Ms. Peterson, of counsel in the firm's Minneapolis office, is a seasoned civil litigator with more than 15 years’ experience in patent litigation and other complex litigation matters, including cases in antitrust, trade secret, fraud, false advertising, and unfair competition. Ms. Peterson brings energy, practicality and a great sense of dedication to her work; she advocates passionately for her clients and happily becomes an integrated part of the client’s legal team. Before joining Kutak Rock, Ms. Peterson was a partner with an AmLaw 100 firm.

Ms. Peterson has represented her clients in various federal and state district courts around the country, the Federal Circuit Court of Appeals, the U.S. Supreme Court, the Federal Trade Commission, and the International Trade Commission. She spent 10 years of her career representing Union Oil Company of California and Unocal Corp. in high-stakes patent and antitrust litigation against the “Big Six” U.S. oil companies and the Federal Trade Commission. Other representative work includes:

  • Trial counsel representing Arctic Cat in Arctic Cat v. Bombardier Recreational Products and BRP U.S. Inc. (S.D. Florida). Following a three-week trial in Miami, a jury found that BRP willfully infringed two Arctic Cat patents related to controlled-thrust steering technology for personal watercraft (PWC). The Court trebled damages based upon BRP’s willful infringement, resulting in damages in excess of $48 million awarded to Arctic Cat.
  • Representing a medical device company as both plaintiff and defendant on patent infringement and trade secret claims related to embolic protection filters; driving a settlement of all claims.
  • Representing a robotics company as plaintiff and defendant in separate patent infringement matters with its competitor, resulting in the settlement of all claims.
  • Obtaining summary judgment for a Fortune 500 computer technologies company in defense of a patent infringement matter related to computer graphics.
  • Defending a Fortune 500 retailer in a class action (post-certification) for false advertising and deceptive trade practices.
  • Representing a patent holder in a patent infringement case related to silicone hydrogel contact lenses.
  • Representing the plaintiff in a fraud action arising from the purchase of residential mortgage-backed securities.
  • Obtaining a reversal of default judgment for a computer systems company on appeal to the Federal Circuit; driving the settlement of all claims.

Ms. Peterson has experience with standards-setting issues and has achieved dismissal of a unique “interfering patents” claim without discovery. Through a sabbatical from litigation in recent years, Ms. Peterson also acquired experience in independent film production and entertainment law.

Throughout her years in practice, Ms. Peterson has maintained a commitment to serve the community through pro bono work and on the boards of non-profit organizations – particularly in the area of child protection. She has represented adoptive parents, guardians ad litem, and children in contested adoptions and matters of abuse/neglect; she has served in various capacities for the Children’s Law Center of Minnesota including Board member (2009-2014), Vice President (2013), Development Committee Chair (2011-2013), and Volunteer Attorney (1998-present).
