Access by design and the user data-access and sharing rights

The core connected-product regime: accessible-by-design product and related-service data with pre-contractual information duties, the user right to access and use that data, and the user right to have it shared with a third party.

Article 3 — Obligation to make product data and related service data accessible to the user

Verbatim from EUR-Lex (Regulation (EU) 2023/2854 (Data Act) 32023R2854), via the Publications Office Cellar API.

1. Connected products shall be designed and manufactured, and related services shall be designed and provided, in such a manner that product data and related service data, including the relevant metadata necessary to interpret and use those data, are, by default, easily, securely, free of charge, in a comprehensive, structured, commonly used and machine-readable format, and, where relevant and technically feasible, directly accessible to the user.

2. Before concluding a contract for the purchase, rent or lease of a connected product, the seller, rentor or lessor, which may be the manufacturer, shall provide at least the following information to the user, in a clear and comprehensible manner:

3. Before concluding a contract for the provision of a related service, the provider of such related service shall provide at least the following information to the user, in a clear and comprehensible manner:

Article 4 — The rights and obligations of users and data holders with regard to access, use and making available product data and related service data

Verbatim from EUR-Lex (Regulation (EU) 2023/2854 (Data Act) 32023R2854), via the Publications Office Cellar API.

1. Where data cannot be directly accessed by the user from the connected product or related service, data holders shall make readily available data, as well as the relevant metadata necessary to interpret and use those data, accessible to the user without undue delay, of the same quality as is available to the data holder, easily, securely, free of charge, in a comprehensive, structured, commonly used and machine-readable format and, where relevant and technically feasible, continuously and in real-time. This shall be done on the basis of a simple request through electronic means where technically feasible.

2. Users and data holders may contractually restrict or prohibit accessing, using or further sharing data, if such processing could undermine security requirements of the connected product, as laid down by Union or national law, resulting in a serious adverse effect on the health, safety or security of natural persons. Sectoral authorities may provide users and data holders with technical expertise in that context. Where the data holder refuses to share data pursuant to this Article, it shall notify the competent authority designated pursuant to Article 37.

3. Without prejudice to the user’s right to seek redress at any stage before a court or tribunal of a Member State, the user may, in relation to any dispute with the data holder concerning the contractual restrictions or prohibitions referred to in paragraph 2:

4. Data holders shall not make the exercise of choices or rights under this Article by the user unduly difficult, including by offering choices to the user in a non-neutral manner or by subverting or impairing the autonomy, decision-making or choices of the user via the structure, design, function or manner of operation of a user digital interface or a part thereof.

5. For the purpose of verifying whether a natural or legal person qualifies as a user for the purposes of paragraph 1, a data holder shall not require that person to provide any information beyond what is necessary. Data holders shall not keep any information, in particular log data, on the user’s access to the data requested beyond what is necessary for the sound execution of the user’s access request and for the security and maintenance of the data infrastructure.

6. Trade secrets shall be preserved and shall be disclosed only where the data holder and the user take all necessary measures prior to the disclosure to preserve their confidentiality in particular regarding third parties. The data holder or, where they are not the same person, the trade secret holder shall identify the data which are protected as trade secrets, including in the relevant metadata, and shall agree with the user proportionate technical and organisational measures necessary to preserve the confidentiality of the shared data, in particular in relation to third parties, such as model contractual terms, confidentiality agreements, strict access protocols, technical standards and the application of codes of conduct.

7. Where there is no agreement on the necessary measures referred to in paragraph 6, or if the user fails to implement the measures agreed pursuant to paragraph 6 or undermines the confidentiality of the trade secrets, the data holder may withhold or, as the case may be, suspend the sharing of data identified as trade secrets. The decision of the data holder shall be duly substantiated and provided in writing to the user without undue delay. In such cases, the data holder shall notify the competent authority designated pursuant to Article 37 that it has withheld or suspended data sharing and identify which measures have not been agreed or implemented and, where relevant, which trade secrets have had their confidentiality undermined.

8. In exceptional circumstances, where the data holder who is a trade secret holder is able to demonstrate that it is highly likely to suffer serious economic damage from the disclosure of trade secrets, despite the technical and organisational measures taken by the user pursuant to paragraph 6 of this Article, that data holder may refuse on a case-by-case basis a request for access to the specific data in question. That demonstration shall be duly substantiated on the basis of objective elements, in particular the enforceability of trade secrets protection in third countries, the nature and level of confidentiality of the data requested, and the uniqueness and novelty of the connected product, and shall be provided in writing to the user without undue delay. Where the data holder refuses to share data pursuant to this paragraph, it shall notify the competent authority designated pursuant to Article 37.

9. Without prejudice to a user’s right to seek redress at any stage before a court or tribunal of a Member State, a user wishing to challenge a data holder’s decision to refuse or to withhold or suspend data sharing pursuant to paragraphs 7 and 8 may:

10. The user shall not use the data obtained pursuant to a request referred to in paragraph 1 to develop a connected product that competes with the connected product from which the data originate, nor share the data with a third party with that intent and shall not use such data to derive insights about the economic situation, assets and production methods of the manufacturer or, where applicable the data holder.

11. The user shall not use coercive means or abuse gaps in the technical infrastructure of a data holder which is designed to protect the data in order to obtain access to data.

