August 1970: By 1970, Patent Resources Group establishes itself as the industry leader in Patent Exam preparation. For years students had reported significantly better results on the U.S. Patent Office Exam. The program’s success was, in part, due to its focus on details of effective practice that continues to this day. As indicated at the time, "this is much more than a Bar Review Course. It instructs in the details and mechanics of the craftsmanship of patent prosecution – it teaches the common denominators of effective practice … this is a valuable training experience. Many patent attorneys and agents take the course for refresher training long after having been admitted to practice."
August 1973: PRG students achieve the highest pass rates on the Patent Exam. This tradition continues to the current day.
August 1974: The accolades roll in! With the incredible success of the Patent Bar Review Course, PRG begins to publish accolades from many pleased students and practitioners. The course is now recommended for individuals with no patent background.
August 1975: PRG becomes the first patent law educator to monitor the frequency of questions that appear on the Patent Exam. The company prints the results in the announcement of the August 1975 Annual Summer Institute. This information directs PRG students to focus on the areas most likely to appear on the Patent Exam.
November 1975: Part IV of 35 USC is added to accommodate the Patent Cooperation Treaty, which had been signed in 1968.

is published. At the time, the title of the treatise was Patent Preparation &
Prosecution Practice. Its publication "changed the face and foundation of education in patent law."

The course also delivered a workshop on how to prosecute EPC with and without PCT.
October 1978: PRG adds a new series of seminars across the country that supplements its leading Spring and Summer Programs. The programs feature patent prosecution for a winning trial strategy and the basics of patent licensing. The two-day seminars are taught by Irving Kayton and J. Thomas McCarthy.

Patent Practice and included in the now legendary Patent Bar Review Course at PRG. The Patent Exam preparation course becomes the "only systematic, self-contained
training program for license to practice patent law that there has ever been since the first patent statute was enacted in 1790."
