“7. Conclusion Patent Owner has shown: (1) the amendment proposes a reasonable number of substitute claims; (2) the proposed substitute claims are supported in the original disclosure; (3) the amendment responds to a ground of unpatentability involved in the trial; and (4) the amendment does not seek to enlarge the scope of the claims of the patent or introduce new subject matter. Petitioner has not shown by a preponderance of the evidence that proposed substitute claims 44–47, 49, and 50 are unpatentable. Accordingly, Patent Owner’s Motion to Amend is granted.” slip op. at 82

“We recognize, however, “the testimony of one of ordinary skill in the art cannot supplant the total absence of structure from the specification.” Default Proof Credit Card Sys., Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1302 (Fed. Cir. 2005); see also Biomedino, LLC v. Waters Techs. Corp., 490 F.3d 946, 950–53 (Fed. Cir. 2007). “The prohibition against using expert testimony in this manner is a direct consequence of the requirement that the specification itself adequately disclose the corresponding structure.” Noah Sys., Inc. v. Intuit Inc., 675 F.3d 1302, 1312 (Fed. Cir. 2012) (citing AllVoice Computing PLC v. Nuance Commc'ns., required that the structure disclosed in the specification be more than simply a general purpose computer or microprocessor.” Aristocrat Techs. Austl. Pty Ltd. v. Int'l Game Tech., 521 F.3d 1328, 1333 (Fed. Cir. 2008). The specification must “disclose an algorithm for performing the claimed function.” Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1367 (Fed. Cir. 2008); Aristocrat, 521 F.3d at 1333. The Federal Circuit has held that “[t]he specification can express the algorithm ‘in any understandable terms including as a mathematical formula, in prose, or as a flow chart, or in any other manner that provides sufficient structure.’” Noah, 675 F.3d at 1312 (citing Finisar Corp. v. DirecTV Grp., Inc., 523 F.3d 1323, 1340 (Fed.Cir.2008) (internal citation omitted)). “Simply disclosing software, however, ‘without providing some detail about the means to accomplish the function[,] is not enough.’” Id. (citing Finisar, 523 F.3d at 1340–41 (citation omitted)). In the present proceeding, even assuming, arguendo, that the record sufficiently supports a finding that a POSITA would have known of FEC, CRC, ARQ, and hybrid ARQ protocols, Petitioner has not shown that the specification of the ’561 patent discloses a sufficient algorithm, whether “as a mathematical formula, in prose, or as a flow chart, or any other manner that provides sufficient structure” for the “means for detecting,” including an algorithm for performing any one or more of these protocols. Noah, 675 F.3d at 1312. The ’561 patent discloses “means (224) for detecting a need for retransmission of the received coded data block,” “CCU [Channel Coding Unit] [that] is responsible for channel coding, including forward error coding FEC” as well as detecting the “[t]he need for retransmission . . . by an error errors occurring on the channel with sufficient certainty.” Ex. 1001, code (57), 2:25, 6:64–65, 7:54–59; see id. at Fig. 5, Step 508, 10:41–44. Petitioner has not shown that the ’561 patent presents an algorithm for how the error detection code detects an error, nor explained the circumstances under which the error correcting code cannot correct errors and what constitutes “sufficient certainty.” Id. at 7:54–59. Although the ’561 patent discloses examples of incremental redundancy protocols such as “hybrid FEC/ARQ (Forward Error Correction/Automatic Repeat Request), which uses error correction coding in order to decrease the number of retransmissions,” it does not present an algorithm for implementing the same. Id. at 2:33–37. For the foregoing reasons and based on the entirety of the record developed during trial, we conclude that Petitioner fails to identify sufficient algorithmic structure corresponding to the “means for detecting” recited in independent claims 5 and 10.” slip op. at 15

