Kolisch Hartwell, P.C. has 65 years’ experience dedicated to obtaining and protecting intellectual property rights for our clients. We have been primarily located for much of that time in the historic Pacific Building in vibrant downtown Portland, a fitting locale for a forward-thinking attorney group with a respected history.

Pierre Kolisch (1919-2008) founded our firm in 1952 and was joined by his first partner, Tim Hartwell, three years later. From its earliest years, the firm handled both prosecution and litigation matters. During his years at our firm, Pierre Kolisch twice argued cases before the U.S. Supreme Court: Brunette Machine Works, Ltd. v. Kockum Industries Inc., 406 U.S. 706 (1972), and Sakraida v. Pro, Inc., 425 U.S. 273 (1976).

A dynamic mix of intellectual property law

Kolisch Hartwell has continued to grow over the years, establishing a presence in Palo Alto, California and adding distinguished new partners skilled in intellectual property law with a focus on technology and science. The firm’s deeply experienced attorney team has successfully represented U.S. and international clients in a broad array of IP matters. Our partner John McCormack, who remains with the firm today in an of counsel position, argued a seminal trademark case before the U.S. Supreme Court: Park ‘n Fly v. Dollar Park & Fly, 469 U.S. 189 (1985).

Today, we retain the name Kolisch Hartwell to honor our founders.  We continue the tradition of developing new areas of expertise as IP law, technology, and science evolve through time.  We practice a dynamic mix of intellectual property law, including domestic and foreign patenttrademark, and copyright acquisition and clearance, as well as regional and national IP litigation and licensing.
