AND LG ELECTRONICS, INC.,1 Petitioner, v. UNILOC 2017 LLC, Patent Owner. ____________ IPR2019-00510 Patent 6,868,079 B1 ____________ Before SALLY C. MEDLEY, JEFFREY S. SMITH, and GARTH D. BAER, Administrative Patent Judges. MEDLEY, Administrative Patent Judge. JUDGMENT Final Written Decision Determining Challenged Claim Unpatentable 35 U.S.C. § 318(a) 1 Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. (collectively “Samsung”) were terminated from the proceeding. Paper 20. IPR2019-00510 Patent 6,868,079 B1 2 I. INTRODUCTION Apple Inc., LG Electronics, Inc., Samsung Electronics Co., Ltd., and Samsung Electronics America, Inc. (collectively “Petitioner”) filed a Petition for inter partes review of claims 17 and 18 of U.S. Patent No. 6,868,079 B1 (Ex. 1001, “the ’079 patent”). Paper 2 (“Pet.”). Uniloc 2017 LLC (“Patent Owner”) filed a Preliminary Response. Paper 6 (“Prelim. Resp.”). Upon consideration of the Petition and Preliminary Response, we instituted inter partes review, pursuant to 35 U.S.C. § 314, as to claims 17 and 18 based on all challenges set forth in the Petition. Paper 7 (“Decision to Institute” or “Dec.”). Subsequent to institution, Patent Owner filed a Patent Owner Response (Paper 9, “PO Resp.”), Petitioner filed a Reply to Patent Owner’s Response (Paper 10, “Pet. Reply”), and Patent Owner filed a Sur-reply (Paper 11, “Sur-reply”). On April 23, 2020, we held an oral hearing. A transcript of the hearing is of record. Paper 17 (“Tr.”). On May 15, 2020, Petitioner filed an unopposed request to withdraw the challenges set forth in the Petition with respect to claim 18. Ex. 3001. In essence, Petitioner requests removal of the challenges to claim 18 from the Petition as if claim 18 was never challenged. Id. We grant Petitioner’s request. We modify our Decision to Institute to institute inter partes review, pursuant to 35 U.S.C. § 314, as to only claim 17 based on all challenges set forth in the Petition. On June 8, 2020, we granted the parties’ joint motion to terminate the proceeding with respect to Samsung. Paper 20. In our Scheduling Order, we notified the parties that “any arguments not raised in the [Patent Owner] response may be deemed waived.” See Paper 8, 7; see also Office Patent Trial Practice Guide, 77 Fed. Reg. 48,756, IPR2019-00510 Patent 6,868,079 B1 3 48,766 (Aug. 14, 2012) (“The patent owner response . . . should identify all the involved claims that are believed to be patentable and state the basis for that belief.”). Patent Owner argues that it “does not concede, and specifically denies, that there is any legitimacy to any arguments in the instant Petition that are not specifically addressed” in its Patent Owner Response. PO Resp. 19 n.9. We decline to speculate as to what Patent Owner considers is not legitimate in the Petition. Any arguments for patentability not raised in the Patent Owner Response are deemed waived. For the reasons that follow, we conclude that Petitioner has proven by a preponderance of the evidence that claim 17 of the ’079 patent is unpatentable. A. Related Matters Petitioner and Patent Owner indicate that the ’079 patent is the subject of several court proceedings. Pet. 78–79; PO Resp. 3. The ’079 patent also is the subject of Board proceeding IPR2020-00038. IPR2020-00038 was filed by Motorola Mobility LLC and institution was granted. See Motorola Mobility LLC, v. Uniloc 2017 LLC, IPR2020-00038, Paper 9 (PTAB April 13, 2020). B. The ’079 Patent The ’079 patent describes “a method of operating a radio communication system,” where the radio communication system is “required to be able to exchange [signaling] messages between a Mobile Station (MS) and a Base Station (BS).” Ex. 1001, 1:7–8, 1:18–20. The ’079 patent further describes that an object of the invention “is to improve the efficiency of the method by which a MS requests resources from a BS.” Id. at 1:56–58. The ’079 patent describes a secondary station (i.e., MS) transmitting a IPR2019-00510 Patent 6,868,079 B1 4 request for resources to a primary station (i.e., BS) in a time slot allocated to the secondary station, where the secondary station re-transmits the request in at least a majority of its allocated time slots until an acknowledgment is received from the primary station. Id. at 1:60–67. Because there is no possibility of requests from different secondary stations colliding, a secondary station can re-transmit requests in each allocated time slot. Id. at 2:3–5. Further, the primary station can improve the accuracy with which it determines whether a request was sent by a particular secondary station if the received signal strength is close to the detection threshold by examining the received signals in multiple time slots allocated to the secondary station in question. Id. at 2:9–14. An example radio communication system is illustrated in Figure 1, reproduced below. IPR2019-00510 Patent 6,868,079 B1 5 Figure 1 is a block diagram of a radio communication system comprising a primary station (BS) 100 and a plurality of secondary stations (MS 110). Id. at 3:10–12. Communication from BS 100 to MS 110 takes place on downlink channel 122, while communication from MS 110 to BS 100 takes place on uplink channel 124. Id. at 3:19–21. C. Challenged Claim Petitioner challenges independent claim 17 of the ’079 patent. Claim 17 is reproduced below. 17. A method of operating a radio communication system, comprising: allocating respective time slots in an uplink channel to a plurality of respective secondary stations; and transmitting a respective request for services to establish required services from at least one of the plurality of respective secondary stations to a primary station in the respective time slots; wherein the at least one of the plurality of respective secondary stations re-transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgement is received from the primary station, wherein the primary station determines whether a request for services has been transmitted by the at least one of the plurality of respective secondary stations by determining whether a signal strength of the respective transmitted request of the at least one of the plurality of respective secondary stations exceeds a threshold value. Ex. 1001, 8:12–33. IPR2019-00510 Patent 6,868,079 B1 6 D. Asserted Grounds of Unpatentability As modified above, we instituted trial based on all asserted grounds of unpatentability under 35 U.S.C.2 as follows: Claim 35 U.S.C. § References 17 103(a) Wolfe3, Bousquet4, Patsiokas5 17 103(a) Wolfe, Bousquet, Everett 6, Patsiokas II. ANALYSIS A. Principles of Law To prevail in its challenge to Patent Owner’s claim, Petitioner must demonstrate by a preponderance of the evidence7 that the claim is unpatentable. 