Bedrock Computer Technologies, LLC v. Softlayer Technologies, Inc. et al Doc. 347 Att. 8 EXHIBIT 6 Dockets.Justia.com Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 1 of 16 IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF TEXAS TYLER DIVISION BEDROCK COMPUTER, TECHNOLOGIES, LLC v. SOFTLAYER TECHNOLOGIES, INC., ET AL. § § § § § § § No. 6:09cv269 LED-JDL JURY DEMANDED ORDER This provisional claim construction Order sets forth the Court's initial constructions for the disputed claim terms in U.S. Patent No. 5,893,120 ("the `120 patent"), asserted by Plaintiff Bedrock Computer Technologies, LLC ("Bedrock"). The Court will issue a Memorandum Opinion and Order, including a full analysis of the disputed claim terms, at a later date. The Court may modify these provisional constructions when it issues the Memorandum Opinion and Order. This Order is intended to serve as a guideline and framework with which the parties may proceed at an earlier point in the litigation. BACKGROUND Bedrock alleges Softlayer Technologies, Inc., Citiware Technology Solutions, LLC, Google, Inc., Yahoo! Inc., MySpace Inc., Amazon.com Inc., Match.com, Inc., and AOL Inc.1 (collectively, "Defendants") infringe the `120 patent. The parties have presented their claim construction positions (Doc. Nos. 275, 284 & 300). On October 7, 2010, the Court held a claim construction hearing and heard argument. 1 Defendants CME Group Inc. and PayPal, Inc. settled earlier in the litigation. See (Doc. Nos. 168 and 2 0 2 ). Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 2 of 16 DISCUSSION I. "a linked list to store and provide access to records"2 Defendants' Proposed Construction Two or more records in which each record contains a pointer to the next record in the list or information indicating that there is no next record. Plaintiff's Proposed Construction A list in which each record contains a pointer to the next record or information indicating that there is no next record. The parties have agreed to the construction of this term at the October 7, 2010 claim construction hearing and the Court provisionally adopts the agreed construction, "a list, capable of containing two or more records, in which each record contains a pointer to the next record or information indicating there is no next record." II. "automatically expiring"/ "expired"3 Defendants' Proposed Construction Becoming obsolete and no longer needed or desired in the storage system by comparing some portion of the contents of the record to some external condition / obsolete and no longer needed or desired in the storage system because of some external condition Plaintiff's Proposed Construction After a limited period of time or after the occurrence of some event, becoming obsolete and therefore no longer needed or desired in the storage system / obsolete and therefore no longer needed or desired in the storage system The Court provisionally construes "automatically expiring" as, "becoming obsolete and therefore no longer needed or desired in the storage system because of some condition, event, or period of time." The Court finds that internal and external events and conditions are encompassed by the construction. 2 The term "a linked list to store and provide access to records" is contained in claims 1 and 3. Claims 5 a n d 7 discuss a "linked list of records." The provisional construction applies to claims 1, 3, 5, and 7. 3 This term is contained in claims 1, 3, 5, and 7. 2 Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 3 of 16 In addition, the Court provisionally construes "expired" as, "obsolete and therefore no longer needed or desired in the storage system because of some condition, event, or period of time." Again, internal and external events and conditions are encompassed by the construction. III. "removing . . . from the linked list"4 Plaintiff's Proposed Construction Bedrock believes that this term language is properly construed pursuant to 35 U.S.C. § 112(6)5 no construction necessary; however, should the Court construe this term; "removing at least some of the automatically expiring records from the linked list when the linked list is accessed for a purpose other than garbage collection, using the same linked list traversal performed for the purpose other than garbage collection." 6 Defendants' Proposed Construction While traversing the linked list, both adjusting the pointers in the linked list to bypass the previously identified expired records and deallocating the memory occupied by these records The Court finds the proper construction of the term "removing . . . from the linked list" is "adjusting the pointer in the linked list to bypass the previously identified expired records." IV. "dynamically determining"7 The parties dispute the phrase "identifying and removing at least some of the expired ones of the records fr o m the linked list when the linked list is accessed." The Court chooses to define certain terms within the disputed p h r a s e . The term the Court chooses to construe is contained in claims 1, 3, 5, and 7. Each of the claims differs s lig h tly as to what is removed from the linked list, but the issue concerns what the removal step entails. 