The Xerox Disclosure Journal [XDJ] is a publication by Xerox Corporation
which, for patent and intellectual property purposes, is defensive in
nature. In most industrial foreign countries, a publication of an
invention anywhere in the world serves to bar any person from filing an
application on that same invention after such publication. 

In the United States, this statutory bar to filing for a patent does not
become absolute until a year after such publication. That is, a person may
file within one year in the U.S. from the date of any such publication,
but must prove that the invention was made prior to the date of the
publication. 

Accordingly, Xerox, like several other large R&D corporations, publishes
on the subject matter of inventions which it might use in the future but
for which patent protection is not warranted. In this way, it preserves
its right to use the invention against any third parties who may later
come up with the invention and try to patent it. The journal, referred to
simply as XDJ, serves in this way as a defensive publication. It is
printed in-house and distributed around the world to libraries and patent
offices.

The XDJ is published bi-monthly and is in its twenty-second year of
publication. The last issue of each year contains an index both by U.S.
Classification and by author name placed at the end to complete the volume
set. A new issue of the XDJ is published on the second week of February,
April, June, August, October, and December, i. e. a bi-monthly schedule.
