Patent Owner ____ Appeal 2013-007689 Inter partes Reexamination Control No. 95/001,533 United States Patent 7,417,568 B2 Technology Center 3900 ____________ Before ALLEN R. MacDONALD, THU A. DANG, and STEPHEN C. SIU, Administrative Patent Judges. SIU, Administrative Patent Judge. DECISION ON APPEAL Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 2 This proceeding arose from a third party request on behalf of CME Group, Inc., New York Mercantile Exchange, Inc., and Board of Trade of the City of Chicago, Inc. for an inter partes reexamination of U. S. Patent 7,417,568 B2 (the ’568 patent), entitled “System and Method for Data Feed Acceleration and Encryption,” assigned to Realtime Data LLC and issued to James J. Fallon, Paul F. Pickel, Stephen J. McErlain, and Carlton W. Melone (August 26, 2008). The Examiner refuses to adopt the proposed rejections of claims 3, 6-8, 10, 12, 14, 15, 17, 18, 20-27, 29-37, 40, 41, 45-51, 53-62, 67, 69, and 70. We have jurisdiction under 35 U.S.C. §§ 134(b) and 306. STATEMENT OF THE CASE The ’568 patent describes transmission of broadcast data over a communication channel using data compression and decompression (col. 6, ll. 4-7). Claim 20 on appeal reads as follows: 20. A method for creating a data feed dependent data compression routine, the method comprising: creating a description file that describes one or more data fields and one or more encoders associated with each data field; processing the description file with a data compression compiler; and outputting an executable file that is used to process a stream of data by recognizing data field types in the data stream and applying encoders associated with the recognized data field types to encode the data stream. (App. Br. 30, Claims Appendix.) The Examiner relies upon the following prior art references: Sebastian U.S. 6,253,264 B1 Jun. 26, 2001 Fascenda U.S. 5,045,848 Sept. 3, 1991 Carr U.S. 5,293,379 Mar. 8, 1994 Hauck U.S. 4,626,829 Dec. 2, 1986 Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 3 Willis U.S. 4,745,559 May 17, 1988 Birdwell U.S. 6,032,197 Feb. 29, 2000 Osler U.S. 6,768,749 B1 Jul. 27, 2004 Franaszek U.S. 5,870,036 Feb. 9, 1999 XML-Xpress White Paper, December 2000 (“XML”).

The Requester appeals the Examiner’s decision not to adopt the following proposed rejections: Claims 6, 10, 12, 14, 15, 17, 18, 20-26, 29-32, 40, and 46-48 under 35 U.S.C. § 102(b) as being anticipated by XMill; Claims 3, 6-8, 33-37, 51, 53-56, and 60-62 under 35 U.S.C. § 103(a) as unpatentable over XMill, Danskin-1, and Birdwell; Claims 26, 27, and 49 under 35 U.S.C. § 103(a) as unpatentable over XMill and Willis; Claims 6-8, 12, 14, 15, 17, 18, 20-26, 29-32, 34-37, 40, and 46-48 under 35 U.S.C. § 102(b) as being anticipated by Danskin-1; Claim 50 under 35 U.S.C. § 103(a) as unpatentable over Danskin-1, alone or in combination with Danskin-2; Claims 3, 33, 37, 53-62, 69, and 70 under 35 U.S.C. § 103(a) as unpatentable over Danskin-1 and Birdwell; Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 4 Claims 26, 27, and 49 under 35 U.S.C. § 103(a) as unpatentable over Danskin-1 and Willis; Claims 6, 10, 12, 15, 20-25, 29-33, and 40 under 35 U.S.C. § 102 as being anticipated by Sebastian; Claims 14, 26, 27, 37, and 49 under 35 U.S.C. § 103(a) as unpatentable over Sebastian and Willis; Claims 30, 32, 33, 47, and 48 under 35 U.S.C. § 103(a) as unpatentable over Sebastian and Osler; Claim 46 under 35 U.S.C. § 103(a) as unpatentable over Sebastian, Willis, and Osler; Claims 14 and 15 under 35 U.S.C. § 103(a) as unpatentable over Sebastian and Danskin-1; Claim 3 under 35 U.S.C. § 103(a) as unpatentable over Sebastian and Birdwell; Claims 3, 6, 8, 14, 15, 31, 32, 40, and 47 under 35 U.S.C. § 103(a) as unpatentable over Carr and Franaszek; Claims 15, 26, 27, and 49 under 35 U.S.C. § 103(a) as unpatentable over Carr, Franaszek, and Fascenda; Claims 25, 27, 29, 30, 33, 37, 47 and 48 under 35 U.S.C. § 103(a) as unpatentable over Carr, Franaszek, and Birdwell; Claims 6, 8, 12, 31, 32, 34, 40, 41, and 45 under 35 U.S.C. § 102 as being anticipated by Hauck; Claims 3, 27, 29, 30, 33, 37, and 67 under 35 U.S.C. § 103(a) as unpatentable over Hauck and Birdwell; Claims 6, 14, 20, 22, 24, 25, 31, 32, 40, 47, and 48 under 35 U.S.C. § 102 as being anticipated by XML; Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 5 Claims 3, 15, and 23 under 35 U.S.C. § 103(a) as unpatentable over XML and Carr; Claims 25, 27, 29, 30, 33, and 37 under 35 U.S.C. § 103(a) as unpatentable over XML and Birdwell; Claims 14, 26, 27, 37, and 46 under 35 U.S.C. § 103(a) as unpatentable over XML and Willis; Claims 15, 26, 27, 46, and 49 under 35 U.S.C. § 103(a) as unpatentable over XML and Fascenda; Claims 6, 29, 30, 47, and 48 under 35 U.S.C. § 103(a) as unpatentable