Of course, when you start to manufacture your invention, your competition will see it and can legally copy it until your patent issues. Even if you don’t show your invention but you file an application, it’ll be published 18 months after filing unless you give up all rights to file abroad. In conclusion, it is critical to take necessary precautions when sharing your invention with others. By doing so, you can protect your intellectual property rights and ensure that your invention remains safe from theft or copying. If you have more questions about this topic, I suggest consulting with an experienced patent attorney.
