Without going into any controversial issues regarding the patent system, we approach a very real and growing problem: searching for innovation. The target collection for this task does not consist of patent documents only, but it is in these documents that the main difference is found compared to web or news information retrieval. In addition, the issue of patent search implies a particular user model and search process model. This review is concerned with how research and technology in the field of Information Retrieval assists or even changes the processes of patent search. It is a survey of work done on patent data in relation to Information Retrieval in the last 20\u201325 years. It explains the sources of difficulty and the existing document processing and retrieval methods of the domain, and provides a motivation for further research in the area.<\/jats:p>","DOI":"10.1561\/1500000027","type":"journal-article","created":{"date-parts":[[2013,2,19]],"date-time":"2013-02-19T05:35:29Z","timestamp":1361252129000},"page":"1-97","source":"Crossref","is-referenced-by-count":59,"title":["Patent Retrieval"],"prefix":"10.1108","volume":"7","author":[{"given":"Mihai","family":"Lupu","sequence":"first","affiliation":[{"name":"Vienna University of Technology, Favoritenstra\u00dfe 9-11\/188, Vienna, 1040 ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allan","family":"Hanbury","sequence":"additional","affiliation":[{"name":"Vienna University of Technology, Favoritenstra\u00dfe 9-11\/188, Vienna, 1040 ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"140","published-online":{"date-parts":[[2013,2,20]]},"reference":[{"key":"2026040314275576800_ref001","unstructured":"[1]\n          \u201cThe clueweb dataset,\u201d http:\/\/lemurproject.org\/clueweb09.php\/index.php."},{"key":"2026040314275576800_ref002","unstructured":"[2]\n          \u201cManual of patent examination procedure, section 608.01 (m),\u201d Revision July2010, http:\/\/www.uspto.gov\/web\/offices\/pac\/mpep\/index.htm."},{"key":"2026040314275576800_ref003","unstructured":"[3]\n          \u201cUnderstanding intellectual property,\u201d http:\/\/www.wipo.int\/about-ip\/en\/."},{"key":"2026040314275576800_ref004","author":"PATENT \u201903: Proceedings of the ACL-2003 Workshop on Patent Corpus Processing","year":"2003"},{"key":"2026040314275576800_ref005","author":"PaIR Al: Proceedings of the Workshop on Patent Information Retrieval","year":"2011"},{"key":"2026040314275576800_ref006","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/S0172-2190(00)00110-1","article-title":"Comparing the IPC and the US classification systems for the patent searcher","volume":"23","author":"Adams","year":"2001","journal-title":"World Patent Information"},{"key":"2026040314275576800_ref007","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1016\/j.wpi.2004.12.005","article-title":"Electronic non-text material in patent applications-some questions for patent offices, applicants and searchers","volume":"27","author":"Adams","year":"2005","journal-title":"World Patent Information"},{"key":"2026040314275576800_ref008","article-title":"New methodologies for patent searching;
