The patent war rages on, especially among hi-tech companies. But, as firms like Google, Apple, Samsung and others batter each other, there is one old soldier in the tech industry that keeps piling up patents, adding to its already impressive portfolio. That company is IBM, and it recently added a new green cloud computing patent to its arsenal.
IBM consistently leads the nation in patents on a yearly basis. In 2012, the tech giant racked up 6,478 patents, which is a record. This marked the 20th straight year that IBM was the leader in patents, and it has totaled almost 67,000 patents in that time. This exceeds the total of Amazon, Apple, HP and Intel combined. In 2012, IBM’s next closest competitor in the space was Samsung, with 5,081 patents.
