A Chinese Copyright Infringement Case: "Since GPL-Based Software Products Already Have an Obligation to Disclose Source Anyway, Isn't It Fine to Copy Them?"

Mon, 23 Sep 2024 00:00:00 +0000

As the use of open source software has spread widely, the legal issues surrounding it have grown increasingly complex. In particular, the question of copyright over derivative works based on open source projects that use a copyleft license such as GPL (GNU General Public License) is a thorny subject for many companies. A recent software copyright infringement lawsuit in China offers important implications for this issue.

French Court Orders Major Telecom Orange to Pay Damages for GPL Violation

Mon, 19 Feb 2024 00:00:00 +0000

Hello.

Today I want to look at a case in which a French court ordered the telecom company Orange to pay damages for violating the GPL. This case seemed especially worth noting for two main reasons.

First, the defendant in this case is Orange, a major telecom operator. (Since I work at a telecom operator myself…)
Second, while GPL violation lawsuits mostly arise in embedded devices, in this case the open source at issue was used to build a B2B web service. This underscores that open source license compliance matters across every area of software development.

Through these aspects, this case looks set to reaffirm the importance of open source license compliance. It stands as an important example emphasizing that companies must thoroughly understand and comply with license requirements when using open source.

China's First GPL Lawsuit Case: VirtualApp

Hello, this is Haksung Jang.

In September 2021, it was reported through a Chinese news article that the first GPL-related ruling in China had been handed down. I’ve summarized what I understood of it using a translation tool. Please keep in mind that, since I’m not a lawyer and don’t know Chinese, there may be errors in the content. :) If you find any errors, I’d be grateful if you’d let me know at any time (haksung@sk.com).
