But perhaps Jeremy can chime in, since he is far more qualified to share some words of wisdom than any of us.
I know very little of American law, and not much more about the English law of intellectual property.
One point I can clarify, since it's been raised. In English law, corporations are liable for torts - acts of wrongdoing - by their employees acting in the course of their duties. It's known as vicarious liability, it's been around for well over 100 years and I would be astonished if it were not a feature of American law also. The extent of an employee's duties, and whether deliberate acts also confer vicarious liability, is a fairly active area of development. The
Wikipedai article on the topic is not bad.
It's fairly clear from a reading of the first few paragraphs of the judgment that this is a highly technical area of law and the word "taking" is, in context, a term of art which should not be imagined to hold its commonplace meaning.
As far as I can tell, this photographer's greed has landed him in trouble. He was offered $2,500 for a temporary infringement which, it seems, could not be shown to have caused him any harm, but he wanted nearly 20 times as much and he chose a misguided route to getting it. Dollar signs in a client's eyes should be a big red flag to any lawyer: it indicates that the litigation is going to end in tears.
