Judge Stark construes claims of patents relating to data encryption and decryption technology

Judge Leonard P. Stark recently construed six of seven disputed claim terms of U.S. Patent Nos. 7,136,995 and 7,900,057, entitled “Cryptographic Device” and “Cryptographic Serial ATA Apparatus and Method,” respectively. Enova Technology Corporation v. Initio Corporation, et al., C.A. No. 10-04-LPS (D. Del. Dec. 28, 2012). The following terms were construed:

-“encrypted” (and variations, including “encryption,” “encrypt,” “encrypting”)
-“passed through”
-“a data stream interceptor that distinguishes between command/control and data signal transfers”
-“transparently”
-“host”
-“said SATA protocol stack is operatively coupled to a USB (Universal Serial Bus) interface via a SATA-to-USB protocol translator”

The Court concluded that “cryptographic Serial ATA (SATA) apparatus” was not a claim limitation because it appeared in the preamble of claim 1 and did not "breath life" into dependent claims 13-15, as argued by Defendants. Id. at 9. Therefore, no construction was required. Id.
