Abstract

ABSTRACT This study captures the origin and pattern of foreign knowledge inflows to the Indian IT services industry using patent citation data. It examines the patterns of backward patent citations by the US origin and non-US origin foreign IT services firms operating in India using the USPTO patent citation data from 2013 to 2017. To analyze the citing patterns of firms, we classified backward citations into two categories: self-citations and non-self-citations. Our study finds that patents granted to the US origin firms hold a relatively higher number of backward citations and a higher average number of inventors. It indicates that the Indian IT services industry receives more complex technology inflows from the US origin firms compared to non-US origin firms. It also shows a positive relationship between self-citations and lowers patent grant lag. Further, this study suggests that more self-citations by the US origin firms reinforce more patents that develop a patent cycle for a firm. Therefore, the US origin firms in the Indian IT services industry dominate in patenting activities at USPTO.

外国公司的专利引用模式——对印度IT服务业的分析

摘要本研究利用专利引用数据，捕捉了外国知识流入印度IT服务业的来源和模式。它使用美国专利局2013年至2017年的专利引用数据，研究了在印度运营的美国来源和非美国来源外国It服务公司的反向专利引用模式。为了分析企业的引用模式，我们将反向引用分为两类：自我引用和非自我引用。我们的研究发现，授予美国本土公司的专利拥有相对较高的反向引用次数和较高的平均发明人数量。这表明，与非美国本土公司相比，印度It服务业从美国本土公司获得的技术流入更为复杂。它还显示了自我引用和降低专利授予滞后之间的积极关系。此外，这项研究表明，美国本土公司更多的自我引用强化了更多的专利，从而为公司制定了专利周期。因此，印度IT服务行业的美国本土公司在USPTO的专利申请活动中占据主导地位。
