wikinerd writes "I interviewed Alexander Noe, developer of the open source PxScan and PxView utilities. He recently received a cease-and-desist letter by Shinano Kenshi, the Japanese company which controls Plextor. His utilities provide similar functionality with PlexTools, sending special command sequences to Plextor DVD recorders that activate special features such as media quality check."

Look at Broadcom. They hold their hardware specs a closely guarded secret [for the most part] and the net affect is you can only use their wifi stuff [reliably] in windows... The problem is without the drivers the hardware has zero customer value. But giving out free drivers lets you SELL hardware since it now has value.
The sad thing it isn't even that you have to write the damn drivers. In the OSS world of BSD/Linux the kernel contributors would GLADLY write a driver for free if it meant they could use some quality hardware with the respective OS. So all it costs the hardware manufacturer is describing the interface [at the high level] of how to talk to the hardware. Since these documents are ROUTINELY produced internally so the software teams can write their windows drivers all it means is you re-brand the

The existence of an open source application that jiggers the proprietary doohickeys on my device is potentially an useful aid to my competition. It may help them figure out may trade secrets, or to divine strategies equivalent to or better than the ones I use for my patented technologies.
It's not much help to my competitors; in practical terms it is indistinguishable from zero help. On the other hand the cost of sending a chest thumping C&D on official stationary to some private individual is practically indistinguishable from zero too.
So when in doubt, turn the crank on the lawyer box and spit out another C&D. It's cheap and risk free, and keeps your legal staff in practice for when you really need them.

Nikolaos S. Karastathis: Hello, please introduce yourself and briefly describe the utilities you developed.
Alexander Noé: I'm Alexander Noé:, currently studying computer science at TU-Chemnitz. The utilities PxScan/PxView i've developed perform error scans on Plextor PX-712/716 and Plextor Premium drives. The tests are the same, but PlexTools had some handling I didn't like, for example you can run several tests on DVDs, but in PlexTools you couldn't trigger them at once, but rather had to trigger one test at one time. My goal was just to make all that more convenient.
Nikolaos S. Karastathis: You received a letter via email about these utilities. Who sent the letter and what did it say?
Alexander Noé: The letter was sent by lawyers working for Shinano Kenshi. The Lawyers claim those utilities would violate their clients rights.
Nikolaos S. Karastathis: Have you replied to this letter?
Alexander Noé: No, I haven't.
Nikolaos S. Karastathis: Why do you think the lawyers sent this letter, and what are their requests?
Alexander Noé: Plextor maybe sees me as competitor. However, they don't offer any Linux version, neither free nor for money, so I have absolutely no idea what their problem with pxlinux could possibly be. They demand that I cease-and-desist from any further infringements, and demand that I comply a list of all steps I've taken to ensure that their clients' rights will no longer be infringed.
Nikolaos S. Karastathis: Have you contacted a professional lawyer yet? Did you receive any legal advice?
Alexander Noé: A professional lawyer said that in his opinion, none of the accusations made by Shinano are justified.
Nikolaos S. Karastathis: Is the letter confidential, can you post it for everyone to see?
Alexander Noé: The letter itself is not explicitely marked as such, but I'm not sure if I have the right to publish an email sent to me in general without the sender agreeing on this.
Nikolaos S. Karastathis: In the last years there are increasingly more legal problems for free/libre/open-source software projects. Now software patents may be introduced in Europe. What are your views on this issue?
Alexander Noé: I *really* hope that software patents will not be introduced, but I can't do much about it... as I don't really understand lawyer and politician language, like most people, I can hardly assess the consequences software patents would cause, but it wouldn't make life of free developers easier.
Have your say! Discuss in Wikinerds Forum (unregistered users are welcome).
Nikolaos S. Karastathis: What do you plan to do now?
Alexander Noé: I'm waiting what will happen....
Nikolaos S. Karastathis: Anything more you want to say?
Alexander Noé: Considering that Plextor did, not long ago, announce that they would be supporting open-source, I really wonder what all this is supposed to be about. Either they support open-source, or at least "tolerate" it, or they don't.
Nikolaos S. Karastathis: The interview appears to be finished. Thank you very much!

Also, doesn't one have the right to make public any legal threat against oneself, like a C-and-D letter. Are those protected by copyright, or (likely) not, as they are functional not creative, and are a legal document (the law often favors legal documents being public) and in addition, one might want to make it public to defend themselves.
chillingeffects.org might be a good place to go.
I had bought a Plextor CD-RW a while back. It is the last Plextor product I will ever buy (*). I will convince other's to boycott also.
(*) Unless they repudiate their C-and-D letter, promise to never do that again, and release specs on all proprietary commands to the public without any license on those specs which restricts their use in free software.

