If Apple was the driving force that is evidence enough to name them. It doesn't mean the suit will be successful. The DOJ doesn't win them all. Apple may be guilty of something else in this situation too but since they ultimately had no power to actually set the prices I don't get price fixing.
Ok lets use a real world example then. Lets drop back 10 yards and talk about what is legal price fixing. And yes I know that doesn't exist but give me some leeway for a bit to explain.
Manufacturer Suggested Retail Price (MSRP) is a legal disclaimer. It means, this is the price we "suggest (wink wink)" you sell the product for but you don't have to legally (drat). The reason the seller doesn't have to follow MSRP is simple. The seller owns the inventory it is selling. The product no longer legally belongs to the manufacturer. That covers about 80+% of all retail sales.
Now, how do we get legal price fixing from that? Lets get specific now. The iPhone 4 was introduced to Verizon Wireless in Feb 2011. If you bought the iPhone 16GB from VZW off contract, it was $650. If you bought it from Apple it was $600. Why was there a price difference? VZW signed a contract to sell X number of phones at X price. The phones legally still belonged to Apple and VZW was acting as a consignment seller. That means for VZW to make a profit, it had to mark the phone up. And it did. Now at any time, VZW could have bought the entire contract out. And VZW would then own the inventory. That would allow them to set any price point they wanted going forward. BUT Apple could then legally refuse to sell them any more phones after that point. Everything being done is 100% legal.
Now we have shown what MSRP is and why you can sell below it. And what legal price fixing is and why it isn't illegal.
So why is Apple being accused of "price fixing" if the manufacturer is setting the price? The manufacturer can set the MSRP. The manufacturer can exercise contracts as I have shown. And the seller can exercise his right to buy the inventory and sell the inventory at any price point. But Apple made one mistake and removed the legal rights of the other seller. By having the manufacturer sign a contract that specifically states you can not sell your product thru any other venue without our price being the lowest, you just removed the legal rights of all the sellers involved with inventory of that product.
Apple is dictating what price point Amazon has to sell its legally owned inventory at. Apple didn't make the product. Apple isn't involved in the manufacturing process of the product. Amazon doesn't even have a contract with Apple concerning that specific inventory.
And that is why Apple is being sued for price fixing.
