Decreto-Lei n.º 02/2017, utilizações livres e reprodução técnica
A citation is an address, not a summary. The first part names the law; what follows narrows it to the exact section, article or paragraph.
In force since 17 April 2017.
A copyright and text and data mining (TDM) rule binding public and private bodies.
As of 6 September 2026.
What it requires
- A temporary, transient, or accessory reproduction that is an integral part of a technological transmission process, and has no independent economic significance, does not need the author's consent; this reaches ordinary network browsing and caching, but not a reproduction that modifies the transmitted content or interferes with the technology's lawful use.
- You may quote or summarize another's work, reproduce a short excerpt in reporting a current event, or reproduce an already-published current-affairs article on an economic, political, or religious topic (unless its reproduction right was expressly reserved), without the author's consent, but must name the author and publisher where possible and, for some of these uses, pay equitable remuneration.

What this law does
Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.
Article 75(1) excludes from the reproduction right a temporary act of reproduction that is transient or accessory, is an integral and essential part of a technological process, and whose sole purpose is to enable a network transmission between third parties by an intermediary or a lawful use with no independent economic significance; browsing and temporary storage that enable a transmission system's effective functioning are lawful on the same terms, provided the intermediary does not modify the transmission's content or interfere with a technology's lawful use as recognized by market practice.
Article 75(2) permits, without the author's consent, a regular selection of periodical press articles as a press review. It also permits the fixation or communication of short excerpts from a work when their use in reporting a current event is justified for information purposes. It further permits inserting citations or summaries of another's work in support of one's own views or for criticism, discussion, or teaching.
It also permits reproducing or communicating an already-accessible current-affairs article on an economic, political, or religious topic, unless its reproduction right has been expressly reserved. Article 76 conditions this free use on naming the author and publisher where possible, and on paying equitable remuneration to the author and publisher in the cases the article specifies.
No text-and-data-mining-specific exception, and no AI-training-specific rule, is stated separately from this general free-use framework, and the Code predates that concept. Infringing outside these exceptions is punished under article 197.
