Adobe almost certainly has patents covering aspects of Photoshops design and tools?

Microsoft famously has patents covering aspects of the ribbon interface in Microsoft office, which of course this suite must implement. https://en.wikipedia.org/wiki/Ribbon_(user_interface)#Patent...

Meanwhile, Wikipedia has a policy that says screenshots of applications have to be "as small a version as possible" in order to meet the fair use exception for presentation of copyright work. I can only imagine an exact clone of the interface could be similarly ruled to infringe on Adobe's intellectual property.

Copyright is so flawed... This would mean an hommage is a breach of intellectual property in general, even if you paint it completely differently (say watercolor vs oil)
