    When did the R in a circle trademark symbol become used? I haven't found any information on that.

    Ha - I have been wondering the same thing myself!

    I seem to recall that Reg. U.S. Pat. Off. was used up until about 1947 but I can't confirm that and I can't remember where I learned that.

    PS. I love your avatar - that pink nose is too much!
