Identification of Goods And/Or Services

A written statement of the goods and/or services included in an application. Every application must include an identification of goods and/or services. If you fail to list any recognizable goods or services, the USPTO will return the application and refund the fee. When specifying the goods and/or services, applicants should use clear, concise terms, i.e., common commercial names and language that the general public easily understands.
Please note that the terms in the class headings or short titles of the classes in the "International Classification of Classes of Goods and Services" are generally too broad and should not be used alone as an identification. Also, an international class number alone is never an acceptable listing.

In-situ Conditions

According to article 2 of the Convention on Biological Diversity (1992): “In-situ conditions” means “conditions where genetic resources exist within ecosystems and natural habitats, and, in the case of domesticated or cultivated species, in the surroundings where they have developed their distinctive properties.”

Independent Claim

A claim that does not refer back to or depend on another claim. As the EPO describes: "All applications will contain one or more "independent" claims directed to the essential features of the invention." An independent claim therefore, comprises the broadest definition of an invention and is a standalone statement. It may be limited in scope by dependent claims.

Indigenous Knowledge

Indigenous knowledge is knowledge held and used by communities, peoples and nations that are “indigenous”. In this sense, “indigenous knowledge” would be the traditional knowledge of indigenous peoples. Indigenous knowledge is, therefore, a part of the traditional knowledge category, but traditional knowledge is not necessarily indigenous. Yet the term is also used to refer to knowledge that is itself “indigenous”. In this sense, the terms “traditional knowledge” and “indigenous knowledge” may be interchangeable.

Indigenous Peoples

The term “indigenous peoples” has been the subject of considerable discussion and study and there is no universal, standard definition thereof. The United Nations Declaration on the Rights of Indigenous Peoples (2007) acknowledges the equal human rights of indigenous peoples against cultural discrimination and seeks to promote mutual respect and harmonious relations between the indigenous peoples and States. However, it does not provide a definition of “indigenous peoples”

Indigenous and Local Communities

The term “indigenous and local communities” has been the subject of considerable discussion and study and there is no universal, standard definition thereof. The term is used in the Convention on Biological Diversity (1992). Article 8(j) states that “[e]each Contracting Party shall, as far as possible and as appropriate: … (j) Subject to its national legislation, respect, preserve and maintain knowledge, innovations and practices of indigenous and local communities embodying traditional lifestyles relevant for the conservation and sustainable use of biological diversity and promote their wider application with the approval and involvement of the holders of such knowledge, innovations and practices and encourage the equitable sharing of the benefits arising from the utilization of such knowledge, innovations and practices; …”. The same term is used in the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity (2010).

Industrial Design

A design process used for products that will be manufactured via mass production methods.

Informal Application

For patent applications filed under 35 U.S.C. §111(a), applicants and other individuals who are substantially involved in preparing or prosecuting a patent application must submit to the Office information which is material to patentability (could render a claim unpatentable) as defined in 37 CFR Section 1.56. The provisions of 37 CFR Section 1.97 and 37 CFR Section 1.98 provide a mechanism for compliance with the duty of disclosure provided in 37 CFR Section 1.56.
The IDS must include a list of all patents, publications, U.S. applications, or other information submitted for consideration by the Office. The USPTO provides forms for use in the submission of an IDS, the PTO/SB/08a and PTO/SB/08b.

Infringement

An infringement is an act that interferes with one of the exclusive rights of an intellectual property right owner. Specifically, in the field of copyright and related rights, infringement is an act carried out in respect of a work protected by copyright or an object of related rights without authorization of the owner of the copyright or related rights concerned where such authorization is required. The liability for infringement may exist not only on the basis of direct liability (for the performance of the unauthorized act in itself), but also on the basis of “contributory liability” or “vicarious liability.”

