Overview

Karan Jhurani has a multi-faceted practice at Fish & Richardson, focusing on patent prosecution and counseling, post-grant proceedings before the Patent Trial and Appeal Board, and complex patent litigation.

Karan's significant experience in all areas of patent law has equipped him to provide a full range of patent services to clients while developing and executing sound legal strategies that consider every aspect of intellectual property protection. Karan works with clients to define what a "win" looks like and then diligently and meticulously goes and gets those wins, whether that means obtaining patent protection at the U.S. Patent and Trademark Office for a critical invention, litigating in court to prevent competitors or third parties from encroaching upon clients' inventions, or leading a focused attack at the PTAB that is geared toward neutralizing and eliminating third-party patents that are asserted against clients.

Karan has significant experience in developing and managing patent portfolios, performing due diligence, and providing strategic IP counseling to a range of clients, from early-stage companies to industry leaders. Karan has been entrusted by several clients to manage all or a portion of their patent portfolios and to help develop strong patent assets that provide both offensive and defensive value to the client. Notably, Karan currently manages portfolios for clients innovating in the e-commerce, fintech, and sporting goods industries, and has a particular affinity for machine learning, encryption, and security-based technologies.

At the PTAB, Karan has successfully represented both patent owners and petitioners in post-grant proceedings. Karan has substantial experience in all major aspects of post-grant proceedings, from petition drafting to conducting depositions to arguing at oral hearings. Karan recently secured victories for a client in the digital analytics space that resulted in invalidation of all claims of multiple patents asserted by a competitor. Karan’s litigation practice focuses on representing clients in actions filed in U.S. District Courts across the country and at the U.S. International Trade Commission. In one notable matter, Karan was involved in a closely watched ITC patent infringement case — part of a massive, high-stakes global litigation — for client Carl Zeiss AG and its customer ASML Netherlands BV against Nikon. Karan was the key attorney on that case, responsible for two patents that ultimately resulted in a determination of infringement that excluded several Nikon digital cameras from the U.S.

Through his interdisciplinary practice, Karan has extensive experience with a wide range of products and technologies, including:

Technologies leveraging machine learning techniques (e.g., deployment of neural networks for sequential tasks, reinforcement learning)

Fintech-related technologies

Encryption and cryptography-based technologies

Digital image and video processing technology

Business intelligence and advanced analytics

Mobile applications and security

Sporting goods design (including development and deployment of impact mitigating materials and structures)

Manufacturing and industrial management systems

In addition to his IP practice, Karan devotes a significant amount of time to diversity issues, including in his former role as co-chair of the firm's Allyship Committee and the Diversity Advisory Committee. Karan also invests his time in pro bono matters. He is currently involved in a litigation matter on behalf of a father and son who are suing the federal government over claims associated with the prior U.S. administration's "separate at the border" policy.

When he is not working, Karan spends his time with his beautiful wife, Sunaina, and keeping up with his 5- and 3-year-old sons. And when the wife and boys allow it, Karan also enjoys working out at CrossFit and playing golf.
