back to article Microsoft promises no patent prosecution of open-source .NET

Microsoft is promising not to pursue patent claims against Linux and open-source software using the open-source implementation of .NET, Project Mono. The company has said that third party implementations of its C# and the Common Language Infrastructure (CLI) - a language runtime - will be made available under its Community …

Embrace, extend, extinguish

The promise does not apply to future versions of the specification, non-required optional portions of the specification, extensions to the specification or deviations from the specification - even when those extensions and deviations are required to match Microsoft's implementation.

I do not need mono, and I will keep it that way - at least until Microsoft earns a reputation for not abusing its near monopoly in operating systems.

Remember the MS "ISO standard" Office file formats?

Its a standard

You can use it safety

Except

How many bit relied on the specifics of the Office implementation?

This is *really* starting to look like another MS Trojan Horse .

And the MS "Community Promise?" MS do contracts. Like their cross licensing ones where they kneecapped compatible makers by the number of processors, not the number of installed copies of their software (with a gagging clause so you can't talk about it).

They also do litigation. Tom Tom and the FAT file format should serve as a reminder to what happens when reckon they can shake someone down. If it's not legally enforcible MS will use this “Promise” as a method to poison the well.

We are Microsoft. All your open source belong to us.

So they say now

but, like a politician's election promise, there's nothing to stop Microsoft's beancounters further down the track from reneging on it and suing Linux into oblivion - and because they own the patent, the law would be on their side regardless of any "promises" they'd made previously.

Moreover, Microsoft have a predatory track record and their real motives here are about making Linux dependent on them so they can lock it down at some future date. They're a profit-making corporation. They are NOT doing this out of community spirit or the goodness of their hearts; they are doing it as part of a strategy to eliminate or control a competing system. Remember "Embrace, Extend, Extinguish"? They haven't changed.

No, I'm with Stallman on this one. Keep Microsoft's proprietary shit OUT of Linux.

To me this sounds much the same as when the British PM came back fro Germany with a worthless sheet of paper declaring peace. We all know what happened soon afterwards.

Promises can be broken & broken very easily. Until a non revokable commitment is written down on paper & signed by Balmer & Gates and lodged with a third part like the OIN I won't accept a word they say.

They will have to go a lot further than some weasel words probably dreampt up by some press office lackey.

Insufficient

As far as I can tell, the promise only covers the use of C# and the CLI, it doesn't cover the whole of the .NET framework. So, for example, I imagine that things like ASP.NET, ADO.NET, LINQ, WCF, WWF and so on are not covered.

These are only things I've ever been worried about.

So this doesn't go far enough for me, assuming I'm correct about coverage.

No problems

Microsoft has issued a public statement saying that they are giving up their patent rights in these situations. A judge would not allow them to renegade on that promise as they would effectively be committing entrapment and acting in very bad faith. Even if they did find a sympathetic judge the most they could probably achieve from it is an injunction preventing the infringing applications from being distributed in the future, I doubt that a judge would even award costs as they have explicitly allowed the situation to come about anyway.

I asked before on the other article

What patent? I just want to know which patent(s) MS think they can bring in to play. AFAIK, c# is a specification for a language. Is it actually that spec that is patented? (can you actually do that?) or is it part of the implementation of the language that is patented (in which case can it be got round?).

Tough luck

Mono users knew what they were letting themselves in for. C# was and is a Microsoft specific language, like Visual Basic. If there is a cross platform doohicky that sort of lets them use it on other platforms, then they do so at their own risk.

And which idiot would sign a license that accepts the validity of Microsoft's patents?

""It is common practice in the software industry to register patents as protection against litigation, rather than as an intent to litigate. Thus mere existence of a patent, without a claim of infringement, is not sufficient reason to warrant exclusion from the Ubuntu Project."

MS could simply publish a paper and hence prevent future patent attack on that subject. Lets not be so naive here, they patent to attack and counterattack and if you had a business worth attacking, you would not be immune.

When Ubuntu starts taking a greater share against Windows, then Microsoft will make the 'claim for infringement' and point out all these licenses that accepted the validity of Microsoft's patent as evidence the patent should stand.

Mono should not be in Ubuntu.

This IS legally binding

"Q: Is this Community Promise legally binding on Microsoft and will it be available in the future to me and to others?

