Abstract One of the most crucial tasks in patent analysis concerns valuating patents as intellectual properties which embody financial assets, and yield license fees or even competitive advantages. There are several approaches that deal with finding indicators of a patent's value, some in terms of patent scope. So far, the available work is incomplete in various respects. Overcoming deficits caused by an insufficient use of bibliometric indicators, this paper provides a normalized technological patent scope indicator through a semantic patent analysis of patent claims. By providing regressions between the patent scope and several indicators, this paper shows that the patent scope in the case of the three technologies DVD, HD-DVD and Blu-ray disc, follows several theories of prior work. This work tackles theoretical implications, as it manages to operationalize Knight's theory (hash mark analogy of broad and narrow patent claims) by a data driven approach and enhances recent work by means of a normalized semantic patent scope, based on patent claims instead of bibliometric data. Finally, managers may profit from a higher resolution regarding decision making for competitor analysis and M&A-questions, as this new indicator describes how broadly assignees define their technologies semantically, thereby offering a source for a patent's value.

通过专利权利要求的语义分析衡量技术专利范围——专利评估指标

摘要 专利分析中最关键的任务之一是将专利评估为体现金融资产、产生许可费甚至竞争优势的知识产权。有几种方法可以用来寻找专利价值的指标，有些是根据专利范围。到目前为止，可用的工作在各个方面都是不完整的。克服文献计量指标使用不足造成的不足，本文通过专利权利要求的语义专利分析，提供规范化的技术专利范围指标。通过提供专利范围和几个指标之间的回归，本文表明在 DVD、HD-DVD 和蓝光光盘三种技术的情况下，专利范围遵循先前工作的几个理论。这项工作解决了理论意义，因为它设法通过数据驱动的方法实施 Knight 的理论（宽泛和窄幅专利权利要求的哈希标记类比），并通过规范化的语义专利范围来增强最近的工作，基于专利权利要求而不是文献计量数据。最后，管理人员可以从关于竞争对手分析和并购问题的决策制定的更高分辨率中受益，因为这个新指标描述了受让人在语义上定义他们的技术的范围，从而提供了专利价值的来源。