An email? (Score:5, Interesting)
Seriously, serious legal threats usually don't arrive via email. Lawyers usually prefer to speak with certified letters and such, where they know it was received and who received it and when (and can prove it in court), and so in general anything received via email should be taken with a big grain of salt. Email is too unreliable (my spam filter ate it!) and just hasn't been around enough decades to make the legal system trust it. At most, they might send a certified letter and an email at the same time (and so the email will arrive first) but I suspect that even that's rare.
The email may be legitimate, and in this case it sounds like it probably is, but even so ... big grain of salt.

What Plextor is up to (Score:4, Insightful)
Next, they probably have some lawyers trolling the net, sending cease and desists to anyone writing "competing" software. This is a sadly common CYA issue, and is done more to demonstrate they've been actively protecting their patents and copyrights than anything else. If this is the case, a few e-mails between the developer and Plextor could resolve the problem and allow the software to continue being developed, assuming Plextor doesn't want the product squashed.
Then again, this could all be about unauthorized use of the Plextor name or graphics on the developer's web site. They could be doing this to protect their corporate branding, and to keep people from thinking the software is authorized or supported by Plextor.
Has anyone contacted Plextor about this?
You've fogotten the details (Score:5, Informative)
Plextor may be doing a couple things. First and foremost, they're making sure no unauthorized Open Source projects spring up. They have no interest in supporting the software unless they wrote it. I can understand this motivation. We all remember the Mandrake Linux release that killed some CD RW drives, and Plextor is no doubt concerned about a similar problem for them.
Plextor would have nothing to fear if they've followed the ATAPI / MMC specifications correctly. Those drives that died (I had one) implemented something like a firmware flash (or "trash") command using the same opcode as the write cache flush command (or something similar, the details in my head are fading). On a CD-ROM drive, write cache flush obviously is unnecessary, however, that doesn't mean that the opcode can be grabbed to be used for something else. The CD-ROM manufacturer was the root cause of this problem.

Even if they explicitly tell him not to do so, he can still make public the information in the letter.
They have copyright on the letter. What he needs to do is paraphrase the letter, with attribution, and quote only the most unbelievably stupid parts.
As for the original program, they need to tell him which specificy rights of theirs he is violating. The is no such thing as generic "intellectual property". There are only copyright, patent, trade secret, trademark, and contractual rights.
Unless they have a patent on the method his program uses to perform the activity his program performs, or he's violating an NDA or using their trademark, they can't stop him from performing the activity.
Bottom line: they can't stop him from publishing his code, only theirs. Using the same methods they use doesn't violate their copyright.

"...Plextor is strongly committed to supporting the Open Source Software movement with free development tools that help speed the creation of next-generation Linux-based video software," said Dirk Peters, director of marketing, Plextor. "The release of this SDK was a direct response to requests from the user community for an easier way to work with Plextor ConvertX video capture devices on computers running Linux..."
"Plextor's new Linux SDK provides developers with a free GPL-based full-source driver to support all of the popular V4L2 applications," said, Tom Luax, vice president of sales, WISchip International. "The combination of low-cost MPEG4/DivX Video compression hardware and Linux OSS software is a great solution for anyone who wants to build a high-quality and low-cost personal video recorder for their PC..."
Yes, I realize this is for PVR stuff, not DVD burners, but one would think their strategy would be a bit broader than product-by-product. Maybe they think their PVR offerings need more help, while their DVD burners don't.

It just takes about 2 mins to write a decent e-mail, do it now and speak up for the little guy.
SCSI commands (Score:3, Insightful)
According to the cdfreaks website, the PxLinux software simply uses a series of SCSI commands to retrieve statistical data from the drive. The same principle would also apply to ATAPI.
The SCSI command set is a set of published specifications specifically intended for such purposes. It cannot reasonably be the case that Plextor, the drive manufacturer, by following these specifications, expected to restrict the use of SCSI commands for drive control.
It's possible that there is some sort of exclusive software development agreement between Plextor and Shinano Kenshi, but that agreement is not binding on other parties.
It would also be possible, in principle, to sell these drives under condition not to use them except as strictly specified, but again such an agreement would not be binding on other parties.
In no case is it reasonable to seek damages against some third party who independently develops a means to use a manufactured device as intended. An impossible situation would clearly develop for both industry and the public at large if courts were to award such damages.

One of your members is starting a new project, called
PXscan, PXview or PXTool Linux.
This contains unauthorised usage of Plextor-owned
intellectual property and should be refused.
If accepted, we will take legal steps.

Hmm.. "Mr. Your rights online" Hemos is a wonderful censor and deleter of content, isnt he?
I guess depleting a 'business venture' of some big company is more worth saving than a free software developer. Well, either that, or MMC3 scsi commands are now considered "propertiary secrets".
