提出了一种基于专利引证密度的专利丛探测方法，寻找专利池中的专利引证密度黑洞，验证专利池与专利丛共存的必然性，并以此证明专利池存在的必要性，消除专利池技术垄断的嫌疑。从1394专利池中采集了64个美国专利，从美国国家经济研究局的专利数据集中采集了135条专利引证数据，利用Pajek构建专利引证网络。结果表明：1394专利池中存在一个黑洞，其专利引证高度密集，且明显高于周边；黑洞内部各项专利在权利保护范围上均存在一定的交集，应该是高速传输数字接口领域的一个专利丛。

This article proposes a method of patent thicket detection based on patent citation density, looking for a black hole of patent ci-tation density in a patent pool. The aim is to verify the inevitability of the coexistence of a patent thicket and a patent pool, prove the ne-cessity of the existence of a patent pool, and then eliminate the technological monopoly suspicion of a patent pool. This article collects six-ty-four American patents from the 1394 patent pool, and extracts one hundred and thirty-five patent citations from the dataset of the Na-tional Bureau of Economic Research, and then builds a patent citation network with the help of Pajek. The results show that: there is a black hole existing in the 1394 patent pool, whose patent citations are highly populated, and significantly higher than the surrounding;the rights protection ranges of patents within this black hole have intersections. So it should be a patent thicket in the field of high-speed trans-fer digital interface.
