Analysis of collaborative robot technology patent map and research on development trends

This study conducts a systematic analysis of global patents in the field of collaborative robot technology based on applications and type of industry. The data analyzed derives from the PatSnap database covering 30,425 patents from 2006 to 2025, using explicit keywords such as "collaborative robot" to ensure specificity, with procedural filters and manual curation applied to maximize relevance and accuracy. The research focuses on patent application trends, technological hotspots, geographical distribution, as well as applicant and inventor analyses, providing a comprehensive overview of the innovation landscape and development trends in this domain. The findings indicate that collaborative robot technology has undergone three distinct phases: the initial emergence period, a phase of rapid growth, and a subsequent slowdown, and it is now transitioning into a stage of mature development. This apparent recent slowdown is significantly influenced by the standard 18-month lag in patent publication, meaning current data for the latest years is incomplete. Invention patents dominate the field, reflecting a high level of technological innovation. From a geographical perspective, the United States and China serve as the primary global innovation hubs, with their patent application volumes significantly surpassing those of other countries. In terms of applicants, multinational corporations such as Qualcomm, Intel, BRIGHT DATA LTD, and NVIDIA lead in patent filings, while emerging enterprises have demonstrated notable growth in patent applications, injecting new vitality into the industry. Furthermore, through patent citation analysis and market value assessment, this study identifies high-value patents and key technological areas, offering valuable insights for future technological advancements and market strategies. Based on these findings, the study proposes recommendations to further promote the sustainable development of collaborative robot technology, including strengthening technological innovation, optimizing market positioning, fostering emerging enterprises and talent, enhancing international cooperation, and aligning with policy directions.