12. Where the user is not the data subject whose personal data is requested, any personal data generated by the use of a connected product or related service shall be made available by the data holder to the user only where there is a valid legal basis for processing under Article 6 of Regulation (EU) 2016/679 and, where relevant, the conditions of Article 9 of that Regulation and of Article 5(3) of Directive 2002/58/EC are fulfilled.

13. A data holder shall only use any readily available data that is non-personal data on the basis of a contract with the user. A data holder shall not use such data to derive insights about the economic situation, assets and production methods of, or the use by, the user in any other manner that could undermine the commercial position of that user on the markets in which the user is active.

14. Data holders shall not make available non-personal product data to third parties for commercial or non-commercial purposes other than the fulfilment of their contract with the user. Where relevant, data holders shall contractually bind third parties not to further share data received from them.

Article 5 — Right of the user to share data with third parties

Verbatim from EUR-Lex (Regulation (EU) 2023/2854 (Data Act) 32023R2854), via the Publications Office Cellar API.

1. Upon request by a user, or by a party acting on behalf of a user, the data holder shall make available readily available data, as well as the relevant metadata necessary to interpret and use those data, to a third party without undue delay, of the same quality as is available to the data holder, easily, securely, free of charge to the user, in a comprehensive, structured, commonly used and machine-readable format and, where relevant and technically feasible, continuously and in real-time. The data shall be made available by the data holder to the third party in accordance with Articles 8 and 9.

2. Paragraph 1 shall not apply to readily available data in the context of the testing of new connected products, substances or processes that are not yet placed on the market unless their use by a third party is contractually permitted.

3. Any undertaking designated as a gatekeeper, pursuant to Article 3 of Regulation (EU) 2022/1925, shall not be an eligible third party under this Article and therefore shall not:

4. For the purpose of verifying whether a natural or legal person qualifies as a user or as a third party for the purposes of paragraph 1, the user or the third party shall not be required to provide any information beyond what is necessary. Data holders shall not keep any information on the third party’s access to the data requested beyond what is necessary for the sound execution of the third party’s access request and for the security and maintenance of the data infrastructure.

5. The third party shall not use coercive means or abuse gaps in the technical infrastructure of a data holder which is designed to protect the data in order to obtain access to data.

6. A data holder shall not use any readily available data to derive insights about the economic situation, assets and production methods of, or the use by, the third party in any other manner that could undermine the commercial position of the third party on the markets in which the third party is active, unless the third party has given permission to such use and has the technical possibility to easily withdraw that permission at any time.

7. Where the user is not the data subject whose personal data is requested, any personal data generated by the use of a connected product or related service shall be made available by the data holder to the third party only where there is a valid legal basis for processing under Article 6 of Regulation (EU) 2016/679 and, where relevant, the conditions of Article 9 of that Regulation and of Article 5(3) of Directive 2002/58/EC are fulfilled.

8. Any failure on the part of the data holder and the third party to agree on arrangements for transmitting the data shall not hinder, prevent or interfere with the exercise of the rights of the data subject under Regulation (EU) 2016/679 and, in particular, with the right to data portability under Article 20 of that Regulation.

9. Trade secrets shall be preserved and shall be disclosed to third parties only to the extent that such disclosure is strictly necessary to fulfil the purpose agreed between the user and the third party. The data holder or, where they are not the same person, the trade secret holder shall identify the data which are protected as trade secrets, including in the relevant metadata, and shall agree with the third party all proportionate technical and organisational measures necessary to preserve the confidentiality of the shared data, such as model contractual terms, confidentiality agreements, strict access protocols, technical standards and the application of codes of conduct.

10. Where there is no agreement on the necessary measures referred to in paragraph 9 of this Article or if the third party fails to implement the measures agreed pursuant to paragraph 9 of this Article or undermines the confidentiality of the trade secrets, the data holder may withhold or, as the case may be, suspend the sharing of data identified as trade secrets. The decision of the data holder shall be duly substantiated and provided in writing to the third party without undue delay. In such cases, the data holder shall notify the competent authority designated pursuant to Article 37 that it has withheld or suspended data sharing and identify which measures have not been agreed or implemented and, where relevant, which trade secrets have had their confidentiality undermined.

11. In exceptional circumstances, where the data holder who is a trade secret holder is able to demonstrate that it is highly likely to suffer serious economic damage from the disclosure of trade secrets, despite the technical and organisational measures taken by the third party pursuant to paragraph 9 of this Article, that data holder may refuse on a case-by-case basis a request for access to the specific data in question. That demonstration shall be duly substantiated on the basis of objective elements, in particular the enforceability of trade secrets protection in third countries, the nature and level of confidentiality of the data requested, and the uniqueness and novelty of the connected product, and shall be provided in writing to the third party without undue delay. Where the data holder refuses to share data pursuant to this paragraph, it shall notify the competent authority designated pursuant to Article 37.

12. Without prejudice to the third party’s right to seek redress at any stage before a court or tribunal of a Member State, a third party wishing to challenge a data holder’s decision to refuse or to withhold or suspend data sharing pursuant to paragraphs 10 and 11 may:

13. The right referred to in paragraph 1 shall not adversely affect the rights of data subjects pursuant to the applicable Union and national law on the protection of personal data.
