Neither of those two instances related to patentable subject matter or was 
adopted in the enacted statute.  The first proposed departure from the English practice 
was a novelty provision protecting the inventor against those who derived their 
knowledge of the invention from the true inventor; the second was in a requirement that 
patentees make a “Public Advertisement” of their invention.  Such a requirement was 
thought necessary “in so extensive a Country as the United States.”  Senate Report, 
reprinted in 22 J. Pat. Off. Soc’y at 363-64.   
The American statute ultimately differed in some other respects.  For example, 
Congress rejected the English rule that the invention need only be novel in England.   
The American statute required novelty against the whole world and did not permit 
“patents of importation.”  See To Promote the Progress, supra n.4 at 95-97, 137-38.
