Patent Law Amendment of 1984

Amends the patent laws to make it an infringement of patent to import into or sell in the United States without authority a product made in another country by a process patented in the United States. Makes it an infringement of patent to supply in the United States the material components of a patented invention for combination outside the United States, knowing that their combination in this country would constitute an infringement. Modifies the procedure for filing a patent application in a foreign country to eliminate the need for a license for modifications of explanatory information transmitted to or filed in a foreign country for patents on which no secrecy order has been issued. Eliminates criminal penalties for the failure to obtain a license for a patent application that is not subject to a secrecy order. States that prior art in the field of invention does not include unpublished information known to an inventor and therefore does not interfere with the patentability of that invention. States that priority of invention will be determined on the basis of affidavits and documents submitted to the Patent and Trademark Office rather than by discovery and deposition. Permits the use of arbitration in settling any disputes concerning patent interference. Insures the right of the licensor to receive royalty payments during the time such licensor's patent is under challenge, or to terminate the license at will.
