NGS Patstat data

The datasets included in the repository concern results obtained following patent searches performed by means of Patstat online (https://www.epo.org/searching-for-patents/business/patstat.html#tab-1). The analysis performed by means of Patstat online during Dec. 2019 using the Autumn 2019 edition of Patstat is quite complex therefore has been organised according to the following five objectives: 1) the files named ‘C1 – C4’ are included in the folder ‘Coverage NGS’ and are essentially aimed at determining the amount of patent families corresponding to patent applications filed considering the Next Generation Sequencing techniques/tools or the more generic item dealing with genomic sequencing. Another aim is that of ranking the applicants specifically dealing with the NGS matter. A pdf file includes a list of the patent documents in order to show that the found results effectively deal with NGS. 2) The files named ‘N1 – N2’ (‘Normalization NGS’) allow to determine the number of patent applications specifically concerning the NGS matter and filed to different national patent authorities. It may be reasonably assumed that if one geographical area is much wider and characterised by a higher number of residents than a second one, in the former case a higher number of filed patent applications than in the latter case would be reasonable, unless the normalization of the data would rather reveal a preferential specialization or commitment of one territory toward a specific technical item. 3) The files named ‘Q1 – Q5’ are the results of search criteria aimed at determining the average quality of the technical content of pooled patent documents. As detailed in the ‘Quality NGS’ folder content, qualitative considerations may benefit from knowledge regarding the differentiation between competitors based on parameters such as the residual validity of the patents, the number of fee payments, the dimension of the patent family or the number of forward citations of a patent document. 4) The files named ‘S1 – S4’ are aimed at elucidating the collaborations occurred in a specific time-frame between one applicant and one patent attorney. Cases in which two applicants, having collaborated with the very same patent attorney, can be considered as competitors or collaborators (co-assignees according to the possibility of co-filing a patent application), could emerge by means of such search phase. 5) The files named ‘E1 – E8’, included in the ‘NGS Evolution’ folder, contain data regarding four nucleic acids sequencing techniques currently acknowledged as state of the art. Such files are aimed at evaluating and compare the trends corresponding to each of these techniques, estimated by means of the number of patent families and also aimed at identifying the players on the basis of the level of their commitment toward each of the four technologies, as detailed in the ‘NGS Evolution’ folder.本仓库收录的数据集，均源自通过专利统计数据库（Patstat）在线平台开展的专利检索结果，检索平台官方网址为https://www.epo.org/searching-for-patents/business/patstat.html#tab-1。本次分析于2019年12月依托Patstat 2019秋季版完成，分析流程较为复杂，因此按照以下五大目标进行组织： 1. 命名为“C1–C4”的文件收录于“Coverage NGS”文件夹中，其核心目标有二：一是统计基于下一代测序（Next Generation Sequencing, NGS）技术/工具或更通用的基因组测序相关专利申请对应的专利家族数量；二是对专注于NGS领域的专利申请人进行排名。另有一份PDF文件列出了本次检索得到的专利文献，以验证所得结果确实与NGS领域相关。 2. 命名为“N1–N2”的文件隶属于“Normalization NGS”文件夹，用于统计专门针对NGS领域且向不同国家专利机构提交的专利申请数量。可合理假设：若某一地理区域的范围更广、常住人口规模更大，则该区域的专利申请数量通常会高于范围更小的区域；但若对数据进行标准化处理，则可揭示特定地区在某一技术领域是否存在优先的专业化布局或研发投入倾向。 3. 命名为“Q1–Q5”的文件为特定检索策略的分析结果，用于测算聚合专利文献的技术内容平均质量。正如“Quality NGS”文件夹中详述的内容，基于专利剩余有效期、年费缴纳次数、专利家族规模或专利文献被引次数等参数区分竞争对手的定性分析，可借助本次分析结果获得有效支撑。 4. 命名为“S1–S4”的文件旨在厘清特定时间段内专利申请人与专利代理人之间的合作关系。通过该检索环节，可识别出与同一专利代理人存在合作的两名申请人，进而判断二者属于竞争对手还是合作方（即根据共同申请专利的可能性判定为共同权利人）。 5. 收录于“NGS Evolution”文件夹中的“E1–E8”系列文件，包含当前被公认为技术主流的四种核酸测序技术相关数据。此类文件旨在通过专利家族数量测算各技术的发展趋势并开展横向对比，同时如“NGS Evolution”文件夹中详述的那样，可根据各市场主体在四项技术上的投入程度识别相关参与者。