A: Yes, the CP is legally binding upon Microsoft. The CP is a unilateral promise from Microsoft and in these circumstances unilateral promises may be enforced against the party making such a promise. Because the CP states that the promise is irrevocable, it may not be withdrawn by Microsoft. The CP is, and will be, available to everyone now and in the future for the specifications to which it applies. As stated in the CP, the only time Microsoft can withdraw its promise against a specific person or company for a specific Covered Specification is if that person or company brings (or voluntarily participates in) a patent infringement lawsuit against Microsoft regarding Microsoft’s implementation of the same Covered Specification. This type of “suspension” clause is common industry practice. "

tl;dr they can't sue you, ever

Also, Mono contains

1) parts that are covered by the ECMA standard

2) original namespaces (like Mono.Simd)

3) open-sourced Microsoft stuff (like ASP.NET, under the OSI-approved MS-PL license)

4) parts that are in .NET but not covered by the standard (like Winforms)

which is why Miguel de Icaza says they'll be splitting their distribution up into definitely safe (1 and 2) and potentially dodgy (3 and 4) packages, which is what already happens on Ubuntu for instance.

Re: Anti Microsoft paranoia

"Some people spending too long doing dental examinations of gift horses if you ask me..."

Don't you mean 'trojan horse'. The problem is, Microsoft have a pretty crappy track record, they don't really innovate, they just copy ideas and try and kill off the competition, sometimes it works (i.e. IE versus Netscape - although now Firefox is fighting back) and sometimes it doesn't (Zune vs iPod). It's all well and good that Microsoft are making a promise, but as said in other comments, it's not legally binding.

If Microsoft were not going to sue for patent infringement then why don't they join the Open Invention Network (http://www.openinventionnetwork.com/) and pass the patents along to them.

Luckily Linux is just a kernel and doesn't include Mono (as far as I know) and with thousands (if not hundreds and thousands) of applications out there released under the GPL hopefully there would be drop in replacements which don't use Mono which can be swapped in at a moments notice if Microsoft do start trying to kill off Mono (remember, the Free Software community work much faster than Microsoft in releasing software) so say if Ubuntu was blocked by patents then they could probably have a new release out without the offending software with in weeks or maybe even days (okay it would probably be KDE based rather than Gnome based considering Gnome seem to be more involved with Mono).

For once the paranoids are wrong

The MS Community Promise may sound like PR but it IS a legally binding document that they can't renege on. It applies to developers, distributors, and users without regard to the development model, copyright licenses or the associated business model of an implementation.

Possible issues come with what is and is not covered by the CP. It only covers the ECMA standards for C# and the CLI. Mono is a lot more than that and everything else is not covered - ASP.NET, ADO.NET, Winforms, etc. Also the CP only covers implementations that implement all required portions of a specification; partial implementations are not covered

@James Hughes

Given the mind-numbing cluelessness of some judges and the utterly broken nature of the US patent system, MS don't *need* to have a patent right now. The mere threat that maybe they might write one later and maybe some judge will be daft enough to uphold it is enough to put the brakes on anyone who doesn't have a legal fighting fund or a portfolio they can retaliate with.

I heard (a guy on a nearby desk used to work for the company in question) the other week about an electronics firm that lost a patent case for the "invention" of putting their kit inside a metal box to shield against interference. Apparently it was recognised that Mr Faraday might have established some prior art on the basic idea, but that using a cage *in this product* (some random box of electronics) was an inventive step.

To my mind, patent cases long ago passed the point where they were an abuse of the legal process. Where once they protected inventors and delivered a net benefit to society, they now harrass inventors and have no redeeming benefits. Reform would be fairly straight-forward, but since politicians appear to lose their intelligence the further up the greasy pole they rise, perhaps the simple abolition of all IP rights is the only likely way out. That would be a shame, since much good would be lost, but it would still be better than the present mess where IP rights can be stolen by the rich and powerful and then used to bash the original creators.

Bah Humbug

First - MS provided financial backing for Mono in the past. Mono is not just .Net on Linux, it's .Net on practically everything (Linux, Solaris, Symbian etc.).

Second Richard Stallman is not an 'Open Source Evangalist', he is a free software advocate and in his strange little world, the two are totally different. RMS has spoken out repeatedly about Open Source before conceding that it is 'Not the enemy'. He has also published a paper on the FSF website titled 'Open Source misses the point of Free Software' (http://www.gnu.org/philosophy/open-source-misses-the-point.html). Have a read of it and then tell me he has any positive influence on OSS.

@By The Mole

It doesn't even have to get to a judge. There are stages to the way MS abuses it's power and Money.

1. "leaked' rumour about litigation.

2. Threat of legal action too vague to contest.

3. leveraged 'out of court agreements' that aim to set precedents.

4. A legal action so complex that, although bound to fail, will cost too much in lawyers fees to contest.

4. A legal action so complex that, although bound to fail, takes so long to contest that it becomes a war of attrition.

5. Lobbying the government to change the law in as part of the above.

6. Attempts to change the English language so that agreements no longer mean what everybody thought they did.

These MS's stock in trade. Of course nobody trusts them.

No need for paranoia

There is no need to stress over MS lawsuits. You'll never be able to do anything useful with Mono other than display "Hello World" is a poorly rendered form.