5 4 Bedrock's proposed construction applies to claims 1 and 5. This proposed construction applies to claims 3 and 7. 6 This term is contained in claims 2, 4, 6, and 8. The parties dispute the phrase, "dynamically determining a m a x im u m number of expired ones of the records to remove when the linked list is accessed." The Court chooses to d e fin e certain terms within the disputed phrase separately. 7 3 Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 4 of 16 Plaintiff's Proposed Construction Bedrock believes that this term language is properly construed pursuant to 35 U.S.C. § 112(6)8 Determining, during the program execution, maximum number of expired ones of the records to remove when the linked list is accessed9 Defendants' Proposed Construction Immediately before the linked list is traversed, determining a single number that serves as an upper limit on the number of records to remove while the linked list is traversed The Court finds the term "dynamically determining" means "making a decision based on factors internal or external to the information storage and retrieval system." V. "maximum number"10 Plaintiff's Proposed Construction Bedrock believes that this term language is properly construed pursuant to 35 U.S.C. § 112(6)11 Determining, during the program execution, maximum number of expired ones of the records to remove when the linked list is accessed12 Defendants' Proposed Construction Immediately before the linked list is traversed, determining a single number that serves as an upper limit on the number of records to remove while the linked list is traversed The Court finds that no construction is necessary for the term "maximum number." The Court, however, does find that the term "maximum number" is not limited to a single number. 8 Bedrock's proposed construction applies to claims 2 and 6. This proposed construction applies to claims 4 and 8. 9 This term is contained in claims 2, 4, 6, and 8. The parties disputed the phrase, "dynamically d e te r m in in g a maximum number of expired ones of the records to remove when the linked list is accessed." The C o u r t chooses to define certain terms within the disputed phrase separately. 11 10 Bedrock's proposed construction applies to claims 2 and 6. This proposed construction applies to claims 4 and 8. 12 4 Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 5 of 16 VI. "external chaining" The parties have agreed that the term "external chaining" means "a technique for resolving hash collisions using a linked list(s). VII. "when the linked list is accessed"13 and Ordering of Method Steps14 Claim Term or Phrase when the linked list is accessed Plaintiff's Proposed Construction Bedrock believes that this term language is properly construed pursuant to 35 U.S.C. § 112(6)15 No construction necessary16 Defendants' Proposed Construction Both identification and removal of the automatically expired record(s) occurs during the same traversal of the linked list. 13 This term is contained in claims 1, 3, 4, 5, 7, and 8. The Ordering of Method Steps applies to claims 3 and 7. Bedrock's proposed construction applies to claims 1 and 5. This proposed construction applies to claims 3 and 7. 14 15 16 5 Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 6 of 16 Order of Method Steps No construction necessary. If the Court is inclined to address this issue, then it should hold that the steps of claim 3 may be performed in a consecutive manner, in a repeating manner, in an overlapping manner, or a combination of the three. If the Court is inclined to address this issue, then it should hold that the steps of claim 7 may be performed in a consecutive manner, in a repeating manner, in an overlapping manner, or a combination of the three, except that the ultimate step of claim 7 must follow or at least partially follow the penultimate step of claim 7. The elements of claim 3 and 7 must be executed in order. Moreover, "when the linked list is accessed" in the removing step refers to the accessing step, and the identifying and removing steps must occur during the same traversal of the linked list of records. The Court provisionally finds the term "when the linked list is accessed" to mean "both identification and removal of the automatically expired record(s) occurs during the same access of the linked list." The Court finds that the identification and removal steps occur during the same access. The "access" referred to in "removing at least some of the automatically expired records from the linked list when the linked list is accessed"17 is the same "access" of "accessing the linked list of records." In addition, the "identifying" step must start before "removal" can begin. However, identification need not be completed before removal can begin. The identification step may overlap with the 17 Claims 3 and 7, emphasis added. 6 Case 6:09-cv-00269-LED -JDL Document 326 Filed 10/29/10 Page 7 of 16 removal step. Furthermore, the ultimate step of claim 7 must follow or at least partially follow the penultimate step of claim 7. VIII.