35 U.S.C. § 316(e) (2012); 37 C.F.R. § 42.1(d) (2018). A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject 2 The Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), amended 35 U.S.C. §§ 102 and 103. Because the ’079 patent has an effective filing date before the effective date of the applicable AIA amendments, we refer to the pre-AIA versions of 35 U.S.C. §§ 102 and 103. 3 US 4,763,325, issued August 9, 1988 (Ex. 1005, “Wolfe”). 4 US 6,298,052 B1, issued October 2, 2001 (Ex. 1006, “Bousquet”). 5 PCT Application Publication No. WO 1992/21214, published November 26, 1992 (Ex. 1007, “Patsiokas”). 6 VERY SMALL APERTURE TERMINALS (VSATS), Institution of Electrical Engineers (IEE), Telecommunication Series 28, First Edition (John L. Everett ed., Peter Peregrinus Ltd. 1st ed. 1992) (“Everett,” filed as Part 1 and Part 2, both parts identified as Ex. 1008). See also Ex. 1017 ¶¶ 5–7. 7 The burden of showing something by a preponderance of the evidence requires the trier of fact to believe that the existence of a fact is more probable than its nonexistence before the trier of fact may find in favor of the party who carries the burden. Concrete Pipe & Prods. of Cal., Inc. v. Constr. Laborers Pension Tr. for S. Cal., 508 U.S. 602, 622 (1993). IPR2019-00510 Patent 6,868,079 B1 7 matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness.8 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). B. Level of Ordinary Skill In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). Petitioner relies on the testimony of Dr. Paul Steffes, who testifies that a person with ordinary skill in the art would have had “a Master of Science Degree in an academic area emphasizing telecommunications systems, or an equivalent field (or a similar technical Master’s Degree, or higher degree) with a concentration in telecommunications systems” or “a Bachelor’s Degree (or higher degree) in an academic area emphasizing telecommunications systems with two or more years of work experience in telecommunications systems.” Pet. 7–8 (citing Ex. 1003 ¶ 31). Patent Owner does not propose an alternative assessment. See generally PO Resp. 8 Patent Owner does not present any objective evidence of nonobviousness as to the challenged claim. IPR2019-00510 Patent 6,868,079 B1 8 We adopt Dr. Steffes’s assessment of a person with ordinary skill in the art as it is consistent with the ’079 patent and the asserted prior art. We further note that the prior art of record in the instant proceeding reflects the appropriate level of ordinary skill in the art. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (holding the Board may omit specific findings as to the level of ordinary skill in the art “where the prior art itself reflects an appropriate level and a need for testimony is not shown”). C. Claim Construction In an inter partes review for a petition filed on or after November 13, 2018, “[claims] of a patent . . . shall be construed using the same claim construction standard that would be used to construe the [claims] in a civil action under 35 U.S.C. § 282(b), including construing the [claims] in accordance with the ordinary and customary meaning of such claims as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” See Changes to the Claim Construction Standard for Interpreting Claims in Trial Proceedings Before the Patent Trial and Appeal Board, 83 Fed. Reg. 51,340, 51,358 (Oct. 11, 2018) (amending 37 C.F.R. § 42.100(b) effective November 13, 2018) (now codified at 37 C.F.R. § 42.100(b) (2019)); see also Phillips v. AWH Corp., 415 F.3d 1303, 1312– 14 (Fed. Cir. 2005). “acknowledgment” Claim 17 recites “wherein the at least one of the plurality of respective secondary stations re-transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgment is received from the primary station.” Petitioner proposes that “acknowledgment” should be construed to mean “a message sent from IPR2019-00510 Patent 6,868,079 B1 9 the primary station to the secondary station stating the primary station’s receipt of the secondary station’s request.” Pet. 8–9 (citing Ex. 1003 ¶ 34). In our Decision to Institute, we adopted Petitioner’s proposed claim construction for “acknowledgment” to mean “a message sent from the primary station to the secondary station stating the primary station’s receipt of the secondary station’s request.” Dec. 6–7. Neither party has indicated that our interpretation was improper, and we do not perceive any reason or evidence that now compels any deviation from our initial interpretation. Accordingly, “acknowledgment” means “a message sent from the primary station to the secondary station stating the primary station’s receipt of the secondary station’s request.” For purposes of this Decision, we need not expressly construe any other claim term. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (holding that “only those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy”); see also Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs. in the context of an inter partes review). D. Asserted Obviousness of Claim 17 over Wolfe, Bousquet, Everett, and Patsiokas Petitioner contends claim 17 is unpatentable under 35 U.S.C. § 103(a) as obvious over Wolfe, Bousquet, Everett, and Patsiokas. Pet. 16–57, 73– 78. In support of its showing, Petitioner relies upon the declaration of Dr. Steffes. Id. (citing Ex. 1003). IPR2019-00510 Patent 6,868,079 B1 10 1. Wolfe Wolfe describes a method of frame management in a time division multiple access (TDMA) communication system in which a fixed time frame is divided into segments that are assigned to separate stations. Ex. 1005, 4:47–51. Each station is responsible for the management of its own segment. Id. at 4:51–52. The frame is further provided with an overflow area. Id. at 4:52–53. Whenever a station overflows the capacity of its own assigned segment, a request is made to a central station to assign a small slot in the overflow area to that station. Id. at 4:53–56. The control of the slot reverts to the central station when its use by the station terminates. Id. at 4:56–57. An example format of a frame of a TDMA system is illustrated in Figure 3 reproduced below. Figure 3 is a timing diagram illustrating a “format for a TDMA frame”. Id. at 5:16–17. “The frame begins with two reference bursts RBa and RBb, which are separately assigned to each of two reference stations.” Id. at 5:17–20. “A preallocated segment is subdivided into traffic bursts TB1 – TBN” where “[e]ach of the traffic bursts are assigned to one of N ground stations 10.” Id. at 5:35–36. The TDMA frame also includes an overflow area that is divided into overflow slots, where each of the overflow slots is assigned to one of traffic bursts TB’1 – TB’M, and where unused slots represent spare overflow capacity. Id. at 6:1–4. IPR2019-00510 Patent 6,868,079 B1 11 2. Bousquet Bousquet describes a shared