Brazil

There are some court cases related to threshold of originality in Brazil. According to one study, and the court decisions contained in it, the concept of creativity in Brazil is way more strict and exigent than in the United States, and consequently the threshold of originality is considerably higher than the United States, which is the general reference in Commons.[2]

Examples:

  • OK. In the case of Boneco de Preço Miúdo (2011), puppets that were a tridimensional and humanized version of a logo were deemed by the court to lack enough originality to be protected. The court considered that there was no originality or unpublished work in the puppets because they represented an already existing symbol (the supermarket's logo), and that there were already previous 3D and humanized versions of that logo. The court did not grant any value nor legal protection to the specific 3D and humanized version of the logo in question, and called it something like a "stylization subordinate to a previous idea".[3]
  • OK. Copyright for compilations/ reorganizations of already existing elements has often been rejected on court, hinting that the threshold for what constitutes an "intellectual creation" in this respect is quite high in Brazil.[4]
  • OK. Slogans are generally acceptable. In rare occasions they may be protected, when there is such a level of creativity as to attain the level of a literary work. For example, in the Guerra das Moedas court case (2013), copyright in the expression was not recognized by the court. The verdict stated that the language is the cultural patrimony of the people, so language expressions can't be protected by law. The Rede Globo vs. Ronaldo Ciambroni case was similar.[5][6]

Some examples help define which photos are, and are not, "artistic creations", and therefore object of protection under the 1973 copyright law:

  • OK. The facade of the Jung Frau building, in Joinville, as well as partial views of the city, when photographed in an obvious simple way, without employment of any special ("diferenciada") technique". The court ruled: "photographs are not considered artistic creations ... that portray in a manifestly simple way, without use of any differentiated technique, the front of a residential building and a partial view of the city, under a service contract with a real estate business with a predefined advertising purpose"[7]
  • OK. Simple documentary, descriptive photographs in general, such as photographs documenting social reunions: In SC-AC 111630 SC 2002.011163-0 (2006): "mere photographic documentation, without artistic character, does not qualify for copyright ... making it possible to use a copy without mention of the photographer's name, since, according to Brazilian law, only artistic photography (by choice of the object and conditions of execution) is listed among protected works. ... [for example] with documentary photographs of social gatherings, where the author was performing duties for the defendant, a reference to the photographer's name is not required because it is not an artistic work..."[8]
  • OK. A 2000 ruling stated: "Photographs for identity documents, produced by automatic machines, are not artistic works. ... Neither should purely technical photographs, which reproduce a certain object without the slightest artistic concern, be protected by copyright."[9]
  •  Not OK Another 2000 decision stated: "the photos [...] have an artistic character characterized by the originality, creativity and technique of its author, elements that reveal ... a work of art. They are not, as the appellant claims, mere reproductions of images for advertising purposes, or common snapshots."[10]

Puppets who were a tridimensional and humanized version of this logo were deemed in court to lack enough originality to be protected.

Canada

Unlike other common law countries, Canada's threshold of originality veers closer to that of the United States. CCH Canadian Ltd. v. Law Society of Upper Canada explicitly rejected the "sweat of the brow" doctrine for being too low of a standard, but at the same time, stated that the creativity standards for originality were too high:

A creativity standard implies that something must be novel or non-obvious — concepts more properly associated with patent law than copyright law. And for these reasons, I conclude that an “original” work under the Copyright Act is one that originates from an author and is not copied from another work. That alone, however, is not sufficient to find that something is original. In addition, an original work must be the product of an author’s exercise of skill and judgment. The exercise of skill and judgment required to produce the work must not be so trivial that it could be characterized as a purely mechanical exercise."

The same case also stated:

For a work to be “original” within the meaning of the Copyright Act, it must be more than a mere copy of another work. At the same time, it need not be creative, in the sense of being novel or unique. What is required to attract copyright protection in the expression of an idea is an exercise of skill and judgment. By skill, I mean the use of one’s knowledge, developed aptitude or practised ability in producing the work. By judgment, I mean the use of one’s capacity for discernment or ability to form an opinion or evaluation by comparing different possible options in producing the work. This exercise of skill and judgment will necessarily involve intellectual effort.

