An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The European Classification (ECLA) is a former patent classification system maintained by the European Patent Office (EPO). The ECLA classification system contains 134 000 subdivisions. It is mainly an extension of the International Patent Classification system, but sometimes modifies its titles and rules. ECLA is used in connection with the indexing system ICO, which serves to identify additional information and aspects that are not covered by the ECLA schemes. ECLA has been replaced by the Cooperative Patent Classification (CPC) as of 1 January 2013.

dbo:abstract
  • Am 1. Januar 2013 wurde die Europäische Patentklassifikation (European Classification System, ECLA) durch die Cooperative Patent Classification (CPC) ersetzt. Die Europäische Patentklassifikation wurde früher vom Europäischen Patentamt (EPA) intern für die Klassifizierung der Dokumentensammlungen sowie als Hilfsmittel bei der Recherche des Standes der Technik verwendet. Ihre baumartige Struktur war eine Feinunterteilung der Internationalen Patentklassifikation (IPC). In der letzten Version enthielt die ECLA ca. 134.000 sogenannte Symbole, die IPC zu diesem Zeitpunkt dagegen nur 70.000. Im Rahmen der Prüfertätigkeit am EPA wurde die ECLA laufend weiterentwickelt und in kürzeren Abständen (monatlich) als die IPC aktualisiert. Ein vollständiges ECLA-Symbol bestand aus einer Folge von Buchstaben und Ziffern und wurde als Datenfeld in der internen Dokumentendatenbank des EPA angegeben. Über esp@cenet waren ECLA-Symbole recherchierbar. (de)

  • 유럽특허분류(European Classification, ECLA)는 (EPO)에서 사용하는 독자적인 분류로 국제특허분류(IPC)와 함께 사용하고있다. ECLA는 IPC를 좀 더 세분화 한 것으로 일본의 FI와 비슷한 개념이지만 유럽 특허뿐만 아니라 미국이나 일본, 한국 등의 특허문헌에도 부여하고 있어 자국의 특허문헌만 부여하는 일본의 FI, F-Term이나 미국의 UPC와는 다르다. ECLA는 유럽특허청에서 검색 및 조회가 가능하다. (ko)
