Abstract Prior-art search is a critical step towards determining whether a patent can be granted or not. In 2016, an internal project called Search Workflow Modelling (SWM) was launched at the European Patent Office (EPO) for building a search knowledgebase, which contains a set of models that record not only the current situation on how patent examiners deal with prior-art search (i.e. the as-is models), but also their requirements of being able to do a more efficient and effective search (i.e. the to-be models). We use the Fact-based Modelling (FBM) approach for formalizing search ontologies, which cover a common vocabulary, relations between concepts related to search, and constraints applicable to these relations. We use a hybrid modelling approach of Business Process Modelling Notations and Case Management Model and Notations (BPMN/CMMN) to model search work flows. A patent search strategy typically involves at least one FBM model and at least one BPMN/CMMN model. In this paper, we will illustrate 5 types of existing search strategies (including recursive flow patterns and FBM models for future search features), and future search strategies. The SWM empirical studies in this paper are being put into practice in the ongoing projects concerning search tools at the EPO.

欧洲专利局的检索策略

摘要 现有技术检索是决定是否授予专利的关键步骤。2016 年,欧洲专利局 (EPO) 启动了一个名为搜索工作流建模 (SWM) 的内部项目,用于构建搜索知识库,其中包含一组模型,不仅记录了专利审查员如何处理先验问题的现状。艺术搜索(即as-is模型),但也是他们能够进行更高效和有效搜索的要求(即to-be模型)。我们使用基于事实的建模 (FBM) 方法来形式化搜索本体,其中涵盖了公共词汇表、与搜索相关的概念之间的关系以及适用于这些关系的约束。我们使用业务流程建模符号和案例管理模型和符号 (BPMN/CMMN) 的混合建模方法来对搜索工作流进行建模。一项专利检索策略通常涉及至少一种 FBM 模型和至少一种 BPMN/CMMN 模型。在本文中,我们将说明 5 种现有的搜索策略(包括递归流模式和未来搜索特征的 FBM 模型),以及未来的搜索策略。本文中的 SWM 实证研究正在 EPO 正在进行的有关搜索工具的项目中付诸实践。以及未来的搜索策略。本文中的 SWM 实证研究正在 EPO 正在进行的有关搜索工具的项目中付诸实践。以及未来的搜索策略。本文中的 SWM 实证研究正在 EPO 正在进行的有关搜索工具的项目中付诸实践。
