Daniel O. Kutz的研究兴趣在于社会情报学、交互设计,以及信息可视化。他与情报学家Katy Börner和平面设计师Elisha F. Hardy合作,共同开发了特色地图从视觉上理解和沟通不同专利持有人的专利空间的知识覆盖面和演化情况。在1976年1月1日到2002年12月31日之间授权的专利从美国专利商标局(United States Patent and Trademark Office ,简称USPTO)的专利存档中获取。一个简单的图表现了在过去25年中专利授权的数量增长了140%。250万个专利通过分类进一步分组,并研究其时隔五年后每个类的专利数量的变化。利用由马里兰大学人机交互实验室开发的空间填充技术树图来描述和对比了增长缓慢或快速的类。为了对比苹果电脑公司和私人专利持有人的专利控股演变,树图以时间序列排列。以分类等级的纵向对比变得可能,揭示了专利权人过去和现在的知识边界、专利行为,甚至可能是对研究和开发趋势的整体理解。
