Juno Therapeutics, Inc. et al. v. Kite Pharma, Inc.
(Docket #: 2020-1758)(Fed. Cir. 2021)(PDF, 19 pages)
A chemical patent that discloses just two particular compounds (of a large class of compounds) that bind to particular targets does not provide sufficient written description support for a claim that covers the entire genus of compounds from the class that binds to the particular targets, particularly when the patent description provides no other means of identifying which compounds of the compound class would bind to which targets, such as common structural characteristics or shared traits.
In Re: Vox Populi Registry Ltd.
(Docket #: 2021-1496)(Fed. Cir. 2022)(PDF, 11 pages)
The gTLD (generic top-level domain) ".SUCKS" cannot be registered as a standard character mark because it is only a non-source identifying part of a domain name and thus does not function as a mark.  The stylized version of ".SUCKS" also cannot be registered because it is merely a different font style and thus does not create an inherently separate commercial impression from the word itself, but such a stylized mark could potentially become registered if the applicant is able to prove acquired distinctiveness.
