Foreign nationals residing in the United States are steadily making greater contributions to the country's intellectual property, stirring concern about maintaining the country's competitiveness and the debate over whether to relax U.S. immigration policy.
Research released Wednesday shows that foreign nationals were listed as inventors or co-inventors in 25.6 percent of patent applications from the U.S. in 2006, up from 7.6 percent in 1998.
The data, from the World Intellectual Property Organization, was gathered by academics from Duke, Harvard and New York University. The study defines foreign nationals as individuals with foreign citizenship living and working in the States.
Technology hubs such as California, Massachusetts, and New Jersey claimed the highest rate of foreign national patent applications.
The report also shows that foreign nationals were named in more than half of international patent applications filed from the U.S. by large corporations.
Those include Qualcomm, at 72 percent; Merck, at 65 percent; General Electric, at 64 percent; Siemens, at 63 percent; and Cisco, at 60 percent.
