6. Microsoft:

2,311 patents were awarded to this computing giant last year from the U.S., but this number is significantly diminished in comparison to how it has been doing in the past. In any case, the company’s consistent revenue coming in from its products- the Windows operating system, servers and Xbox game console, allows it to invest heavily in its R&D department.

5. Toshiba:

Another Japanese company, Toshiba is involved in a number of departments, ranging from consumer electronics to systems related to transportation and sewer infrastructure. It was granted 2,483 patents at the U.S. patent office last year, and has leaped in terms of number of patents it filed for technology.
