Quantum vs. Overland Storage

繼Overland Storag於2012.6.28.對Quantum Corporation提起專利侵權之訴後，Quantum也在2013.4.12.在加州南區聯邦地方法院對Overland Storage祭出侵權訴訟。
本案的系爭專利為US7,263,596，專利名稱為：資料儲存應用的邏輯程式館架構以及使用方法(Logical library architecture for data storage applications and methods of use)，其技術為一種提供各主機間與資料存取來源間的間接位準的系統與方法，其形態可比擬為一般的可裝卸式資料存取裝置。在數部主電腦(host computers)中，該專利方法可透過資料儲存來源(data storage resources)，將邏輯位址(logical address)連接到實際存放在主機中的物理位址(physical address)，資料儲存資源柄(data storage resource handle)或邏輯代理伺服器(logical proxy)被提交到主機中，由主機的管理層決定要接收物理資訊儲存來源，或者是虛擬的儲存來源。

Title : Logical library architecture for data storage applications and methods of use
Filing Date : 2003.12.17.
Issue Date : 2007.8.28.
Abstract :
Systems and associated methods provide a level of indirection between multiple host computers and multiple data storage resources, such as removable media data storage devices. At least one of the hosts is not provided with direct access to some of the removable media data storage devices. Instead, logical addresses are provided to the host computers, where the logical addresses can relate to physical addresses associated with the data storage resources. A data storage resource handle or logical proxy may be presented to a host, and a management layer determines whether the host receives access to physical data storage resources, or virtual resources that emulate the physical resources.