resource transmission system that is used to set up transmission between a calling station and a called station. Ex. 1006, 1:7–9. The system entails a calling station sending data packets using a resource shared with other stations, where the data packets are access packets for setting up a call between a calling station and a called station. Id. at 1:18–21. “The various stations share the resource without any prior reservation of time slots and without any temporal synchronization of the stations.” Id. at 1:22–24. “Because there is no reservation, collisions can occur between access packets sent by different stations.” Id. at 1:24–26. To limit call set-up time and the probability of collision of access packets transmitted by a station, each station requiring to set up a call transmits at least two access packets without waiting for an acknowledgment between sending the access packets. Id. at 2:49–54. More specifically, the same access packet is sent n times (n>1) in a given time period whether an acknowledgment message is received from the station to which these packets are sent or not. Id. at 2:54–57. “The systematic repetition of the access packets in the predefined time period therefore increases the probability that at least one of the packets will reach the destination station, which reduces the time necessary to set up a call.” Id. at 3:53–56. 3. Patsiokas Patsiokas describes a method and apparatus whereby a communication unit transmits a communication channel request and the nearest base site makes the communication channel grant. Ex. 1007, 4:11– 14.9 “A base site receives the channel request signal, measures the received 9 Citations are to page numbers located at the bottom of the pages. IPR2019-00510 Patent 6,868,079 B1 12 signal strength (RSS or RSSI) level of the received signal, and if that level is above a first threshold level, a communication channel is granted to the requesting unit, thus establishing a communication link.” Id. at 4:14–18. The first threshold level is a predetermined value of decibels above a maximum sensitivity level of a base site. Id. at 6:34–36. Then, the base site maintains the communication link as long as the RSSI level does not drop below a second threshold level that is substantially lower than the first threshold level. Id. at 4:18–21. The second threshold level is the maximum sensitivity level of the base site. Id. at 6:30–31. 4. Everett Everett describes a communication system involving “Very Small Aperture Terminals (VSATs),” where a VSAT includes any form of small terminal system. Ex. 1008, 1.10 Typically, a VSAT communication system, or VSAT system, comprises a hub earth station, with a larger aperture antenna, controlling a cluster of VSATs, with smaller antennas. Id. at 2–3. The objective of the VSAT system is to provide an end-to-end communication link for a user. Id. at 8. An example VSAT system is illustrated in Figure 1.6 reproduced below. 10 Like the parties do, we cite to the internal page numbers of the pages rather than the page numbers included at the bottom of each page. IPR2019-00510 Patent 6,868,079 B1 13 Figure 1.6 illustrates three forms of a VSAT system. Id. at 11–12. According to Everett, these three forms include: (a) data distribution (involving a one-way communication link); (b) data gathering (also involving a one-way communication link); or (c) interactive (involving a two-way communication link). Id. at 11. A typical two-way VSAT system involves a hub in a star configuration transmitting a time division multiplex (TDM) stream to all VSATs in the network. Id. at 14. A VSAT with a message for the hub will transmit a short duration burst on a calling channel requesting access to a channel to transmit its message. Id. The hub acknowledges the request, assigns a channel and the VSAT changes frequency and transmits its message. Id. In a busy network, there will be collisions between some access request bursts and the VSAT may not get an acknowledgment from the hub. Id. Under these circumstances, the VSAT re-transmits its burst request after a pseudo randomly determined interval IPR2019-00510 Patent 6,868,079 B1 14 and continues doing so until it receives an acknowledgment and is assigned a channel. Id. Everett further describes an access channel that provides all the signaling information from a VSAT to a hub, where the VSAT can, inter alia, request a channel, and where the VSAT can re-transmit this request after a pre-determined delay in the event of a collision with another channel request sent by another VSAT. Id. at 337–38. Everett further describes a control channel, where the control channel is a signaling channel used by the hub to respond to VSAT requests on the access channel. Id. at 338. The control channel has a defined packet structure to allow responses to the VSAT, including, inter alia, an acknowledge channel used to send back “clear-to-transmit” messages to the VSAT. Id. at 339. 5. Discussion Petitioner contends that the “Wolfe-Bousquet-Patsiokas” combination renders claim 17 obvious for the reasons described in connection with Petitioner’s “Ground 1,” but to the extent that Wolfe does not render obvious the proposed construction of “acknowledgment” and re-transmission until an acknowledgment is received, Petitioner argues that Everett in combination with Wolfe, Bousquet, and Patsiokas meets those claimed limitations as proposed in “Ground 2.” Pet. 75. The two challenges are otherwise the same. Id. at 16–57, 73–78. For purposes of this Decision, we focus our analysis on Petitioner’s challenge that claim 17 is unpatentable under 35 U.S.C. § 103(a) as obvious over Wolfe, Bousquet, Everett, and Patsiokas (Ground 2). IPR2019-00510 Patent 6,868,079 B1 15 Claim 17 recites a “method of operating a radio communication system, comprising.”11 Petitioner contends that Wolfe describes a satellite communication system in which ground stations 10 and reference station 18 communicate over wireless satellite signals. Pet. 40 (citing Ex. 1005, 1:13– 2:9). Petitioner further contends, and we agree, that in Wolfe’s system, transmissions between the ground stations and the satellite occur at a radio frequency, and that a person having ordinary skill in the art would have found a satellite communication system operating at radio frequency to be a radio communication system. Id. (citing Ex. 1005, 7:23–28; Ex. 1003 ¶ 85). Petitioner explains, and we agree, that by describing a method of frame management for a satellite communication system operating at radio frequency, Wolf describes a “method of operating a radio communication system.” Id. Patent Owner does not dispute Petitioner’s showing with respect to Wolfe meeting the preamble of claim 17. See generally PO Resp. Claim 17 recites “allocating respective time slots in an