Yes, someone can still "steal" your idea even with a provisional patent because a provisional filing doesn't grant enforceable rights; it just reserves your priority date for a full (non-provisional) application, so you can only sue for infringement after your patent is granted, and you need to file the non-provisional within 12 months to secure your rights. While "patent pending" might deter some, a competitor could copy your product, but you'd have to wait for your full patent to get legal recourse, making it crucial to file the non-provisional and use Non-Disclosure Agreements (NDAs) for early talks.
