There is 2 manufactories in China, 1 in Germany and 1 in Japan. The 2 in China has date back over a year or two already....
The patent rights to these "poly balls" does not belong to the manufactory
There was a delay/dispute in manufactoring regarding patent rights, but that got nothing to do with the amount of poly ball equip manufactories - which is increasing in numbers since 1 July 2014 already.
How ITTF Poly Ball approval works is that the manufactory will get 3 Star balls approved.
Then brands will design the label to be used on these 3 star approved balls. Then the "complete" balls will be approved by ITTF
From theory, all balls from the same factory should be the same, as the factories only have 1 set of approved balls (unless they have many sets - where the chance is slim). As I know, only 1 manufactory has the technology to make seamless
There was an ITTF presentation made few months ago regarding the above. I'm sure it is searchable on the internet
