Owen J. Roberts, Hoover Company v. Coe — Opinion of the Court
“ Thus it is clear that throughout more than a century Congress has for correction of erroneous adverse rulings, which if unreversed would end the proceedings in the Patent Office, preserved the remedy by bill in a district court either as additional to or alternative to that by summary appeal and has made the effect of adjudication in equity the same as that of decision on appeal. ”
