The USPTO's Patent Examiner Technical Training Program (PETTP) is requesting voluntary assistance from technologists, scientists, engineers, and other experts from industry and academia to participate as guest lecturers and provide technical training and expertise to patent examiners regarding the state of the art.

Guest lecturers provide relevant, historic and current technical knowledge, including industry practices/standards in technological areas of interest. Guest lecturers must also have relevant technical knowledge and industry practices/standards in areas of technologies where such lectures would be beneficial.

Guest lecturers have the option of presenting a lecture in-person or virtually from their own location. In-person presentations can be made at our Alexandria, Virginia headquarters or at one of our regional offices in Dallas, TX, Denver, CO, Detroit, MI and San Jose, CA. Training delivered at each location will be broadcast to patent examiners across the entire USPTO.

PETTP is not 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 participants are not to provide advice or recommendations to the USPTO. The PETTP is 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.

Virtual Instructor Led Training (vILT) Program

Are you or your client interested in attending an online course of an examination topic?  Virtual Instructor Led Training (vILT) is designed to allow our stakeholders to be briefed on a variety of focused topics related to examination practice and procedure derived from recent training delivered to experienced USPTO examiners. The primary purpose of vILT is to provide a vehicle by which recently delivered examination training is shared with the external stakeholders. The interactive online format of vILT allows participants to remotely attend the training without the need to travel to USPTO locations.
