Top 10 Key Players companies in Time dilation
by Highest Patent Value in the Japan in 2020

The Time dilation top 10 is Discovery PatSnap’ annual ranking of the top 10 Highest Patent Value Time dilation Key Players in the Japan. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2020, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Time dilation is a difference in the elapsed time measured by two clocks, either due to them having a velocity relative to each other, or by there being a gravitational potential difference between their locations. After compensating for varying signal delays due to the changing distance between an observer and a moving clock (i.e. Doppler effect), the observer will measure the moving clock as ticking slower than a clock that is at rest in the observer's own reference frame. A clock that is close to a massive body (and which therefore is at lower gravitational potential) will record less elapsed time than a clock situated further from the said massive body (and which is at a higher gravitational potential).
