When it comes to trademarks, it’s not the first to speak who wins, it’s the first to file. Apple has fully grasped this.
A filing on the very day of the announcement
On September 9, Apple unveiled its iPhone Duo.
What went less noticed: a US trademark application was filed the very same day.
Nothing unusual at first glance — but a closer look at this filing shows that it claims priority from an application filed in Liechtenstein on March 12, 2026, just three days before the six-month priority deadline expired.
In other words: at the very moment the name becomes public, it has already been protected for nearly six months.
The mechanism: Article 4 of the Paris Convention
The Paris Union right of priority gives an applicant a six-month period, running from their first filing, to extend protection to other States of the Paris Union while retaining the date of the original filing.
In practical terms, the September 9 US application benefits from the March 12 date, thereby neutralizing any third-party filings made in the interim.
One difficulty remains, and this is where the strategy comes in: in most jurisdictions, a trademark application is published — and therefore searchable — a few days or weeks after filing, and can quickly be spotted by legal practitioners, specialist journalists or competitors.
Without an adapted strategy, filing six months ahead amounts to revealing the project six months before its official announcement, hence the importance of choosing the right jurisdiction for the first filing.
Why Liechtenstein?
This is no improvisation.
Apple has long used jurisdictions whose registers are not immediately accessible — Jamaica and Liechtenstein are among its documented waypoints since at least 2017, precisely to sidestep this risk.
The sequence is always the same:
— File in a Paris Union member State whose register does not publish immediately;
— Let the six-month window run during the final development phase;
— File in the target jurisdictions on the day of the announcement, claiming priority.
The benefit is threefold:
— A priority right enforceable against third parties, retroactive to the date of the first filing;
— The neutralization of any competing filing made in the interim;
— Confidentiality maintained until the big day.
Where a conventional filing forces a trade-off between early protection and project secrecy, this construction removes that sometimes difficult choice.
Monaco opens exactly the same window
The Monegasque register shares this same defining feature: a trademark is not published until after it has been registered, more precisely, within the following few months.
A Monegasque filing could therefore have played the role of the Liechtenstein filing here: serving as a confidential first filing and as the basis for a later priority claim, without a premature and uncontrolled disclosure of the project.
As Monaco is party to the Paris Convention, this filing is open to any applicant and gives rise to a right of priority across all States of the Union (181 States).
For whom does Monaco become a true filing hub?
This is where the Principality distinguishes itself from a mere waypoint. Monaco is also party to the Madrid System, which allows a Monegasque trademark to serve not only as a priority basis, but also as the basic mark for an international registration application.
This second dimension requires a genuine connection to the Principality.
Under Article 2(1) of the Madrid Protocol, the applicant must be a national of the contracting State, be domiciled there, or have “a real and effective industrial or commercial establishment” there — the same wording used in Article 3 of the Paris Convention, which refers to “real and effective industrial or commercial establishments”.
A purely nominal presence is therefore not enough: genuine economic activity is required, even though this is not always thoroughly or systematically verified by the Offices.
For Monegasque nationals, individuals domiciled in the Principality, and foreign companies with such an establishment there, Monaco can thus become the starting point of a global strategy: a confidential first filing, six months of priority, and a basic mark enabling international expansion via the Madrid System — all from a single office, in French, and at controlled cost.
In other words: where Apple had to engineer a detour through a third jurisdiction, a company established in Monaco has this window of confidentiality directly within the Principality, before moving on to its international rollout.
A five-year dependency period: the appointment not to miss
The link between the original trademark and its international extension is not permanent. For five years from the date of the international registration, it remains dependent on the basic mark.
If the original trademark is withdrawn, removed, refused or cancelled during this period — or as the outcome of an action brought during it — the international registration falls to the same extent in the designated countries (Art. 6(2) and 6(3) of the Protocol). This is known as the central attack mechanism.
A safety net exists: Article 9quinquies allows the cancelled international registration to be transformed into national or regional applications that retain its filing date, provided action is taken within three months of the cancellation.
After the five years have passed, the international registration becomes autonomous: the original trademark can disappear without taking its international extension down with it.
The fate of the original trademark can therefore be reassessed at the end of the fifth year. Depending on the actual use made of the sign in the Principality and the value of keeping a title there, its continuation then becomes a matter of weighing cost against usefulness.
During these first five years, however, the basic mark remains the structure’s point of vulnerability.
This is a risk that can be limited upfront through prior-rights searches and through the specific features of Monaco’s legal and judicial framework.
A particularly robust basic mark
Not all jurisdictions are equal when it comes to carrying five years of dependency.
Three features make the Monegasque filing markedly less exposed than its equivalents at major offices:
A less crowded register. The number of earlier registered rights there is nowhere near that of the European Union or the United States. The likelihood of colliding with an earlier right — and therefore the risk of challenge — is mechanically reduced, as are the cost and duration of prior-rights searches.
The absence of an opposition procedure. No third party can administratively block registration. Where a European or US filing opens a window during which any vigilant rights holder can step in at low cost, a Monegasque filing proceeds straight to registration without this stage. A third party wishing to challenge it must go through the courts — a considerably higher threshold of commitment, cost and time.
The absence of a use requirement. Maintaining the title is not conditional on genuine use in the Principality. The original trademark can therefore endure — and continue to carry the international registration throughout the dependency period — without the applicant having to show local use.
The Monegasque filing is therefore not merely discreet: it is a basic mark that is structurally difficult to attack, which correspondingly reduces exposure to central attack during the five critical years.
Discretion going in, resilience throughout the dependency period, freedom to decide on the way out.
Points of caution
The mechanism is effective, but formalistic. Four points determine its validity:
— The first filing must truly be the first. Priority can only be claimed on the basis of the earliest filing, wherever it was made. A forgotten earlier filing undermines the whole construction.
— The six-month deadline is a strict deadline, counted from date to date and to be planned into the project’s timeline.
— Priority covers only what was filed. Identity of the sign, matching goods and services: anything not included in the first filing does not benefit from its date.
— What later becomes of the first filing is irrelevant. A properly made filing gives rise to a right of priority even if it is subsequently withdrawn or abandoned (Art. 4.A(3) of the Paris Convention). The first filing can therefore be no more than a dating tool.
What this changes for you
This strategy is not reserved for global-scale launches.
Any company preparing a product launch, a rebrand, an external growth transaction or a new range is exposed to the same risk: the filing itself gives the project away.
The question is therefore not only where to protect, but in what order and from what date.
As a result, forward planning makes it possible to preserve a project’s confidentiality while securing its priority date ahead of its official announcement.
And for those connected to the Principality, the answer often starts here.
