So producing a rotating prism without licence is an infringement, but producing a rotating pyramid is not

Yes, that's the way I would read it. If there is a nonrectangular or nonparallel side (the examiner was sloppy here in not insisting on a tolerance), the claim would appear not to cover it. And Doctrine of Equivalents is long gone. A reading of the elements of the claim will also suggest a few simple measurements which might even exclude the device as illustrated on the website...

Hi,

Yes you do do. It is claimed rotating something can produce
pressure waves, it clearly can't at any wavelengths exceeding
the dimensions of the rotating part. However, it is not that
that is patented (even if it was, its worthless as it is wrong).

You can't patent a principle, right or wrong.

Patents cover the implementations of an idea, not the idea,
and if the idea doesn't work, your basically going to have a
very easy time getting your useless patent approved.

Being given a patent in no way validates the patents claims.

The patentee is protected against his/her implementation
being copied, but that is pretty useless protection if it
simply doesn't work in the first place. What people can't
do is build the same thing and claim the same things,
and in this case that hardly matters, its nonsense.

rgds, sreten.

Sreten, from the claim:
Quote:
when rotated along its central axis creates a positive pressure in the surrounding medium on all sides parallel to the axis of rotation
So any device fitting this description (and the other limitations of the claim) would be covered by the patent. Of course, if we assume that basic physics applies, this won't actually happen. And of course, a sound wave is alternating positive and negative pressure, so that would seem to escape the claim as well.

A lawyer writing the patent would have helped (at least from the legal standpoint, not the physics), but John seemed very unwilling to consider that and seemed quite freaked out by my offer via email to give him a hand gratis during the pre-publication application process.

Precisely.You did not misunderstand anything. That is what is patented.
This is how you divert the reader of the patent in the hope that he or she will believe that an incredible development has been discovered that can produce high fidelity sound with only a tall thin rod rotating from side to side.
Yes it will rotate from side to side : sometimes only minutely(mid/high frequencies)and other times quite noticeably(low frequencies).

But here's the thing that many will not realise : grab the rod while it is operating, causing no ''rotation'', you will find that it still produces sound.............how can that be????

In my opinion, everything was correct:
- Patent introduces a new idea - this is the basis for the award
- Physics is one - if the square has its own weight, it also has its inertia, moving it so fast (20,000 times / second) is very difficult.
- A similar project done for a long time phenix
