Judge Stark Construes Additional Claim Terms at Defendants’ Request

Judge Leonard Stark has issued a supplemental claim construction order in a patent infringement case filed by Enova Technology against various manufacturers of hard drives and related encryption technologies. See Enova Tech. Corp. v. Initio Corp., C.A. No. 10-04-LPS, Order (D. Del. Feb. 19, 2013). We previously reported on Judge Stark’s original claim construction order. Now with trial approaching, Judge Stark has considered the defendants’ request for additional construction, including construction of several broader claim terms that include within them narrower claim terms previously construed. After construing the terms in question, he cancelled the scheduled claim construction hearing and advised the parties that trial would begin in its place.

Judge Stark construed the following additional terms:
– “main controller”
– “a main controller receiving input from said at least one data stream interceptor and determining whether incoming data would be encrypted, decrypted or passed through based on the received input from said at least one data stream interceptor”
– “SATA protocol stack”
Judge Stark also found that the following additional terms did not require any construction:
– “data stream interceptor”
– “main controller”
– “data generating controller”
– “data storage controller”
– “cipher engine”
– “FIS (Fram Information Structure)”
– “cryptographic engine . . . for encrypting and decrypting at least a subset of data FISes (Frame Information Structures) communicated to or from the SATA protocol stack”
– “the main controller configured to cause . . . the SATA protocol stack to process a Register-Device to Host FIS [without decryption responsive to receiving the Register-Device to Host FIS from the interface of the device]”
