Design protection and product copying: step by step starts with confirming which right actually covers the product, then documenting the copy, sending a formal warning and choosing between customs action, an interim injunction or full infringement proceedings before the Patent and Market Court. Skipping a step narrows the options left at trial.
Who this concerns
This procedure applies to any business that holds, or believes it holds, a design right in Sweden or across the EU and finds a competitor's product looking closer to its own than coincidence allows. It applies equally to a Swedish manufacturer whose furniture line has been mirrored by a supplier in another EU state, and to a foreign brand owner who registered a Community design and now sees an identical product for sale on a Swedish marketplace. The intellectual property and UPC practice at Lodline works on both directions.
It does not apply to disputes about trademarks, patents or trade secrets, even where the same product triggers all three. Those disputes run on separate procedural tracks with their own deadlines, and treating a design claim and a trademark claim as interchangeable is one of the more common ways a strong case gets diluted before it reaches court.
What the law says
Two protection routes sit alongside each other. A national design right, granted by PRV (Patent- och registreringsverket, the Swedish Patent and Registration Office), covers Sweden alone. The Registered Community Design and the Unregistered Community Design, both administered by EUIPO, cover the whole EU from a single filing or from first disclosure. Under Swedish law as it currently stands, both regimes protect a design only if it is new and has individual character at the relevant date, and both let the right holder stop a third party from making, offering, marketing, importing, exporting or stocking a product that fails to produce a different overall impression on an informed user.
Copyright can run alongside a registered design where the same appearance also qualifies as a work of applied art, but that overlap is assessed independently. Registration is not a substitute for meeting the copyright threshold, and a company that assumes otherwise sometimes discovers the gap only once litigation has already started.
The practical consequence is that the choice of right to rely on, and the choice of forum, is made before the first letter is drafted, not worked out afterwards.
How it works in practice
Confirm what right actually covers the product
The starting point is not the product on the shelf, it is the registration certificate, or the disclosure evidence if no registration exists. Pull the actual filing, check which views were submitted, and compare those views, not a marketing photo, against the copy. A design registered for a chair frame does not automatically cover the upholstery pattern applied to it later, and a claim built on the wrong scope collapses at the first serious challenge.
Fix the disclosure and priority timeline
Establish, with dated evidence, when the design was first shown to the public and when any application was filed. This timeline decides which protection exists at all, whether a competitor's own prior use can be raised as a defence, and whether the unregistered route is still open. Internal design files, supplier correspondence and trade fair records are the usual sources, and they need to be gathered before memory of the sequence fades.
Build the evidence file on the copying product
Buy the competing product through a normal commercial channel, keep the receipt, photograph it against the registered design views side by side, and record where and from whom it was obtained. A comparison built after a formal complaint has already been sent is weaker than one built before, because the other side can argue the product changed in the meantime.
Choose the enforcement track
There are three realistic tracks: a customs recordal that stops infringing goods at the border, an application for an interim injunction that stops sales while the underlying dispute is decided, and full infringement proceedings on the merits. They are not mutually exclusive, but the order in which they are used changes what evidence is available later, and a customs seizure obtained too early, before the comparison file is solid, can be challenged and released.
Send a formal warning letter
The letter sets out the right relied on, the specific product compared against specific registered views, and a deadline for a substantive response, not a courtesy acknowledgement. It also fixes, for later use in court, the date from which the other side can no longer claim innocent infringement.
File a customs application where goods cross a border
Where the copying product is manufactured or shipped from outside Sweden, an application for customs action against infringing goods lets Swedish customs detain a shipment at the border before it reaches the market, provided the registration and the comparison evidence are already in order when the application is filed. This route only works ahead of a shipment; it does not reach stock already inside the country.
Apply for an interim injunction
Where the copy is already on sale and the harm is accumulating, an application to the Patent and Market Court (Patent- och marknadsdomstolen) for an interim injunction can stop further sales pending a decision on the merits. The court weighs the strength of the design right, the likelihood of infringement, and the balance of harm if it acts too soon or too late. A weak evidence file at this stage is rarely repaired later.
Bring full infringement proceedings
If the warning letter produces no acceptable undertaking, the claim proceeds to full proceedings before the Patent and Market Court, seeking a final injunction, damages, and, depending on the facts, destruction or recall of the infringing stock. This is the stage at which the documentation gathered in the earlier steps either carries the case or exposes its gaps.
