Papool Subhash Chaudhari

Papool Subhash Chaudhari is a patent litigation attorney with a practice focused on intellectual property disputes, particularly involving software, communications, and media content technologies. His experience includes matters related to "podcasting patents" and systems for disseminating serialized media. Chaudhari is associated with Chaudhari Law, PLLC, and has also been associated with Pra Law. He was admitted to the State Bar of California on January 9, 2006, and his license is currently inactive.

Chaudhari has experience representing patent owners, including patent assertion entities (PAEs), in both offensive and defensive postures. His case history shows him working both plaintiff and defendant sides, specifically representing Personal Audio LLC in significant patent litigation. As plaintiff's counsel for Personal Audio LLC, he was involved in Personal Audio LLC v. CBS Corp.. Although a jury initially awarded Personal Audio $1.3 million, the asserted patent claims were later invalidated through an inter partes review (IPR) proceeding, leading to the vacating of the jury verdict and a judgment in favor of CBS.

Chaudhari also defended Personal Audio LLC's patent in the IPR context in Electronic Frontier Foundation v. Personal Audio LLC. In this notable case, the Electronic Frontier Foundation (EFF) successfully challenged the validity of Personal Audio's "podcasting patent" (U.S. Patent No. 8,112,504) before the Patent Trial and Appeal Board (PTAB). Chaudhari served as counsel for Personal Audio LLC during the appeal of the PTAB's decision to the Federal Circuit, where the invalidation of the patent claims was affirmed. The U.S. Supreme Court subsequently denied Personal Audio's petition for review, making the PTAB's invalidation ruling final. This demonstrates his experience with PTAB proceedings and subsequent appeals to the Federal Circuit.
