Open Source Projects

In the software industry, a distinction is made between proprietary and open source software. While open source software is available on the market for use by anyone, proprietary software created individually for third parties can be licensed for a fee. This can result in problems where a connection is made between the open source software and the proprietary software. The ability to use open source software freely involves an implicit acceptance of a license agreement for use, which imposes certain obligations on the user. The most striking obligation is "copyleft" in some license agreements, which obligates the user to provide the entire source code of the completed product freely to third parties. This is a consequence that is frequently unwanted, and in some cases definitely needs to be avoided.
 
When combining several open source products, the license conditions that apply to each of them may not be compatible with each other. This may mean that the license is considered not to have been granted. To use the software in that case would be copyright infringement.
 
We plan and provide support for your software projects in order to avoid problems of this kind and to identify solutions. In the event of a dispute, we will help you with conflict resolution, out of court, and where necessary, in court.
 
It should also be noted that, contrary to the general view, software can also be patent-protected so that when using certain technologies, patent licenses must be acquired from patent pools or individual patent holders. We assist in analyzing the necessary licenses and in determining which the best license for each use is. Here too, we can provide support in case of conflict, both in and out of court.