uplink channel to a plurality of respective secondary stations.” Petitioner contends, and we find, that Wolfe describes a plurality of ground stations 10 (respective secondary stations) where each station is given a portion of a pre-allocated segment of a divided TDMA frame for uplink to satellite 12 (allocating respective time slots in an uplink channel). Id. at 41–43 (citing Ex. 1005, 1:13–2:9, 5:6–15, 5:34–46, 8:65–68, Figs. 1, 3; Ex. 1003 ¶¶ 86–87). Patent Owner does not dispute Petitioner’s showing with respect to Wolfe meeting this limitation. See generally PO Resp. 11 We need not resolve the issue of whether the preamble is limiting because, regardless of whether the preamble is limiting, Petitioner shows that Wolfe meets the preamble. IPR2019-00510 Patent 6,868,079 B1 16 Claim 17 recites “transmitting a respective request for services to establish required services from at least one of the plurality of respective secondary stations to a primary station in the respective time slots.” Petitioner contends, and we find, that Wolfe’s ground station 10 (secondary station) signals to reference station 18 (primary station) that a channel is required using its preallocated time slot. Id. at 43 (citing Ex. 1005, 5:6–15, 6:10–31.) Petitioner contends, and we agree, that Wolfe’s signal from ground station 10 to reference station 18 for additional capacity is a transmitted request for services to establish required services because the channel is required to complete a telephone call. Id. at 43–44 (citing Ex. 1005, 6:10–31). Petitioner explains that Wolfe’s ground station 10 forwards the received call request to reference station 18 as a connection request for allocation of an additional time slot in the overflow section. Id. Petitioner relies on annotated Wolfe Figure 3 to illustrate Wolfe’s description of ground station 10 transmitting a respective request for services to establish required services in the respective time slots, which results in reference station 18 allocating to a ground station 10 an overflow slot. Id. at 44–45 (citing Ex. 1005, Abstract, 1:8–11, 2:32–38, 4:47–57, 5:6– 15, 5:52–58, 6:10–50, 8:6–9, 8:55–68, Fig. 3; Ex. 1003 ¶¶ 88–92). We determine that Petitioner has shown sufficiently how Wolfe meets the limitation and Patent Owner does not dispute Petitioner’s showing. See generally PO Resp. Claim 17 recites “wherein the at least one of the plurality of respective secondary stations re-transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgement is received from the primary station.” Petitioner relies on Everett for its description of acknowledgments and re-transmission until an IPR2019-00510 Patent 6,868,079 B1 17 acknowledgment is received. Pet. 75; Reply 9 (“the proposed combination relies only on Everett’s concept of using acknowledgments and ceasing re- transmissions”). Petitioner relies on Bousquet in combination with Wolfe to meet “at least one of the plurality of respective secondary stations re- transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgment.” See e.g., Pet. 48–53; Pet. Reply 4. Petitioner contends, and we agree, that Everett describes a secondary station (VSAT) that receives an acknowledgment when a primary station (hub) acknowledges the request, which is separate from the primary station’s task of assigning a channel. Pet. 75 (citing Ex. 1008, 14, 337–339). We further agree with Petitioner that a person having ordinary skill in the art would have appreciated that Everett’s technique offered benefits to communication systems because Everett describes providing “the hub with the necessary control over VSAT transmissions and also prevents a VSAT . . . from repeatedly transmitting in an attempt to establish contact with the hub.” Id. (citing Ex. 1008, 207; Ex. 1003 ¶ 143). Petitioner contends, and we agree, that a person having ordinary skill in the art would have been motivated to implement Everett’s technique of sending acknowledgments in Wolfe’s satellite system, where bandwidth is limited, to prevent unnecessary continued re-transmissions and to further safeguard Wolfe’s system. Id. at 76–77 (citing Ex. 1008, 14, 207; Ex. 1005, 2:26–31; Ex. 1003 ¶¶ 145–146). It is not disputed that Everett describes sending acknowledgments to cease re-transmissions. PO Resp. 10. Patent Owner argues, however, that Everett fails to disclose re-transmitting the same respective request “in consecutive allocated time slots without waiting for an acknowledgment until said acknowledgment is received from the primary station.” PO Resp. 10 (emphasis in original), 12; see also Sur-reply 8–9. Petitioner does IPR2019-00510 Patent 6,868,079 B1 18 not rely on Everett alone to teach the entire phrase of “re-transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgment until said acknowledgment is received from the primary station.”12 Patent Owner’s argument (PO Resp. 10–11) that in Everett’s system, re-transmissions are done at randomly selected time intervals, which fails to meet the claimed “in consecutive allocated time slots” portion of the disputed phrase overlooks the challenge in its entirety. The Petition does not rely on Everett to show re-transmissions in consecutive time slots. Accordingly, we are not persuaded by Patent Owner’s arguments regarding Everett. Petitioner relies on Bousquet for its description of re-transmission of the same request without waiting for an acknowledgment. Pet. 48–49 (citing Ex. 1006, 2:48–60, 3:53–56; Ex. 1003 ¶ 97). In particular, Bousquet describes “each station requiring to set up a call should transmit at least two access packets without waiting for an acknowledgment between sending the access packets.” Ex. 1006, 2:48–53. According to Bousquet, re- transmission “is done within a time period less than that required for a round trip of a packet between the calling station and the called station.” Id. at 2:57–59. Bousquet further describes “systematic repetition of the access packets in the predefined time period therefore increases the probability that at least one of these packets will reach the destination station, which reduces the time necessary to set up a call.” Id. at 3:53–56. Although Bousquet describes that “[t]he n packets transmitted can be transmitted on the same carrier frequency and spaced in time, preferably at random,” Bousquet 12 See In re Keller, 642 F.2d 413, 426 (CCPA 1981) (“[O]ne cannot show non-obviousness by attacking references individually where, as here, the rejections are based on combinations of references.”). IPR2019-00510 Patent 6,868,079 B1 19 further describes that packets can be transmitted on different carrier frequencies “with a temporal distribution.” Id. at 3:57–61. Petitioner contends a person having ordinary skill in the art would have understood that Bousquet’s technique of reducing call