Registration in the Intellectual Property Registry generates a "presumption" of copyright in favor of the registrant. Any work may be registered for "presumed" copyright, but Law No. 17.336 clearly states the "presumed" copyright may be contested. That is because, as established in "Astorga Sánchez José / Inversiones C. S. A.", C-2470-2009, 17.° Juzgado Civil de Santiago (28 October 2011), the Intellectual Property Conservator (Conservador) only makes the deposit of the documents into the registry, does not make an examination of their originality, or to determine whether the deposited documents are works or not, and so certificates of intellectual property generated by the Intellectual Property Registry do not establish that a work is new, original or viceversa. The Conservator of Intellectual Property expressed in 2011 it is up to the judicial system "to carry out an originality test to define whether the creation is indeed a particular manifestation of human ingenuity that can be classified as original compared to other equivalent creations, analyzed from a subjective perspective, that is, that the imprint or trace of the author can be perceived, that allows it to stand out from others". Such pronouncement was adhered to by the 17th civil judge of Santiago.[11]

Indecopi established parameters to qualify the originality of graphic and photographic compositions. Because of the higher originality threshold (independent of its endeavour, novelty, inspiration and technique, the requirement is to leave some space for the development of its author's personality, not a copy or imitation, referred as "originalidad subjetiva"),[13] simple designs, non-production videographic creations and old photographs without demonstrating their individuality can be uploaded to Commons. See also Andean Community: Threshold of originality.

Simple photographs[edit]

Old published photographs have a copyright term of 20 years counted from the first of January of the year following that of the disclosing of the photograph before 1976. The notes shown are based on the rescinded 1961 law:

  • For old pictures taken prior to 31 December 1975 and which were not published within an author's own work  fail to meet the general definition of a "work" under 1961 law (and Article 3.4 of Universal Copyright Convention: "The provisions […] not apply to photographic works […] shall not be less than ten years").[14] The duration of the photograph was for 20 years after performed its first copy, without the author presenting this in a literary, scientific or documentary work, from January 1 of the following year.[13714/1961 Art. 27] They were not renewed during the URAA date.[13714/1961 Art. 27 and 57] Use {{PD-Peru-photo}}.
  • The duration is reduced if the following occurs: when the author did not place the name of the label with the message "Reproduction prohibited" or that the author published in a work without a full name or under an unknown pseudonym.[13714/1961 Art. 58] The duration of anonymous works prior to 31 December 1980 was 15 years after publication and expired on 1 January 1996. They were not renewed during the URAA date. Use {{PD-Peru-anonymous}}.
  • If they were used in literary or scientific works, they were documentary works or are reproductions of artistic material "of private domain", and the author died before 1946 (of before 1966 if someone had no family heirs), the law considers the photographs as the author's work (life + 30/50 years).[14] In the case of collective works, the date is considered to be the last survivor. If they died after 1947, they are protected by the current law. Use {{PD-Peru-1961law}}.

Recent published photographs below threshold have a copyright term of 70 years counted from the first of January of the year following that of the taking of the photograph. Fortunately, this term usually flexible in the cases and facts shown below:

  • The general definition of a "work" in the 1996 law is "any personal and original intellectual creation capable of being disclosed or reproduced in any form that is or may yet become known".[822/1996 Art.2(17)] Simple photographs taken or disclosed since 1976 are those which  fail to meet the general definition of a "work" and only receive neighbouring rights,[822/1996 Art.144] but works above this threshold will receive standard protection (life + 70 years, see below).
  • The Court of Indecopi believes that originality in a photograph should be limited to the originality of any work, requirements to protect against plagiarism. According to article 3.c of the Regulation of Inscriptions in the Registry National Copyright Act, provides that "no may be subject to registration the photographs that are limited to simple reproductions of people, of things, or of objects already existing or showing a mere documentary character [...] photography to be a work can not constitute only a simple reproduction of already existing objects".[15]
  • Derecho PUCP journal explains examples of highly distinguishable events that surpass the threshold of originality: creative use of lights, unique moment, transmission of a message in their work and the photographer's personality. Below these and other criteria, simple photographs are legislated under Legislative Decree 1044 on unfair competition.[16]

