Abstract:There are some gaps in the existing research on enterprise intellectual property management capability, such as the lack of operability of the promotion path and the focus of work. This paper introduces the capability maturity model, and proposes the enterprise intellectual property management maturity model (IPM-CMM) based on five dimensions of strategy, talent, information, organization and culture, including three sub models: grade model, evaluation model and promotion model, then use this model to compare the intellectual property management capabilities of Huawei Technologies Co., Ltd., Lenovo Holdings Co., Ltd., and Xuzhou Construction Machinery Group Co., Ltd. (XCMG).The result shows that Huawei is at a high level of the continuous optimization class, but should strengthen the dominance of intellectual property culture; Lenovo is at a high level of the quantitative management class, but should focus on increasing the quantity and quality of self-created intellectual property; XCMG is at the upper middle level of the standardized management class, with all dimensions requiring improvement. Theoretical and case studies demonstrate that IPM-CMM can serve as a guiding framework for continuous improvement of the enterprise intellectual property management capability; in the specific application of this model, it is necessary to perform well in the formation of the evaluation team, the collection of evaluation data, and the analysis of the evaluation results.
