The GXR has been proven to be a marketing failure, as I predicted at the very beginning. Well, can you still see it at the streets? :-)

I don't know what the requirements are and neither do you.
Some companies build products for a long time without applying for a patent because they expect to keep the process secret longer than a patent would last.
Good bye.

Usually it is just not worth it to start building prototypes - it is waste of enginering resources, especially if the invention is non-trivial, maybe requiring highly advanced technologies to be used, maybe even more developement of some basic requirements of the machine before (or if) it can actually be built.

Especially in the old days it would have ben impossible to drag the prototype of the steam engine, or ships propellor or whatever to the patent office 500km away.

Evidently in the US before 1880, a prototype was required. However, this was not the case in at least some of the european countries.
Today (in the US) no prototypes required.
