first the spacecowboy, now C3 and then Something.
Everybody’s got a metal rimmed yoyo coming out now,
makes me wonder why YYJ isn’t responding, is the patent dead?
Or are they thinking, naaaaaah, we’ve had it good for a few years?
There is a fairly recent thread on the topic already. I’m not particularly interested in the topic these days, but for those who are:
The space cowboy is the only one sold in the us that could infringe on the patent. All others are sold and manufactured in other countries where the patent does not affect them.

I’ve heard that the aluminum is like, a nano wider than the steel, so they got away with it.
Somebody said in another post it has to do with the bearing seat
Yep
Same goes for something. It’s aluminum on the outside and inside so it doesn’t infringe. The berserker does though.
As TA says, this has already been discussed extensively.
Let’s give it a rest.

Whoever said that should go back to the Zoo, voluntarily and just turn himself back in; before they find out he escaped again; to spread wild groundless nonsense on the Internet… Uh, in another thread, lol.
That’s like going to a Doctor for a neckache and he Schedules you for a Colonoscopy.
What does Yoyo ring attachment have to do with the Center of a Yoyo?

Read the patent carefully, very carefully. If you can think like a patent attorney you will understand the answer to your question…

A yo-yo comprising:
a pair of yo-yo body halves each formed as a composite having an inner hub, a central dish-shaped main body portion defining an inward facing surface and an annular-shaped peripheral body portion;
an axle threadably engaged at each end thereof into a hub thread formed into each said hub along an axis of rotation of said yo-yo;
each said hub including a shoulder radially adjacent said hub thread which, when said axle is fully tightened in frictional engagement into each said hub thread by tightening rotation between said body halves, bear against one another to define a minimum gap between said inward facing surfaces;
a bearing having an inner ring tightly frictionally engaged over each said shoulder, each end of said bearing extending into a recess formed into each said inward facing surface to maintain a tether in wrapped engagement around an outer ring of said bearing, said outer ring freely rotatable with respect to said body halves and said axle, said axle rotating with said body halves when said yo-yo is in use;
said axle, when said body halves are forcibly rotated in an axle disengaging direction one to another, causing a corresponding increase in the width of said gap;
each said inner facing surface arcuately shaped whereby said gap increases in width radially outwardly from said outer ring. -
A yo-yo as set forth in claim 1, further comprising:
an annular ground-engaging elastic ring extending around the surface of each said peripheral body portion, said elastic ring replaceable when worn and enhancing frictional contact with the ground and a user’s hand when said yo-yo is thrown. -
A yo-yo as set forth in claim 2, wherein:
each said peripheral body portion is formed of material having a density substantially greater than that of said main body portion to provide substantially increased rotational inertia of said yo-yo. -
A yo-yo as set forth in claim 3, wherein:
said peripheral body portions are spaced apart a distance substantially equal to a maximum width of said yo-yo. -
A yo-yo comprising:
a pair of yo-yo body halves each formed as a composite having an inner hub, a central dish-shaped main body portion defining an inward facing surface and an annular-shaped peripheral body portion;
an axle threadably engaged at each end thereof into a hub thread formed into each said hub along an axis of rotation of said yo-yo;
each said hub including a shoulder radially adjacent said hub thread which, when said axle is fully tightened in frictional engagement into each said hub thread by tightening rotation between said body halves, bear against one another to define a minimum gap between said inward facing surfaces;
a bearing having an inner ring tightly frictionally engaged over each said shoulder, each end of said bearing extending into a recess formed into each said inward facing surface to maintain a tether in wrapped engagement around an outer ring of said bearing, said outer ring freely rotatable with respect to said body halves and said axle, said axle rotating with said body halves when said yo-yo is in use;
said axle, when said body halves are forcibly rotated in an axle disengaging direction one to another, causing a corresponding increase in the width of said gap;
each said inner facing surface arcuately shaped whereby said gap increases in width radially outwardly from said outer ring;
each said peripheral body portion formed of material having a weight density substantially higher than that of said body halves. -
