Does the reason Theora is relatively safe from patent infringement 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

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

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? Who have checked that

Hi everybody, As the Asterisk community is getting larger and larger, I was wondering that the features which are provided in Asterisk and are programmed by the open source community under GPL, or GUIs like FreePBX which also come loaded with wonderful features and uses same Asterisk, are they anywhere violating any patent laws? Most of the features work the same way as Nortel, Avaya and other

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

Hello Theora developers, I'm doing some cursory research into Theora's IP status in preparation for asking 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

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

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

The specific standards process used to develop the MPEG codecs creates patent minefields that royalty-free codecs don't generally face. Because many knowledgeable people have heard of the problems faced by these patent-soup 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

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 the others.

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... US 7,142,646 B2 Voice mail integration with instant

Here in the uk, to get a patent on anything, you have to prove that the patent is not obvious and that there is no prior art. If there is prior art, then a patent cannot 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

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

AFAIK g729 patent is expiring sometime in 2019-2020.

Cologne, 10.12.00 Dear Sir, Dear Madam, We are concerned about the possibility that the European Commission might introduce software patenting into the European Community because we think this will harm our profession. We make our living on data management and statistical analyses. Modern statistics crucially depends on algorithms [cf. Venables, W. N., & Ripley, B. D. (1999). Modern applied

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.
