Warning! Patent Agent Privilege Ends Abruptly

Matthew M. Welch

Say I have lost all faith in patents, judges, and everything related to patents. –Thomas Edison

Thomas Edison and many of the innovators following in his footsteps have been disgruntled and discouraged by United States patent law. However, patentintensive industries promote innovation, increase the GDP, and create millions of jobs. Patent law is vital to the continued prominence of America as a world power, and, to continue that prominence, patent law must adapt to current times. As a start, it must begin providing solutions to a number of problems plaguing the patent realm. One of the most outstanding problems currently running course through patent law is the dynamic between the attorney-client privilege and patent agents. The problem is two-fold. First, some courts have extended the privilege to patent agents, but the way they are treating this privilege is insufficient. Second, other courts are not recognizing the privilege whatsoever.

Attorney-client privilege is a pillar of the legal system that is entrenched throughout the United States. This privilege was instituted to allow full and frank discussions between clients and their attorneys. The purpose behind this was to allow attorneys to fully represent their clients based on all available facts. However, attorneys are not the only players in the field of patent law. In fact, one fourth of all patent practitioners are non-attorneys. These individuals are patent agents. 


BRUCE A. LEHMAN 1993-1998

Bruce A. Lehman was born in Beloit, Wisconsin, on September 19, 1945. He received history and law degrees from the University of Wisconsin – Madison and served as legal counsel to the Wisconsin state legislature before entering military service during the Vietnam War. He was a first lieutenant in the U.S. Army.  

Afterward he worked at the Department of Justice in Washington, D.C. He joined the staff of the House Judiciary Committee when it was considering a recommendation to impeach President Richard Nixon. In 1978 he was appointed chief counsel of the Judiciary subcommittee with jurisdiction over intellectual property issues. He then spent 10 years in private law practice in Washington, where he was active in civic affairs.

President Bill Clinton appointed Lehman assistant secretary of commerce and commissioner of patents and trademarks, and he entered service on August 11, 1993. He was the first openly gay man to be confirmed by the U.S. Senate. 


PTAB Practice Tips on Oral Arguments

James A. Worth

PTAB oral arguments provide an opportunity for parties to highlight select points from their written briefs and to answer questions from the panel hearing the case. Failing to answer questions from the panel is one of the quickest ways to lose credibility with the panel. This article sets forth certain considerations and practice tips for counsel appearing for arguments before the PTAB.

In particular, this article suggests that counsel refrain from relying on evidence not already of record or new theories of a case, that counsel prepare for a wide range of questions based on the record, and with respect to AIA hearings, that counsel may wish to take a flexible approach towards the use of slide presentations and exhibits. This article will address each suggestion in turn, and review some of the animating considerations.

HARRY F. MANBECK JR. 1990-1992

Harry F. Manbeck Jr., was born in Honesdale, Pennsylvania on June 26, 1926. He received a bachelor’s degree in electrical engineering from Lehigh University and was hired as an engineer by General Electric Co. in 1949. A few years later he received a law degree from the University of Louisville and became a GE patent attorney.

He rose through the ranks at GE, a company with a large patent department, to become the chief patent counsel, a position he would hold for 20 years. During that period he was a prolific, well-known speaker on intellectual property rights.

President George H.W. Bush appointed Manbeck assistant secretary of commerce and commissioner of patents and trademarks, and he took the oath of office on March 12, 1990.



DONALD J. QUIGG 1985-1989

Donald J. Quigg was born April 28, 1916, in Kansas City, Missouri. He received a bachelor’s degree in business administration from the University of Oklahoma and a law degree from the University of Missouri. After a brief period with a law firm he entered the U.S. Army during World War II and received the Silver Star Medal for valor in combat.

In 1946 he joined Phillips Petroleum Co. in Bartlesville, Oklahoma, as a staff patent attorney and studied chemistry at night. In an era when employees often stayed with a company for an entire career, Quigg was a Phillips patent attorney for 35 years and was named an inventor in 10 Phillips patents.

He was chief patent counsel for his last 10 years at Phillips. Although Quigg worked at Phillips headquarters in Oklahoma, he was responsible for an office the company maintained in Washington, D.C., to train patent attorneys. The office monitored patent legislation and regulations for Phillips, giving Quigg familiarity with patent policy issues in Washington.

In 1981 he retired and took the post of deputy commissioner of patents and trademarks. After four years as deputy President Ronald Reagan appointed him assistant secretary of commerce and commissioner of patents and trademarks. He took office on October 13, 1985, at age 69. 



Gerald J. Mossinghoff was born in St. Louis on September 30, 1935. He received a bachelor’s degree in electrical engineering from St. Louis University and a law degree from George Washington University.

He worked four years as an examiner at the Patent Office, starting in 1957, before leaving to join a law firm. He returned to government service for a series of jobs including the post of director of legislative planning at the USPTO. Later, at the National Aeronautics and Space Administration, he rose to the position of deputy general counsel. 

President Ronald Reagan appointed Mossinghoff commissioner of patents and trademarks, and he took the oath of office on July 8, 1981. The next year Congress changed the title to Assistant Secretary of Commerce and Commissioner of Patents and Trademarks, and Mossinghoff reported directly to the secretary of commerce. 



Sidney A. Diamond was born October 17, 1914, in New York City. He received a bachelor’s degree from Dartmouth College and a law degree from Harvard University.

He practiced law in New York City and Washington, D.C. From 1943-46 he worked for the Justice Department as special attorney and special assistant to the attorney general. From 1971-78 he lived in Tucson, Arizona.

In the spring of 1978 President Jimmy Carter appointed Diamond assistant commissioner of trademarks, a post that at the time required presidential appointment with Senate confirmation. Later that year President Carter elevated him to commissioner of patents and trademarks. Diamond took the oath of office on November 29, 1979.
