The United States Supreme Court issued several decisions yesterday that may be of interest:

• Twitter, Inc. v. Taamneh and Gonzalez v. Google LLC – social media companies are not liable for terrorist attacks by hosting accounts from terrorists: “To impose aiding-and-abetting liability for passive nonfeasance, plaintiffs must make a strong showing of assistance and scienter. Plaintiffs fail to do so.”
• Andy Warhol Foundation for Visual Arts, Inc. v. Goldsmith – copyright fair use does not cover Warhol’s use of a photograph by Goldsmith to create a silkscreen portrait of Prince -> “the purpose of the Orange Prince image is substantially the same as that of Goldsmith’s original photograph. Both are portraits of Prince used in magazines to illustrate stories about Prince.”
• Amgen Inc. v. Sanofi – patent enablement -> “Amgen’s claims sweep much broader than the 26 exemplary antibodies it identifies by their amino acid sequences. Amgen has failed to enable all that it has claimed, even allowing for a reasonable degree of experimentation
