DENNISON ASSOCIATES traces its heritage back to the turn of the century, making
it one of the oldest patent firms in Canada. It all began in 1904 when Herbert
J. S. Dennison began practicing as a patent attorney. Mr. Dennison was one of
the founding members of the Patent and Trade-mark Institute of Canada (now
known as the Intellectual Property Institute of Canada), the premier
professional organization in Canada in the intellectual property field. He was
its third president in 1928/29. Mr. Dennison was joined by Douglas S. Johnson
in 1946. When Mr. Dennison passed away in 1948, his practice was continued by
Mr. Johnson and it continues today as DENNISON ASSOCIATES.
MacBeth & Johnson
MACBETH & JOHNSON was established in 1954 by Douglas S. Johnson and the
late John MacBeth. In 1974, John left practice to pursue a full-time career in
politics. The firm continued under Doug's direction, focused exclusively on
intellectual property law representing a large number of leading companies in a
variety of industry groups.
