I always wondered why companies never made a serious attempt at the diplomatic approach. Hiring a lawyer to come after someone is going to be costly, since ya know, lawyers are not cheap. If the company already has lawyers on staff, it may be worth sending a strongly worded email to see if the owner will panic at the thought of a lawsuit and cough it up.
In the event that this scare tactic does NOT work, this is when a bit of diplomacy can come into play. Figure out how much it is going to cost you, the true cost, to go after this guy. If you can work something out with them at a cost that is cheaper than sending a pack of lawyers after the owner, why not attempt it?
The article speaks to a fan and an artist, so there was more leverage for Noel to bargain with his squatter. If company X produces a good, why not offer a bit of cash and maybe a few free products to win them over? If not, you can always go tie up the legal system with everyone else, and wait months upon months.
Or you can try a more human approach. Could be much cheaper and considerably faster. People assume because it's a company and not an individual, that they know what they are doing. The company is made up of you and I, people. People make mistakes, and companies are the worst offenders when it comes to this type of situation.
