Looking to learn more about open source licensing? Here’s what this involves, how it can benefit your business, and why non-compliance with open source licenses can be a major issue.

What Is an Open Source License?

Open source licensing revolves around the definition of a software license. With any license, the authors of the software hold the copyrights, which gives them legal authority over it and any derivative work. By comparison, open source licenses give everyone the rights to use, modify, and distribute every part of the software, from the source code to executable binaries.

To maintain clarity on open source licensing, the Open Source Initiative (OSI) came up with the Open Source Definition. This formal definition outlines all the criteria needed to establish whether a software license qualifies as open source.

Types of Open Source Licenses

Every open source project has its own license, and there are currently over 200 OSI-approved licenses. However, these licenses tend to fall into one of two types: permissive and copyleft.

Permissive Licensing

Beyond allowing users to use, modify, and distribute the software, permissive licenses allow developers to incorporate the source code into their projects, including proprietary software. These licenses don’t impose attributions, obligations, or alternative use. Popular permissive licenses include the MIT license, the Apache 2.0 license, and the 3-Clause BSD license.

Copyleft Licensing

The main thing that sets the copyleft licenses apart is their reciprocity clauses. They require any derivative works to be distributed under the same licensing as the original software. In effect, this means that the copyleft licenses limit your ability to use permissive or proprietary software. The most common example of copyleft licensing is the GNU General Public License (GPL).

Benefits of Open Source Licensing

Open-source licensing comes with a variety of benefits for businesses. These include:

• Cost savings: open-source software doesn’t come with licensing fees
• Community support: open-source projects often have active communities
• Flexibility: businesses can adapt the software to meet their needs
• Transparency: you can audit open-source software for vulnerabilities
• Faster innovation: open-source encourages experimentation and collaboration

Risks of Non-Compliance The biggest risk of using open-source licenses is that non-compliance can have serious consequences. These include:

• Legal consequences: failure to comply can lead to lawsuits and injunctions
• Financial penalties: penalties add up quickly, particularly with legal fees in the mix
• Reputational damage: news of non-compliance tends to spread quickly
• Loss of IP rights: some licenses have provisions that may lead to forfeiting IP rights
