A pharmaceutical distributor in Germany sources branded medicines through a third-party wholesaler in Romania and ships them into Portugal at a significant discount to local list prices. The Portuguese trademark holder moves to block the imports. The distributor argues that the rights were exhausted the moment the goods entered EU commerce. Both positions have solid legal grounding – and the outcome depends on a chain of doctrinal and factual questions that Portuguese and European courts have been working through for decades.
Parallel import and IP rights exhaustion in Portugal are governed by the principle of EU-wide exhaustion. Under which an intellectual property rights holder loses the right to prevent further distribution of goods it has placed on the market anywhere within the European Economic Area. The key conditions are that the goods were placed on the market by or with the consent of the rights holder. Additionally. That no legitimate reasons. such as quality alteration or repackaging damage – justify a restriction. Portuguese courts apply this doctrine consistently with EU law, but significant nuance arises in consent disputes, repackaging cases, and situations touching on goods originating outside the EEA.
This analysis covers the doctrinal foundation of exhaustion in Portuguese and EU law, competing court interpretations, the gap between the formal legal position and daily practice. Cross-border implications for businesses operating across Europe. Additionally, the strategic choices available to rights holders and importers alike.
The doctrinal foundation: exhaustion as a limit on IP rights
Intellectual property rights grant their holder an exclusive position: the right to prevent others from using, selling, or distributing the protected object without authorisation. Exhaustion doctrine is the counterweight. It reflects the policy judgment that once a rights holder has received the economic reward from a first authorised sale, the IP right should not extend to controlling every subsequent transaction in that product.
Portugal operates within the EU exhaustion regime. This means exhaustion is regional, not global. Goods placed on the market within the European Economic Area. whether in Portugal, Germany, Poland. Alternatively. Any other EEA state. by the rights holder or with its consent trigger exhaustion of the IP right in respect of those specific goods. The rights holder cannot then use IP law to block their free movement within the EEA.
Goods originating outside the EEA are treated differently. A rights holder may, under Portuguese and EU intellectual property legislation, oppose the importation of genuine goods that were first placed on the market outside the EEA. This is the boundary between parallel import and what is sometimes called grey market importation. The distinction matters enormously. A parallel importer sourcing goods from within the EEA operates under the protection of exhaustion. One sourcing from the United States, Japan, or Brazil does not, unless the rights holder has consented to EEA distribution.
Portuguese intellectual property legislation implements EU directives on trademarks, copyright, and design rights consistently. The Supremo Tribunal de Justiça (Supreme Court of Portugal) has confirmed on multiple occasions that the exhaustion principle applies to trademarks, design rights, and related rights. The courts look first to EU law and then to national implementing rules. Where EU law is determinative, domestic rules must comply.
The Nice classification system is relevant here because trademark registration – and the scope of the right being exhausted – depends on the specific goods and services registered. A trademark application covers defined categories under the Nice classification system. Exhaustion operates within those categories. A rights holder whose trademark is registered for pharmaceutical products in Nice class 5 cannot rely on a registration in class 3 to block parallel imports of the class-5 goods.
Consent: the most contested question in Portuguese exhaustion cases
The consent requirement sits at the heart of almost every contested parallel import case. Exhaustion applies only if the goods were placed on the market by or with the consent of the rights holder. The burden of proving that the rights holder consented to EEA marketing lies, in principle, with the party relying on exhaustion – the parallel importer.
However, the Tribunal da Relação (Portuguese Court of Appeal) has refined this rule in a direction more favourable to parallel importers. Where disclosure of the distribution chain would expose commercially sensitive information. such as the identity of a parallel importer's supplier within the EEA. courts have recognised that strict application of the burden of proof may be disproportionate. In those circumstances, the burden can shift to the rights holder to demonstrate that consent was not given.
This burden-shifting approach reflects European Court of Justice guidance and has been applied by Portuguese appellate courts without significant deviation. In practice, it means that a parallel importer who can demonstrate that the goods entered the EEA legitimately. through customs documentation, invoices, or traceability data – places the rights holder in a difficult evidential position. The rights holder must then show either that the goods were placed on the market outside the EEA. Alternatively. That they were placed within the EEA but subject to contractual restrictions that do not constitute consent to free circulation.
