Reference Collections of U.S. Patents and Trademarks
Available for Public Use in Patent and Trademark Depository Libraries
The following libraries, designated as Patent and Trademark Depository
Libraries (PTDLs), receive patent and trademark information in various
formats from the U.S. Patent and Trademark Office. Many PTDLs have on
file all full-text patents issued since 1790, trademarks published since
1872, and select collections of foreign patents. All PTDLs have both the
patent and trademark sections of the Official Gazette of the U.S. Patent
and Trademark Office. The full-text utility and design patents are
distributed numerically on 16 mm microfilm, and plant patents on color
microfiche. Patent and trademark search systems on CD-ROM
(Compact Disc-Read Only) format are available at all PTDLs to
increase utilization of and enhance access to the information found
in patents and trademarks. It is through the CD-ROM systems
that preliminary patent and trademark searches can be conducted
through the numerically arranged collections.
All information is available for use by the public free of charge.
In addition, each PTDL offers reference publications which outline
and provide access to the patent and trademark classification systems, as
well as other documents and publications which supplement the basic search
tools. PTDLs provide technical staff assistance in using all materials.
Facilities for making paper copies of patent and trademark information are
generally provided for a fee.
Since there are variations in the scope of patent and trademark
collections among the PTDLs, and their hours of service to the public
vary, anyone contemplating use of these collections at a particular
library is urged to contact that library in advance about its
collections, services, and hours in order to avert possible
inconvenience.
