Minimum Advertised Price restricts only the price a reseller may advertise or display, not the price at which it may actually transact. Resale price maintenance restricts the transaction itself. In the United States that distinction, combined with the way a MAP policy is usually implemented, is the difference between a lawful programme and an antitrust exposure. In the European Union the distinction barely helps you at all.

The reason is structural. US law asks whether there was an agreement. EU law asks whether competition was restricted by object. A unilateral announcement backed by nothing but a refusal to keep supplying you satisfies the first question and fails the second.

Price monitoring itself is lawful in every regime covered here. What creates liability in the EU is using monitoring data to pressure, sanction or coerce resellers on price. Watch all you like; do not weaponise what you see against a reseller's pricing.

That single sentence is the practical takeaway for any brand with a monitoring programme, and it is worth stating plainly before any of the case law: the visibility is not the risk. The intervention is.

Leegin made resale price maintenance defensible, not legal

For most of the twentieth century Dr. Miles Medical Co. v. John D. Park & Sons Co., 220 U.S. 373 (1911), made vertical minimum-price agreements per se illegal under Section 1 of the Sherman Act. Leegin Creative Leather Products, Inc. v. PSKS, Inc., 551 U.S. 877 (2007), overruled it. Such restraints are now judged under the rule of reason, weighing the restraint's history, nature and effect, and the Court recognised genuine procompetitive justifications: inducing retailer services, preventing free-riding on those services, and facilitating new entry.

It is worth being precise about what changed. Leegin did not make resale price maintenance legal. It made it defensible. A minimum-price agreement can still be condemned under the rule of reason, particularly where retailers rather than the manufacturer were the impetus for the restraint, or where the manufacturer has market power.

Colgate is the safe harbour, and it is a narrow one

United States v. Colgate & Co., 250 U.S. 300 (1919), holds that Section 1 requires an agreement. A manufacturer acting unilaterally may announce in advance the prices at which it will permit resale, and refuse to deal with anyone who does not comply. There is no agreement, so Section 1 is never engaged. That protection holds in all fifty states, including those that treat resale-price agreements as per se illegal under their own law.

Two cases define the boundary. In Monsanto Co. v. Spray-Rite Service Corp., 465 U.S. 752 (1984), the Court held that terminating a discounter after complaints from other distributors does not by itself prove a price-fixing agreement; there must be evidence tending to exclude independent action. In Business Electronics Corp. v. Sharp Electronics Corp., 485 U.S. 717 (1988), an agreement to terminate a price-cutting dealer was held not per se illegal absent agreement on the specific price. Complaints, monitoring and even termination following complaints do not by themselves establish an agreement.

No negotiation, no discussion, no agreement. A manufacturer that negotiates compliance, extracts promises to raise prices, or reinstates a dealer on assurances of future compliance has manufactured the very agreement that forfeits Colgate protection.

State law is where the real risk sits

Leegin governs only federal law, and several states diverge sharply.

• Maryland enacted the first Leegin repealer in 2009, expressly making minimum resale price maintenance per se illegal under state antitrust law, and its Attorney General signalled active investigations in 2023 and 2024.
• California's position under the Cartwright Act is unsettled after Leegin, with state and federal courts split; the Attorney General has pursued resale price maintenance as per se unlawful.
• New York has treated such arrangements as unenforceable and its Attorney General has pursued them, though courts generally apply a rule-of-reason-like standard.

The consequence for a national programme is decisive. Because a bilateral agreement can be per se illegal in California, Maryland and elsewhere, national brands almost universally choose a unilateral Colgate policy, which is lawful everywhere precisely because it involves no agreement.

Where the agencies are looking now

Federal enforcement against vertical minimum pricing has been rare in the modern era, and FTC guidance simply restates Leegin. Current attention is on algorithmic and surveillance pricing: a joint DOJ and FTC strike force on unfair and illegal pricing, the DOJ's RealPage action on algorithmic coordination, and the FTC's 2024 Section 6(b) study. These are largely horizontal and consumer-protection matters, but they signal that algorithms used to coordinate or enforce prices are under scrutiny.

Article 4(a) and the 2022 block exemption

Regulation (EU) 2022/720, in force since 1 June 2022, gives vertical agreements a safe harbour where neither party's market share exceeds thirty per cent and the agreement contains no hardcore restriction. Article 4(a) makes resale price maintenance — imposing, directly or indirectly, a fixed or minimum resale price — exactly such a restriction. That removes the whole agreement from the exemption and creates a presumption of illegality by object which is very unlikely to be rescued by an individual exemption under Article 101(3).

Maximum and recommended resale prices remain permitted, but only so long as they do not, through pressure or incentives, operate in practice as fixed or minimum prices. That qualifier is where most programmes come unstuck.

Paragraphs 187 and 189 name MAP directly

The accompanying Guidelines on vertical restraints bring MAP inside the prohibition. Paragraph 187 gives a non-exhaustive list of indirect mechanisms and treats MAP as one of them: prohibiting a distributor from advertising below a supplier-set level may constitute an indirect form of resale price maintenance. Paragraph 189 explains why — a MAP restricts the distributor's ability to inform potential customers about available discounts, which eliminates a key parameter of price competition. The same paragraph lists the company MAP keeps.

