.D. from the University of Pittsburgh, School of Law, and her Ph.D. from the University of Chicago in the Department of Chemistry. Her graduate research was interdisciplinary and led to the development of a droplet-based microfluidic platform for performing biological and chemical reactions.

Prior to joining WAVS IP, Dr. Baca was Senior Intellectual Property/Patent Counsel at Sandia National Laboratories and an Associate at Clark & Elbing, LLP.
