`
`REPORT AND RECOMMENDATION OF THE SPECIAL MASTER
`REGARDING UNITED STATES PATENT NOS. 5.941.972 and 6.425.035 B2
`
`Attached hereto is the Special Master's Report and Recommendation to United States
`
`District Judge Sam Sparks regarding the construction of claims in United States Patent Nos.
`
`5,941,972 ("the '972 patent") and 6,425,035 B2 ("the '035 patent").
`
`The Special Master notes that during the course of the pre-hearing and post-hearing
`
`briefing as well as the Markman hearing itself, the parties reached agreement on certain terms
`
`initially identified as being in dispute. For instance, the parties' stipulated definition of the claim
`
`term "native low level, block protocol," which is the same in both patents, was incorporated into
`
`their Stipulated Definitions of Claim Terms [#131], filed with the Court on August 31, 2004. Also,
`
`although Crossroads initially identified the term "remote storage devices" in the '035 patent as one
`
`of the terms requiring the Court's construction, it has apparently abandoned that position since the
`
`parties' dispute over the meaning of "remote storage devices" may be resolved by the Court's
`
`construction of the word "remote" without the need for a separate construction of the entire
`
`phrase.
`
`Additionally, in its post-hearing briefing, Crossroads stipulated to Dot Hill's definition of
`
`the term "allow access" in both patents based on the representations of Dot Hill's counsel at the
`
`hearing and in Dot Hill's briefing that the portion of Crossroads' proposed definition which was
`
`excluded by Dot Hill's definition- "preventing unauthorized communication"-is part of the
`
`definition of the phrase, "implementing access controls," which also appears in the patents. See
