English abstract

A scientometric study was performed to assess the quantitative trend of patent literature in MEDLINE throughout 1965-2005. The kind of languages, publication type, journals, and the origin of published documents were presented. The study showed that the growth of patent literature in MEDLINE with an annual growth of 11.4% was 3.6 times higher than the common growth of the MEDLINE database which had an annual growth of 3.1% through 1965-2005. More than 90% of all documents indexed as "patents" in MEDLINE were in English followed by Russian (4.12%), French (1.36%) and German (1.20%). The origin country of four documents stayed unknown (in MEDLINE). Journal "Nature" with publishing 14% of all documents, indexed as patents (patent literature) in PubMed was the most prolific periodical, followed by journal "Science" with 8%, "Nature-biotechnology" with 8%, "Lancet" with 2%, "BMJ" with 2%, "New Scientist" with 2% and "Food and drug law" with 1% respectively. From a total of 31 publications kind regarding to the documents indexed as patents in MEDLINE with a total frequencies of 3,207 titles, 46% of all publications were in the form of journal Articles, 22% in the form of News, 5% Letter, 5% Comment, 4% Review, 3% Editorial, 2% Newspaper Article, 2% Research Support, 2% English Abstract. The rest were less than 2%. The proportion of publications in English showed considerable growth through 1965-2005. It reached from 52% in 1965 to 90% in 2005 an increase of 72%. Analysis of study predicted that the percentage of publications in English in MEDLINE will reach to the saturation level at 97% in 2030. This indicates that the editorial policy of entering data to the database of MEDLINE is being changed, and the atention of policy makers in this database have focused on the literature of science in English.
