(1) A purchaser of goods acquires all title which his transferor had or had power to transfer except that a purchaser of a limited interest acquires rights only to the extent of the interest purchased.
The part you're quoting refers to the recipient being the fraud, not the seller. The recipient never acquires more rights than the seller had. This is why stolen goods can be seized by police, even from innocent purchasers.
[Edit:] Actually more complicated than that. The provision contemplates the middle-man acquired the rights to the goods sold through fraudulent means. In this case, it still requires the middle-man to have acquired the rights from the original seller in a transaction in which the seller gave up the rights to the goods. I.e., theft by fraud would suffice but mere theft would not. It's hard to explain theft by fraud. In a nutshell, the original seller is deceived as to one or more details of the transaction itself, such as price, identify of the seller, or even as to what they are exchanging. The UCC expects all parties to a contract governed by the UCC to exercise due diligence with respect to a contract, so if the transaction includes the "stolen" goods, the UCC doesn't provide any relief. Generally in a situation like this, it would happen where the language of the transaction clearly would include the goods at issue, but the middleman misrepresents to the original seller that those goods aren't included in the contract.
"Suppose Ed takes his bicycle to Merv, a bicycle dealer, for repairs, but instead of making repairs Merv sells the bicycle to Betty. Who now owns the bicycle? Section 2-403(2) states that "[a]ny entrusting of possession of goods to a merchant who deals in goods of that kind gives him power to transfer all rights of the entruster to a buyer in ordinary course of business." Ed has entrusted possession of goods to Merv, a merchant dealing in goods of that kind. Assuming Betty is a buyer in the ordinary course of business (BIOC), Merv now has the power to transfer all of Ed's rights in the bicycle to Betty. Betty now owns the bicycle, and Ed cannot validly assert any ownership claim against her. Ed's only remedies would be against Merv."
Guys, the UCC isn't the only law that applies to the situation...
Ed might not have rights under the UCC, assuming it applied to the transaction, which is questionable since Ed does not appear to be a merchant. He would have rights under state laws that override the provisions of the UCC.
[Edit] Most states actually override this provision of the UCC to define entrusting narrowly. See, e.g, California's provision:
3) “Entrusting” includes any delivery and any acquiescence in retention of possession for the purpose of sale, obtaining offers to purchase, locating a buyer, or the like; regardless of any condition expressed between the parties to the delivery or acquiescence and regardless of whether the procurement of the entrusting or the possessor's disposition of the goods have been such as to be larcenous under the criminal law.
(2) Any entrusting of possession of goods to a merchant who deals in goods of that kind gives him power to transfer all rights of the entruster to a buyer in ordinary course of business
We need to know more about how the seller acquired the goods. Often such ebay sales are by people who had legitimate possession, just not any right to sell them. This is why experimental and demo electronics aren't normally investigated as stolen goods. Nobody should be selling them, nobody had the right to sell them, but a great many merchants do legitimately possess them.
We need know nothing about the person selling the stuff on ebay. It's irrelevant how the ebay merchant got the goods, what matters is how the manufacturer gave up the goods.
If it was theft--easy case. Stolen property is not covered by UCC. (It's the Uniform Code of Contracts, so there must be a chain of contracts connecting the property from the manufacturer to the innocent buyer for the UCC to apply.)
If it was theft by fraud--now we're talking. This could mean, for example, that the eBay merchant ordered the goods from the manufacturer but then never paid, or lied about who they were, or some other such misrepresentation or fraud or crime. In this case, there's a chain of contracts, so an innocent buyer from the eBay merchant would be protected by the UCC. (Note that if the eBay merchant knowingly does not pay, it could be both theft or theft by fraud depending on the jurisdiction and specific circumstances.)
It actually says:
