On a forum I asked any people knowing softwares laws what they think about OBOS, and the "BeOS" trademark at Palm that can give problems in the futur. I receive an answer from a spanish lawer specialized in Intellectual Properties issues. The thing is a bit long, but is very interesting. Everyone interested on the "possibles" OBOS legal issues should take a look at this. ------------------------------------ By Marques I am an Intellectual Property lawyer at Spain. As you have already pointed out the only serious legal issues that may arise are those of the BeOS trademark because of its possible association with OpenBeos. In the other hand, I know the OBOS team are being very cautious with the coding. Copyright covers Originality, it's not a Patent system as many tend to think (Patent covers inventions, software is explicitly excluded on all modern copyright laws), no first to file at copyright (under the Berna Convention there is no filing obligation) nor first to create, it is about creating originally (not by vile copying, we spaniards say "servil"), whenever that is done. A great joke that fully explains the "vile" character: Harper's new monthly magazine, November, 1873. Editor's Drawer: "Tony [The Earl of Shaftesbury, making a speech at Exeter Hall] was asking the children a variety of questions of a Scriptural nature, to which he had received very satisfactory answers. Just as he was concluding, he addressed a girl somewhat older than the rest, and among other things inquired, `Who made your vile body?` `Please my lord`, responded the unsophisticated girl. `Betsy Jones made my body, but I made the skirt myself!`" See? She made the skirt herself, no vile deed, full copyright, just as OBOS, Betsy's descendants now work at Palm Inc. The Lord copyright is another tale. The key is creating, if you create something similar to do the same thing there is no infringement, copyright does not cover functionality, it covers expression. Of course the expression is not an strict concept, for you may not elude copyright by mere accidental alterations, that would be fraudulent. If I were to look for possible infringements of the BeOs copyright I would try to argue one of these two: - OBOS is some kind of BeOs "derivative work" without authorization. - OBOS has done illegal and unauthorized BeOs reverse engineering. Mine would be the proof burden. Derivative Works I am following the OBOS development, and by what I see it is being a clean cloning, starting by the NewOS kernel, the app-server, the media kit, the file system, translation kit, everything is being coded from scratch or reused from open software. That kind of coding is no mere accidental alteration, it is the complete creation of a hole new system designed to function on a similar manner to BeOS. It is A NEW ORIGINAL CREATION. It is not a derivative work, for OBOS have not taken to "derivate" the code they don't have. The most common cases of derivative works are translations, in order to translate you need the original text. Reverse Engineering Reverse Engineering is the "star" of the USA DMCA (Digital Millenium Copyright Act), and as you already know the rest of the world follows. The USA jurisprudence about it used to allow many cases of fair use, specially under Interoperability cases: Atari vs Nintendo, Fed. Cir. 1990 Sega vs Accolade, 9th Cir. 1992 Bateman vs Mnemonics, llth Cir. 1996 Needless to say after the DMCA, the legal guideline is DON'T EVEN TOUCH IT, the fair use is now as narrow as an EULA. The mere possession of SoftIce is Evil. So what? So I don't think Palm would get into a reverse engineering battle versus an open source OS, in a similar way (not an identical manner) MS doesn't go after WINE, it would be very nasty, very unpractical, not easily probated, and even the `interoperability fair use` may after all prevail in Court. I believe Apple would litigate, if they are nuts enough to order the removing of Apple-like theme screenshots, what would they not do? THEMES!!! How third class of you Steve! (his expression). Fortunately Apple themes are `really` only banned for only a 1-2% of desktop users. And then talk about porting OSX to x86 as the great thing! (not for computing freedom), to worse. Hehehe! can't help mentioning the Redmonds, have you read the legal papers at Lindows.com? Go read them, exactly what I was saying but better, much better!!! Those rejected PTO applications are BEAUUUUUUUUTIFUL!!! And I love the Microsoft Computer Dictionary definition of "Windows", EXHIBIT A is gold. `Good Morning MS I'll be your Server today!` (LindowsZilla). Concerning the trademark point, in the worst of cases OBOS would make a great trademark, like OBOS NOT BEOS, this is not recursive but equally understood. No damages would result before a legally protocoled notification (a formal one) asking to stop using the OpenBeOS trademark. And as said, OBOS would have no problem in my opinion. Open and Beautiful. Excellent work at OpenBeos. GO OBOS!!! GO!!! --------------------------------------------------------------