• Fixing the distributor's margin, or the maximum discount it may grant.
• Making rebates or reimbursement of promotional costs conditional on observing a given price level.
• Linking the prescribed resale price to competitors' resale prices.
• Threats, intimidation, warnings, penalties, delayed or suspended deliveries, or contract termination in relation to a given price level.

A narrow efficiency defence does exist. Paragraph 197 gives examples capable in principle of satisfying Article 101(3): inducing distributor promotion of a genuinely new product, a coordinated short-term low-price campaign of typically two to six weeks in a uniform format such as a franchise, and for MAP specifically, preventing a distributor using the product as a loss leader. In practice the defence is narrow, fact-dependent, and the burden sits on the supplier.

Paragraph 191 protects the monitoring

This is the paragraph that matters most to any brand running a monitoring programme. Price-monitoring and price-reporting systems — including those using pricing algorithms and monitoring software, and whether operated by the supplier or by a third party — do not in themselves constitute resale price maintenance. They increase market transparency.

Illegality attaches only when monitoring is combined with measures that fix or enforce a resale price, that is, when the data triggers the threats, warnings, penalties, delayed deliveries or terminations listed at paragraph 187. The Guidelines do note that a monitoring system can make resale price maintenance more effective and is a common feature of such arrangements — but monitoring alone is not enough for a finding.

The fines are the clearest guide to the line

In July 2018 the Commission fined four consumer-electronics manufacturers a combined 111,155,000 euro for online resale price maintenance: Asus, Philips, Pioneer and Denon & Marantz. Each had pressured or sanctioned online retailers who priced low, through threats, blocked supply and retaliation. The Commission specifically emphasised the amplifying role of pricing algorithms — because many retailers used repricing software that automatically matched the lowest price in the market, pressure on a handful of low-pricing retailers propagated across the whole market.

In October 2025 it fined Gucci, Chloe and Loewe a combined 157,373,000 euro. The brands had restricted independent retailers, online and offline, from setting their own prices — imposing recommended retail prices as de facto minimums, capping maximum discount rates, dictating sale periods and at times prohibiting discounts entirely. All three monitored retail prices and intervened on deviations. Under the cooperation procedure Gucci received a fifty per cent reduction, Loewe fifty per cent and Chloe fifteen.

National authorities are at least as active as the Commission, and their decisions are the more useful reading because they describe the mechanics.

• France: the Autorite de la concurrence fined Rolex France 91,600,000 euro in December 2023 for a decade-long ban on online sales by authorised retailers.
• Poland: UOKiK fined Karcher 26m zloty in January 2023 for setting minimum and fixed resale prices in an infringement that began in the late 1990s, and in the Oltens case found the company monitored partners' online offers through price-comparison platforms and, for repeated violations, suspended deliveries or blocked platform access.
• Germany: the Bundeskartellamt fined roughly 21m euro across musical instruments in 2021, and nearly 6m euro against Sennheiser and Sonova in May 2025 — noting that end-consumer prices were constantly monitored and intervened on.
• Portugal: Super Bock Bebidas, a board member and a director were fined 24m euro in July 2019 for fixing minimum resale prices, upheld on appeal in September 2023 and producing the 2023 Super Bock ruling from the Court of Justice.

The United Kingdom after Brexit

The UK regime remains closely aligned. The Chapter I prohibition of the Competition Act 1998 mirrors Article 101, and the Vertical Agreements Block Exemption Order 2022 replaced the retained EU regulation from 1 June 2022. Resale price maintenance, including indirect forms, remains a serious restriction. The CMA has been one of Europe's most active enforcers — Fender at 4.5m pounds, Roland and Korg at 5.5m combined, Casio at 3.7m — and has increased fines where senior management were complicit despite compliance training. The Digital Markets, Competition and Consumers Act 2024 raises penalties to ten per cent of global turnover.

Ten dimensions on which the two regimes give genuinely different answers to the same commercial question.

Verdict colours follow the data palette: green lawful, amber conditional, red unlawful. Full citations and the state-by-state divergence are in the printable paper.

United States: policy discipline, then trademark

A defensible programme rests on an evidentiary record proving unilateral, non-negotiated, uniform administration. Route all policy communication through one designated administrator, usually outside sales. Forbid staff from discussing violations, warnings or reinstatement terms. Apply identical consequences to every violator, tracked in a documented log. Use graduated but pre-set consequences, and never reinstate on a promise.

MAP alone does not control who sells your product. The real backbone is an authorised-reseller programme: a written agreement with your direct customers controlling who may resell, imposing quality-control and channel obligations, prohibiting sales to unauthorised resellers, and requiring cooperation with anti-diversion measures. That lets you attack the source of grey-market supply rather than chase symptoms downstream.

Marketplaces do not enforce MAP. Their tools address counterfeit, intellectual property and materially different goods — not price. Filing IP complaints against mere MAP violators can breach marketplace policy and jeopardise your own brand-registry standing.

