Applying for a patent in one country using a patented invention beloning to some else from another country
<p>Let's assume certain invention is patented in country A, but not in B (in the latter it should be considered novel and non-obvious). Can a random person (not the original inventor) apply for and be granted a patent in country B on that same invention (thus prohibiting the inventor to produce/sell it in B)?</p>

<h2>No</h2>
<p>Because it’s patented in country A, it is not novel anywhere in the world. That is, the patent in country A is “prior art” that would disqualify it from being patented anywhere else.</p>
<p>The original patent holder can patent it elsewhere because patent law has an exception for that.</p>

<p><strong>No</strong></p>
<p>Only true inventors can apply for a patent. If it was not patented in country A or anywhere, a random person who is not the inventor still can't patent it anywhere.</p>
<p>In practice, of course someone could lie on the oath and be granted a patent.</p>
