...ingement lawsuit have more to do with it actually not being encumbered, or is it because its use is decentralized? For example, FreeType is not patent-free, nor is Linux, yet they succeed because on the one hand, they are open source, and those who maintain them do not guarantee anything regarding patents, it is up to each individual user to deal with those issues; and on the other hand, the very fact that it's not one but many infringers makes it far more difficult for a patent troll to extract anything. People use Linux even though Microsoft (for example) is known to have patents that cover pa...

Hi, We are in the business of developing/productizing Multimedia codecs for embedded systems. Recently, Vorbis has gained good popularity. We are also developing it. But we face few problems related to patents. Vorbis claims to be patent free. Is there any particular search made for possible patent infringements and corresponding report published? We need to convince our customers sometime about this issue. I have started with patents listed on the website of "www.mp3licensing.com". Some of t...

As resident of country where the file is hosted - yes we don't have software patents, they have been proposed to EU and reject few years ago. So by law - software is algorithm and can't be patented.

Hi all, <p>i have readed all the realy sad stuff about software patents in europe and what allread exists. There is one side related to speex and i dont know if this is allready discussed here. Take a look at: http://swpat.ffii.org/patents/effects/voip/index.en.html Is speex realy petant free or does patent free only means that is is not patent by the speex authors?...

..., is there any violation of any patent or copyright laws anywhere? Of if I use my own Asterisk server to provide services to some customers, am I violating any patent laws by not paying the royalties to some patent owners? I heard people saying that IVR technology is patented and google search for patents also say so. But we all are using IVR for ourselves and our customers without paying royalties to anyone. But when it comes to using g729, all of a sudden royalty issue comes in. So what is right to use and what is not? -- Zeeshan A Zakaria -------------- next part -------------- An HTML attachm...

Hi there, I am new to Ogg/Theora and am trying to compare several video codecs as part of my master thesis at the University of Klagenfurt. Therefore I have a question: will there be any patents problems using Ogg/Theora in the future? Is/will Ogg/Theora stay free from patents rights? This would be a great advantage in using Ogg/Theora instead of e.g. H.264 which is covered with numerous patents right now. Thanks, Kuge

...king Apple to reconsider the possibility of shipping an implementation. I have a few questions and I'm hoping knowledgeable people can help out. 1) What are the terms of any patent licenses or disclaimers, and do they have field of use restrictions or limitations on code for which the patents are licensed? I found the following patent license in the original VP3.2 source: <http://svn.xiph.org/branches/vp32/vp32/VP32_license.txt >. This appears to have a sort of field-of-use restriction on the patent license terms; products that don't support the original VP3 bitstream d...

I did some research on patent claims on range and arithmetic coding. The original range code pdf presented in the UK by an ibm employee at the time asserts no patent claims what so ever. If there are patents I cant find em. I have the original paper in PDF if anyone cares to see it. Its a good candidate for encoding because browsing a few of the implememntations avaialable on line, I can roll my own and I think the speed would be acceptable. BTW, the speed of rangecoding over arithmetic is really not...

Hi everyone, first of all, I searched through the archives for any posts resembling this, I didn't read all posts about the patents so if this has been suggested before I apologise. I read in an article on C|Net (I think, it was linked from Slashdot anyway) that Thompson are threatening to sue you if Ogg Vorbis becomes a success. Which is evil, and I'm also mad at them because they never answered my mail (which was about h...

...standards, they may extrapolate these risk to codecs developed under a different process where these problems are less considerable. This is a mistake, and I'll explain why here. Recently there have been a number of prominent statements along the lines of "all video codecs are covered by patents" and "virtually all codecs are based on patented technology". These statements are carefully engineered FUD spread by the license holders of competing formats in order to discourage the use of unencumbered alternatives. They are careful to avoid naming WHO owns these supposed patent...

Sprint Nextel is sueing vonage, voiceglo and theglobe.com for infringing on VoIP patents. Sprint Nextel claims to have about 100 patents on VoIP technologies. Does anyone know which ones this article is talking about, and if so does asterisk have any of those features? The reason I am asking is that the article is vague, Vonage uses a fairly standard codec set, I dont know about t...

I've dug down as far as I could on www.uspto.gov for anything remotely close to what is going on with Verizon and all searches end with only two possibilities in regards to what is going on. So unless the patent was issued to someone else and Verizon bought it, these are the only two possible patents this case could be based on...

...be given, this is why people patenting stuff have to keep it a secret until they actually have the patent, otherwise it is considered to have been released into the public domain. Once something is in the public domain, nobody can patent it. OTOH I don't think that the u.k recognises software patents anyway, and I suppose things might be different worldwide? I think there might be a lot more variation in patent law as opposed to copyright law. I don't think anyone could claim a patent on anything in Vorbis that they don't already have a patent on. It's far too publically available...

I suppose it could be possible to patent something and let the patent expire so that it is registered at the patent office but not enforcable. No one else could patent it then. I get curious about the RLE patent. I heard Someone has a patent on run length encoding and I wonder how long they have had it because I remember RLE code running on a sinclair spectrum in the 80's before the whole

...This is a modern service oriented business: it's about selling intellectual service, not about selling 'intellectual property'. However, software patenting threats this business, as nobody doing that type of work has the time or resources to check whether an algorithm might violate any patents. Checking for equivalence between algorithms is a non-trivial task, and often it is less time consuming to program an algorithm than to search and buy it. And once we have created it on our own, we might want to improve it and share it or even sell it. We do not see any contradiction between patent...

The list probably did not get this reply from D Richard Felker III. Having read quite a few patents I tend to agree with Richard: Software patents are very broad and even if I have not read the source code of Theora I would be surprised if it did not infringe several patents. However, I believe the argument that On2 has not been sued for infringing the MPEG-patents is a very strong argument. Th...
