From what I understand, Oracle sued a company who was providing technical support to Oracle customers related to Oracle products. The reason they sued was because Rimini appeared to be a competitor in one business area, however the latter was still promoting Oracle and was involved with them. I see no reason why a partnership could not have been struck to deal with this. Oracle could have sold the rights to Rimini and eventually both would have benefitted. There must have been a gap in the market which prompted Rimini to enter.