A yo-yo as set forth in claim 5, further comprising:
an annular ground-engaging elastic ring extending around the surface of each said peripheral body portion, said elastic ring replaceable when worn and enhancing frictional contact with the ground and a user’s hand when said yo-yo is thrown. -
A yo-yo as set forth in claim 6, wherein:
said peripheral body portions are spaced apart a distance substantially equal to a maximum width of said yo-yo. -
A yo-yo comprising:
a pair of yo-yo body halves each formed as a composite having an inner hub, a central dish-shaped main body portion defining an inward facing surface and an annular-shaped peripheral body portion;
an axle threadably engaged at each end thereof into a hub thread formed into each said hub along an axis of rotation of said yo-yo;
each said hub including a shoulder radially adjacent said hub thread which, when said axle is fully tightened in frictional engagement into each said hub thread by tightening rotation between said body halves, bear against one another to define a minimum gap between said inward facing surfaces;
a bearing having an inner ring tightly frictionally engaged over each said shoulder, each end of said bearing extending into a recess formed into each said inward facing surface to maintain a tether in wrapped engagement around an outer ring of said bearing, said outer ring freely rotatable with respect to said body halves and said axle, said axle rotating with said body halves when said yo-yo is in use;
said axle, when said body halves are forcibly rotated in an axle disengaging direction one to another, causing a corresponding increase in the width of said gap;
each said inner facing surface arcuately shaped whereby said gap increases in width radially outwardly from said outer ring;
an annular groove formed into each said inward facing surface radially adjacent to said recess, each said groove, cooperatively acting with a tether wrapped around said bearing outer ring to selectively connect said bearing outer ring with said body halves. -
A yo-yo as set forth in claim 8, further comprising:
an annular ground-engaging elastic ring extending around the surface of each said peripheral body portion, said elastic ring replaceable when worn and enhancing frictional contact with the ground and a user’s hand when said yo-yo is thrown. -
A yo-yo as set forth in claim 9, wherein:
each said peripheral body portion is formed of material having a density substantially greater than that of said main body portion to provide substantially increased rotational inertia of said yo-yo. -
A yo-yo as set forth in claim 10, wherein:
said peripheral body portions are spaced apart a distance substantially equal to a maximum width of said yo-yo.
Saying that the patent specified a type of bearing seat means at least one of the following must be true:
a. If the patent requires the yoyo to meet all specifications:
- The specified design only applies to plastic yoyos, and as such YYJ does not have a patent on metal yoyos with metal hubs
- Yoyos such as the SC infringe the patent (if their rims are on the far ends)
b. If the patent only requires the yoyo to meet either specification:
- The specified design only applies to plastic yoyos, and as such YYJ does not have a patent on metal yoyos with metal hubs
- All metal yoyos infringe the patent
c. If the patent only requires the yoyo to meet the specifications listed in the secondary bullets ie about rims:
- The patent covers both metal and plastic yoyos regardless of hub construction, and yoyos such as the SC infringe the patent (if their rims are on the far ends)
So is it like, if the bearing seat is aluminum, then the body is plastic, then the outer rim is aluminum, it doesn’t infringe because the main yoyo body is aluminum (bearing seat)?
This is a bunch of really long run-on sentences 
but seriously lets give this a rest guys
Hmm, the nearest Zoo is kinda far away… Does anyone have a bus ticket?
That’s how lawyers talk. Try reading your home or auto insurance policy sometime.
And yes, let’s give it a break.
From a PM I received today:
I’m answering it publicly so I don’t have to repeat it over and over.
First, I am not limiting the discussion, If I were this topic would be locked or deleted. I’m just tired of hearing about it over and over. Neither I nor anyone else here is privy to anything regarding this and the whole discussion here and in other related topics regarding this is purely based on uninformed speculation by people with an ax to grind who have no clue what it’s about, similar to the discussions regarding the Dif-E-Yo KK bearing. I am truly grateful to Frank for posting the info to clear that up and put it to bed.
It would be good if someone from YYJ would come forward and do likewise to forever put this to bed. Short of that, IFF you are a patent lawyer, please feel free to enlighten the unwashed. Otherwise, as I said before, give it a break.
The end…
