Ian Papendick is a Partner at Bartko Pavia LLP practicing in Boulder, CO with 18 years of antitrust and litigation experience as a government enforcer, in-house lawyer, law professor, and partner at another major global law firm. He combines rock-solid fundamentals with innovative strategic thinking to anticipate client challenges and develop creative solutions that drive business success. His practice spans the full spectrum of antitrust matters—from government investigations and merger counseling to complex commercial and class action litigation, compliance counseling, and emerging technology issues, including AI applications.

Ian's role as an antitrust enforcer positioned him at the forefront of high-stakes merger challenges and complex investigations. As an Assistant Attorney General for Colorado, he was a leader in the state's challenge to the $25 billion Kroger-Albertsons merger, directing a multi-expert team through a four-week bench trial. This groundbreaking state court trial showcases his ability to navigate sophisticated merger litigation at the highest levels.

From his in-house experience at Instacart and Bank of America, Ian has the perspective to deliver concise, actionable, business-focused advice that resonates with in-house teams and executives. With extensive experience in multinational investigations, Ian excels at guiding foreign clients through complex U.S. legal processes.

Ian's extensive litigation experience encompasses both plaintiff and defense representations across technology, retail, consumer packaged goods, healthcare, and life sciences sectors. He has successfully guided clients through multinational cartel investigations, MDL proceedings, and class action litigation involving billions of dollars in potential damages.  He maintains a significant focus on the intersection of antitrust and intellectual property law, including FRAND, standard-setting, and patent licensing disputes.
