Re:Unbonded braces

[Subject Prev][Subject Next][Thread Prev][Thread Next]
We have used unbonded braces from the Nippon Steel Co.  I believe that they
were patented in both Japan and the US.  I think that recreating the system
would be a difficult task and you would not have the testing data to
support it's behavior.  Also, recreating any product based on someone
else's design might put you in violation of any number of patents.

Thanks for your comments.

Were the systems you used patented in the Japan or the US?  Or did you =
"re-create" the systems used.
