CPC additionally includes the section, &#8220;Y&#8221;, related to general tagging of new technological developments. The main sections are:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A: Human Necessities&nbsp;<\/li><li>B: Performing Operations; Transporting&nbsp;<\/li><li>C: Chemistry; Metallurgy&nbsp;<\/li><li>D: Textiles; Paper&nbsp;<\/li><li>E: Fixed Constructions&nbsp;<\/li><li>F: Mechanical Engineering; Lighting; Heating; Weapons; Blasting Engines or Pumps&nbsp;<\/li><li>G: Physics&nbsp;<\/li><li>H: Electricity&nbsp;<\/li><li>Y: General Tagging of New Technological Developments&nbsp;<\/li><\/ul>\n\n\n\n<p>The EPO and USPTO both had highly developed patent classification systems, the\u202f<a href=\"http:\/\/wiki.iamip.com\/en\/articles\/2104465-ecla-european-patent-classification\" target=\"_blank\" rel=\"noreferrer noopener\">European CLAssification<\/a>\u202f(ECLA) and the United States Patent Classification (USPC) respectively. CPC is the outcome of an ambitious harmonization effort to bring the best practices from each Office together.\u202f&nbsp;<\/p>\n\n\n\n<p>CPC codes categorize patents by general subjects. The CPC codes are divided into sections A through Y, which are sub-divided into classes, subclasses, groups, and subgroups.\u202fFor more details see:\u202f<a href=\"https:\/\/worldwide.espacenet.com\/classification?locale=en_EP\" target=\"_blank\" rel=\"noreferrer noopener\">CPC Classification Search<\/a>,\u202fCPC Bulk data&nbsp;<a href=\"http:\/\/www.cooperativepatentclassification.org\/cpcSchemeAndDefinitions\/Bulk.html\" target=\"_blank\" rel=\"noreferrer noopener\"><br><\/a>The codes are hierarchical; therefore, the longer the code, the more specific the concept.\u202f&nbsp;<\/p>\n\n\n\n<p>Every patent document, regardless of whether it is an application or a granted patent, is given a classification symbol by the patent examiner indicating its allocation to a specific area of technology.&nbsp;<\/p>\n\n\n\n<p>The classifications are mainly used when performing patent searches and looking for prior art. It is therefore highly recommended to make use of these classifications as it will help minimize the amount of data to analyze. Instead of searching within over 100 million patents the search can be narrowed down to your area of interest.\u202f&nbsp;<\/p>\n\n\n\n<p>Not all patent offices use CPC. For example the\u202f<a href=\"https:\/\/www.dpma.de\/\" target=\"_blank\" rel=\"noreferrer noopener\">German Patent and Trademark Office (DPMA)<\/a>\u202fand the\u202f<a href=\"https:\/\/www.jpo.go.jp\/\" target=\"_blank\" rel=\"noreferrer noopener\">Japanese Patent Office (JPO)<\/a>\u202fuse IPC and their own classification systems like \u202f<a href=\"https:\/\/register.dpma.de\/register\/htdocs\/prod\/de\/hilfe\/klassifikationen\/patgbm\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">DEKLA<\/a>\u202fund\u202f<a href=\"http:\/\/patentwiki.iamip.com\/fi-and-f-terms-patent-classification\" target=\"_blank\" rel=\"noreferrer noopener\">FI Codes und F-terms<\/a>.&nbsp;<\/p>\n\n\n\n<p>Some of the patent offices that use CPC are:\u202f&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.uspto.gov\/patents-application-process\/patent-search\/classification-standards-and-development\" target=\"_blank\" rel=\"noreferrer noopener\">USPTO (US patent and trademark office)<\/a>&nbsp;<\/li><li><a href=\"https:\/\/www.epo.org\/news-issues\/news\/2011\/20111025.html\" target=\"_blank\" rel=\"noreferrer noopener\">EPO (European Patent Office)<\/a>&nbsp;<\/li><li><a href=\"http:\/\/www.kipo.go.kr\/\" target=\"_blank\" rel=\"noreferrer noopener\">KIPO (Korean Intellectual Property Office )<\/a>&nbsp;<\/li><li>SIPO (Chinese Patent Office)&nbsp;<\/li><li>ROSPATENT (Russian Patent Office)&nbsp;<\/li><li>INPI (Brasilien)&nbsp;<\/li><li>IMPI (Mexiko)&nbsp;<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>IamIP Platform:<\/strong>&nbsp;<\/h3>\n\n\n\n<p>In the IamIP platform, all IPC and CPC codes are summarized in the search view.
