From burgeoning high-tech companies to large international manufacturers, clients regularly turn to Greene Espel to represent them in major disputes involving trade secrets, patents, trademarks, and copyrights.

We take pride in working with in-house and outside experts to master complicated technical subjects and in presenting those concepts to judges and juries in an understandable way.  Our lawyers have litigated, tried, and handled on appeal IP cases in Minnesota and across the United States, often with tens or hundreds of millions of dollars at risk.

We have deep experience handling IP disputes in district courts and circuit courts of appeal around the country, the International Trade Commission, and the Patent Trial and Appeal Board.
