Although the first version of the GNU GPL was released by Richard Stallman back in 1989, and version 3 was issued in 2007, there have been surprisingly few court cases examining it and other open source licenses, and whether they are legally watertight.

A key case is Jacobsen v. Katzer from 2008. As a detailed Groklaw post at the time explained, the US appeals court held that open source license conditions are enforceable as a copyright condition. Now we have another important judgment, Artifex v. Hancom, that clarifies further the legal basis of open source licenses. It concerns the well-known Ghostscript interpreter for the PostScript language, written originally by L. Peter Deutsch, and sold by the company he founded, Artifex Software. Artifex was a pioneer in adopting a dual-licensing approach for Ghostscript. That is, you could either use the software under the GNU GPL, or you could avoid copyleft's redistribution requirements by taking out a conventional proprietary license.

Hancom is a South Korean company that produces Hangul, word-processing software that is primarily used in South Korea as an alternative to Microsoft Word. Artifex says that Hancom incorporated Ghostscript into its Hangul software, but neither sought a proprietary license, nor complied with the terms of the GPL by releasing the source code for the application that incorporated Ghostscript. As a result, Artifex took legal action, alleging copyright infringement and breach of contract. Hancom asked the court to dismiss Artifex's complaint on several grounds, but they were all denied. The most significant ruling is on Hancom's claim that the GNU GPL was not a contract. In her order, embedded below, Judge Jacqueline Scott Corley wrote:

The GNU GPL, which is attached to the complaint, provides that the Ghostscript user agrees to its terms if the user does not obtain a commercial license. Plaintiff alleges that Defendant used Ghostscript, did not obtain a commercial license, and represented publicly that its use of Ghostscript was licensed under the GNU GPL. These allegations sufficiently plead the existence of a contract.

    Use, not distribute. Copyright prohibits any redistribution without a license. And the license granted by the GPL is contingent upon the contract.
