Custom
From YoYo Wiki
In the height of the yo-yo boom in the late 1990's Custom was sued by Playmaxx/Proyo for infringing upon the Playmaxx brake pad patent. The alledgedly infringing system was developed by Eric Wolff, who had modified a fixed-axle Reactor into a ball-bearing axle with friction rings made from a Rubbermaid no-slip bathtub tread strip. Eric's design was incorporated into a re-designed Reactor, the Chain Reactor, and eventually, all of Custom's ball-bearing axle yo-yos.
After a judge ruled against Custom, they reached a settlement with Playmaxx agreeing to redesign their friction rings.
The Playmaxx Cold Fusion was actually manufactured by Custom for Playmaxx and all Cold Fusion parts both finished and unfinished had to be turned over to Playmaxx as part of the settlement. It is these Cold Fusion parts that were acquired by Duncan when Duncan purchased Playmaxx and once this supply of parts was exhausted, the Cold Fusion was retired by Duncan.
