Back in October 2019, the GNOME project announced they had been hit by what they called a patent troll with Rothschild Patent Imaging. Now it seems it has been resolved and it's a big win for open source.
The problem was with the Shotwell image management application, as Rothschild claimed it infringed on their patents. Yesterday, GNOME announced a "walk-away settlement" that not only drops the case against GNOME but both Rothschild Patent Imaging and Leigh Rothschild in the case will now grant a "release and covenant" to any software released under an OSI (Open Source Initiative) approved license which covers the entire Rothschild portfolio of patents. That's a nice win for FOSS developers.
From the GNOME press release:
Neil McGovern, Executive Director for the GNOME Foundation said "I’m exceptionally pleased that we have concluded this case. This will allow us to refocus our attention on creating a free software desktop, and will ensure certainty for all free and open source software in future."
Leigh Rothschild said "I’m pleased that we have managed to settle this issue amicably. I have always supported the innovation of open source software and its developers and encourage its innovation and adoption."
As an added bit of info, OpenUK spoke with GNOME's McGovern in The Register, where they mentioned that it covers over 100 patents. This is thanks to a crowdfunding campaign GNOME did that helped to raise over $150K for the defence.
