Product-service systems (PSSs) have been the subject of numerous prior studies, most of which focus on presenting PSS strategies from a customer-centric perspective. This study offers a different approach to proposing new PSS strategies based on promising services that companies can implement using existing technology capability. First, business ecology networks consisting of goods and services are constructed using the trademarks of technology-based firms. Second, link prediction methods were applied to anticipate promising services. Third, patents were analyzed to determine whether the services can be developed using existing technology capabilities. Finally, a PSS portfolio map for establishing new PSS strategies for the target product is presented. Promising services and new PSS strategies are suggested according to whether they can be implemented using existing technology capability. A case study on wearable audio devices demonstrated the applicability and feasibility of the proposed approach. Indeed, promising services, such as self-reservation services and health and medical services, are suggested. A systematic approach and its quantitative outcomes are expected to have significant implications in practice as a support tool for decision-making regarding PSS strategy development. In addition, the proposed approach contributes to the existing literature by suggesting the broader use of intellectual properties.

产品服务系统 (PSS) 已成为众多先前研究的主题，其中大部分侧重于从以客户为中心的角度呈现 PSS 策略。这项研究提供了一种不同的方法，可以根据公司可以使用现有技术能力实施的有前途的服务来提出新的 PSS 战略。首先，利用技术型企业的商标构建商品和服务构成的商业生态网络。其次，应用链接预测方法来预测有前景的服务。第三，分析专利以确定是否可以使用现有技术能力开发服务。最后，展示了用于为目标产品建立新的 PSS 策略的 PSS 组合图。根据是否可以使用现有技术能力来实施，建议有前景的服务和新的 PSS 策略。可穿戴音频设备的案例研究证明了所提出方法的适用性和可行性。事实上，建议提供有前景的服务，例如自助预订服务和健康和医疗服务。系统方法及其定量结果有望在实践中产生重大影响，作为 PSS 战略制定决策的支持工具。此外，提议的方法通过建议更广泛地使用知识产权来促进现有文献。建议提供自助预订服务和健康医疗服务等。系统方法及其定量结果有望在实践中产生重大影响，作为 PSS 战略制定决策的支持工具。此外，提议的方法通过建议更广泛地使用知识产权来促进现有文献。建议提供自助预订服务和健康医疗服务等。系统方法及其定量结果有望在实践中产生重大影响，作为 PSS 战略制定决策的支持工具。此外，提议的方法通过建议更广泛地使用知识产权来促进现有文献。
