Gordon Walford Daisley, 77, a Washington patent lawyer and former Navy Officer, died of cancer Friday at his home in Chevy Chase.

A senior member in the law firm of Cameron, Kerkam, Sutton, Stowell and Stowell, he had joined its forerunner, Cameron, Kerkam and Sutton in 1932.

A patent trial specialist, Mr. Daisley helped procure U.S. patents on the first frozen food packaging for Birdseye and the first tubeless tires for B.F. Goodrich. He specialized in later years in international patent law.

He was born in Brooklyn, N.Y. A graduate of the U.S. Naval Academy in 1923, he served as an officer until 1930, when he left the Navy to attend law school. He graduated at the head of his class from Georgetown University Law School in 1933. He was a member of the Order of the Coif and Phi Delta Phi legal fraternity.

Mr. Daisley rejoined the Navy the day after the attack on Pearl Harbor in 1941. He served throughout World War II in naval intelligence at the code-breaking station here. He received the Legion of Merit for his role in helping to break the Japanese code.

He was a member of the D.C. and American bar associations, past president of the D.C. Patent Lawyers Club and the Kenwood Citizens Association, and a member of Columbia Country Club.

He is survived by his wife, the former Augusta G. Prescott, of the home; two sons, Gordon W. Jr. and William P., both of Chevy Chase; a brother, Roger M., of Merced, Calif., and five grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the U.S. Navy Academy Athletic Association in Annapolis.