over XML and Sebastian; Claim 14 under 35 U.S.C. § 103(a) as unpatentable over Carr and Franaszek. The Requester also argues that claims 1-41, 45-62, 67, 69, and 70 are not entitled to the priority date of U.S. Patent Application No. 09/969,987, filed October 3, 2001. DISCUSSION XMill Reference The Examiner finds that XMill fails to disclose a data packet because, according to the Examiner, a “packet” as recited in claim 3, for example, “include[s] more than a mere segregation of data” (ACP 21). In support of this finding, the Examiner states that Birdwell discloses “‘packets’ with uncompressed/compressed headers,” Carr discloses “data ‘packets’ which include at least static and dynamic fields,” and XML discloses “compression at a ‘file’ level [that is distinguished] from compression at the ‘packet’ level” (ACP 21). Hence, the Examiner defines a data packet, as recited in Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 6 claim 3, for example, as a “segregation of data” that also must include “uncompressed/compressed headers” (according to Birdwell), “static and dynamic fields” (according to Carr), and a method of compression that is “distinguished from” compression of a “file” (according to XML). The Examiner relies on the Birdwell reference to support the position that a data packet must contain “uncompressed/compressed headers.” As the Examiner points out, Birdwell discloses “full-length data packets, which have uncompressed headers, and reduced-length data packets, which have compressed headers” (col. 2, ll. 15-17). However, at best, Birdwell discloses the use of full-length data packets, which have compressed headers and reduced-length data packets, which have compressed headers. The Examiner does not persuasively demonstrate that Birdwell also discloses that all data packets must include compressed or uncompressed headers and that one of ordinary skill in the art would understand that any segregation of data lacking an uncompressed or compressed header is not a data packet. Similarly, the Examiner relies on the Carr reference to support the position that a data packet must contain “static and dynamic fields.” As the Examiner points out, Carr discloses a system “that employs data packets which include at least static and dynamic fields” (col. 3, ll. 31-33). At best, Carr discloses a system that utilizes data packets with static or dynamic fields. The Examiner does not persuasively demonstrate that Carr also discloses that all data packets must include static and/or dynamic fields and that one of ordinary skill in the art would understand that any segregation of data lacking a static or dynamic field is not a data packet. The Examiner relies on the XML reference to support the position that a data packet must be compressed in a manner that is “distinguished from” Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 7 compression of a “file.” As the Examiner points out, XML discloses a “demo” that “compresses at the file level” and a system in which “each input packet is encoded as [quickly] as it is received” (p. 4). At best, XML discloses a system that encodes packets as quickly as they are received. The Examiner does not persuasively demonstrate that XML discloses that all data packets must include any specific feature. While XML discloses, a system that encodes packets as quickly as the packets are received, we disagree with the Examiner that the system quickly encoding packets constitutes a definition of a data packet as would have been understood by one of ordinary skill in the art. Given that none of Birdwell, Carr, or XML discloses a specific definition of a data packet and none of the references disclose any specifically required feature of a data packet as would have been understood by one of ordinary skill in the art, we cannot agree with Examiner’s position a data packet must “include . . . more than a mere segregation of data” (ACP 21). Patent Owner argues that a “data packet” is a “unit of information transmitted from one device to another on a network” (PO Rebuttal Br. 6, citing Microsoft Computer Dictionary, 327 (4th ed. 1999)). Even assuming Patent Owner’s contention to be correct, Patent Owner has not persuasively demonstrated that XMill fails to disclose a “unit of information transmitted from one device to another.” For example, XMill discloses “data exchange” (p. 1) and an “information source, a channel, and a destination” for data and “information can be sent by the source to the destination through the channel” (p. 8). Hence, XMill discloses data that is transmitted (i.e., from a Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 8 source to a destination), which Patent Owner argues is the definition of the term “packet.” Also, as the Requester points out, the Specification