I hope you don't mind me asking all these questions Jaco, but you're a knowledgeable chap :-). What was special about these yo-yos that could be patented? --Wilfred (talk|contribs) 06:25, 7 May 2006 (PDT)

• I don't quite know, since I haven't read the patent. I'll look it up since I'm wondering as well. (Hell of a lot of patents in the 1980's and 1990's for all kinds of yo-yo stuff...) --Jaco 07:27, 7 May 2006 (PDT)
