We mentioned the scooter patent the other day and wondered along with others whether this meant the Honda Griffon was headed for production. One of our readers dropped a link in the comments pointing to this radial engine powered motorcycle patent and asked whether patents mean imminent production. A great question and it would seem the answer is patents mean no such thing, but my question addressing this particular patent is why it was granted in the first place. Radial engine powered motorcycles had already been built long before this patent was granted. What was different or special about this application that gives it some exclusive right to the design? Number of cylinders, perhaps? Interesting.
This patent application was filed July 14, 1999 and granted November 21, 2000, while the Redrup, for instance, was built as far back as 1919. There’s also the Megola which has the engine in the front wheel. Maybe I’m missing something and there is a reason this is unique but this patent application seems a little late to the party.
Great link, Tom! Thanks!