setup time to be applicable to Wolfe’s TDMA system. First, Petitioner contends, and we agree, that both Wolfe and Bousquet describe satellite communication systems for handling call requests designed to support communications between a primary station and at least one secondary station. Pet. 25–27, 49 (citing Ex. 1005, 1:13–31; Ex. 1006, code (57), 1:12–21, 2:10–21). Petitioner further contends, and we agree, that it was known that long time delays were associated with transmissions in a satellite-based system. Id. at 27–28 (citing Ex. 1005, 3:65–4:14; Ex. 1006, 1:58–64). As explained above, Bousquet describes that (1) a station requiring to set up a call will transmit at least two access packets without waiting for an acknowledgment between sending the access packets, (2) re-transmission is done within a time period less than that required for a round trip of a packet between a calling station and a called station, and (3) systematic repetition of the access packets in the predefined time period increases the probability that at least one of the packets will reach the destination station, which reduces the time necessary to set up a call. Ex. 1006, 2:48–53, 2:57–59, 3:53–56. We agree with Petitioner that because “Bousquet describes that ‘[o]ther implementations are possible’ including transmission of packets with ‘temporal spacing,’” a person having ordinary skill in the art “would have found Bousquet’s techniques to be applicable [to] systems where packet transmission is ‘spaced in time,’ like transmissions of a TDMA system, such as Wolfe’s.” Pet. 50 (citing Ex. 1005, 1:1–15; Ex. 1006, 2:25– 28, 3:57–64; Ex. 1003 ¶ 99). We give substantial weight to Dr. Steffes’s IPR2019-00510 Patent 6,868,079 B1 20 testimony that a person having ordinary skill in the art “would have found it obvious to apply Bousquet’s approach to reduce call setup time even though Bousquet applies a contention-based approach to uplink signaling as compared to Wolfe’s contention-free system,” because his testimony is supported by Bousquet itself. Ex. 1003 ¶ 99 (citing Ex. 1006, 3:57–64, where Bousquet describes that packets can be transmitted on different carrier frequencies “with a temporal distribution” (emphasis added)). Based on the record before us, we determine that a person having ordinary skill in the art at the time of the invention would have understood that Bousquet’s technique of systematic repetition of transmitting a request from a secondary station to a primary station without waiting for an acknowledgment, thereby increasing the probability that at least one of the requests will reach the primary station, which reduces the time necessary to set up a call, would equally be applicable to Wolfe’s system. Ex. 1003 ¶ 99; Ex. 1006, 2:48–53, 3:53–56. Petitioner contends that it would have been obvious that in Wolfe’s modified system (with the teachings of Bousquet applied to Wolfe), re- transmission would have occurred in consecutive time slots (multiple slotted requests). Pet. 30 (citing Ex. 1003 ¶ 66), 50. In that regard, Dr. Steffes testifies as follows: Specifically, a POSITA13 would have found it obvious to modify Wolfe’s system to send multiple slotted requests within the timeframe for a roundtrip communication. A POSITA would have known that the typical round-trip delay for a satellite system at the relevant time was approximately 550 milliseconds (ms). EX1008, 317; EX1006, 4:6-11 (“a round trip between the stations that are to enter into communication, i.e. approximately 0.6 seconds for a geostationary orbit satellite.”); EX1005, 3:68- 13 Person of Ordinary Skill in the Art (“POSITA”). IPR2019-00510 Patent 6,868,079 B1 21 4:4 (“propagation of the request to the reference station 18 and of the reply to the requesting station 10…approaching 1 second”). Also, in Wolfe, “frames repeat often enough that a telephone conversation can be made to appear continuous and instantaneous.” EX1005, 1:45-47. It was well-known before the Critical Date that a frame repeating rate of one frame per every 150 millisecond, or less, was acceptable for voice signals under ITU recommendations. EX1011, 5 (ITU Standards). Accordingly, frames in Wolfe’s system repeat more quickly (every 150 ms) than the round-trip communication delay needed to receive acknowledgment of a request (550 ms). For example, based on a rate of one frame per every 150 ms and a round-trip delay of 550 seconds,14 a POSITA would have recognized that at least three packets may be sent within the typical satellite round- trip time frame. Because time slots in Wolfe are allocated at time intervals shorter than the round-trip delay, implementing Bousquet’s re-transmission technique by transmitting multiple requests in consecutive allocated time slots would have increased the probability that at least one request is received and reduced the time for call set-up. Ex. 1003 ¶ 66. Dr. Steffes explains, with supporting evidence, how and why a person having ordinary skill in the art would have combined Bousquet with Wolfe, resulting in re-transmitting the same respective request in consecutive allocated time slots without waiting for an acknowledgment. Id. For example, Dr. Steffes contends that in order to modify Wolfe’s system to send multiple requests within the timeframe for a roundtrip communication (e.g., to apply the teachings of Bousquet), a person having ordinary skill in the art would have known (1) the typical round-trip delay for a satellite system at the relevant time was approximately 550 milliseconds (ms) (Ex. 1006, 4:6–11); (2) that Wolfe’s frames in Wolfe’s system repeat more 14 We understand “550 seconds” should be “550 milliseconds.” IPR2019-00510 Patent 6,868,079 B1 22 quickly (every 150 ms) than the round-trip communication delay needed to receive acknowledgment of a request (550 ms) (Ex. 1011, 5 (ITU Standards); Ex. 1005, 1:45–47); and (3) based on a rate of one frame per every 150 ms and a round-trip delay of 550 milliseconds at least three packets may be sent within the typical satellite round-trip time frame, increasing the probability that at least one request is received and reducing the time for call set-up. Ex. 1003 ¶ 66. We give substantial weight to Dr. Steffes’s testimony that a person having ordinary skill in the art would have found it obvious to modify Wolfe’s system to send multiple slotted requests within the timeframe for a roundtrip communication, to increase the probability that at least one request is received, while reducing the time for call set-up, as taught by Bousquet which teaches packets transmitted on different carrier frequencies, with a temporal distribution. Id.; see also Ex. 1003 ¶ 69 (“a POSITA would have modified Wolfe to re-transmit requests in consecutive frames until a point in time when an acknowledgment of the