The usefulness of patent literature for research and development is mostly unknown. Therefore a specific patent retrieval has been carried out concerning calcium phosphate-containing biomaterials. This research field includes chemical, medical, and engineering problems and is of importance to the development of bioactive materials for bone replacement. The preliminary work includes information on the characteristics and the availability of patent literature as well as about patent classification systems according to which the documents are filed in patent collections. By reading the non-patent literature searching questions can be formulated. The proper patent retrieval starts with the study of secondary literature especially that in Chemical Abstracts, which report on patents since 1907. The structure of Chemical Abstracts, their indexes and sections help to find relevant patents of chemical or chemical engineering contents fast and inspire to read patents of bordering areas. This retrieval from Chemical Abstracts led to 171 patents disclosed 1975-1985 and to 95 patents disclosed in 1986; the latter are listed in a table. The contents of the abstracts inform on the research activity and help to reduce time and effort for a continuation of the retrieval in a patent collections or database.
专利文献对研发的有用性大多不为人知。因此，针对含磷酸钙生物材料开展了一项特定的专利检索。该研究领域涵盖化学、医学和工程问题，对用于骨替代的生物活性材料的开发具有重要意义。初步工作包括有关专利文献的特点和可得性的信息，以及关于专利分类系统的信息，专利文献就是依据这些分类系统归档于专利文献库中的。通过阅读非专利文献，可以提出检索问题。恰当的专利检索始于对二次文献的研究，尤其是自1907年起就报道专利的《化学文摘》中的二次文献。《化学文摘》的结构、索引和栏目有助于快速找到化学或化学工程领域相关的专利，并激发人们去阅读相邻领域的专利。从《化学文摘》中检索到1975年至1985年公布的171项专利以及1986年公布的95项专利；后者列于一个表格中。摘要的内容反映了研究活动情况，有助于减少在专利文献库或数据库中继续检索所需的时间和精力。
