About occy rings and dual leech rings

Well, I'm thinking about trading for an occy ring and dual leech rings with mf. I was wondering if these items will go poof after the new patch comes out. I'm concerned with the fact that they can be duped, so will these items disappear regardless or only when I join a game that has the original? Also because these items are bugged will they disappear?
I'm also thinking about investing in ith 180% mf ccb or pb will this be worth it?
I've heart that sojs don't have an item code, that's why they can be duped and won't disappear. Does this statement hold true, and if it is true will the same concept apply on other rings as well?

I'm sorry about bombarding you guys with these questions, I might have been redundant in asking the same question someone else might have previously... but I've only seen the thread on ith items, and I just wanted to make sure once again before I traded away my precious sojs that took me so long to gather... I thank you for your time and your guidance.
