The USPTO recently issued additional guidance regarding
submission of digital specimens of use as well as rejections of
generic.com marks.
Examination of Specimens for Use in Commerce: Digitally
Created/Altered or Mockup Specimens
Examination Guide 3-19, originally released in July 2019, aimed
to address the issue of fake specimens – that is, specimens
that are actually digitally created/altered or mockups and do not
evidence actual use of the mark on goods sold or transported in
commerce or in connection with services actually rendered in
commerce. To identify fake specimens, the USPTO looks for
over a dozen of characteristics that may indicate the specimen was
created for the sole purpose of registering the mark, such as
pixilation around the mark, a screenshot of a website without a URL
or browser tab, a superimposed mark, or a digital rendering of
products.
