Trademarks generally reflect happenings in business and popular culture. For example, see my posts on “Shade of Grey”, “____ & CHILL“, Dak Prescott, Cecil the Lion, Polar Vortex, and more. USPTO filings generally reflect such trends in pop culture and sports. The latest example is fidget spinners.
If you have elementary school children, you are likely familiar with the recent “fidget spinner” craze sweeping through schools. Think Silly Bandz, Rainbow Loom, Zhu Zhu pets, and the like. For more, see the fidget spinner Wikipedia page.
In just the first 4 months of 2017, there have been at least 70 trademark applications featuring “fidget” or “spinner” in the name. In all of 2016 there were just 29 such filings! See images of TESS screenshot (search conducted May 1, 2017) below. This quite an increase in one quarter!
