America’s Big 5 tech companies increase patent filings, Microsoft holds lead in AI technologies
In terms of sheer numbers, in the CB Insights study, which curiously did not include patent giant and American research juggernaut IBM, Microsoft ranks supreme among this collection of five major tech firms. The Redmond, WA-based hardware and software developer has applied for a total of 16,840 patents over the seven years of the study. In second place is Google with 14,596 patent applications over the same time period. Although exact numbers for the other three firms weren’t publicly released by CB Insights, these two firms are followed by Apple (13,420 patent applications), Amazon (5,186) and Facebook (2,508), respectively. Collectively, these five companies have been pushing towards a total of 10,000 patent applications filed per year. This trend marks a sharp rise in patent application filing activities among the Big 5, which filed 3,565 patent applications collectively in 2009.
