Suspension of person to person appointments.

Our library is open.  I can schedule a personal session.  We have a room that can be used while keeping social distancing. Please use the "Schedule Appointment" link in my profile on the right. I can also meet with you virtually via a WebEx session.  You will be asked to download a small app in order to use WebEx.  The university has a subscription to WebEx and it is a secure encrypted session. I will be alternatively working from home and from my office. My chat hours will vary. I also recommend contacting the United States Patent and Trademark Office Inventor Assistance Center at  1-800-786-9199, or the Trademark Assistance Center via email at

Access to PubWEST and PubEAST will be by appointment only.  

If you have any questions please email me at

Thank you,
