Report from the Geniatech vs. McHardy GPL violation court hearing
Today, I took some time off to attend the court hearing in the appeal hearing related to a GPL infringement dispute between former netfilter colleague Partrick McHardy and Geniatech Europe
I am not in any way legally involved in the lawsuit on either the plaintiff or the defendant side. However, as a fellow (former) Linux kernel developer myself, and a long-term Free Software community member who strongly believes in the copyleft model, I of course am very interested in this case.
History of the Case
This case is about GPL infringements in consumer electronics devices based on a GNU/Linux operating system, including the Linux kernel and at least some devices netfilter/iptables. The specific devices in question are a series of satellite TV receivers built by a Shenzhen (China) based company Geniatech, which is represented in Europe by Germany-based Geniatech Europe GmbH.
The Geniatech Europe CEO has openly admitted (out of court) that they had some GPL incompliance in the past, and that there was failure on their part that needed to be fixed. However, he was not willing to accept an overly wide claim in the preliminary injunction against his company.
The history of the case is that at some point in July 2017, Patrick McHardy has made a test purchase of a Geniatech Europe product, and found it infringing the GNU General Public License v2. Apparently no source code (and/or written offer) had been provide alongside the binary - a straight-forward violation of the license terms and hence a violation of copyright. The plaintiff then asked the regional court of Cologne to issue a preliminary injunction against the defendant, which was granted on September 8th,2017.
In terms of legal procedure, in Germany, when a plaintiff applies for a preliminary injunction, it is immediately granted by the court after brief review of the filing, without previously hearing the defendant in an oral hearing. If the defendant (like in this case) wishes to appeal the preliminary injunction, it files an appeal which then results in an oral hearing. This is what happened, after which the district court of cologne (Landgericht Koeln) on October 20, 2017 issued ruling 14 O 188/17 partially upholding the injunction.
All in all, nothing particularly unusual about this. There is no dispute about a copyright infringement having existed, and this generally grants any of the copyright holders the right to have the infringing party to cease and desist from any further infringement.
However, this injunction has a very wide scope, stating that the defendant was to cease and desist not only from ever publishing, selling, offering for download any version of Linux (unless being compliant to the license). It furthermore asked the defendant to cease and desist
- from putting hyperlinks on their website to any version of Linux
- from asking users to download any version of Linux
unless the conditions of the GPL are met, particularly the clauses related to providing the complete and corresponding source code.
The appeals case at OLG Cologne
The defendant now escalated this to the next higher court, the higher regional court of Cologne (OLG Koeln), asking to withdraw the earlier ruling of the lower court, i.e. removing the injunction with its current scope.
The first very positive surprise at the hearing was the depth in which the OLG court has studied the subject matter of the dispute prior to the hearing. In the many GPL related court cases that I witnessed so far, it was by far the most precise analysis of how Linux kernel development works, and this despite the more than 1000 pages of filings that parties had made to the court to this point.
Just to give you some examples:
- the court understood that Linux was created by Linus Torvalds in 1991 and released under GPL to facilitate the open and collaborative development
- the court recognized that there is no co-authorship / joint authorship (German: Miturheber) in the Linux kernel as a whole, as it was not a group of people planning+developing a given program together, but it is a program that has been released by Linus Torvalds and has since been edited by more than 15.000 developers without any "grand joint plan" but rather in successive iterations. This situation constitutes "editing authorship" (German: Bearbeiterurheber)
- the court further recognized that being listed as "head of the netfilter core team" or a "subsystem maintainer" doesn't necessarily mean that one is contributing copyrightable works. Reviewing thousands of patches doesn't mean you own copyright on them, drawing an analogy to an editorial office at a publisher.
- the court understood there are plenty of Linux versions that may not even contain any of Patric McHardy's code (such as older versions)
After about 35 minutes of the presiding judge explaining the court's understanding of the case (and how kernel development works), it went on to summarize the summary of their internal elaboration at the court prior to the meeting.
In this summary, the presiding judge stated very clearly that they believe there is some merit to the arguments of the defendant, and that they would be inclined in a ruling favorable to the defendant based on their current understanding of the case.
He cited the following main reasons:
- The Linux kernel development model does not support the claim of Patrick McHardy having co-authored Linux. In so far, he is only an editing author (Bearbeiterurheber), and not a co-author. Nevertheless, even an editing author has the right to ask for cease and desist, but only on those portions that he authored/edited, and not on the entire Linux kernel.
- The plaintiff did not sufficiently show what exactly his contributions were and how they were forming themselves copyrightable works
- The plaintiff did not substantiate what copyrightable contributions he has made outside of netfilter/iptables. His mere listing as general networking subsystem maintainer does not clarify what his copyrightable contributions were
- The plaintiff being a member of the netfilter core team or even the head of the core team still doesn't support the claim of being a co-author, as netfilter substantially existed since 1999, three years before Patrick's first contribution to netfilter, and five years before joining the core team in 2004.
So all in all, it was clear that the court also thought the ruling on all of Linux was too far-fetching.
The court suggested that it might be better to have regular main proceedings, in which expert witnesses can be called and real evidence has to be provided, as opposed to the constraints of the preliminary procedure that was applied currently.