discloses that “[i]f there is internal structure to packets, such as a header . . ., additional global states could be added” (col. 10, ll. 39-53; 3PR App. Br. 7; Declaration under 37 C.F.R. 1.132 of Paul C. Clark, dated August 17, 2011 (“Clark Declaration”), ¶ 47). In other words, the Specification does not disclose that a data packet must contain an internal structure. Indeed, the Specification explicitly discloses that a packet may have an internal structure (i.e., “if” there is an internal structure), such as a header, and therefore implies that an internal structure is an optional feature of a data packet. The Examiner does not persuasively rebut the Requester’s argument. Therefore, we agree with Requester that a broad but reasonable construction of the term “data packet” includes a segregation of data that does not require a specific internal structure. XMill discloses compression and decompression of XML data (p. 2, l. 1) that is “semistructured data” (p. 2, l. 4) that may be grouped into “containers” (p. 2. – “grouping data items in containers”). The Examiner does not adequately point out any substantial differences between the “semistructured data” in containers (i.e., segregation of data) and the “data packet” as claimed. While Patent Owner argues that “the container-specific encoders in XMill [do not] apply to, or operate on ‘data packets’” (PO Rebuttal Br. 10), Patent Owner does not persuasively demonstrate a difference between the “container” of XMill and the claimed “packet.” Both the “container” of XMill and the claimed “packet” contain data and are transmitted from a source to a destination. Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 9 The Examiner states that XMill fails to disclose recognizing a data field type of a data field included in a packet because, according to the Examiner, XMill fails to disclose a data packet (ACP 23, 25). We disagree with the Examiner for previously stated reasons and for reasons set forth by the Requester (3PR App. Br. 6-8). The Examiner also states that while XMill discloses a compressor, the compressor of XMill is not the same as an “executable file” as claimed because the compressor of XMill, according to Requester, is the claimed “encoder” and “cannot read on both the distinctly claimed ‘executable file’ and ‘encoder’” (ACP 28). Claims 20-23, for example, recite an executable file that is used to process a stream of data by recognizing data field types in the data stream and applying encoders associated with the recognized data field types. We disagree with the Examiner for at least the reasons set forth by the Requester (3PR App. Br. 8-9). As the Requester points out, XMill discloses different compressors that are used to compress different types of data, including “specialized compressors if [users] have complex, application specific data types” (p. 2).1 Hence, XMill discloses processing a stream of data and applying a corresponding encoder based on the types of data in the data stream. The Examiner does not persuasively demonstrate a difference between applying encoders associated with recognized data types (e.g., applying a specialized 1 XMill also discloses, for example, “[c]omplex compressors . . . for a variety of specialized data types, e.g. images, sound, DNA sequences” (p. 8) and that “users can write new . . . compressors and link them to XMill” which is “useful when . . . data contains highly specialized types, like DNA sequences, for which special purpose compressors exists” (p. 9, 4th paragraph). Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 10 compressor to compress data of a corresponding specific data type as disclosed by XMill) and the claim limitation of applying encoders associated with the recognized data field types. The Examiner states that the compressor of XMill “cannot read on both the distinctly claimed ‘executable file’ and ‘encoder’” (ACP 28). However, as the Requester points out, XMill discloses, for example, a “path processor that determines how to map data values to containers” (p. 9, 2nd paragraph) and associating “semantic compressors with containers” (p. 9, 4th paragraph), the data in the containers being compressed by the corresponding compressor (p. 9, 3rd paragraph – “all containers are . . . stored on disk, and the compression resumes . . . “input file[s] . . . are compressed independently”). In other words, XMill discloses an “executable file” (e.g., a path processor that determines how to map data values to containers – p. 9, Fig. 4) the recognizes data types of the input data (and sorted into containers) and applies a corresponding encoder (data in containers are compressed by corresponding specialized encoders). The Examiner does not persuasively demonstrate a difference between XMill and