Intangible Cultural Heritage

“Intangible” refers to something that lacks a physical form. “Tangible” on the other hand is defined as “having or possessing physical form; capable of being touched and seen; perceptible to the touch.”. “Intangible cultural heritage” is defined in the United Nations Education, Science And Culture Organization (UNESCO) Convention for the Safeguarding of the Intangible Cultural Heritage (2003) as “the practices, representations, expressions, knowledge, skills – as well as the instruments, objects, artifacts and cultural spaces associated therewith – that communities, groups and, in some cases, individuals recognize as part of their cultural heritage. This intangible cultural heritage, transmitted from generation to generation, is constantly recreated by communities and groups in response to their environment, their interaction with nature and their history, and provides them with a sense of identity and continuity, thus promoting respect for cultural diversity and human creativity

Integrity

The right of integrity is the right to prevent unauthorized alterations and changes to works. After the 1949 Brussels Revision of the Berne Convention for the Protection of Literary and Artistic Works (1971), the prohibition of other derogatory actions in relation to the said work which would be prejudicial to the author’s honor or reputation was added (Article 6bis).

Intellectual Property Guidelines for Access and Benefit-sharing

From its first session, the IGC supported a task which would lead to the development by WIPO of Intellectual Property Guidelines for Access and Benefit-sharing. It was proposed that the Guidelines be based on a systematic survey of actual and model contractual agreements in the form of the WIPO Database of Biodiversity-related Access and Benefit-sharing Agreements.A first draft was prepared taking into account the operational principles identified by the IGC for the development of such Guidelines.80 This draft was later updated for purposes of the seventeenth session of the IGC.

Inter Partes Reexamination

Inter partes reexamination practice primarily differs from ex parte practice in that the third party requester may file written comments addressing issues raised by the patent owner in a response to Office action.

International Application

1. An application filed under the Patent Cooperation Treaty. 2. Allows a trademark owner to seek registration in any of the countries that have joined the Madrid Protocol by filing a single application.

International Patent Classification

The International Patent Classification (IPC) is “a hierarchical system in which the whole area of technology is divided into a range of sections, classes, subclasses and groups. The Classification is a language independent tool indispensable for the retrieval of patent documents in the search for ‘prior art’.” The IPC was established by the Strasbourg Agreement Concerning the International Patent Classification (1971). Article 2(1)(a) provides that “[t]he Classification comprises: (i) the text which was established pursuant to the provisions of the European Convention on the International Classification of Patents for Invention of December 19, 1954 (hereinafter designated as the “European Convention”), and which came into force and was published by the Secretary General of the Council of Europe on September 1, 1968; (ii) the amendments which have entered into force pursuant to Article 2(2) of the European Convention prior to the entry into force of this Agreement; (iii) the amendments made thereafter in accordance with Article 5 which enter into force pursuant to the provisions of Article 6.”

International Treaty on Plant Genetic Resources for Food and Agriculture

The International Treaty on Plant Genetic Resources for Food and Agriculture (the ITPGRFA) was adopted by the Thirty-First Session of the Conference of the Food and Agriculture Organization of the United Nations on November 3, 2001, and entered into force in 2004. The Treaty aims at: (1) recognizing the enormous contribution of farmers to the diversity of crops that feed the world; (2) establishing a global system to provide farmers, plant breeders and scientists with access to plant genetic materials; and (3) ensuring that recipients share benefits they derive from the use of these genetic materials with the countries where they have been originated.

Invention

Any art or process (way of doing or making things), machine, manufacture, design, or composition of matter, or any new and useful improvement thereof, or any variety of plant, which is or may be patentable under the patent laws of the United States.

Inventive Step

Inventive step (also referred to as “non-obviousness”) is one of the criteria of patentability and relates to the question of whether the invention would have been obvious to a person skilled in the art. According to article 33 of the PCT, a claimed invention shall be considered to involve an inventive step “if, having regard to the prior art as defined in the Regulations, it is not, at the prescribed relevant date, obvious to a person skilled in the art.” Article 56 of the European Patent Convention and Section 35 U.S.C. §103 provide for similar definitions. Section 35 U.S.C. §103 uses the equivalent term “non-obvious subject matter.”

Inventor

One who contributes to the conception of an invention. The patent law of the United States of America requires that the applicant in a patent application must be the inventor.

Issue Date

The date that a patent application becomes a US patent.
The issue date is the date that patent rights can be exercised. U.S. patents are always issued on Tuesdays.
