The opportunities are endless
I spotted this near the beginning of their submission:
" Software for creating, editing, uploading, downloading, accessing, viewing, posting, displaying, tagging, blogging, streaming, linking, annotating, indicating sentiment about, commenting on, embedding, transmitting, and sharing or otherwise providing electronic media or information via computer the internet and communication networks;"
It seems to me that Amazon's look-inside facility might fall foul of this. There is a bit of me that hopes that their application succeeds. Think of the number of products and services that could sport a "Original name annoyed Zuck" logo as a badge of honour. I would cheerfully trademark such a logo myself, in order to put it restriction-free into the public domain.