Examples for photographs under 1961 law:

Examples for photographs under 1996 law:

  • In 2002 the Court considered two images of household appliances as below of threshold of originality due to the lack of creative evidence, despite they are in a catalog with individuality. See Resolution No 354-2002/TPI-INDECOPI.[17]
  • Also, in 2002 the Court ruled that a magazine photograph of Skándalo boy band in ordinary dress and solid-colored background receives related rights-only because it lacks individuality. See Resolution No 378-2002/TPI-INDECOPI, Alomi Producciones S.A.C. v Karinto S.A p.13.[15]
  • In 2007 the Court justified a photograph of gift box for a web catalog as original work because of its shade selection and during the editing process it carried meticulous details, specifically the colored shade artificially created. See Resolution No 1263-2007/TPI-INDECOPI, Enrique Capella v Grupo Americano de Comercio S.A.C. and Citybank del Perú S.A p.4.[18]
  • In 2008 the court determined that press snapshots of sporting, political or weather events lack originality for lack of prior preparation in their production. See Resolution No 2521-2008/TPI-Indecopi, Agencia Efe S.A. v Las Rosas Editorial S.A.C.
  • In 2012 the Court concluded that non-artistic techniques of photographs are not protectable (for example, scanning). See Resolution No 059-2012/TPI-Indecopi and Indecopi (2015), p.75.[19]
  • In 2013 Indecopi deduced that a promotional photograph of a model wearing clothes of a textile company does bear originality due to the framing, focus and composition to highlight her outfit. See Resolution No 0384-2013/CDA-INDECOPI, Peruvian Connection Ltd. v SENATI p. 9 and 10.[20]
  • In 2021 the criteria for originality of photographs were simplified to three points: transmittable, framed and lighting that shows their personality. Between pages 77 and 82 of this resolution the court evident that press photographs from Hildebrandt en sus trece magazine do carry originality because they focus on the gestures of the photographed and the depth of the camera. See Resolution No 0096-2021/TPI-INDECOPI, Plutón Editores S.A.C. v DP Comunicaciones S.A.C..
Videographic process[edit]

There is threshold of originality for audiovisual creations but their protection is similar for both works and recordings (publish/create + 70 years). While cinematographic works ("obra audiovisual") are protected in their entirety, the related rights can only be granted to the producer of non-artistic filming ("grabación audiovisual"),[822/1996 Art. 140] which also include performance and broadcasting.[822/1996 Art. 143] Resolution 000111-1999-ODA-INDECOPI establishes differences between the two terms, in particular, and in a similar way to simple photographs, the fixation of the succession of images. But, Resolution 371-2001/TPI-INDECOPI establishes that the main requirement to receive related rights from the producer of non-artistic filming consists of: "present in their creation process a certain degree of creativity, technical or organizational skill sufficient to justify the recognition of a similar right in their favor" (p.e. Pay-per-View events).

Theoretically, a security camera captures in a public place could  lack of their producer (as a public asset is mainly assumed to Peruvian State) to be in the public domain. Security camera footage from Sistema Nacional de Seguridad Ciudadana is provided anonymously to the Peruvian National Police or Public Prosecutor's Office like state cameras in public areas, there is no knowed evidence from the original producer of the material.[N° 007-2020-IN Art. 18] Opinión Consultiva 60-2019-JUS/DGTAIPD indicates that footage records are disclosure if these are for public interest and share in open data process (see also Works by the Peruvian Government ),[N° 007-2020-IN Art.22] the places filmed correspond to "places of public domain",[N° 007-2020-IN Art. 7] human monitoring exists but does not interfere with the surveillance camera's technical or creative ability for recording.[N° 007-2020-IN Art. 2] Also it isn't artistic work since its custody cannot be altered from the original,[N° 007-2020-IN Art. 19] as a result, the footage is below the threshold of originality and don't comply with related rights of article 143 of the 1996 law.[21][22] Moral rights prevail of the person involved in this media. For these footage in official works, use {{PD-PE-exempt}}.

