About vILT

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.

See the full course schedule below for topics, dates, places, times, intended audience, and CLE credit.

Courses provided are free to attend.  In addition, CLE credit may be available for a vILT course in which you participate. However, CLE accreditation will generally only be applied for in the state from which the course is delivered.  Please review the available course schedule and descriptions below for additional information.

vILT is administered by the Office of Patent Training (OPT).

How do I participate in the vILT program?

Operating Procedures for Interested vILT Participants

Entry into the vILT program is granted based on available resources, training slots available, and appropriateness of the topics suggested. For granted requests, audience size will vary.

Weather-Related Emergencies and Unexpected Closings:

In the event of a weather-related emergency or other unexpected closing, vILT follows the operating status of the USPTO Headquarters in Alexandria, VA (normal operating hours are 8:30 am to 5:00 pm ET), as determined by Office of Personnel Management guidance.  As a result, vILT training for a particular day may have a delayed start or be cancelled due to inclement weather.  The USPTO is not responsible for any cost associated with a weather-related or other cancellation or delay.  Furthermore, no makeup session will be scheduled. 

Office Closed
vILT courses will be cancelled if USPTO Headquarters is closed.

Office Open with Delayed Arrival
vILT courses will be cancelled if the delay at USPTO Headquarters extends beyond the scheduled start time (e.g., if there is a 3-hour delay, a course scheduled to start at 11:00 am ET will be cancelled).  Otherwise, vILT courses will run at the scheduled time.

Early Dismissal
vILT courses will be cancelled if the early dismissal occurs during the scheduled course time (e.g., if there is a 3-hour early dismissal, a course running at 2:00 pm ET will be cancelled).

All other operating statuses (e.g., open with option for unscheduled leave or unscheduled telework)
vILT courses will run as scheduled.

For information on the current operating status of the USPTO Headquarters in Alexandria, VA, visit the OPM current status web page or call 202-606-1900.
