Answer:
Harry was incorrect, and Samantha can be held liable for direct patent infringement
Step-by-step explanation:
In the court of law it is difficult to prove that Samantha did not know that the earlier patent existed. As, far as the court knows she made a comb which was identical to the one of the patent.
She would not be able to sell the rest of her inventory she would be held guilty of infringing the patent whether she had known or not known.
So, Harry's statement was wrong.
