...th 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 parts of it; and people could probably use the patented algorithms in FreeType without being worried about a suit. I for one doubt that Theora truly does not infringe on some patent or other, because I believe that the way the patent system works today, it is impossible to write anything of significance without accidentally "trespassing" on t...

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

...country that recognizes patents. > > You mean countries that recognize software patents, right? 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. In local laws we even are allowed to reverse-engineer software for needs of compatibility and interoperability. So, writing code for commercial codec and using it for interoperability with hardware devices (you purchased) is allowed by law. Damn, we even have a law that don't allow bittorren...

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

...sterisk soultion for a customer, 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...

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

...loped 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 patents or WHAT is actually patented, because such specific state...

First, we (Xiph.org, me) obviously did not patent Speex. Also, during development, we were careful not to use techniques known to be patented and we searched through the uspto database to see if anything we were doing was covered. The only thing we haven't done yet for Speex is an "official" (done by a lawyer) patent search. If anyone is interested in funding such effort, that would be appreciated. That being said, we cann...

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

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

...urprised 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. This indicates that you will not be sued if you use Theora which basically is what people are interested in knowing. /Ole -- The Patented Word Processor http://ole.tange.dk/swpat/ ---------- Forwarded message ---------- From: D Richard Felker III <dalias@aerifal.cx> Date: Wed, 23 Mar 2005 17:55:35 -0500 Subject: Re: [Theora] troll or truth ?
