We reverse. 2 Appeal2014-009583 Application 11/063,284 STATEMENT OF THE CASE Appellants' invention relates to "communication of data over a plurality of parallel data communication paths." Spec. 1: 15. Claim 1 is illustrative and reproduced below: 1. A method for communicating data over parallel data paths comprising: characterizing each of a plurality of parallel data paths by repeatedly determining path properties, the plurality of parallel data paths defining a single virtual connection between a sending node and receiving node, wherein at least one of the plurality of parallel data paths comprises a plurality of intermediate nodes; and scheduling the transmission of data across the plurality of parallel data paths to meet an objective function, the scheduling based on the path properties. ANALYSIS THE OBVIOUSNESS REJECTION OF CLAIMS 1-3, 10, 14, 17, 37, 38, 45, 48, AND 52 BY PARTRIDGE AND O'NEILL The Examiner finds Partridge and 0 'Neill teach all limitations of claim 1. Ans. 2-7. The Examiner relies on Partridge for all claim limitations, except for the recited (claim 1) "wherein at least one of the plurality of parallel data paths comprises a plurality of intermediate nodes," for which the Examiner relies on 0 'Neill. Ans. 4--5. The Examiner reasons it would have been obvious to combine the teachings of the references. Ans. 5-7. Appellants present, among other arguments, the following principal argument: Even combined with a path as presently defined, Partridge cannot be applied to achieve the present claims. Partridge would 3 Appeal2014-009583 Application 11/063,284 still make decisions based on the status of the first link on the paths, which would not result in optimal decisions. Partridge cannot be extended to use paths without significant modifications, beyond the level of one of ordinary skill in the art. App. Br. 14. Appellants persuade us that the Examiner erred in the legal conclusion of obviousness. Although Partridge teaches scheduling over sublinks (see Ans. 3), the Examiner has not adequately explained how, Partridge would schedule based on repeatedly determined path properties over a path with intermediate nodes. The Examiner has not adequately explained how scheduling based on the first sublink in Partridge is scheduling based on path properties. To the extent Partridge would have been further modified, the Examiner has not adequately explained how or why such a modification would be made. Thus, on this record, modifying Partridge to use O'Neill's paths having intermediate nodes, in such a way to achieve the claimed invention as recited in claim 1, has not been shown to be obvious. In the Examiner's Answer, in response to Appellants' arguments, the Examiner explains "[t]here is teaching, suggestion, and motivation, in the above statement, to extend the design, of the Partridge reference, to encompass the Internet; thereby, adding intermediate nodes." Ans. 40 (citing Partridge i-f 4); see also Ans. 41 ("O'Neill, simply, provides further detail on how this design extension is performed: e.g. [0089] intermediate nodes."). We do not agree. Partridge (i-f 4) discloses Internet services and O'Neill (i-f 98) discloses intermediate nodes, but these disclosures are insufficient to explain how Partridge's operation (striping over available sub links) would be applied to a path with intermediate nodes. Again, the 4 Appeal2014-009583 Application 11/063,284 Examiner has not adequately explained how Partridge would schedule based on repeatedly determined path properties over a path with intermediate nodes, which requires more than simply transmission over available first sub links. Further, the various rationales set forth by the Examiner (see Ans. 41- 46) similarly fail to explain how Partridge's operation (striping over available sub links) would be applied to a path with intermediate nodes. Put another way, all of these rationales suggest that Partridge's sublinks are simply replaced with paths having intermediate nodes, but Partridge stripes packets over available sublinks and how this technique would have any applicability to higher-layer paths has not been established on the current record. We, therefore, are constrained by the record to not sustain the Examiner's rejection of claim 1. For these same reasons, we also do not sustain the Examiner's rejection of independent claim 3 7, which recites "repeatedly determining path properties," "at least one of the plurality of parallel data paths comprises a plurality of intermediate nodes," and "scheduling based on the path properties." For these same reasons, we also do not sustain the Examiner's rejection of independent claim 52, which recites "repeatedly determining path properties," "at least one of the plurality of parallel data paths comprises a plurality of intermediate nodes," and "scheduling based on the path properties." Further, we do not sustain the Examiner's rejection of dependent claims 2, 3, 10, 14, 17, 38, 45, and 48. 5 Appeal2014-009583 Application 11/063,284 THE REMAINING REJECTIONS All of the claims rejected in the remaining rejections depend variously from independent claims 1, 37, and 52. In making the remaining rejections, the Examiner does not overcome the deficiencies discussed above when addressing claim 1. See Ans. 21-39. We, therefore, do not sustain the rejection of claims 4---6 and 39--41 as obvious over Partridge, O'Neill, and Wallentin; the rejection of claims 7-9, 18, 42--44, and 49 as obvious over Partridge, O'Neill, and Butt; the rejection of claims 11, 13, 15, 16, and 46 as obvious over Partridge, O'Neill, and Bahadiroglu; the rejection of claims 12 and 47 as obvious over Partridge, O'Neill, and Su; the rejection of claims 19 and 50 as obvious over Partridge, O'Neill, and Haverinen; the rejection of claims 20 and 51 as obvious over Partridge, O'Neill, and Tomoe; and the rejection of claims 54 and 56 as obvious over Partridge, O'Neill, and Renwick. ORDER The Examiner's decision rejecting claims 1-20, 37-52, 54, and 56 is reversed. REVERSED 6 Copy with citationCopy as parenthetical citation
