Patent Examiner Technical Training Program (PETTP) &
Site Experience Education (SEE) Program

The USPTO is seeking public assistance in providing technical training to patent examiners within all technology centers.  The Patent Examiner Technical Training Program (PETTP) is intended to provide scientists and experts as lecturers to patent examiners in order to update them on technical developments, the state of the art, emerging trends, maturing technologies, and recent innovations in their fields. Such guest lecturers must have relevant technical knowledge, as well as familiarity with prior art and industry practices/standards in areas of technologies where such lectures would be beneficial. With the opening of the Elijah J. McCoy satellite office in Detroit, guest lecturers now have the option of presenting a lecture in either Detroit, Michigan, or Alexandria, Virginia. Training delivered at both the locations will be broadcast to patent examiners across the entire USPTO as appropriate.

The Site Experience Education (SEE) Program provides patent examiners the opportunity to visit real-world sites, such as universities or industries, to learn about new technology and experience how technologies operate in the field. Examiners receive direct hands-on training specific to the technology area they work in. This program seeks to put experts such as innovators, scientists, and engineers together with the examiners at the sites where innovation is happening.

Neither the PETTP nor the SEE Program is intended as an opportunity for applicants to discuss pending applications with USPTO employees or to circumvent normal communication between applicants or applicants' representatives and USPTO employees. In addition, PETTP and SEE participants are not to provide advice or recommendations to the USPTO. The PETTP and SEE Programs are envisioned only as an opportunity to provide patent examiners with necessary training from scientists and experts working directly in the various technologies throughout the USPTO.
