Patent Classification
A patent classification is a system for examiners of patent offices or other people to categorize (code) documents, such as published patent applications, according to the technical features of their content. Patent classifications make it feasible to search quickly for documents about earlier disclosures similar to or related to the invention for which a patent is applied for, and to track technological trends in patent applications. Searches based on patent classifications can identify documents of different languages by using the codes (classes) of the system, rather than words. Patent classification systems were originally developed for sorting paper documents, but are nowadays used for searching patent databases. The International Patent Classification (IPC) is agreed internationally. The United States Patent Classification (USPC) is fixed by the United States Patent and Trademark Office (USPTO). The Derwent classification system is fixed by an enterprise. The German Patent ...

Patent Examiner
A patent examiner (or, historically, a patent clerk) is an employee, usually a civil servant with a scientific or engineering background, working at a patent office. Major employers of patent examiners are the European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the Japan Patent Office (JPO), and other patent offices around the world. Duties Patent examiners review patent applications to determine whether the invention(s) claimed in each of them should be granted a patent or whether the application should instead be refused. One of the most important tasks of a patent examiner is to review the disclosure in the application and to compare it to the prior art. This involves reading and understanding a patent application, searching the prior art (including prior patent applications and patents, scientific literature databases, etc.) to determine what contribution the invention makes over the prior art, and issuing office actions to explain to the applica ...

Patent Application
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office. To obtain the grant of a patent, a person, either legal or natural, must file an application at a patent office with the jurisdiction to grant a patent in the geographic area over which coverage is required. This is often a national patent office, but may be a regional body, such as the European Patent Office. Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification. The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with a patent offic ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

International Patent Classification
The International Patent Classification (IPC) is a hierarchical patent classification system used in over 100 countries to classify the content of patents in a uniform manner. It was created under the Strasbourg Agreement (1971), one of a number of treaties administered by the World Intellectual Property Organization (WIPO). The classification is updated on a regular basis by a Committee of Experts, consisting of representatives of the Contracting States of that Agreement with observers from other organisations, such as the European Patent Office. Classification Patent publications from all of the Contracting States (and also most others) are each assigned at least one classification symbol indicating the subject to which the invention relates and may also be assigned further classification symbols and indexing codes to give further details of the contents. Each classification symbol is of the form A01B 1/00 (which represents "hand tools"). The first letter represents the "section ...

United States Patent Classification
The United States Patent Classification is an official patent classification system in use and maintained by the United States Patent and Trademark Office (USPTO). It was mostly replaced by the Cooperative Patent Classification (CPC) on January 1, 2013. Plant and design patents are still classified solely within USPC at the USPTO. As of December 2018, patents at the USPTO are still routed to their appropriate business and art units by their USPC, even though it is no longer assigned directly to the patents themselves. Overview There are over 400 classes in the U.S. Patent Classification System, each having a title descriptive of its subject matter and each being identified by a class number. Each class is subdivided into a number of subclasses. Each subclass bears a descriptive title and is identified by a subclass number. The subclass number may be an integral number or may contain a decimal portion and/or alpha characters. A complete identification of a subclass requires both th ...

United States Patent And Trademark Office
The United States Patent and Trademark Office (USPTO) is an agency in the U.S. Department of Commerce that serves as the national patent office and trademark registration authority for the United States. The USPTO's headquarters are in Alexandria, Virginia, after a 2005 move from the Crystal City area of neighboring Arlington, Virginia. The USPTO is "unique among federal agencies because it operates solely on fees collected by its users, and not on taxpayer dollars". Its "operating structure is like a business in that it receives requests for services—applications for patents and trademark registrations—and charges fees projected to cover the cost of performing the services tprovide . The Office is headed by the Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office, a position last held by Andrei Iancu until he left office on January 20, 2021.

Derwent World Patents Index
The Derwent World Patents Index (DWPI) is a database containing patent applications and grants from 44 of the world's patent issuing authorities. Compiled in English by editorial staff, the database provides a short abstract detailing the nature and use of the invention described in a patent and is indexed into alphanumeric technology categories to allow retrieval of relevant patent documents by users. Each record within the database defines a patent family, the grouping of patent documentation recorded at the various patent offices as protection of an invention is sought around the world. Each patent family is grouped around a Basic Patent, which is usually the first published example of the invention. All subsequent filings are referred back to the Basic Patent, and are referred to as Equivalent Patents. On this basis, the database has some 20 million "inventions", corresponding to tens of millions of patents, with almost a million new inventions added each year. From 2008, the ...
