The Software Freedom Law Center said that it has filed suit against two companies for allegedly violating the General Public License which covers usage of Linux and thousands of other free and open-source products.

The suits are the second and third time that the non-profit foundation has filed suit, signaling a willingness to use the court system to enforce the GPL.

The plaintiffs are two programmers--Erik Andersen and Rob Landley--who wrote BusyBox, software covered by the GPL version 2 often used in conjunction with the Linux operating system in embedded devices.

The suit was filed against Xterasys and High-Gain Antennas, which both manufacture wireless communications hardware.
