"You agree that access to the Support Portal, including access to the service request function, will be granted only to your designated support contacts and that the Materials may be used only in support of your authorized use of the Oracle product and/or cloud services for which you have a current support contract. Except as specifically provided in your agreement with Oracle, the Materials may not be used to provide services for or to third parties and may not be shared with or accessed by third parties."
Where it gets murky is the situation you've described, where you pick up knowledge in the course of your authorised access that happens to be helpful to a third party sometime in the future. My guess would be that saying "oh hey, I have a downloaded copy of a support article that might come in handy here" is out, but saying "I've hit this problem before and I remember what the fix was" is ok - unless Oracle want to claim they own the part of your brain holding their content, of course...
It sounds like the behaviour described in the article, offering patches you've written yourself without access to licensed support material, is quite different from what they're squabbling about in the lawsuit. Whether it contravenes some other license clause is a whole separate question.