first request would have been expected”).15 Patent Owner argues that Petitioner fails to show why a person having ordinary skill in the art would have combined the references “in a manner to re-transmit in even two ‘consecutive allocated time slots.’” PO Resp. 12– 13; Sur-reply 2. Patent Owner does not address Petitioner’s contentions, 15 We disagree with Patent Owner that Dr. Steffes’s testimony is conclusory and entitled to no weight and provides “only a hindsight reconstruction of the claim limitations, rather than an analysis based on a POSITA’s understanding of the references as a whole.” Sur-reply 7. Dr. Steffes’s testimony is well reasoned, is not based on hindsight reconstruction, and provides a basis for us to conclude that the particular facts to which he attests are more likely than not. IPR2019-00510 Patent 6,868,079 B1 23 supported by Dr. Steffes, to which we give substantial weight. For example, Patent Owner does not address Dr. Steffes’s testimony that a person having ordinary skill in the art applying Bousquet to Wolfe, would have known to transmit three packets (one packet per frame in the allocated time slot assigned to the secondary station)16 within the typical satellite round-trip time frame. Ex. 1003 ¶ 66. Dr. Steffes’s testimony stands unrebutted. He was not cross-examined and Patent Owner did not file any rebuttal testimony to show that Dr. Steffes is incorrect about how and why a person having ordinary skill in the art would have integrated Bousquet’s teachings into Wolfe’s system. Accordingly, we disagree that the combined teachings of Wolfe and Bousquet fail to meet the “re-transmits the same respective request in consecutive time slots without waiting for an acknowledgment.” Similarly, Patent Owner’s arguments attacking each of the Wolfe, Bousquet, and Everett references individually is unavailing because such arguments overlook the proposed challenge, which is based on the combined teachings of the references. For instance, Patent Owner argues that none of Wolfe, Everett, or Bousquet describes “wherein the at least one of the plurality of respective secondary stations re-transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgement is received from the primary station.” PO Resp. 7–11. Patent Owner’s arguments attacking each reference individually are unpersuasive, because the challenge is based on the combined teachings of Wolfe, Everett, and Bousquet as set forth in the Petition. For instance, Patent Owner argues that “because Bousquet limits 16 We note that the ’079 patent does not use the term “consecutive,” but references repeating a request (i.e., a packet) at a rate of once per frame or less. Ex. 1001, 4:8–12. IPR2019-00510 Patent 6,868,079 B1 24 its ‘repetition’ to ‘in the predefined time period,’ Bousquet cannot and does not disclose” the claimed re-transmission of “the same respective request ‘in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgement is received from the primary station.’” Id. at 9 (emphasis in original); Sur-reply 5. Patent Owner’s argument is not responsive to Petitioner’s showing, which also relies on Everett for its description of acknowledgments and re-transmission until an acknowledgment is received. Pet. 75; Reply 9 (“the proposed combination relies only on Everett’s concept of using acknowledgments and ceasing re- transmissions”). Thus, we are not persuaded by Patent Owner’s piecemeal approach, attacking each reference alone. See Keller, 642 F.2d at 426. Patent Owner further argues that because Bousquet discloses the systematic repetition of the access packets in a predefined time period, Bousquet teaches away from re-transmitting in consecutive time slots as claimed. PO Resp. 8–9; Sur-reply 3–4. Patent Owner fails to explain why Bousquet’s description of systematic repetition of access packets in a predefined time period even matters insofar as the claim language is concerned. We agree with Petitioner that there is nothing in claim 17, for example, that precludes re-transmissions in a predefined time period, and Patent Owner has not shown with supporting evidence, for example, otherwise. Pet. Reply. 22. Accordingly, we disagree that Bousquet teaches away from the claimed invention. Patent Owner argues that Petitioner fails to reconcile Everett’s allegation of acknowledgment processing with Bousquet, which teaches re- transmission of requests independent of whether an acknowledgment is received or not. Sur-reply 10. We disagree. Petitioner explains that to limit unnecessary consumption of bandwidth, it would have been obvious to a IPR2019-00510 Patent 6,868,079 B1 25 person having ordinary skill in the art that further re-transmissions would have been avoided upon receipt of acknowledgment of an earlier request. Pet. 31–32 (citing Ex. 1003 ¶ 69), 76–77 (citing Ex. 1008, 10; Ex. 1003 ¶ 145). Petitioner contends, and we agree, that a person having ordinary skill in the art would have been motivated to implement Everett’s technique of sending acknowledgments in the combined Wolfe-Bousquet satellite system, where bandwidth is limited, to prevent unnecessary continued re- transmissions and to further safeguard the system. Id. at 76–77 (citing Ex. 1008, 14, 207; Ex. 1005, 2:26–31; Ex. 1003 ¶¶ 145–146). It would have been obvious to a person having ordinary skill in the art that once the uninterrupted consecutive requests are received from the primary station (taught by the Wolfe-Bousquet satellite system), the primary station sends to the secondary station an acknowledgment of receipt, as taught by Everett to prevent unnecessary continued re-transmissions and to safeguard the system as explained by Dr. Steffes. Ex. 1003 ¶¶ 145–146. Again, we give Dr. Steffes’s unrebutted and factually supported testimony substantial weight. Patent Owner did not file testimony of its own to rebut Dr. Steffes’s testimony to show, for example, that he is incorrect about how and why a person having ordinary skill in the art would have integrated Everett’s teachings into the Wolfe-Bousquet system. Claim 17 recites “wherein the primary station determines whether a request for services has been transmitted by the at least one of the plurality of respective secondary stations by determining whether a signal strength of the respective transmitted request of the at least one of the plurality of respective secondary stations exceeds a threshold value.” Petitioner explains that in Patsiokas, the primary station uses a predetermined threshold measurement to ascertain the received signal strength (“RSS”) level of the IPR2019-00510 Patent 6,868,079 B1 26 received signal and compares the RSS level to a threshold level before the primary station allocates a communication channel in response to the request. Pet. 53 (citing Ex. 1007, 2:11–21). Petitioner