In Response To: Re: Patents (Rod Tait)

Back in 1992 we had Don Currie show us a new rudder design. He gave me the demo jig to play with and I then returned it. A little later I re-figured what I'd seen and built the first one to be fitted to a kayak. A few months later he fitted one to one of his kayaks and we exchanged comments on a small modification that was needed. Another company also went into production with their version soon afterwards.

At no time was it patented, it was free to use the idea.

A decade later KajakSport patented their version. The patent was not for a good version at all and differs from their production model, the Navigator. I pointed out that two companies had been producing the idea for a decade in New Zealand. They said that's OK, keep on making them. A decade after that Sea-Lect "patented" the idea in USA. They had a list of features and when told those were the same as the 2 decade old design, a loud silence from them.

Here is the story and the design -

I believe the term "prior knowledge" covers the means of breaking a patent.

Incidentally, the T-bar trolley is produced in Germany (and other countries). That happened after I sent them the design in 1995. Theirs doesn't have legs because I didn't include those in the diagram I sent to them.
