Pasquale ("Pat") Joseph Federico (March 25, 1902 – January 2, 1982) was a lifelong mathematician and longtime high-ranking official of the United States Patent Office. Biography He was born in Monessen, Pennsylvania. About 1910 the family moved to Cleveland, Ohio where he gained a bachelor's degree in physics at Case Institute of Technology in 1923. He then received his LL.B or law degree from Washington College of Law in 1932. Federico entered the Patent Office in 1923 as a junior examiner in Division 43, and by 1935, he became the Assistant Chief of his division and then became the Division Chief in 1940. He was appointed to the Board of Appeals in 1947, became the Examiner-in-Chief there, and remained there until his retirement from the Office in 1977. Federico was also a prolific author of articles dealing with intellectual property and was also instrumental in several major changes to how patents were issued and how intellectual property is treated, assisting Congress in preparing the Patent Act of 1952 along with co-author Judge Giles Sutherland Rich, in the 1940s to 1950s - in fact, according to Judge Rich, Federico was the man most responsible for getting the 1952 Patent Act through Congress and enacted into law. Federico also served for many years as the Patent Office's unofficial historian and Editor in Chief of the Journal of the Patent and Trademark Office Society (JPTOS) from 1936 to 1942. Some of his most well-known contributions to the field of mathematics focused on the study of perfect squares and the writings of Descartes. Federico is credited for providing the quotation said to underlie the scope of patentable subject matter under United States law when he testified before a House subcommittee in 1951 that "under section 101 a person may have invented a machine or manufacture, which may include anything under the sun that is made by man," so long as it satisfies the requirements of the patent statute. This testimony was later quoted by the United States Supreme Court when the Court held in 1980 that living organisms were proper subject matter for patents. Nevertheless, the Supreme Court has since ruled that US patent protection does not extend to "Laws of nature, natural phenomena, and abstract ideas." Judge Giles S. Rich of the Federal Circuit made these eulogistic remarks about Federico in a JPTOS article published shortly after Pat's death: Pat Federico was the
