Content Page Experience
  • Pentelovitch has tried hundreds of cases over the course of the past 33 years, spanning subject areas such as antitrust, securities, racketeering, fraud, contracts, employment discrimination, banking, and intellectual property.  During the past 20 years a majority of his cases have been concentrated in two areas, intellectual property disputes and disputes involving owners of closely-held business enterprises.  The intellectual property cases have related to disputes involving trade secrets, intellectual property licenses, confidentiality agreements, and noncompetition agreements. 
  • With respect to disputes involving the owners of closely-held businesses, Pentelovitch is recognized as one of the leading experts in the field in Minnesota.  In a seminal case more than 20 years ago, he won the first major shareholder oppression case under the revised Minnesota Business Corporation Act, recovering over $33 million for his clients;  more recently, in 2005 a court ordered that another Pentelovitch client be paid nearly $300 million as the result of shareholder oppression.
  • Since January 2005, Pentelovitch has led teams of Maslon lawyers which have tried seven complex cases to verdict or final decision, winning all of them.  In four of the cases Maslon represented the plaintiffs; in two of those cases, he obtained aggregate damages totaling more than $7 million, and in the other two he obtained injunctions.  In the other three cases Maslon represented defendants in intellectual property disputes in which plaintiffs collectively sought damages aggregating more than $400 million; Pentelovitch's clients were vindicated in all three cases and the plaintiffs recovered nothing.
