Vorwerk Assigned Patent

Vorwerk & Co. Interholding GmbH, Wuppertal, Germany, has been assigned a patent (9,521,002) developed by Greive, Volker, Wuppertal, Germany, for a “method for copy-protected storage of information on a data carrier.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for storing digital data information on a data carrier and for reading the information therefrom uses a disk having an individual digital identifier. A signature is formed, and the information includes information items, which can be processed by a first electronic data processing device only if the identifier and the signature are in a predefined relation to one another. To supply a household appliance operated by an electric motor with process control data, while ensuring that only original data are used, the information components can be processed by a second electronic data processing device even if the signature and the identifier are not in the predefined relation to one another. Also, a household appliance operable by an electric motor, in particular a food processor, has an electronic data processing device. A system and an integrated semiconductor circuit also realize the features for storing digital data information.“

The patent application was filed on May 7, 2014 (14/271,636).
