Public Searching

Universal Public Workstations at the Byron G. Rogers USPTO Satellite Office in Denver provide access to the agency’s public electronic patent and trademark collections. The public search room is designed to enable individual researchers to conduct self-directed searches. The Denver office has four public workstations available that have the same access requirements and print capabilities as identical public workstations in USPTO’s Public Search Facility. Customers who have limited experience in patent or trademark searching, or are new to the subject area of patents and trademarks, are strongly encouraged to first contact or pay a visit to the Denver Public Library. The Denver Public Library is a Patent and Trademark Resource Center (PTRC) that offers beginner orientation on searching for patents and trademarks and is located about one mile from the Denver office at 10 West 14th Avenue, Denver, CO 80204.

Public searching on universal public workstations is available from 9 AM - 4 PM MT Monday - Friday, except federal holidays.

Please work with your examiner to schedule an interview at the Denver Satellite Office using video conferencing equipment.

Collaborative Spaces

The USPTO partnered with GSA for a Workplace Engagement plan study how satellite office spaces might be aligned to meet agency goals, and to better provide spaces for enhanced collaboration and public outreach.  As a result, the Denver USPTO office has a number of collaborative spaces within the USPTO space for public to use.  For example, the Collaboration Center is designed to enable Rocky Mountain region educators, inventors, entrepreneurs, and IP community to collaborate while allowing USPTO to provide them with appropriate information and resources.   This space may be configured in different ways to conduct conferences equipped with a whiteboard wall, whiteboard easels, and two telephones.  The spaces do need to be reserved in advance.

Patent Trial and Appeal Board

Judges for the Patent Trial and Appeal Board (PTAB) in Denver work in conjunction with judges at the USPTO’s main campus in Alexandria, VA.  Also, the Denver Hearing Room is equipped with enhanced collaboration equipment that provides a new venue to our stakeholders from which to participate in Board proceedings.