Trademark law does the heavy lifting. The first-sale doctrine generally lets a lawful purchaser resell genuine goods, and in copyright it extends to goods lawfully made abroad, making copyright weak for anti-diversion. Trademark is stronger because of two exceptions. The material-difference exception bites where goods differ from those authorised — a low threshold, no more than a slight difference which consumers would likely deem relevant, per Zino Davidoff SA v. CVS Corp. The quality-control exception applies where goods are sold outside legitimate quality controls.

What makes a quality-control programme legitimate rather than pretextual is that it is substantial, enforced consistently against all channels rather than only against discounters, and genuinely related to product quality. A warranty limited to authorised sellers must not be denied solely because a seller is unauthorised.

European Union: selective distribution, and who you supply

The lawful backbone is a selective distribution system. Under the Metro criteria a purely qualitative system falls outside Article 101(1) where the nature of the product requires it, resellers are chosen on objective qualitative criteria laid down uniformly and applied without discrimination, and the criteria go no further than necessary. Coty Germany v. Parfumerie Akzente confirmed that a supplier of luxury goods may prohibit authorised distributors from selling via discernible third-party platforms, and that such a clause is not a hardcore restriction.

Note the limit established after Rolex: an outright ban on all online sales is generally unlawful even for luxury goods. The lawful control is a platform or quality restriction, not a blanket internet ban.

Trademark rights are exhausted once goods are put on the EEA market with the proprietor's consent, so intra-EEA parallel trade generally cannot be blocked. Article 15(2) preserves a legitimate-reasons exception where the goods' condition is impaired or their presentation damages the mark's reputation, as in Copad v Christian Dior. The limits are real: exhaustion is the rule, and the exception is narrow, fact-specific and strongest for genuine luxury goods inside a coherent selective system.

So the EU levers are structural rather than price-based, and there are four of them.

1. Decide who is authorised to sell you, and on what standards — presentation, service level, minimum stock, trained support, quality standards for online sales.
2. Publish an authorised-seller list so shoppers can identify legitimate channels.
3. Enforce the qualitative criteria, consistently and without discrimination, against every member of the network.
4. Use the monitoring record for visibility, unauthorised-seller detection and grey-market evidence — never to sanction a reseller's price.

The EU do-not list

Drawn directly from paragraph 187 and from the fined fact patterns, these are the practices that convert a monitoring programme into an infringement.

• Setting or enforcing minimum or fixed resale prices, or advertised-price floors.
• Capping the maximum discount a reseller may offer, dictating sale periods, or prohibiting discounting.
• Issuing threats, warnings or penalties tied to price.
• Delaying, reducing or suspending deliveries, or terminating, in response to low pricing.
• Offering compensation, rebates or promotional reimbursement conditioned on price compliance.
• Linking a reseller's price to competitors' prices.
• Using monitoring or repricing software to pressure resellers on price. The tool is fine; the coercion is not.

Applying a single US-style MAP policy to EU distributors is a material exposure. If the policy is embedded in or referenced by EU distribution contracts, or if EU sales staff enforce it through warnings, incentives or supply consequences, the brand has created textbook indirect resale price maintenance across the EEA — precisely the fact pattern fined in 2018 and again in 2025.

Even an ostensibly unilateral MAP communication can, in the EU, become evidence of an agreement or concerted practice once distributors acquiesce and the supplier monitors and reacts. The safe course is to strip all price terms from EU-facing documents entirely.

1. Geo-scope every document. A unilateral MAP policy for the US, careful and unenforced recommended prices in the UK, and for the EU a selective-distribution agreement with no price terms at all.
2. Separate the contract terms. US authorised-dealer agreements controlling resale, channel and anti-diversion; EU selective-distribution criteria covering presentation, service, authorised listing and online quality standards.
3. Capture the record. Per listing over time: seller identity, buy-box holder, price, price reference, timestamps, retailer and full change history.
4. Split the workflow. In the US, single-point-of-contact notification with uniform graduated consequences and a documented log. In the EU, non-price compliance review only, with price data used for visibility and unauthorised-seller action.
5. Escalate correctly. In the US, an IP cease-and-desist plus contract enforcement against the leaking distributor. In the EU, selective-distribution enforcement and Article 15(2) trademark action where reputational damage or altered goods exist.

Metrics worth tracking

Violation rate, as the share of listings or sellers below policy or unauthorised. Time to resolution, from detection to correction or removal. Repeat-violator count. Price dispersion, as the spread around your reference. Buy-box hold rate, as the share of time the authorised offer holds the featured position. Unauthorised-seller count over time.

Where Merqi fits

Every programme above runs on a record of what the shelf actually did: who is selling your products, who holds the buy box, at what price, and where you are not listed at all — captured daily, per market, per retailer, and exportable with your own filters applied. That record is what a US programme needs to prove uniform administration, and what an EU programme needs in order to police the system rather than the price.

This paper is general information and does not constitute legal advice. Competition and trademark law in this area is fact-dependent and, in several respects — notably US state law and the EU efficiency defence for MAP — genuinely unsettled.
