Indranil Sarkar, Ph.D., focuses his practice on client counseling and strategic patent prosecution in the area of electrical and computer engineering.

Indranil manages patent portfolios of clients ranging from individual inventors to Fortune 50 companies, analyzing innovative technologies, identifying scopes of inventions, reviewing related patent landscapes to formulate protection strategies, and drafting and prosecuting patent applications.

He handles several large multi-national portfolios, and is experienced in formulating unified prosecution strategies across the globe, including expediting prosecution in relevant jurisdictions via the PPH, ASPEC, etc. He also advises clients on effective commercialization/enforcement of intellectual property, including conducting freedom to operate studies to assess competitors’ IP portfolios, and formulating strategies to avoid potentially adverse situations. He also has significant experience in post-grant practice, particularly in drafting and prosecuting reissue applications.

Indranil's technical focus is in the areas of wireless technologies, signal and image processing, blockchain, video coding, computer architecture, biometrics, medical devices and software. He has extensive experience in drafting and prosecuting standard-essential patents, particularly ones related to the H.264 and MPEG-4 video coding standards and the 5G wireless standard.

Prior to his legal career, Indranil was a researcher in the area of signal/image processing. His doctoral research was in the area of pulse compression codes and their mismatched filtering for various radar, communications, medical, and image processing applications. He has served as a reviewer for several international journals, including IEEE Transactions on Aerospace and Electronic Systems, Elsevier Signal Processing, and Elsevier Digital Signal Processing. He continues to serve as a reviewer of Ph.D. dissertations for students at his alma mater, Visvesvaraya Technological University.
