Karen Jacobs

Karen Jacobs is a partner in the Intellectual Property Litigation group at Morris, Nichols, Arsht & Tunnell LLP with a practice focused on patent litigation in the U.S. District Court for the District of Delaware. Her experience covers a broad range of technologies, including pharmaceuticals, life sciences, biotechnology, computer software, electronics, and telecommunications. Her firm biography notes extensive work for branded pharmaceutical companies in ANDA and biosimilar disputes.

Based on tracked appearances, Jacobs has exclusively represented defendants. This defense-side focus is further supported by her representation of companies like Symantec against infringement claims from non-practicing entities such as Intellectual Ventures. She has spent her entire career at Morris, Nichols, Arsht & Tunnell, a firm recognized for its leading patent litigation practice in Delaware.

In one of her most notable tracked cases, Intellectual Ventures I LLC v. Symantec Corp., Jacobs served as local counsel for defendant Symantec. The case involved patents related to anti-malware and anti-spam software. The litigation resulted in a significant victory for the defense, with the district court finding the asserted patents invalid as ineligible under 35 U.S.C. § 101, a judgment that was affirmed by the Court of Appeals for the Federal Circuit. She also represented Yahoo! Inc. as local counsel in Gigex, Inc. v. Yahoo! Inc. While public information on her experience in post-grant proceedings is not readily available, her primary focus appears to be on district court litigation.

Jacobs earned her J.D., cum laude, from Harvard Law School and her B.A., summa cum laude, from the University of Pennsylvania.