The concept of contractual restrictions on consent is a well-developed area of dispute. A rights holder who sells goods to a distributor in France subject to a territorial restriction. prohibiting resale outside France. does not thereby place those goods on the EEA market with consent to free EEA circulation. But the validity of that restriction as a defence against exhaustion is limited. The restriction binds the French distributor in contract. However. Whether it negates exhaustion as against a downstream purchaser who had no knowledge of the restriction is a question on which courts in Portugal and across the EU have not always agreed.
The dominant position, consistent with European Court of Justice authority. Is that a contractual restriction does not prevent exhaustion from arising if the goods were in fact placed within the EEA with the rights holder's knowledge and economic benefit. The practical consequence for brand owners is that distribution contracts must be drafted with precision. Ambiguous territorial provisions create the very consent ambiguity that parallel importers exploit. Businesses seeking rigorous IP protection across their European distribution networks should consider how their contractual architecture interacts with exhaustion doctrine – a matter where experienced intellectual property counsel in Portugal can provide significant strategic value.
Repackaging and relabelling: where exhaustion meets product integrity
Pharmaceutical parallel imports routinely involve repackaging. A medicine approved in Germany and sold in Portuguese-labelled packaging requires new outer cartons, Portuguese-language package inserts, and sometimes a new barcode. The rights holder objects that repackaging infringes its trademark. The parallel importer argues that the repackaging is necessary for market access and that exhaustion prevents the trademark from being used as a barrier.
Portuguese courts apply the conditions developed by EU case law with precision. The right to object to repackaging survives exhaustion only where specific cumulative conditions are met. First, the repackaging must genuinely be necessary to market the product in Portugal – not merely commercially convenient. Second, the repackaging must not affect the original condition of the product or mislead the consumer. Third, the repackaged product must clearly indicate the repackager's identity and the manufacturer's name. Fourth, the parallel importer must notify the trademark holder in advance – typically at least several weeks before the product enters the market.
The advance notification requirement is one of the most common practical failure points. Parallel importers who skip or delay this step lose the benefit of EU law's repackaging tolerance even if all other conditions are satisfied. Portuguese courts treat this as a genuine procedural obligation, not a formality. A rights holder who can demonstrate that no advance notice was given may succeed in an infringement claim regardless of the exhaustion argument.
The condition that the product's original condition must not be affected is also litigated frequently. Where a parallel importer opens the original packaging to substitute inserts, adds stickers over original barcodes, or exposes the product to conditions that affect its integrity, the rights holder's objection to repackaging becomes stronger. Pharmaceutical products are particularly sensitive here because storage and handling conditions affect both safety and the strength of the manufacturer's position.
Design rights and copyright present similar but not identical analysis. Repackaging that reproduces protected artwork – even where the trademark argument fails – may give rise to a copyright or design infringement claim. Rights holders operating in Portugal should assess all available IP rights when building an anti-parallel-import strategy, rather than relying exclusively on trademark law.
Outside the EEA: the hard boundary and its strategic implications
The EU exhaustion regime creates a sharp divide. Goods placed on the market in the United States, Brazil, Switzerland, or the United Kingdom since 2021 are not subject to EU exhaustion rules. A rights holder can use Portuguese and EU intellectual property legislation to block their importation. This applies to trademark-protected goods, copyright-protected works, and design-protected products alike.
Switzerland deserves specific mention. Despite its geographic position and close economic ties with the EU, Switzerland is not part of the EEA. Goods placed on the Swiss market are not exhausted for EEA purposes. This is a frequent source of error for international businesses that assume a product sold in Geneva is freely distributable in Lisbon. The assumption is incorrect.
The United Kingdom presents a post-Brexit complication. Goods placed on the UK market before 31 December 2020 when the UK was an EU member state may be treated differently from goods placed on the UK market after that date. Portuguese courts and EU institutions have addressed this transition carefully, and the current position is that post-Brexit UK market placement does not trigger EU exhaustion. For businesses with UK-Portugal distribution structures, this is a material change that requires active review of existing agreements.
Cross-border enforcement in Portugal relies on civil procedure rules. A rights holder seeking to block non-EEA parallel imports can apply for a preliminary injunction under civil procedure rules, seek a customs seizure order, or initiate an infringement action. Each route has a different speed, cost, and evidentiary threshold. Preliminary injunctions are available where the rights holder can demonstrate a prima facie infringement and an urgency that prevents waiting for a full trial. Customs intervention requires prior recordal with the Portuguese customs authority and the EU-level equivalent. An infringement claim at the merits stage involves full documentary disclosure and can take several years to resolve at first instance.
