Patent granted in India to TELEFONAKTIEBOLAGET L M ERICSSON
Patent number 374151 has been granted to TELEFONAKTIEBOLAGET L M ERICSSON which is titled DATA DISTRIBUTION/RETRIEVAL USING MULTI DIMENSIONAL INDEX. The primary independent claim of this patent states a method of data distribution in a distributed data storage system that stores a set of data items across physically distinct computers. Each physically distinct computer manages a subset of the data items by defining at least one metric space associated with the distributed data storage system and within the one metric space a number of hyper-spheres are defined wherein each of the defined hyper-spheres have a center and radius, data points representing corresponding data items, and an association with one or more of the physically distinct computers. The patent applicant responded to this objection by stating that if the present invention provides a technical solution to a technical problem and has a technical effect then the same cannot be considered to fall under the category of algorithm or computer program per se. This patent falls under the category of Computer Science. Overall, this patent covers a distributed data storage system that uses a data distribution and location algorithm based on distance functions and hyper-spheres in a multi-dimensional space.
