Can I apply for a military technology patent?

Of course. Involving national defense security or vital national interests, it can be applied as a national defense patent or a confidential patent, in which the national defense patent needs to be applied to the national defense patent agency and the confidential patent needs to be applied to the Patent Office. If it does not involve national defense security or major national interests, it can be used as an ordinary patent application. Communicate if you have any questions.
