No patent issued by the Patent Office (PTO) is secure and getting patents is time consuming and costly, especially for individuals. Far from securing patents, the PTO unsecures them under an unconstitutional presumption of validity and makes them tickets to federal courts. Here as example, I give a detailed summary of patent case Constant vs AMD. The decision in that case was made in the absence of jurisdiction, not justified on merits, and in fraud of the administration of justice.
