Nvidia releases Alias-Free GAN code and pre-trained models, naming it StyleGAN3
From the license file:<p>> 3.4 Patent Claims. If you bring or threaten to bring a patent claim against any Licensor (including any claim, cross-claim or counterclaim in a lawsuit) to enforce any patents that you allege are infringed by any Work, then your rights under this License from such Licensor (including the grant in Section 2.1) will terminate immediately.<p>Is such a clause legal? I have basically zero knowledge of such things, but it seems like it should be illegal to punish someone for a good faith patent claim.