Far, far too much of the API remains stubbed out or not even implemented.

Come back and talk to me in about 3 years when it is ready for use in the real-world.

It's a non-issue

C# / .NET adds nothing significant to Linux or computing in general. Anyone who builds anything using .NET (on Linux or otherwise) is building on a promise from a pathological liar. Legally binding in theory, but who will hold them to it in practice?

It's a shame for the people who waste their time, just like the time I've wasted learning every MS technology I've ever learned, and building everything I've ever built with those technologies.

You'd be alright with C#

You'd probably run into more difficulties if you started using some open source reimplementation of VB .NET, or something, because these extension languages are considered 'products' within Microsoft's lumpen marketing literature.

C# has been an ECMA standard for nearly a decade. What you lose, by being wedded to C# is the Common Language Runtime - which is a bit of a sham, anyway. A good .NET programmer knows how to use the classes and methods available to them, and cares little about what local dialect of loop structures and conditionals are wrapped around them; a bad one just flings together whatever visual studio offfers them, using the same linear 'yeah-but-no-but-yeah-but-no-but' IF...ELSE logic they've always used. (indeed, while the 'Tower of Babel' like prospect of inheriting some creeping horror written by 9 VB guys, a Perl programmer, two semi-retired COBOL gurus and a wierdo who writes in nothing but IronLisp, has kept most people away from considering .NET projects - especially failing ones; of which there are depressingly meany - in fact, what you find, is that it's usually the 9 VB dorks, and their total failure at abstraction, or using the right data access methods, that has caused the ship to run aground. I'm sure we've all seen the code from the guy who calls string methods on static strings: IF strMyOutput.ToLower() = "HELLO WORLD".ToLower() THEN Response.Write("I'm so full of win, I have to keep visiting the toilet, just to get rid of some of it.") END IF).

Either way, a deliberate lack of curiousity about .NET coding is almost as much of a sin as a deliberate ignorance of Linux. It reveals a lack of vision - a discomfort with travelling beyond one's comfort zone - that suggests that the comfort zone, itself, is rather more restricted than is desirable. Lack of curiousity is not a characteristic of skilled programmer. Your data doesn't necessarily want to be free, anyway, it just wants to be useful. It just so happens that one of the best ways of making it useful, is to also make it free. Even Microsoft seems to have grasped part of that message.

Legally binding, but is Microsoft legally bound?

"The MS Community Promise may sound like PR but it IS a legally binding document that they can't renege on. It applies to developers, distributors, and users without regard to the development model, copyright licenses or the associated business model of an implementation."

I don't doubt for one second that there is some hidden note or piece of legalese or other Infernal Mechanik somewhere else which can be used to invalidate this at a stroke.

Let us not forget that whilst something may be legally binding, Microsoft have largely refused to be legally bound.

This seems like MS are making a genuine attempt to reach out to the FOSS community and other OSes, in much the same way that IBM and Sun did, but it's being welcomed with a level of paranoia that makes RMS look positively sane. How come IBM and Sun were welcomed and MS are shunned? It can't be because of the dubious business practices, because they all check the box on that one.

Other companies indulge in dubious business practices to gain an advantage in their business, which is usually the business of making and selling a product or providing a service. Microsoft IS dubious business practices. Lock in is not the means. It is the end.

@ AC 15:55 (RE: What's the problem?)

>why was .NET created in the first place?

.NET was created to create a Common Language Interface (CLI) across all MS supported languages. This included VB(.NET), C++, and C#. It allowed all of them to be compiled into the same "binary" file, which is essentially just an XML document that controls a Common Language Runtime. This would be able to run on all current and future versions of MS Windows without the fear of DLL Hell. In short, it was MS' way of crushing Java.

>What gap did it fill that was not already filled?

.NET resolved a large complaint from Win32 programmers - DLL Hell. By basing everything against a common library that supported previous implementations, a program written for Windows 2000 would work, drag-and-drop, with Windows Vista (or Windows 2052). This encountered hiccups (Framework 1, 1.1 to 2) but has steadied into something (amazingly) reliable with 2.0 - 3.5.

>What is its purpose?

.NET was always implicitly designed to run on other machines besides the desktop. This might have been officially limited to WinMobile or EmbeddedXP, but it has always been expected to run on other POSIX compliant operating systems. Yes, that's right. NT was POSIX compliant and so, too, are all NT kernel based WinOS's (2L, XP, etc). What are other examples of POSIX compliant operating systems? UNIX and Linux.

Is this for the OSS, FSF, or Linux communities? Heck NO! This is to allow the large user base of WinOS developers to drop WinOS apps into Linux and Unix environs with little or no code change, or even change in development style or language. I can imagine Bill laughing at the thought of all the WinOS cowboys frolicking in the Linux Wilds... and the terror in Torvalds and Stallman at the same thought.
