I don't think so my friend because the font selection,color scheme of the logo type of the logo, style are way different from each other for both logos if you search on internet you will find thousands of logo with similar color scheme what does that mean ?? They all copied from each other hmm !!! No my friend they all inspired from each other some how and creates a newer version.
