Our History

Johnson & Phung, LLC originated with John Stryker, Sr. who was one of the first patent attorneys in St. Paul dating back to the early 1900s. His son, John Stryker, after receiving an engineering degree from Yale University and a law degree from the St. Paul College of Law­­–a forerunner of William Mitchell College of Law–joined his father, and the firm name became Stryker and Stryker.

After Marvin Jacobson and Carl Johnson joined the firm it became Jacobson & Johnson LLC, and in 2000 Thomas Phung joined the firm.

Johnson & Phung, LLC was formed in 2017 when the esteemed Marvin Jacobson retired from Jacobson & Johnson, LLC.
