【摘要】 提出一种以专利群为对象，功能需求为规避依据，可拓理论为理论工具的规避设计方法。以产品在线评论为需求获取资源，利用自然语言处理技术与可拓基元模型将其转化为若干功能需求；利用在线评论关键词与IPC(International Patent Classification)分类号一同检索目标专利，分析各专利文本后将其整合构建专利群功能模型；将所得功能需求与专利群功能模型进行功能匹配，从而确认待规避内容。然后，以功能需求为导向，可拓分析为路径进行规避分析，利用可拓变换进行规避求解操作，并对所得新方案进行技术特征侵权判定。最后，以一药品收纳盒专利群为案例，验证上述流程对于专利群规避设计的可行性。将功能需求作为规避依据，有助于在专利群规避过程中降低确认待规避内容时的主观判断影响，同时保证后续规避方案求解朝着满足用户的功能需求的方向开展。更多还原

【Abstract】 In this paper, a circumvention design method which taking patent group as target, function requirement as the basis for circumvention and the extension theory as the theoretical tool was proposed. Firstly, online product reviews were used as requirement acquisition resources, which were transformed into several functional requirements by using natural language processing technology and extension primitive model. Secondly, the target patent group was researched by the keywords from the online reviews and IPC classification code, then the patent group function model was built by analyzing each patent text. Thirdly, the obtained function requirements were matched with the patent group function model to confirm the contents in patent group function model to be circumvented. Fourthly, the function requirements were guided by the extension analysis as the path for circumvention analysis, and the extension transformation was used to express the circumvention solution operation,then the new scheme was determined whether exists the technical features of infringement. Finally, a medicine storage box patent group was taken as case study to confirm the feasibility of the above process of patent group circumvention design. Taking functional requirements as the basis for circumvention can help reduce the influence of subjective judgment in confirming the content to be circumvented in the process of patent group circumvention,and at the same time ensure that the subsequent circumvention solution is carried out in the direction of satisfying users’ function requirements.更多还原