contends, and we agree, that Patsiokas’s description of “the base site detects channel request signals having an RSSI level at or above a first threshold” before granting a communication link in combination with the Wolfe-Bousquet-Everett system, meets the above identified limitation. Id. at 53–55 (citing Ex. 1007, 2:11–21, 4:27–5:3, Fig. 3; Ex. 1003 ¶ 110). While Patent Owner argues that it would not have been obvious to combine Patsiokas with the Wolfe- Bousquet-Everett system, Patent Owner does not contest that the combination of the references meets the last wherein limitation. See generally PO Resp. Petitioner sets forth reasoning with rational underpinnings as to why a person having ordinary skill in the art would have combined the teachings of Wolfe, Bousquet, Everett, and Patsiokas. Pet. 37–40, 55–57, 74–78 (citing multiple passages from Ex. 1005, Ex. 1007, and Ex. 1003). Petitioner explains that like Wolfe’s system, Patsiokas’s system employs a channel acquisition method and includes a primary station with an ability to independently detect a request for a service as well as allocate a channel to a plurality of secondary stations, and that it would have been obvious for a person having ordinary skill in the art to look at other communication systems having similar functions. Id. at 55 (citing Ex. 1007, 1:36–2:1, Fig. 3; Ex. 1005, 5:20–21; Ex. 1003 ¶ 111). Notwithstanding Patent Owner’s arguments that Patsiokas is not relevant to the claimed invention, which we address next, we are persuaded that Petitioner has shown, by a preponderance of the evidence that Patsiokas is relevant to the claimed invention. IPR2019-00510 Patent 6,868,079 B1 27 Patent Owner argues that “[a] POSITA would not have made any of the hypothetical combinations proposed by the Petition involving Patsiokas because, unlike Wolfe, Bousquet, and Everett, which are satellite systems, Patsiokas relates to ‘second generation cordless telephone (CT2)’ radio telephones.” PO Resp. 13–14 (citing Ex. 1007, 1:15–2:8). We are not persuaded by this argument. Patent Owner directs us to no evidence in support of its assertions as to what a person having ordinary skill in the art would have known at the time of the invention. See Estee Lauder Inc. v. L'Oreal, S.A., 129 F.3d 588, 595 (Fed. Cir. 1997) (argument of counsel cannot take the place of evidence lacking in the record). Here for example, we do not have before us a declarant on behalf of Patent Owner to inform us what a person having ordinary skill in the art would have known at the time of the invention or that such person would not have considered Patsiokas relevant to the claimed invention. We cannot take the unsworn word of an attorney, who, on this record has not been shown to be a person having ordinary skill in the art. On the other hand, Petitioner has provided a declarant, whom we find is qualified to testify on the matters before us. See, e.g., Ex. 1003 ¶¶ 1–17. Dr. Steffes testifies as follows: [L]ike Wolfe’s system, Patsiokas’[s] system employs a channel acquisition method and includes a primary station with an ability to independently detect a request for a service as well as allocate a channel to a plurality of secondary stations. EX1007, 1:36- 1:33-2:1 (“each base site is monitoring the channels of the CT2 system independently”), FIG. 3; EX1005, 5:20-21 (“[t]wo independent reference stations”). It would have been obvious to a POSITA to look at other communication systems having similar functions. Id. ¶ 111. Dr. Steffes testifies that like Wolfe’s system, Patsiokas’s system employs a channel acquisition method and includes a primary station with IPR2019-00510 Patent 6,868,079 B1 28 an ability to independently detect a request for a service as well as allocate a channel to a plurality of secondary stations. Id. We give his testimony substantial weight that a person having ordinary skill in the art would have looked to communication systems with similar functions. Id. Patent Owner’s attorney argument that a person having ordinary skill in the art would not have looked to radio telephone systems such as Patsiokas’s fails to take into account the evidence of record. Moreover, claim 17 broadly recites “[a] method of operating a radio communication system.” Ex. 1001, 8:11. We find both satellite systems such as Wolfe’s and terrestrial systems such as Patsiokas’s to fit within the broad category of a “radio communication system.” Ex. 1005, 7:23–28 (“RF transmission frequency”); Ex. 1003 ¶ 85 (explaining that a POSITA would have found a satellite communication system operating at radio frequency to be a radio communication system); Ex. 1007, 1:15–16 (invention relates to “radio telephone communication systems”). For all of these reasons, we are persuaded that Petitioner has shown, by a preponderance of the evidence, that Patsiokas is relevant to the claimed invention. Petitioner argues, and we agree, that “a POSITA would have been motivated to implement Patsiokas’[s] signal threshold method in the Wolfe- Bousquet communication system because this allows the primary station to allocate a channel to secondary stations that are unlikely to drop calls.” Pet. 38 (citing Ex. 1007, 4:34–36). Petitioner explains that by measuring signal-strength related parameters of incoming requests, the primary station assesses whether the communication channel allocated to calls would have a signal strength sufficient for successfully connecting the calls, taking into account weather conditions and signal interference. Id. (citing Ex. 1007, 4:34–36; Ex. 1008, 303–304, 424–428; Ex. 1009, 1; Ex. 1010, 2:20–27; IPR2019-00510 Patent 6,868,079 B1 29 Ex. 1003 ¶ 82). Petitioner further argues, and we agree, that a “POSITA also would have been motivated to implement Patsiokas’[s] signal threshold method in the Wolfe-Bousquet communication system because the primary station’s maximum sensitivity level is applicable and relevant to establishing and maintaining a reliable call connection in a satellite system, such as Wolfe’s system.” Id. at 55–56 (citing Ex. 1003 ¶ 112). Notwithstanding Patent Owner’s arguments, addressed below, we are persuaded that Petitioner has shown, by a preponderance of the evidence, that a person having ordinary skill in the art would have been motivated to implement Patsiokas’s signal threshold method in the Wolfe-Bousquet-Everett communication system. Patent Owner argues, “Patsiokas addresses a shortcoming in cordless radio telephone systems that is not identified or present in the satellite systems of Wolfe, Bousquet, and Everett, and therefore, a POSITA would not have been motivated to make the proposed combinations with Patsiokas.” PO Resp. 14. In particular, Patent Owner argues that the shortcoming identified in Patsiokas is that when a user moves out of range of a