American Inventors Protection Act of 1999 [AIPA] Law and Legal Definition

The American Inventors Protection Act (AIPA) is a United States federal law enacted on November 29, 1999 as Public Law. Title IV of the Omnibus Act is entitled the American Inventors Protection Act of 1999 and includes provisions to amend the Patent Law and reorganize the Patent and Trademark Office. The statute contains provisions to:

(1) curb deceptive practices by invention-promotion companies;

(2) reduce patent fees;

(3) provide a defense against infringement for a party who in good faith reduced a patented invention to practice at least one year before a patent's effective filing date;

(4) extend the patent term when the PTO is responsible for a delay in issuance; and

(5) require publication of a patent application 18 months after its filing unless the applicant requests otherwise.

The AIPA fundamentally changed many aspects of the patent application process in the United States. Accordingly, the U.S. Patent and Trademark Office (PTO) have issued many new rules to implement these statutory changes.

AIPA was amended later by the Intellectual Property and High Technology Technical Amendments Act of 2002.