the disputed claim limitations. The Examiner states that XMill (and Danskin-1) fails to disclose a financial data feed (ACP 31, citing Clark Declaration, and Modestino Declaration). Claims 53-62, for example, recite recognizing a data field type of a data field in a financial data feed. We disagree with the Examiner for at least the reasons set forth by the Requester (3PR App. Br. 9-11). In addition, our reviewing court has held that nonfunctional descriptive material cannot lend patentability to an invention that otherwise would have been unpatentable over the prior art. In re Ngai, 367 F.3d 1336, Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 11 1339 (Fed. Cir. 2004). Cf. In re Gulack, 703 F.2d 1381, 1385 (Fed. Cir. 1983) (when descriptive material is not functionally related to the substrate, the descriptive material will not distinguish the invention from the prior art in terms of patentability). The Examiner need not give patentable weight to descriptive material absent a new and unobvious functional relationship between the descriptive material and the substrate. See In re Lowry, 32 F.3d 1579, 1582-83 (Fed. Cir. 1994). In the present case, claims 53-62 recite a data field in a financial data feed. In each of these claims, descriptive material is recited without a specific functional relationship to the “substrate”. For example, while claim 53 recites the data field is in a “financial data feed,” claim 53 does not recite a specific functional relationship between the type of data (i.e., “financial data feed”) and any of the steps of the method of recognizing a data field, selecting an encoder, compressing data, broadcasting the compressed data, or utilizing a descriptor. Instead, each of the steps of the method of claim 53 would exhibit no functional difference if the type of data (i.e., “financial data feed”) were to include other types of data (e.g., non-financial data) since claim 53 does not require any specific function of the specific type of data. Hence, we need not accord patentable weight to non-functional descriptive material (i.e., “financial data feed”). As such, the Examiner has not demonstrated that XMill fails to disclose features recited in claims 53- 62. The Examiner does not provide additional findings with respect to any of Danskin, Birdwell, or Willis in combination with XMill. Reversal of the Examiner’s refusal to adopt the proposed rejections of claims 3, 6-7, 10, 12, 14, 15, 17, 18, 20-27, 29-37, 40, 46-49, 51, 53-56, 60- Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 12 62, 67, 69, and 70 over XMill, either alone or in combination with Danskin- 1, Birdwell, and/or Willis renders it unnecessary to reach the propriety of the Examiner’s refusal to adopt proposed rejections of those claims on a different basis. Cf. In re Gleave, 560 F.3d 1331, 1338 (Fed. Cir. 2009). As such, we need not reach the propriety of the Examiner’s refusal to adopt the proposed rejections of those claims over Danskin-1, Danskin-2, Birdwell, Willis, Sebastian, Willis, Osler, Carr, Franaszek, Fascenda, Hauck, or XML. We also need not consider the Requester’s arguments pertaining to priority of the ’568 patent. Danskin-1 – Claims 50 and 57-59 The Examiner also finds that Danskin-1 discloses a “type of the message” but that the type of the message “do[es] not relate to encoders” (ACP 24). Hence, the Examiner finds that Danskin-1 fails to disclose, “providing a descriptor with the encoded data which identifies the selected encoder.” Claim 50, which depends from claim 1, recites providing a descriptor with the encoded data which identifies the selected encoder. Claim 53 recites recognizing a data field type and selecting an encoder associated with the recognized data field type. Requester argues that Danskin discloses “message-type tags and opcodes . . . which identifies the selected encoder” (3PR App. Br. 13, citing Danskin 83, 91, 120). We agree with Requester that Danskin discloses “tags” that describe a “message type” (p. 121) and “opcodes” (p. 120; Fig. 16-28). However, Requester does not sufficiently demonstrate that either the “message-type tags” or the “opcodes” “correspond to the encoders for that message type” as Requester asserts. Rather, it appears that the “tag” Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 13 (along with “Offset”) corresponds to a “Predictive Model” (p. 121; Fig. 16- 28) that, in turn, “indicates which contexts were used to index models for prediction” (p. 121, ll. 1-2). Thus, the “tag” of Danskin corresponds to a predictive model indicating a context to index models for prediction rather than an encoder used to compress data blocks as recited in claim 1. Requester has also provided insufficient support for the contention that the “opcodes” of Danskin indicate