Sofia Caroline Brooks

Sofia Caroline Brooks is an associate at Wilmer Cutler Pickering Hale and Dorr, where her practice centers on high-stakes, complex litigation and appellate matters. Her experience in patent litigation primarily involves defending technology companies. She has worked on significant cases across various technology areas, including network security, cybersecurity, and software, as evidenced by her involvement in major litigation concerning threat intelligence filtering and encrypted traffic analysis technologies.

Ms. Brooks has demonstrated a clear focus on the defense side of patent litigation, with her tracked appearances exclusively representing defendants. Notably, she was part of the WilmerHale team representing Cisco Systems, Inc. in the protracted Centripetal Networks, Inc. v. Cisco Systems, Inc. litigation.

In the Centripetal Networks case, a Virginia federal judge initially awarded Centripetal Networks a judgment of $2.6 billion to $3.2 billion against Cisco for willful patent infringement related to network security patents. However, Ms. Brooks was part of the WilmerHale appellate team that secured a significant victory for Cisco when the U.S. Court of Appeals for the Federal Circuit vacated this multi-billion dollar judgment. The Federal Circuit found that the district court judge had failed to recuse himself due to a conflict of interest involving his wife's stock holdings in Cisco, remanding the case for reassignment to a new judge. While inter partes reviews (IPRs) were part of the broader litigation strategy in Centripetal v. Cisco, with several asserted claims being held unpatentable in IPRs, Ms. Brooks' public profile does not indicate regular appearances in PTAB or IPR proceedings.

Ms. Brooks earned her J.D. from The University of Chicago Law School in 2018 with honors, and her B.A. in English from Harvard University in 2012, cum laude. She is admitted to practice in Massachusetts and before the U.S. District Court for the District of Massachusetts.