base station, a communications link will be dropped. Id. at 16 (citing Ex. 1007, 3:12–25). Patent Owner argues that that problem does not exist in any of the Wolfe, Bousquet, or Everett, because satellite systems do not suffer from range issues, and, therefore “a POSITA would not have been motivated to make the hypothetical combinations involving Patsiokas, at least because there is no concern of a user walking out of range of the base station in satellite systems.” Id. at 16–18. As explained in the Petition, in both radio telephone systems such as Patsiokas’s and satellite systems such as Wolfe’s, the problem of a communication link deteriorating and/or failing was known. Pet. 39, 56–57. IPR2019-00510 Patent 6,868,079 B1 30 Patsiokas describes that a “base site that grants the channel request is not necessarily the one closest to the radio telephone unit transmitting the channel request signal” and that the “user may move out of range of the base site, thus causing the communication link to be dropped.” Ex. 1007, 1:35– 2:3. Satellite systems like Wolfe’s also suffered from signal deterioration or failing (e.g., dropped calls) due to weather and interference issues. Ex. 1008, 303–304 (“losses of data caused by atmospheric attenuation”), 424–428 (“signal strength . . . reduced by . . . water vapor”); Ex. 1009, 1 (“disadvantages of the satellite system are . . . the effect of local weather conditions and interferences”): Ex. 1010, 2:20–27 (“rain fade is a serious problem”). Patent Owner does not dispute that signal deterioration or failure was a problem in both satellite and telephone (terrestrial) systems. Rather than focus on the known problem of a communication link deteriorating and/or failing, Patent Owner narrowly focuses on the reason why, in Patsiokas, the communication link deteriorates or fails. Whether a signal is deteriorating and/or failing because a user is nearly out of range of a base station versus whether a signal is deteriorating and/or failing because of interference or weather related issues has not been demonstrated to be of concern to a person having ordinary skill in the art at the time of the invention. Dr. Steffes’s testimony focuses on the problem in both satellite and telephone (terrestrial) systems of a communication link deteriorating and/or failing (dropped calls). We give substantial weight to Dr. Steffes’s testimony that “a POSITA would have been motivated to implement Patsiokas’s signal threshold method in the Wolfe-Bousquet communication system because this allows the primary station to allocate a channel to secondary stations that are unlikely to drop calls.” Ex. 1003 ¶ 82. We IPR2019-00510 Patent 6,868,079 B1 31 further give Dr. Steffes’s testimony substantial weight that the “teachings in Patsiokas would have therefore been applicable to the Wolfe system, because the initial connection is indicative of the likelihood of dropped calls in a channel connection over the call time duration.” Id. Patent Owner’s attorney argument that “a POSITA would not have been motivated to make the proposed combinations” is not supported by record evidence. PO Resp. 14. Again, Patent Owner could have presented a declaration from an expert who could have opined as to what a person having ordinary skill in the art would have known at the time of the invention. Here, however, Patent Owner’s attorney is the one arguing to us what a person having ordinary skill in the art would or would not have done, without evidence that Patent Owner’s attorney is a person having ordinary skill in the art. Accordingly, we are not persuaded by Patent Owner’s attorney arguments. For all of these reasons, we are persuaded that Petitioner has shown, by a preponderance of the evidence, that a person having ordinary skill in the art would have combined the teachings of Wolfe, Bousquet, Everett, and Patsiokas. Id. at 37–40, 55–57, 74–78 (citing multiple passages from Ex. 1005, Ex. 1007, and Ex. 1003). Accordingly, for the reasons given above, having considered Petitioner’s and Patent Owner’s arguments and evidence, we determine that Petitioner has shown by a preponderance of the evidence that claim 1 of the ’079 patent would have been obvious over Wolfe, Bousquet, Patsiokas, and Everett. C. Remaining Ground Challenging Claim 17 of the ’079 Patent For the reasons discussed above, Petitioner has shown, by a preponderance of the evidence, that claim 17 of the ’079 patent is unpatentable as obvious over Wolfe, Bousquet, Patsiokas, and Everett. In IPR2019-00510 Patent 6,868,079 B1 32 addressing this ground, we have addressed the challenged claim. See 35 U.S.C. § 318(a) (requiring the Board to “issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner and any new claim added under section 316(d)”); see also SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1359 (2108) (holding that a petitioner “is entitled to a final written decision addressing all of the claims it has challenged”). Accordingly, we need not and do not decide whether Petitioner has shown by a preponderance of the evidence that claim 17 also would have been obvious based on Wolfe, Bousquet, and Patsiokas. Cf. In re Gleave, 560 F.3d 1331, 1338 (Fed. Cir. 2009) (not reaching other grounds of unpatentability after affirming the anticipation ground); see also Beloit Corp. v. Valmet Oy, 742 F.2d 1421, 1423 (Fed. Cir. 1984) (holding that once a dispositive issue is decided, there is no need to decide other issues). III. CONCLUSION17 For the foregoing reasons, we determine that Petitioner has shown by a preponderance of the evidence that claim 17 of the ’079 patent is unpatentable, as summarized in the following table: 17 Should Patent Owner wish to pursue amendment of the challenged claim in a reexamination proceeding subsequent to the issuance of this Decision, we draw Patent Owner’s attention to the April 2019 Notice Regarding Options for Amendments by Patent Owner Through Reissue or Reexamination During a Pending AIA Trial Proceeding. See 84 Fed. Reg. 16654 (Apr. 22, 2019). If Patent Owner chooses to file a request for reexamination of the challenged patent, we remind Patent Owner of its continuing obligation to notify the Board of any such related matters in updated mandatory notices. See 37 C.F.R. § 42.8(a)(3), (b)(2).

ORDER Accordingly, it is: ORDERED that claim 17 of the ’079 patent has been shown to be unpatentable; and FURTHER ORDERED that, because this is a Final Written Decision, parties to the proceeding seeking judicial review of the Decision must comply with the notice and service requirements of 37 C.F.R. § 90.2. 18 As explained immediately above, we need not and do not decide whether Petitioner has shown by a preponderance of the evidence that claim 17 also would have been obvious based on Wolfe, Bousquet, and Patsiokas.