Some other details that were mentioned somewhere during the hearing:
- Patrick McHardy apparently unilaterally terminated the license to his works in an e-mail dated 26th of July 2017 towards the defendant. According to the defendant (and general legal opinion, including my own position), this is in turn a violation of the GPLv2, as it only allowed plaintiff to create and publish modified versions of Linux under the obligation that he licenses his works under GPLv2 to any third party, including the defendant. The defendant believes this is abuse of his rights (German: Rechtsmissbraeuchlich).
- sworn affidavits of senior kernel developer Greg Kroah-Hartman and current netfilter maintainer Pablo Neira were presented in support of some of the defendants claims. The contents of those are unfortunately not public, neither is the contents of the sworn affidavists presented by the plaintiff.
- The defendant has made substantiated claims in his filings that Patrick McHardy would perform his enforcement activities not with the primary motivation of achieving license compliance, but as a method to generate monetary gain. Such claims include that McHardy has acted in more than 38 cases, in at least one of which he has requested a contractual penalty of 1.8 million EUR. The total amount of monies received as contractual penalties was quoted as over 2 million EUR to this point. Please note that those are claims made by the defendant, which were just reproduced by the court. The court has not assessed their validity. However, the presiding judge explicitly stated that he received a phone calls about this case from a lawyer known to him personally, who supported that large contractual penalties are being paid in other related cases.
- One argument by the plaintiff seems to center around being listed as a general kernel networking maintainer until 2017 (despite his latest patches being from 2015, and those were netfilter only)
Withdrawal by Patrick McHardy
At some point, the court hearing was temporarily suspended to provide the legal representation of the plaintiff with the opportunity to have a Phone call with the plaintiff to decide if they would want to continue with their request to uphold the preliminary injunction. After a few minutes, the hearing was resumed, with the plaintiff withdrawing their request to uphold the injunction.
As a result, the injunction is now withdrawn, and the plaintiff has to bear all legal costs (court fees, lawyers costs on both sides).
For me, this is all of course a difficult topic. With my history of being the first to enforce the GNU GPLv2 in (equally German) court, it is unsurprising that I am in favor of license enforcement being performed by copyright holders.
I believe individual developers who have contributed to the Linux kernel should have the right to enforce the license, if needed. It is important to have distributed copyright, and to avoid a situation where only one (possibly industry friendly) entity would be able to take [legal] action.
I'm not arguing for a "too soft" approach. It's almost 15 years since the first court cases on license violations on (embedded) Linux, and the fact that the problem still exists today clearly shows the industry is very far from having solved a seemingly rather simple problem.
On the other hand, such activities must always be oriented to compliance, and compliance only. Collecting huge amounts of contractual penalties is questionable. And if it was necessary to collect such huge amounts to motivate large corporations to be compliant, then this must be done in the open, with the community knowing about it, and the proceeds of such contractual penalties must be donated to free software related entities to prove that personal financial gain is not a motivation.
The rumors of Patrick performing GPL enforcement for personal financial gain have been around for years. It was initially very hard for me to believe. But as more and more about this became known, and Patrick would refuse to any contact requests by his former netfilter team-mates as well as the wider kernel community make it hard to avoid drawing related conclusions.
We do need enforcement, both out of court and in court. But we need it to happen out of the closet, with the community in the picture, and without financial gain to individuals. The "principles of community oriented enforcement" of the Software Freedom Conservancy as well as the more recent (but much less substantial) kernel enforcement statement represent the most sane and fair approach for how we as a community should deal with license violations.
So am I happy with the outcome? Not entirely. It's good that an over-reaching injunction was removed. But then, a lot of money and effort was wasted on this, without any verdict/ruling. It would have been IMHO better to have a court ruling published, in which the injunction is substantially reduced in scope (e.g. only about netfilter, or specific versions of the kernel, or specific products, not about placing hyperlinks, etc.). It would also have been useful to have some of the other arguments end up in a written ruling of a court, rather than more or less "evaporating" in the spoken word of the hearing today, without advancing legal precedent.
Lessons learned for the developer community
- In the absence of detailed knowledge on computer programming, legal folks tend to look at "metadata" more, as this is what they can understand.
- It matters who has which title and when. Should somebody not be an active maintainer, make sure he's not listed as such.
- If somebody ceases to be a maintainer or developer of a project, remove him or her from the respective lists immediately, not just several years later.
- Copyright statements do matter. Make sure you don't merge any patches adding copyright statements without being sure they are actually valid.
Lessons learned for the IT industry
- There may be people doing GPL enforcement for not-so-noble motives
- Defending yourself against claims in court can very well be worth it, as opposed to simply settling out of court (presumably for some money). The Telefonica case in 2016 <>_ has shown this, as has this current Geniatech case. The legal system can work, if you give it a chance.
- Nevertheless, if you have violated the license, and one of the copyright holders makes a properly substantiated claim, you still will get injunctions granted against you (and rightfully so). This was just not done in this case (not properly substantiated, scope of injunction too wide/coarse).
For years, your former netfilter colleagues and friends wanted to have a conversation with you. You have not returned our invitation so far. Please do reach out to us. We won't bite, but we want to share our views with you, and show you what implications your actions have not only on Linux, but also particularly on the personal and professional lives of the very developers that you worked hand-in-hand with for a decade. It's your decision what you do with that information afterwards, but please do give us a chance to talk. We would greatly appreciate if you'd take up that invitation for such a conversation. Thanks.
