How (and Why) To Wrap Your Head Around Free Software Licensing

Filed under
OSS

Open source software is being taken seriously as a viable alternative to expensive proprietary applications but it's important to realize that, like its commercial brethren, it comes with a license for use. It's also important to remember that all open source licensing is not created equal.

Free software licensing is quite complex and I recommend browsing gnu.org for the most up-to-date and complete information. According to Eran Strod, director of product marketing at Black Duck Software, around 70% of open source code is licensed under the GPL, something you'll want at least a passing familiarity with.

Although the GPL is popular, it's not the only game in town.

Patent Troll Kills Open Source Project On Speeding Up The Computation Of Erasure Codes

Via James Bessen, we learn of how a patent trolling operation by StreamScale has resulted in an open source project completely shutting down, despite the fact that the patent in question (US Patent 8,683,296 for an "Accelerated erasure coding system and method") is almost certainly ineligible for patent protection as an abstract idea, following the Supreme Court's Alice ruling and plenty of prior art. Erasure codes are used regularly today in cloud computing data storage and are considered to be rather important. Not surprisingly, companies and lawyers are starting to pop out of the woodwork to claim patents on key pieces. I won't pretend to understand the fundamental details of erasure codes, but the link above provides all the details. It goes through the specific claims in the patents, breaking down what they actually say (basically an erasure code on a computer using SIMD instructions), and how that's clearly an abstract idea and thus not patent-eligible.
