Dear Arpad,

Recently, a question arose regarding the adequacy of a provisional patent application, filed in accordance with section 111(b) of title 35, United States Code, to serve as the basis for the right of priority provided by Article 4 of the Paris Convention for the Protection of Industrial Property.

Although we are convinced that such an application is indeed sufficient for this purpose, we would be very interested in your opinion on this subject and request a reply at your earliest convenience.
