  3. The Open Invention Network is designed to ward off attacks against Linux. Huawei could also save money with it.

  4. Inspired by the question of including an Exfat driver in the Linux kernel, Microsoft is now also examining the possibilities for this. So far, the company's patent policy has prevented acceptance.

  5. The Microsoft employee Stephen Walli describes the change at Microsoft towards open source software and Linux as culturally driven. With a view to joining the patent pool of the Open Invention Network, however, it also becomes clear that the company still has a lot of work to do.

  2. The community complains, Facebook remains stubborn at first and ultimately foregoes its own patent license for the Javascript framework React. But that doesn't make anything better, but rather worse for everyone.

  3. Widespread resistance has already formed against the planned trade agreement with the USA. Now the EU Commission itself sees that some passages are very questionable. The federal government welcomed the decision "very".

  1. The judges at the Federal Patent Court remain: Microsoft's Vfat patent is invalid due to a lack of technicality. Microsoft had previously won a counterclaim at the Federal Court of Justice (BGH). Motorola had appealed against the BGH ruling.

  2. Acta has been stopped, but the proposed EU-US trade agreement could also undermine consumer rights through the back door. Experts fear that companies will be put above the law.

  3. The source code of the Samsung Exfat driver is now available under the GPLv2 on the company's website. The previously leaked source code was apparently rightly placed under the free license, because Samsung has taken large parts of the Linux FAT driver.

  1. A month ago a kernel module for Microsoft's Exfat file system was released on Github. Now the developer admits that it is a leaked code from Samsung and thus a copyright infringement.

  2. A hitherto unknown developer has published a kernel module for Microsoft's Exfat file system on Github. So far, only drivers via fuse can be used.

  3. Law professor Clark Asay believes that the free software development model is difficult to reconcile with patent law. This makes it very difficult to build up defensive patents.

  1. They shouldn't actually exist and yet more and more are being granted: software patents in Europe. As a result, developers gradually lose the copyrighted exploitation rights to their computer programs.

  2. The parliamentary groups of the CDU / CSU, FDP, SPD and the Greens have unanimously spoken out against software patents. The federal government should ensure that software "exclusively copyright" is protected. Open source software should also benefit from this.

  3. A free version of the Exfat driver for Linux and Mac OS X has been released in version 1.0. The driver works with fuse. Since the Exfat file system is burdened by software patents, the driver will probably not be shipped with Linux distributions.

  2. Austin Meyer, developer of the X-Plane flight simulator, has been sued by Uniloc. He has ported his game to several platforms with his company Laminar Research, including Android, which is now a risk for him.

  3. Icon icon Susan Kare testified in the process between Apple and Samsung that the similarity of the symbols on Apple and Samsung devices would confuse buyers. Samsung is pursuing a strategy of excessive demand, said marketing expert Winer.

  6. According to a statement by Linus Torvalds, Microsoft's Vfat patent has been examined again by the ITC and declared invalid. Torvalds was able to prove that he had already discussed long file names in file systems on a mailing list in 1992. This would make the patent invalid because of Prior Art.

  7. The Debian project explains in five points how it will deal with software patents. The project continues to believe the patents are a threat to free software and will not publish communications about patents.

  8. The founder of the Free Software Foundation, Richard Stallman, has been critical of the plans for an EU unitary patent in a guest post for The Guardian. This could mean that patent wars in the EU, like in the USA, could become the norm.

  9. The well-known business magazine The Economist has taken Google's announced takeover of Motorola's mobile phone division as an opportunity to point out the questionable nature of software patents and the need for reform of the system in the USA.

  10. The most important US appeals court in patent disputes has confirmed the nullity of patent claims on intellectual processes in a recent decision. What pen and paper are enough for is therefore not patentable.

  13. A program for storing and evaluating cookies in order to make it easier for the user of a website to orientate himself on repeated visits with the help of lists of visited pages is not patentable. The Federal Court of Justice decided in a judgment that has now become known.

  14. The Debian project has published a guidebook on software patents. The FAQ developed together with the Software Freedom Law Center is intended to provide information and help assess risks.

  15. After Lodsys drew attention to itself with threats against some small iOS and Android developers, there are now increasing lawsuits against the company, which also sees the measurement of clicks on online advertising covered by its patents.

  16. The Open Invention Network takes on patents on server-side scripting technologies. These were developed before ASP, JSP and PHP.

  17. The Groklaw website will not be discontinued, although Pamela Jones is withdrawing as announced. He will be succeeded by law professor and former Red Hat lawyer, Mark Webbink.

  18. Apple has won an important victory in a software patent dispute. A federal court in Texas rejected the claims of the company Mirror Worlds Technologies of Yale professor David Gelernter as ill-founded.

  19. Google's Android operating system has a copyright problem. At least that's what Florian Müller thinks, who became known for his campaign against software patents, among other things. Müller relies on his own analysis and refers to a similar assessment by two US experts.

  26. The eagerly awaited decision by the US Supreme Court in the Bilski case has been disappointingly unclear. The US Supreme Court basically approved patents on software and business methods with a 5: 4 vote.

  27. The Federal Court of Justice regards practically every process that can be implemented as a computer program as technical and therefore patentable. This emerges from a current resolution on a patent application for "dynamic document generation".

  28. The Federal Court of Justice has dismissed a lawsuit from the Federal Patent Office and thus declared the patent filed by Microsoft for the use of long file names in the FAT file system to be valid. This brought the legal dispute in favor of Microsoft that had been going on since October 2006 to an end.

  1. Software patents? Declined!

    As it became apparent yesterday, the European Parliament rejected the Software Patent Directive today, Wednesday, with a majority of 648 out of 680 votes, thus ending the legislative process. Outwardly there was almost unanimous demand to prevent software patents based on the US model in Europe, but when it came to the question of how far this rejection should go, there were major differences that led to a downright lobby battle. In the end, it was agreed that it would be better not to adopt a directive instead of one that displeases the respective camp.

  2. Negative price awarded for software patents

    With the invitation to tender for the "nosoftwarepatents-award 2006", 1 & 1, GMX, mySQL, Red Hat and CAS Software want to draw attention to the dangers associated with the granting of patents for software ("computer-implemented inventions"). The call for tenders is intended to be the start of an information campaign.

  3. Lobby battle over software patents

    In the dispute over the introduction of software patents in Europe, Florian Müller was one of the protagonists as the founder of the NoSoftwarePatents.com campaign. He wrote down his story of the "lobbying battle for software patents", in May 2006 the whole thing should appear as a book on 380 pages, the corresponding website is already online today.