The interaction between IP enforcement and the Portuguese tax and regulatory system adds complexity. The CAAD – Centro de Arbitragem Administrativa e Fiscal (Administrative and Tax Arbitration Centre) – handles administrative disputes but not civil IP claims. Tax issues arising from parallel import transactions – transfer pricing, customs valuation, VAT on relabelling services – are separate from the IP analysis but must be managed in parallel. International businesses would benefit from coordinating their IP and tax strategies, a point that connects naturally to the firm's broader work in technology-adjacent legal matters in Portugal.
Gap between formal legal position and daily commercial practice
The formal legal position on exhaustion is relatively settled in Portugal. The gap between statute and practice is wider than it appears from reading court decisions.
First, many parallel import disputes never reach the courts. Rights holders issue cease-and-desist letters; parallel importers either comply or negotiate. The confidential resolution of these disputes means that the body of published case law underrepresents the frequency and commercial significance of parallel import activity in Portugal.
Second, IP registration quality varies. A rights holder whose trademark registration has gaps – missing goods, ambiguous Nice classification, or lapses in renewal – faces a more difficult infringement claim even where the exhaustion point is in its favour. Portuguese courts have dismissed infringement actions where the claimed trademark did not clearly cover the goods in dispute. This is a structural weakness that can be avoided entirely with proper portfolio management.
Third, opposition proceedings at the trademark registration stage are separate from exhaustion disputes but interact with them. A business that successfully opposes a parallel importer's attempt to register a variant of its brand in Portugal has strengthened its enforcement position in any subsequent parallel import dispute. Conversely, a rights holder that has failed to oppose an importer's registration faces a more contested enforcement environment.
Fourth, enforcement in Portugal requires engagement with both the Instituto Nacional da Propriedade Industrial – INPI (National Industrial Property Institute of Portugal) – for administrative matters and the civil courts for litigation. The INPI does not adjudicate infringement disputes. It handles registration, opposition, and cancellation proceedings. Parallel import disputes are resolved in the civil courts, with the Tribunal da Relação available on appeal and the Supreme Court of Portugal as the final instance on points of law.
Fifth, Portuguese corporate legislation (CSC) – the Código das Sociedades Comerciais – is relevant where parallel import activity is conducted through a Portuguese entity. Questions of director liability, corporate liability for IP infringement, and the ability to pierce corporate structures to reach assets are governed by corporate legislation alongside IP legislation. An importer operating through a thin-capitalised Portuguese subsidiary may face enforcement obstacles even where the IP infringement is established.
For a business accustomed to common law precedent systems, the Portuguese civil law approach to IP exhaustion may feel less predictable. Cases are decided on doctrinal analysis rather than fact-pattern matching to prior decisions. The Supreme Court of Portugal's guidance is authoritative but not binding in the way that English Court of Appeal judgments bind lower courts. Practitioners in Portugal note that this creates genuine divergence between district courts on procedural and evidentiary questions, even where the substantive legal analysis is consistent.
Strategic recommendations for rights holders and parallel importers
The strategic landscape for rights holders and parallel importers is not symmetric. Rights holders have more tools but face higher costs of enforcement. Parallel importers have the protection of the single market principle but carry evidentiary and compliance obligations that many underestimate.
For rights holders, the priority is building a defensible IP portfolio and a distribution architecture that minimises consent ambiguity. This means ensuring that trademark applications cover all relevant Nice classification categories, that registrations are current, and that distribution contracts include clear territorial provisions. It also means maintaining records of where goods are first placed on the market – documentation that will be critical in any future exhaustion dispute.
A rights holder considering opposition proceedings against a parallel importer's trademark application should act promptly. Opposition windows are time-limited. Missing a filing deadline ends the opposition route without prejudice to infringement claims, but weakens the overall enforcement position.
Monitoring customs channels is equally important. Customs recordal of IP rights with Portuguese and EU customs authorities enables seizure of infringing goods at the border before they enter the distribution chain. This is a preventive measure with significantly lower cost than post-distribution litigation.
