“ This Court has recently declared that one who sues in a federal court of equity to enjoin the infringement of his patent, thereby submits himself to the jurisdiction of the court with respect to all the issues of the case, including those pertaining to a counterclaim praying that he be restrained from infringing a patent of the defendant. ”

“ They argue that a counterclaim for patent infringement cannot be maintained over plaintiffs' objection if it does not contain allegations showing that plaintiffs are inhabitants of or committed acts of infringement and have a regular place of business within the district in which they commenced their suit. ”

“ Petitioners, New York corporations having their principal offices in that state, brought this suit in the northern district of Ohio against defendants, two corporations having regular and established places of business in that district and two individuals residing there. ”
