Tomcat You're deliberately reducing things to absurdities. Intellectual property is not some mechanistic thing with rigid definitions set in stone. There's a lot of nuance and all sorts of contexts involved. That's why every dispute on ip infringement is different, it's considered in its specific context.
For example, read what u.s. copyright office has to say about fair use criteria. Notice how the general tone is not about strict rules and accurate definitions. It simply can't be. The nature of ip rights is complex, sensitive and nuanced.

The drawback of this, of course, is that with more persuasive (aka expensive) lawyers you can more easily stretch things in your favor π That's probably why many people believe that copyright is something that exclusively benefits evil corpos.