Enforce the outcome
A judgment or a settlement is only as useful as the enforcement behind it. Where the infringing party's assets or manufacturing sit outside Sweden, enforcement usually means recognising and executing the decision in another jurisdiction, and that step has its own procedural requirements separate from the original claim.
What to check before sending the first letter:
- Which specific registration or disclosure the claim actually rests on, and whether it has lapsed for non-renewal.
- Whether the compared views match the alleged copy in scope, not just in general appearance.
- Whether the copying party's manufacturing, warehousing or corporate seat sits inside or outside Sweden, because that changes which enforcement route is realistic.
- Whether a customs recordal is worth filing before the warning letter goes out, given how the goods reach the market.
- Whether the same product also raises a trademark or trade secret issue that needs a separate, parallel track.
When the copying manufacturer, its distributor, or its parent company is based outside Sweden, the sequence does not change in substance, but two things do. First, a Swedish judgment against a company with no assets or presence in Sweden is only useful once it is recognised where the assets actually are, and that recognition step should be scoped before litigation starts, not after judgment is obtained. Second, evidence of manufacture abroad, such as supplier contracts or shipping records, often sits with a third party outside Swedish jurisdiction, and gathering it can require separate cooperation requests that add their own timeline to the case.
Common questions in this procedure
What happens if the copied product is only sold through a marketplace and not directly by the manufacturer?
The marketplace operator is not usually the right target for a design claim on its own, but it can be required to remove listings once notified, and the underlying seller remains the primary respondent. Evidence should still identify the actual seller behind the listing, because a takedown without a warning to the seller rarely stops the same product reappearing under a different listing.
Can a design claim proceed if the registration has not yet been renewed for the current period?
No. A design right that has lapsed for non-renewal offers nothing to enforce, regardless of how clear the copying looks. Checking renewal status is the first item on the list above precisely because it is the fastest way a case is lost before it starts.
Is a cease-and-desist letter a legal requirement before going to court?
It is not a formal precondition, but skipping it removes the clearest evidence that the other side knew about the right and continued regardless, which affects both the strength of an interim injunction application and the calculation of damages later.
The numbers
Every deadline in this sequence is set by the forum handling it rather than by a fixed calendar that applies across the board. A warning letter's response deadline is set by the sender and should be short enough to preserve urgency for a later injunction application, but long enough to survive a challenge that it was unreasonable. How quickly a customs recordal becomes active depends on how the application is documented and on the customs authority's own processing queue at the time it is filed, not on a figure that can be quoted in advance. The same is true of how quickly the Patent and Market Court schedules an interim injunction hearing: it depends on the court's current caseload and on how complete the application is when it is lodged, and a case with a thin evidence file typically loses time to requests for further material rather than gaining a faster hearing.
Where a specific renewal date, filing period or statutory time limit applies to a particular registration, that date comes from the registration certificate itself, not from a general rule that can be stated for every design right at once.
Where it usually goes wrong
The most common failure is treating the marketing photograph as the scope of protection instead of the actual filed views, which produces a comparison that looks compelling internally and falls apart the moment the other side points to the registration document. Close behind it is sending a warning letter before the evidence file on the copy is complete, which locks in a position that has to be walked back once better evidence surfaces.
A second cluster of failures sits around timing. Waiting for a full damages calculation before applying for an interim injunction usually means the injunction arrives after the sales season that mattered has already passed. Filing a customs application after a shipment has cleared the border achieves nothing, because the mechanism only reaches goods still in transit or in customs custody.
A third failure is specific to cross-border cases: obtaining a Swedish judgment against a copying party with no Swedish assets and only then asking whether it can be enforced anywhere. That question belongs at the start of the sequence, when the choice of forum and the choice of enforcement route are still open, not at the end when the only options left are the ones nobody scoped in advance.
Finally, where the same product also looks like a trademark or trade secret problem, running only the design claim and ignoring the rest sometimes closes doors that would have stayed open if all three tracks had been assessed together at the outset.
What to do next
This sequence takes a company from noticing a copy to a completed enforcement action, but each step above depends on evidence and documents specific to the actual product and the actual registration, which is exactly the point where a self-run comparison stops being reliable. The natural next step is to book a preliminary assessment, which looks at the registration scope, the comparison evidence and the realistic enforcement route before any letter goes out.
