SCG POWER RANGERS LLC sent an application for trademark of Power Rider in July of 2011, it was granted in September. Then they filed extension and it was granted in May of 2012. April of 2013 it was approved for a second extension. But nothing has happened with it. What is the difference between Copyright and Trademark?
The purpose of a copyright is to protect works of authorship as fixed in a tangible form of expression. The registration processes of copyright and trademark are entirely different. For copyright the filing fee is small, the time to obtain registration is short. For trademark the filing fee is larger, the time to obtain registration is much longer and examination by the Trademark Office. The purpose of a trademark is to protect words, phrases and logos used in federally regulated commerce to identify the source of goods and/or services.
Many fans think that Power Rider has to do with Kamen Rider, which is also made by Toei like Super Sentai. Saban adapted Kamen Rider Black RX into Masked Rider in 1995. Adness Entertainment adapted Kamen Rider Ryuki (2002) into Kamen Rider Dragon Knight in 2009. Many fans want Kamen Rider Fourze (2012) to be adapted into Power Rider. But maybe Power Rider is something else or just a trademark to get one 'just cause.'