In re Piasecki, 745 F.2d 1468, 1471–72 (Fed. Cir. 1984). However, to accord substantial weight to objective evidence requires the finding of a nexus between the evidence and the merits of the claimed invention. In re GPAC Inc., 57 F.3d 1573, 1580 (Fed. Cir. 1995); see also In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996) (“success is relevant in the obviousness context only if there is proof that the sales were a direct result of the unique characteristics of the claimed invention.”). Enfish contends that the claimed invention received industry accolades, including praise from Microsoft, satisfied a long-felt need, resulted in success where others had failed, as well as commercial success. PO Resp. 42–47. Enfish points to features of claim 17, which Enfish contends are the features of the claimed invention that resulted in the objective indicia of success to which Enfish refers. Id. at 43–44. Claim 17 of the ’775 patent, however, is challenged on the basis that it is anticipated by Visual Basic. Secondary considerations do not weigh into determinations regarding anticipation. Cohesive Techs., Inc. v. Waters Corp., 543 F.3d 1351, 1364 (Fed. Cir. 2008). Because we conclude that Microsoft has not shown that claims 51–53 of the ’775 patent are unpatentable for other reasons, the only claims that we need to evaluate are dependent claims 49 and 50 of the ’775 patent. Microsoft asserts that claims 49 and 50 are obvious over the combination of Visual Basic with a reference that teaches referencing objects through two-way pointers. Pet. 49 (citing Ex. 1106, 7:29–35). Enfish has not shown a nexus between any of the accolades or successes it says occurred and the use of two-way pointers.” slip op. at 24

“determine whether “cluster links” means relationships between two nodes, which are represented in data stored in a computer. Claim 1 recites a method of analyzing data in a database with indirect relationships using links and nodes. Claim 14 similarly recites a method for representing the relationship between nodes, using stored direct links, paths, and candidate cluster links. As explained in the ’494 Patent specification, data in the database may be represented as a node. Ex. 1001, 12:29–33. Exemplary nodes include an object or a portion of an object, a document or section of a document, and a World Wide Web page. Id. at 12:35–38. The ’494 Patent specification states that a link is a “relationship between two nodes.” Id. at 12:65–66. The ’494 Patent specification continues, “[a] link [] can be represented by a vector or an entry on a table and contain information for example, a from-node identification [] (ID), a to-node ID [], a link type [], and a weight.” Id. at 13:3–6. As described in the ’494 Patent specification, a link is represented in data stored in a computer. We, therefore, determine that “cluster links” means relationships, which are represented in data stored in a computer and are used for grouping interrelated nodes.” slip op. at 11

“As described in Fox SMART, the concentration tests that are cited by Petitioner are performed as part of forming the cluster tree. Id. Petitioner does not identify disclosure in Fox SMART of deleting clusters other than those that simply overlap, or duplicate, other clusters. Overlapping clusters are deleted following a routine that identifies plausible clustering with “no limit on overlap.” Id. Additionally, Fox SMART includes code that collects orphans. Id. at 52. Petitioner, however, has not shown that Fox SMART describes a subset which does not include these orphans. Dr. Fox’s supplemental testimony that “Fox SMART teaches that potential (i.e., candidate) clusters are rejected (‘deleted’) if they fail any one of these tests” (Ex. 1028 ¶ 281 (citing Ex. 1005, 51)) suggests that the terms “rejected” and “deleted” are the same. We do not agree. In view of Dr. Fox’s testimony in both of his Declarations and the testimony of Dr. Jacobs, we find that one of ordinary skill in the art reasonably would have understood Fox SMART as describing deleting overlap that had been generated by the immediately preceding software routine. Additionally, we find that one of ordinary skill in the art reasonably would have understood Fox SMART as describing that the tests referred to by Dr. Fox are processed during formation of the tree. We, therefore, determine that Dr. Fox’s testimony does not address persuasively the requirement in claim 1 of deriving a subset of the already generated candidate cluster links.” slip op. at 15

“arguments for the first time. Paper 44, 1. A reply may respond to arguments raised in the corresponding patent owner response. 37 C.F.R. § 42.23(a). Examples of indications that a new issue has been raised in a reply include new evidence necessary to make out a prima facie case for the unpatentability of a claim. Office Patent Trial Practice Guide, 77 Fed.Reg. 48,756, 48,767 (Aug. 14, 2012). We determine that the evidence presented in the Reply Fox Declaration that is discussed in this Decision properly responds to arguments raised in the Patent Owner Response. Additionally, we do not rely on evidence in the Reply Fox Declaration in our determination that Petitioner established by a preponderance of the evidence that claim 14 is unpatentable. For the reasons given, we deny Patent Owner’s Motion to Exclude.” slip op. at 22