For parallel importers, the primary risk is inadequate documentation of the supply chain. A parallel importer who cannot trace the EEA provenance of its goods faces an infringement claim it may not be able to defend. Robust procurement documentation – invoices, customs declarations, certificates of origin – is essential. Where repackaging is involved, compliance with notification and labelling requirements is not optional. The advance notification obligation must be treated as a hard deadline, not an administrative courtesy.
For importers operating across multiple European markets, Portugal's membership in the EU means that a strategy validated in one jurisdiction generally transfers. But practical differences in court culture, enforcement speed, and customs cooperation mean that a Portugal-specific assessment remains necessary. Lawyers in Portugal with cross-border IP experience can assess whether a distribution model that works in France will hold up under Portuguese enforcement conditions.

The outlook for exhaustion doctrine in Portugal reflects broader EU trends. Digital goods present the sharpest new challenge. The exhaustion principle as developed in case law was designed for physical goods. Software licences, digital downloads, and streaming rights do not transfer in the same way as physical products. Portuguese courts applying EU intellectual property legislation have held that digital exhaustion is more limited than physical exhaustion. A business that purchases a software licence in one EU country cannot, under current doctrine, resell that licence in Portugal on the same basis as it could resell a physical product.
Emerging questions in the digital domain also connect to AI-generated content and the training data used in AI systems. The intersection of exhaustion doctrine with AI-related rights is undeveloped in Portugal and across the EU. Where AI systems are trained on copyright-protected works, questions of first-sale doctrine and exhaustion may become relevant to licensing strategies. The evolving regulatory treatment of AI and related rights creates forward-looking considerations for businesses building IP portfolios today, a dimension explored further in comparative analysis of parallel import rules in Spain.
Trade mark exhaustion in the context of luxury goods also continues to generate case law. Rights holders in the luxury sector have sought to maintain quality-control arguments as a basis for resisting parallel imports even where the goods originated within the EEA. Portuguese courts have been cautious about accepting quality-control arguments where the products have not been demonstrably altered. The doctrine of legitimate reasons to oppose further commercialisation – which survives exhaustion – is narrowly construed. Courts look for material damage to the trademark's reputation, not merely a commercial preference for exclusive distribution.
The interface between exhaustion and competition law adds a further dimension. A rights holder that systematically uses IP enforcement to partition the single market may face challenge under EU competition legislation. Portuguese competition law enforcement authorities can refer findings to the European Commission. A brand owner that pursues parallel import actions across multiple EEA jurisdictions in a coordinated way may find that the IP defence becomes a competition law liability. This risk does not negate the right to enforce IP, but it demands proportionality in strategy.
Frequently asked questions
Q: A supplier outside the EU has sent our branded goods to a Portuguese distributor without our authorisation. Can we stop the distribution?
A: Yes, provided the goods were first placed on the market outside the EEA without your consent to EEA distribution. Under EU exhaustion rules, non-EEA market placement does not exhaust your IP rights in Portugal. You can seek a preliminary injunction from a Portuguese civil court, apply for customs seizure, or initiate a full infringement claim. Acting quickly is important because the injunction standard requires showing urgency alongside a prima facie infringement.
Q: How long does a parallel import infringement case typically take in Portugal, and what costs should we anticipate?
A: A first-instance civil court decision on the merits can take between two and four years in Portugal, depending on the court's docket and the complexity of the evidentiary phase. Preliminary injunction proceedings can yield a ruling within weeks. Legal costs in significant IP disputes typically run into the thousands of euros at each stage, and enforcement costs should be weighed against the commercial value of the distribution affected. A preliminary injunction, if granted, can provide substantial relief while the main case proceeds.
Q: Is it a common misconception that repackaging always infringes a trademark in a parallel import context?
A: Yes. Repackaging in the context of EEA parallel imports does not automatically infringe a trademark. EU law and Portuguese courts recognise that repackaging may be necessary to access the Portuguese market. Additionally, that it is permissible if strict conditions are met: the repackaging must be necessary. Must not affect the original condition of the goods, must identify the repackager. Additionally, the trademark holder must receive advance notice. Failure to meet any one of these conditions restores the right to object – but the right is not absolute in the first place. Engaging a lawyer in Portugal with cross-border IP experience early in the process significantly reduces the risk of falling foul of the notification requirements.
