Disputed PDOs: the name is debated, the proof on the product remains
Behind every wheel
European protected designations could become «common names» in laws such as the «Farm Act» and the «Safety Bill».
Exteryo Report editorial staff
Let's see where the origin of a Parmigiano or an Asiago can be proven on the product, along the supply chain.
The short answer
The origin is proven by what accompanies the physical product:
- Identityan identifier linked to the single wheel or package
- Tracethe supply chain history recorded step by step
- Proofcertified documents and tracked accesses
The short answer
This way, buyers can check the origin, in addition to reading it on the label.
Why it's not simple
The obvious answer: the law is enough to protect the name.
There's more.
Why it's not simple
The source reports that American laws and the position of the Wipo director general treat names like Asiago and Gorgonzola as unprotected, while European law says the opposite. As long as the name is debated in different venues, what remains verifiable everywhere is the proof linked to the product itself.

Who can prove that a Parmigiano, an Asiago or a Gorgonzola is original?
The name and the proof
The name of a designation can be disputed in a law; the documented history of a single wheel remains a verifiable fact.
The source
According to the source, the Trump administration aims to turn European protected designations into «common names», usable by American producers also for export.
The source
The source indicates that this step is codified in the «Farm Act», already approved, and in the «Safety Bill», pending approval.
The source
On 15 October, in Rome, Wipo director general Daren Tang explained that designations like Asiago and Gorgonzola are not protected; European law and EU agreements with Mercosur say the opposite, the text writes.
Note
Wipo is the World Intellectual Property Organization, a United Nations agency.

The proofs that travel with the object remain verifiable: identity of the piece, trace of the steps, certified documents.
Before moving on
How many protected designations does Italy have, according to the source?
The source
Italy is the most exposed country, with almost nine hundred protected designations according to the source.
The wheel
For each one, serialisation, that is distinguishing every single piece from the others, allows linking a wheel to its history.

How can a consumer check the origin beyond the label?
A tap
With a tap of the smartphone on the NFC tag, the consumer opens the content linked to that package and reads its history.
A tap
With Exteryo ShowMe, contents linked to an object via NFC, a video or a guide are unlocked only by approaching the object, with no app to install.
Tap the tag
What does the tag add to the label?

What tools help a producer to prove the provenance?
Certified documents
A producer proves the provenance when their supply chain documents are serialised, tracked and certified by a third party.
Our case
In our case of document certification with tracked accesses, every document is serialised and every reading creates a unique log.
Our case
The documentation is certified by a third party: it is a model applicable to certificates of origin and breeding.
Note
Technology supports the proof; it does not replace the legal protection of the name, which remains a matter of laws and agreements.
In a sentence
The name can be debated in a law. The history of a wheel, written step by step, remains its own.
