I don't disagree, but we also TM bananas (Chiquita and Del Monte). What is that signaling? I'm guessing no product differentiation whatsoever. quality? not unless there are inferior alternatives. And I don't think it's status.
I mean, I don't know if you're being serious here. But by protecting investments in status signaling (by making simulacra illegal), trademark law is going to encourage more status signaling. The upside, of course, is that we also TM's "merchandising shortcut." That is ... 1/

okay, I'm convinced.
Trademark law has *a lot* to do with it. It's a massive social subsidy for social stratification through Veblen consumption.
but does trademark have much to do with it? isn't it the same as Thorstein Veblen's big front yards of untilled ground? ("conspicuous consumption"). Probably easier to fake a Rolex than a big yard.

Teaching trademark this semester and wondering, for the nth time, why anyone thinks it's laudable to be in the business of making fancy accessories that allow rich people to signal status.

I'm not a good predictor, but I have doubts. I don't think that even this SCT wants to extend Trinko to remedies, and the less-restrictive alternative issue seems to be more words than substance.
How attractive will this issue be to the court in your opinion?

Google's cert. petition agnst Epic Games (10-27, 9th Cir.) asks whether rule of reason antitrust plaintiff has a burden to prove a less restrictive alternative; and also attacks the notion that Trinko's refusal to deal doctrine does not apply to remedies. www.documentcloud.org/documents/26...

In Academy of Allergy, 2025 WL 2886701 (6thCir. Oct. 10, 2025) the court held that the SCT’s indirect purchaser rule (in this case “indirect supplier”) precluded an antitrust action against a harmful cartel. A concurrence lamented that fact. It’s time to overrule Illinois Brick.

CoStar, 2025 WL 2573045 (9thCir) refused to dismiss a complaint alleging that monopoly power for Sherman Act §2 purposes could be inferred simply from the fact that D persistently charged higher prices than its rivals for years, saying nothing about margins or output restrictions.

Yes, it's a win for Google, but I think a win for U.S. technology and its users as well, as well as appropriate recognition by the court that messing around with market structure in a market as dynamic as this one could spell disaster.
Basically the only remedies are a ban on continuing the exclusive deals already found unlawful and a one-time obligation to share a part of Google's search-index (but not its quality rankings) with competitors.

The BrwnShoe factors for antitrust market definition can send judges to insane lengths to twist them. See Harley-Davidson, 2025 WL 2374859 (dissenter would find relevant market by interpreting BShoe's "unique production facilities" factor to mean "American made.").

In Gibson the 9th Cir problematically rejected an antitrust claim that the “hub” in a hub-and-spoke conspiracy provided hoteliers with nonpublic price information and the hoteliers (“spokes”) agreed to “abide by” its pricing algorithm’s recommendations. cdn.ca9.uscourts.gov/datastore/op...

In Papa John's the court provisionally certified a class action of franchise food employees subject to a no-poach agreement; the court assumed that it was unlawful per se. Papa John's Employee and Franchisee Antitrust Litig., 2025 WL 225564 (WDKy. 8-7-2025).

all true and maybe here too. Do you agree that the chances of SCT review on the market definition issue are extremely slim?
Nested markets are fine if the facts support both. I could imagine, for example, markets for colas, all soft drinks, and all beverages. If all satisfy the hypothetical monopolist test, conduct that harms competition in any one of them (or more than one) would presumably violate the antitrust laws.

In the Google Play case they court rested on the jury's finding of an "Android-only" relevant market. The earlier case challenging the same conduct by Apple found a market for "mobile game transactions" that included both Android and Apple. Can both of them be correct?

EpicGames decision is a good example of a secondary refusal to deal, which should be treated more like tying rather than refusal to deal, where liability is hard to get. The "tie" is not reachable classically, because there is no agreement; instead, it is created by code.

In Quinton v. Amex, 2025 WL 1994848 (EDNY 7-7-2025) the court admitted testimony that Amex's anti-steering rule was unlawful "cross-subsidization" -- a rare case permitting theory that a pure wealth transfer from poorer to wealthier customers could be an antitrust violation.
