There are very few original ideas, and you'll just drive yourself and everyone around you crazy by fretting over originality. Don't fool yourself into believing that only Chinese companies are interested in ripping off ideas; this has been a major function of large companies for a very long time.

We have to pop the fairytale bubble that some of us live in. Marketing and sales will win the day. No matter how fancy your technology is, there will be competitors and rivals, and it won't really matter who was "first". Being first can, in fact, be a substantial disadvantage, since you don't have the response/feedback from a competitor's prior attempt to gauge and reference.
