Great article, similar to a blog post I did recently. This is a minor nitpick and shouldn't be read as an overall criticism of the author or this post, which is better than the one I did. However, I will note that non-infringement and title are, in fact, implied warranties in the UCC. I'm not sure why the author missed it. https://www.law.cornell.edu/ucc/2/2-312
Minor correction: Under UCC § 2-312(3) (link in parent), non-infringement is an implied warranty only if the seller is a "merchant," i.e., one who regularly deals in goods of the kind. The implied warranty of noninfringement can be disclaimed under § 2-316, and vendors almost universally do so (preferring to make specific express warranties instead when they perceive a market need). https://www.law.cornell.edu/ucc/2/…
The UCC nerds are out in force this round!
