The possibility of  SB papers being cited by patents is obviously higher than the proportion of all Web of Science (4.4 %) or MEDLINE covered  publications cited by patents (4 %) according to NAME_1 (2017) and NAME_2 (2018). The percentage 4 % is calculated  based on all papers indexed by Web of Science/MEDLINE, including the papers which have never been cited. According to an  investigation on the uncited papers in Web of Science (NAME_3 NAME_4, 2017), basically about one in fififth (21 %) publications  across all disciplines during 1900–2015 haven’t been cited. Setting papers published in 2006 as the sample, the proportion of  uncited papers within ten years after publication varies across different disciplines, for example 4 % for biomedical science,  8 % for chemistry, 11 % for physics, and 24 % for engineering and technology. Since these papers have no scientifific impact,  they are likely to have no technical impact and thus will probably not be cited by patents.
