I got some feedback from the inventor. I have appended Gary’s
initial
message to me followed by his elaboration when I asked if it
would be
OK to forward his private message to the list.

Hi David,

I think my patent examiner concurs with your suspicion there.

Best Regards,

Gary

Hi Gary,

As far as I can tell, you are not subscribed to the MC4D list; so
I presume that Eduard (or someone else on the list who does know
you) forwarded my post to you.

Would you mind if I forwarded your response to me to the list?
(Nice to have resolution.)

BTW - Do you have program that simulates it? (I could not find
one for the puzzle-equivalent cubically shaped version either.)

Regards,
David V.

Hi David,

No prblem, I am a Yahoo user myself and was browsing so I
responded through
that route. Please post by all means.

I guess I am just being honest as i now understand the UK patent
office’s
position is that the simulations aren’t patentable. I think that
there are
protections available under design rights and copyright
agreements but
unless my ideas were used offensively or obviously plagarised I
would not
see any reasons for being upset about it..

I would love to see a simulation app get out there, I have five
puzzles off
the patent (6 & 10 axis variations) and probably more in my head
and all are
CAD modelled (IGES). The 4D Cube one that you are interested in I
first saw
on wikipedia and its fascinating. At some point I intend to get
my head
around that and do (Or attempt? - as this looks very difficult))
a 4D
anologue of mine. Moreover, I’ll support independent efforts in
this.

To close, thanks again to you and Eduard for your interest in our
design, I
am genuinely grateful for this kind of feedback.

Best regards,

Gary

— In 4D_Cubing@yahoogroups.com, "David Vanderschel" <DvdS@…>
had earlier written:

I notice in the UK patent application for this puzzle
that the inventor is apparently trying to claim
coverage for an electronic simulation. I have my
doubts about whether that can hold up - since, at the
abstract level, we are just talking about tiles on the
surface of a sphere and permutations of them. (I
grant that there may be patentable matter at the
physical embodiment level for achieving a practical
implementation; but the figures depicting its
construction, which I looked at only briefly, were
hardly surprising.) However, all I can find is the
patent application, so I don’t know if the inventor
prevailed on the simulation aspect. Does anyone have
any insight on this issue?

Regards,
David V.

Dioctipoid is a very pleasent rotational mechanical
puzzle equivalent to a face turning
octahedron. Dioctipoid is written on the edge
elements as an ambigramm so the edge elements are
not oriented. The ambigramm is not necessary because
these elements cannot return home with the wrong
orientation. By coloring the face turning octahedron
normally we have oriented corners, oriented edges
and monocolored sides which are hence partially
anonymous and not oriented. I propose to add to
colored point in the corner of the triangular
sticker of each side element which is the same as
the color of the neighbouring side element on the
other octahedron side. So the side elements become
unique and oriented.

The facesides in the 4D FT 24cell are also not
unique and not oriented.
