Some light is thrown upon the extent of the publishing undertakings carried on at the time by Schöffer with his associate Hancquis, by the record of a suit brought by the two partners in 1480 against a certain Bernhard Inkus, of Frankfort. They charged Inkus with having begun the publication of a considerable series of books, the property right in which (_Eigentumsrecht_) vested in themselves and in Conrad Henki (who was a son of Fust). It does not appear from the record of this trial on what grounds Schöffer and his associates claimed the right to control these books, or whether the unauthorised issues of which they complained had been printed by the defendant Inkus or were simply being offered for sale by him on behalf of other printers. The case appears to have been referred or possibly appealed to a court in Basel, and by this court was issued some preliminary injunction against the continued sale of the books complained of. The record giving the final decision of the case is, however, missing. The lack of full details of the suit is the more to be regretted as it appears to have been the first case after the invention of printing involving, if not copyright ownership, at least a certain control by contract. In the same year we find the Magistracy of the City of Frankfort applying to the Magistracy of the City of Lübeck for the protection of Schöffer against some illegitimate infringement of Schöffer’s business rights on the part of the Lübeck citizen Hans Bitz. Here also is there no record as to the result of the application. The firm also had dealings with Ulm, as appears from a claim made, in 1481, for the collection of the moneys due from certain citizens in Ulm--Harscher, Ruwinger, and Ofener, for books delivered. They sent to Ulm, with a protection certificate given by Elector Diether of Mayence, a representative who was empowered to collect the money. There was at the outset some delay in connection with an alleged informality in his authorisation, but the Magistracy of Ulm sent back word that as soon as the requisite authorisation was secured, the collection of the money would be enforced in due course.
