"developing a comprehensive strategy to produce"
"The smoking gun in Shimano's application can be found in the details. The abstract drawings depict a concept that is near production"
"Shimano's application also describes in detail, a special lubricating fluid... Does that sound speculative? I didn't get that impression either."
"this gearbox will eventually be scalable and thus appear at a number of price points. Conventional gearboxes are not - which is why the gearbox bike has never been moved into mass production."
I wouldn't take Shimano patent filings as any kind of guide to what they will actually produce, they are well known for patenting everything they think of as a protective policy just in case somebody else finds a way to bring the idea to the market in a profitable way which has escaped the Shimano production engineers.