Logos, designs and other works[edit]

Simple or ordinary logos and designs are OK to upload to Commons, because they are below the threshold of originality required for copyright protection. In words of Indecopi and Ministry of Justice and quoting Resolutions No. 1349-2001/TPI-INDECOPI (first paragraph) and 0286-1998/TPI-INDECOPI (second paragraph):

According to Article 3 of Decision 351 [of the Andean Decision], in accordance with Article 2 of Legislative Decree No. 822, a work is understood to be any original intellectual creation of an artistic, scientific or literary nature, susceptible of being disclosed or reproduced in any form.[...] Whatever already part of the cultural heritage -artistic, scientific or literary- will not be considered [original creation], nor will [original] the form of expression that derives from the nature of things or from mechanical-only application of the provisions of certain legal norms, nor will [original] the form of expression that is reduced to a simple technique or simple instructions that only require manual skill for this execution.

—Indecopi, La originalidad como requisito de protección por derechos de autor ("requisito de la originalidad"), Precedentes y normativa del Indecopi en Propiedad Intelectual (2015)[19]

In 18th paragraph in Casación Número: 1686-2011 explains the use of originality with architectural works satisfying utilitarian functions:

The originality of the architectural work [...] must be sought essentially in the creative features that are most distinguishable from the purposes of the model, its nature, its geographic and landscape context, and the functional requirements of the costumer, as well as the technical and urban planning standards applicable to the case; and respond rather, in a particular way or as totality, to the individuality or artistic personality of the author. [An] architectural model [...] must be subjected to analysis for the purpose of identifying whether they respond only to elements of functionality or natural characteristics of the species to which they belong or, on the contrary, contain features that correspond to the whim or personality that the author has wanted to attribute to them, beyond their functionality or technical rigor, resulting in giving individuality to the work, in relation to the rest of the constructions of its species.

Note: Some creations are above the threshold of originality and  are not valid for upload to Commons:

  • Logo of Tres Olivas: a leaf with three olives with tonalities, use of brightness and sensation of movement. See Resolution No 1774-2012/TPI-INDECOPI, Olivos del Sur S.A.C. vs Antonio Moncayo Cortés.[26]
  • Emblema La Primera. See Resolution No 2361-2016/TPI-INDECOPI.
  • A fictional character in Superman: Krisis of the Krimson Kryptonite. See Resolution No 1164-2014/TPI-INDECOPI.
  • A logo with a people with torch to the letter E, above the letter T. Triunfo Empresarial. See Resolution No 0319-2018/TPI-INDECOPI.

These images are OK to upload to Commons, because they are below the threshold of originality required for copyright protection.

Despite repeated requests, the US Copyright Office found the Vodafone speechmark (shaded version) ineligible for copyright protection. It cannot, however, be uploaded to Commons because it's a UK logo.

These are  Not OK to upload to Commons (unless published under a free license by the copyright holder), because they are above the threshold of originality required for copyright protection.

Paintings

 Not OK for most paintings.

Even seemingly simple paintings consisting of geometric shapes are often copyrighted due to details that may not be immediately obvious to the viewer.

  • Photographic reproductions of paintings by Mark Rothko have been granted registration by the US Copyright Office, so it is reasonable to assume that the original works are also copyrighted.
Other

Although the threshold of originality for non-graphic works (such as architecture and sound recordings) follow the same standards, such cases can be difficult to determine.

  • The five-note melody that typically accompanies Intel's logo was granted copyright protection because it "combined and blended synthesized, digital sounds" and was "refined and mastered with a special spatial enhancer." [29]
  • Anish Kapoor's Cloud Gate is a relatively simple 3D sculpture that was deemed eligible for copyright (VA0001983425)
  • The replica of public domain object Statue of Liberty in New York-New York Hotel and Casino is deemed eligible for copyright, also the United States Postal Service is being sued for copyright infringement for famously (and mistakenly) using this statue instead of the real Statue of Liberty on its Forever stamps.
