The USPTO issued a new examination guide titled "Generic.com Terms after USPTO v. Booking.com."
The guide sets out procedures for examining applications for
generic.com terms, which are any combination of a generic term and
generic top-level domain designating an entity or information, such as
“.com” or “.biz.”
These procedures were updated in light of United States Patent and Trademark Office et al. v. Booking.com B. V.
You can find the exam guide on the Trademark examination guides page of the USPTO website. For questions about the guide, email TMPolicy@uspto.gov.
