I know of three patents relevant to Phantograms. My comments
on them are those of a laymen
and you should take them in that way. If you need a real legal opinion on what they cover or
how they relate to each other, you should consult a patent lawyer. If you know of any other
patents relevant to Phantograms, please let me know.

"Process and Method of
Effective Angular Levitation of Printed Images and the Resulting Product"
Patent Number: 1,592,034
Filed: Sept. 6,1924
Issued: July 13, 1926
This patent describes a method of making an anaglyph image
appear at an angle to the
surface it is printed on. The technique described involves rotating the two stereo images
about a common point. At first glance this seems like a good way to produce major vertical
alignment problems in an image that would not be viewable.
The claims in the patent do not describe this technique but claim "... images of an object
in such angular relationship to each other as to neutralize the angle of inclination of the
inclined stereogram and to display the image in a substantially vertical position......". Sounds
like a Phantogram to me.
My first impression was that this was not a very well thought out idea. But Macy has several
other patents that show a deep understanding of stereo so I spent some serious time thinking
about it and realized he did know what he was talking about. I have made viewable images
using this technique. They have problems not present in other forms of Phantogram but are

Patent Number: 6,389,236
Filed: Feb. 1, 2000
Issued: May 14, 2002
This patent is specific to anaglyph Phantograms. It does not
address any other method of
displaying an image. The description of how to make a Phantogram seems a little vague
to me and the patent claims do not specify photographic images but seem to claim all
Phantograms including hand drawn ones. I find the claims very difficult to follow.
"Process for Making
Stereoscopic Images Which Are Congruent With Viewer Space"
Patent Number: 6,614,427
Filed: Feb. 1, 2000 "claims from a Feb 1,1999 filing"
Issued: Sep 2,2003
This is a very well written patent. It references previous use
of Phantogram illustrations in
drawings. It covers virtual all forms of stereo image presentation and specifically refers to
images created by digital manipulation. Images created optically do not appear to be covered.
The drawings and explanation of how to make Phantograms are clear enough to enable
a careful reader to figure out how to make them. The language is a little had to follow, like
most patents, but it can be understood and is well worth studying.
Note: The method of making Phantograms I show in the presentation on this site is probably
covered by this patent.