encoders used to compress data blocks. Rather, the “opcode” of Danskin appears to be a field in a request that corresponds to a “predictive model” described by a “tag” and offset (Figs. 16-28). Alternatively, one of ordinary skill in the art would have utilized a plain and customary meaning of the term “opcode” to include an “operational code” that is used to specify an operation to be performed. In either case, whether the “opcode” of Danskin corresponds to a “predictive model” or whether the “opcode” of Danskin indicates an operation to be performed, Requester has not adequately demonstrated that the “opcode” indicates an encoder used to compress data. Requester does not rely on Danskin-2 or Birdwell to make up for the deficits of Danskin-1. The Examiner did not err in not adopting the proposed rejection of claims 50 and 57-59 over Danskin-1 alone or in combination with Danskin-2 or Birdwell. Hauck – claims 41 and 45 As described above, the Examiner finds that Hauck fails to disclose a data “packet” (ACP 23). Claims 41 and 45, which depend from claim 1, recite a data packet. We disagree with the Examiner for at least the reasons Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 14 set forth by the Requester (3PR App. Br. 23-24) and reasons previously described above. For example, Hauck discloses “compressing and/or decompressing data during transmission of data within a computer system” (col. 5, ll. 45- 47). The Examiner does not persuasively demonstrate a difference between computer data that is transmitted (i.e., transmission of data within a computer system) and a data packet (or a “segregation” of data – see above). The Examiner erred in not adopting the proposed rejection of claims 41 and 45 over Hauck. DECISION The Examiner’s decision not to reject claim 50 under 35 U.S.C. § 103(a) as unpatentable over Danskin-1, alone or in combination with Danskin-2, and claims 57-69 under 35 U.S.C. § 103(a) as unpatentable over Danskin-1 and Birdwell is affirmed. The Examiner’s decision not to reject claims 6, 10, 12, 14, 15, 17, 18, 20-26, 29-32, 40, and 46-48 under 35 U.S.C. § 102(b) as being anticipated by XMill; claims 3, 6-8, 33-37, 51, 53-56, and 60-62 under 35 U.S.C. § 103(a) as unpatentable over XMill, Danskin-1, and Birdwell; claims 26, 27, and 49 under 35 U.S.C. § 103(a) as unpatentable over XMill and Willis; and claims 41 and 45 under 35 U.S.C. § 102 as being anticipated by Hauck is reversed. Pursuant to 37 C.F.R. § 41.77(a), the above-noted reversal constitutes a new ground of rejection. Section 41.77(b) provides that “[a] new ground of rejection . . . shall not be considered final for judicial review.” That section also provides that Patent Owner, WITHIN ONE MONTH FROM Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 15 THE DATE OF THE DECISION, must exercise one of the following two options with respect to the new grounds of rejection to avoid termination of the appeal proceeding as to the rejected claims: (1) Reopen prosecution. The owner may file a response requesting reopening of prosecution before the examiner. Such a response must be either an amendment of the claims so rejected or new evidence relating to the claims so rejected, or both. (2) Request rehearing. The owner may request that the proceeding be reheard under § 41.79 by the Board upon the same record. The request for rehearing must address any new ground of rejection and state with particularity the points believed to have been misapprehended or overlooked in entering the new ground of rejection and also state all other grounds upon which rehearing is sought. In accordance with 37 C.F.R. § 41.79(a)(1), the “[p]arties to the appeal may file a request for rehearing of the decision within one month of the date of: . . . [t]he original decision of the Board under § 41.77(a).” A request for rehearing must be in compliance with 37 C.F.R. § 41.79(b). Comments in opposition to the request and additional requests for rehearing must be in accordance with 37 C.F.R. § 41.79(c) & (d), respectively. Under 37 C.F.R. § 41.79(e), the times for requesting rehearing under paragraph (a) of this section, for requesting further rehearing under paragraph (d) of this section, and for submitting comments under paragraph (c) of this section may not be extended. An appeal to the United States Court of Appeals for the Federal Circuit under 35 U.S.C. §§ 141-144 and 315 and 37 C.F.R. § 1.983 for an inter partes reexamination proceeding “commenced” on or after November Appeal 2013-007689 Reexamination Control 95/001,533 Patent 7,417,568 B2 16 2, 2002 may not be taken “until all parties' rights to request rehearing have been exhausted, at which time the decision of the Board is final and appealable by any party to the appeal to the Board.” 37 C.F.R. § 41.81.
