I apologise for the length of this post (and continuing to keep this thread alive), but I have an personal interest in this area of law. Nikodemus, by using your post as a basis for my commentary I do not wish to demean the research you have done, but simply to clarify some of the points you've made.
First let me say that if you are concerned about infringing copyright and/or patent law you must contact a lawyer. Most large practices have specialists who deal with intellectual property rights. Patent advice tends to be more specialised and for that you will need to contact a patent attorney.
In otherwords, DO NOT depend on the advice given in this forum. So now I have asked you to clearly ignore everything I say, here is my understanding. Note that I only have an understanding of UK Law, and related International conventions. Also note that I am not a lawyer, and again you should seek proper legal advice.
Nikodemus interpretation of the information in the URLs is broadly correct. Here are some notes, and some responses to the issues raised.
Nikodemus wrote:Here are some URLs I found that keep it pretty simple. They are based on US law, but the differences world-wide are not huge.
Actually, I disagree with this. The legal position in the US is very different that in the UK and this is why it is important to get proper legal advice. US law is for the most part prescriptive, the UK is not. In other words, your legal position in the UK may not be clear cut, thus the requirement for legal advice.
Nikodemus wrote:Trademarks is pretty straightforward - you cannot pretend to be a branch of Woolworhs if you are not; or say the jeans you sell are Levis if they are not. Etc etc.
Partially correct. You cannot use the Woolworths of Levis trademark, on your goods. Other aspects of this are covered by Company Law which stops you from passing off your own work as others in circumstances where trademark law does not apply. For example I could create a Levi graphic which was substantively different from the Levi brand and would not breach trademark law. Under this circumstance I would fall foul of company law as I would arguably be materially impacting the Levi brand.
Nikodemus wrote:Inventions can & must be explicitly patented. You cannot patent an idea or theory, but you can patent a specific application of it. ...
However, I don't think anyone can patent something that is already public knowledge (not sure of that though). I presume there are guidelines for what makes one design sufficiently different from a patented one to be ok. ...
Some magic gimmicks could probably be patented. Eg any physical device. Probably not things like gimmicked cards though.
You cannot patent a design which is already in the public domain. Note that because of how the term public domain is used in the UK, a design can be both secret and in the public domain, although this does not relate to the issue at hand.
There are no guidelines as granting of the application is under the objective control of the patent registrar. The invention must be substatively different, a legal term which could will cost you bug bucks if you need to go to court.
I disagree with gimmicked cards not being patentable. This almost certainly does not occur due to cost of a patent application. For example, a single patent would cost me about £10,000 and thats for the US only. It is probably a straightforward commercial decision which stops gimmick producers from patenting their designs.
In the case of large David Copperfield type illusions, there is a clear cut commercial case for a patent application, and the protection it provides.
Nikodemus wrote:If two or more people produce similar works independently, then this probably is NOT a breach of copyright. Copyright is all about deliberate plagiarism (not sure where the burden of proof lies though).
If two authors creating similar works independently, copyright vests with both creators related to their own work. Unless, one creator can prove that the others work is a derivative of their own. As I understand it the burden proof lies with the complainant.
Nikodemus wrote:Copyright lasts a fixed time i think (100 years?????)
Copyright Lasts for 70 years after the death of the copyright owner(s).
Nikodemus wrote:So... If I copy large sections of a book or DVD and call it my own I am probably in breach of copyright.
But if I express the authors ideas in my own words, I am not.
If you copy large sections of DVD or book and call it your own you are most certainly in breach of copyright.
Expressing an idea in different words is acceptable but would need to be substantively different from the original. This is an important term which we cannot define clearly (this is why you need the advice of a lawyer).
Nikodemus wrote:A lot of what people do in practice, is legally meaningless.
I'll disagree, but I know what you mean.
Everything people do in practise has legal meaning, but generally this is overriden by commercial requirements. Legal work for the most part is posturing.
If I create a small gimmick, I will simply not bother to patent it, because I am unlikely to recover the large expense of executing a patent application. I am therefore unprotected but luckily this is the case for my competition, so market forces prevail.
I cannot comment on the Criss angel story as I do not understand the background.
For arguments sake lets imagine a similar situation. I could understand the magic outlets actions being determined by the following drivers:
*They do not want to engage in any legal action due to the expense (even if they have a case).
*They do not want to discontinue or impact any existing or future relationship with a well known brand.
*They do not want any negative press to impact their brand. Theft is a serious accusation for any business, whether its true or not. A very recent case comes to mind.
As you stated previously you cannot copyright an idea only the expression of an idea. I am therefore free to discuss the DL and its variants at length, as long as my description is substantively different from other expressions, so that I am not deemed to have derived the work. I can perform public domain routines based on those sleights, or of course my own.
I broadly agree with your final statement. You do credit a magician due to ethics. It not only shows respect but also stops any inference by other magicians that you have stolen anothers work.
Pablo Picasso wrote:Good artists copy; great artists steal.
Thats a quote by the way and is fair use. Also note in quoting your message I am technically in breach of your copyright. Although it is clearly defensible in court as fair use (honest!). What Picasso was expressing was the that in moving forward, an art work is by definintion derivative. To move magic forward we need to take what has gone before and move it forward. We should do this with the upmost respect to those who have gone before. Am I saying this is a big fat gray area, oh yes I am.
To return to the original question...Yes you can make a tape and explain ID and sell it, as long as you do not breach other copyright material (now thats a get out, isnt it).
Will it cause you legal problems, maybe. But remember you can be legally challenged, whether the opposition have a case or not. You not only need to be right, you need to be able to afford to be right.
Historically, I believe that the ID is derived from the Brainwave deck orginated by Dai Vernon (surprise surprise). I could not find any patents related to the deck itself and none are declared on the documentation provided with the product. Any patents that do exist will almost certainly be related to the production of the deck itself. Since the hand made version of the deck predates the product, I doubt this is patented. Lets face it we can all make our own invisible decks if we could be bothered.
Be very careful when performing other peoples routines though. If I pick up the instructions from the ID and publically perform them, I am technically in breach of copyright law. This is called a transformation; in other words if I take copyright material in one media and move it to another the original copyright owners rights still apply.
Did you now that when you perform your ID routine your in breach of copyright? Actually your not, thats why I used the term technically. It can clearly be argued that the instructions convey the right to perform the routine publically. This may not be so clear cut if I perform them on a DVD and sell it though.
So thats the position (for what its worth), and heres your choices:
* Publish and be damned.
* Get advice from a lawyer (some cash required).
* Get in bed with a publisher/dealer who will hopefully have more experience of this subject area.
If I were to produce my own DVD I would certainly get advice from a lawyer regarding the finer points of copyright law. I would advise you to
do the same.
Clear as mud. Good luck and keep us up to date with your progress.
NOTE to Admin, you should probably put an acceptance Creative Commons copyright usage as part of the registration terms and conditions. I would advise [link]http://creativecommons.org/licenses/by-nc-sa/2.5/[/link]. Just a thought.
