The best way to protect original content is to build a lot of links to it, so it gets indexed by Google asap and and you're credited authorship. Using good schema helps as well, and the more realistic you can make the article the better (give your articles an author with a profile image, link to an author page, have a realistic author page with social links like the author's linkedin, FB and other socials). But at the very least, build enough backlinks so it shows up on SERPs for your brand keyword asap.
