According to the Lanham Act, trademarks and service marks include any word, name, symbol, or device used to identify and distinguish the goods and services from the goods and services of others, and to indicate the source of the goods and services. Thomas Jefferson University's name and logotype, the various "Jeff" marks, and all the university's other names, slogans, designs, and indicia of origin, all function as trademarks and service marks.
The Intellectual Property Division deals not only with trademarks and service marks, but also with trade secrets, utility models, industrial designs, and copyrights as well. All of these are most important for technological development and economic growth of the university.
"[An owner's] mark is his authentic seal; by it he vouches for the goods which bear it; it carries his name for good or ill. If another uses it, he borrows the owner's reputation, whose quality no longer lies within his own control. This is an injury, even though the borrower does not tarnish it, or divert any sales by its use; for a reputation, like a face, is a symbol of its possessor and creator, and another can use it only as a mask."
