Parvathi Kota, Ph.D.


arvathi Kota is a registered patent attorney and focuses her practice on patent litigation, inter partes review, and intellectual property transactions, with experience in preparation and prosecution of U.S. and foreign patent applications, opinion work, due diligence, and reexamination.

Parvathi has fifteen years of research experience in biochemistry, molecular biology, and plant biotechnology. She worked as a research scientist in the laboratory of Nobel Laureate Professor Har Gobind Khorana at Massachusetts Institute of Technology, where she studied structure-function relationships in rhodopsin. Her postdoctoral work focused on the genetic modification of lignin biosynthesis, and she identified new substrates for key enzymes in the lignin biosynthesis and proposed a new pathway for alfalfa. Parvathi’s doctoral dissertation focused on the purification and regulation of photosynthetic enzymes.

Parvathi has published several articles in peer-reviewed science journals, and has been invited to present her research at several national and international scientific meetings. She also served as a reviewer for the U.S. Department of Agriculture grant applications and for scientific journals. While at MIT, she taught an advanced undergraduate seminar course on G-protein coupled receptors.

Prior to joining Skiermont Derby LLP, Parvathi was an associate at Paul Hastings LLP in New York. She previously worked as a technical advisor/patent agent at Paul Hastings in New York and as a technical specialist/patent agent at Finnegan, Henderson, Farabow, Garrett & Dunner, LLP in Washington, D.C. and Cambridge.
