  PTAB · Oct 22, 2015 · IPR2014-00963 · APJ David C Mckone · IPR · Final written decision

  Claims 1–16 were not shown unpatentable because the ’480 patent did not disclose frequency hopping and the proposed obviousness combination lacked a reasonable expectation of success.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for petitioner

    “In the Decision to Institute, in light of an agreement between the parties, we preliminarily determined that “broadband transceiver,” recited in claim 1, means “a transceiver that covers a substantial portion of the bandwidth available to the wireless service provider who is operating the basestation,” with the clarification that such a transceiver does not include a set of single-frequency transceivers. Dec. 10. Neither party contests this construction. On the complete record, we maintain this construction. We further determined that no other claim term required express construction. Dec. 10. Neither party proposes a construction of any other term and we find it unnecessary to construe any other term to resolve the dispute between the parties.” slip op. at 8

  • Skill levelSkill level board ownDecided for petitioner

    “1. Level of Skill in the Art Petitioner contends that a person of ordinary skill in the art would have had at least a B.S. degree in Electrical Engineering, Computer Engineering, or the like, and at least three years of additional academic or industry experience. Pet. 11 (citing Ex. 1003 (Stark Decl.) ¶ 45). Dr. Wells “generally agree[s] with Dr. Stark in paragraph 45 of his declaration.” Ex. 2007 ¶ 20. We adopt the parties agreed statement of the level of skill of a person of ordinary skill in the art.” slip op. at 21

  • Expert testimonyPetitioner expert discountedMixed

    “Dr. Stark’s testimony also is not supported by the description in the ’480 patent. In one example, Dr. Stark testifies that: For the case of the receiver side (dehopping) as shown is Fig. 3, the same logical channel would “hop” onto different RF channels each successive GSM TDMA frame. This would mean that for a particular TDMA frame, a given logical channel, e.g., channel 1 on slot 1, would be at a particular RF channel such as indicated by location “27” in the table in Fig. 3. But in the next TDMA frame, the same logical channel, would be placed onto a different RF channel, e.g., location “2” in the table in Fig. 3. By the controller supplying a new mapping signal (table) every TDMA frame, the samples from the correct RF channel for the associated logical channel could be placed onto the TDM bus for processing by the corresponding DSP 18. Ex. 1022 ¶ 17. This is inconsistent with the description in the ’480 patent. Locations “27” and “2” in DP RAM Enable 202 merely indicate whether data can be asserted into time slots 27 and 2. Ex. 1006, 9:46–10:3. Changing the mapping in DP RAM Enable 202 to enable slot “2” and disable slot “27,” without additional changes elsewhere in the system, would not result in different RF channels being switched to the same logical channel. In this example, and the others cited above, Dr. Stark repeatedly testifies that simply re-programming DP RAM Enable 202 will change the mapping of physical RF channels and logical channels. Nevertheless, as Patent Owner argues (PO Resp. 26–27), the ’480 patent does not support that testimony. Because Dr. Stark’s testimony is inconsistent with the description in the ’480 patent, we give his testimony little weight.5” slip op. at 28

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable

    “(Ex. 1006, 5:4–17) describes a basestation’s exchange of RF signals with mobile subscriber terminals. Specifically, the passage is directed to the modulation of voice and data channels over RF carrier signals: “The RF carrier signals are modulated with voice and/or data (channel) signals which are to be coupled to the public switched telephone network (PSTN) by the basestation 10.” Ex. 1006, 5:6–9 (emphasis added). In that context, the ’480 patent explains that “[t]he particular modulation in use[] may be any one of a number of different wireless (air interface) standards such as the well known Advanced Mobile Phone Service (AMPS), time division multiple access (TDMA) such as IS-54B, code division multiple access (CDMA) such as IS-95, frequency hopping standards such as the European Groupe Speciale Mobile (GSM).” Id. at 5:9–17 (emphases added). We find that this passage states, at most, that the system described in the ’480 patent supports the modulation specified by the GSM standard. Petitioner admitted at the hearing that frequency hopping is not a modulation scheme and that GSM specifies the same modulation scheme whether or not frequency hopping is used. Tr. 62:17–63:23. The passage of column 5, lines 9–17, of the ’480 patent is consistent with the system of the ’480 patent being programmed to support the modulation scheme of GSM, without supporting the optional frequency hopping functionality. While GSM is referred to as a “frequency hopping standard[],” the frequency hopping functionality is inapposite to the modulation being discussed in the passage. Tr. 63:17–22 (“JUDGE McKONE: And you can use the same modulation regardless of whether you are using frequency hopping or not, is that right? MR. SPEARS: Exactly. Yeah, it’s the same slot. It’s the same framing. It’s the same TDMA frames. It is all the same.”). We find that the ’480 patent does not state, explicitly or implicitly, that the described system implements the optional frequency hopping functionality of GSM. We recognize that Dr. Stark testifies that “a [person of ordinary skill in the art] would have understood that explicit reference to GSM to include reference to the constituent part of the GSM standard that specifies frequency hopping, i.e., GSM 05.02, and thus a [person of ordinary skill in the art] would understand that the ʼ480 Patent discloses this limitation as described below.” Ex. 1003 ¶ 90. Dr. Stark’s testimony, however, relies on his assumption that frequency hopping is a type of modulation. Id. As noted above, Petitioner has conceded that frequency hopping is not a type of modulation. Accordingly, we do not credit Dr. Stark’s testimony on this point. At the hearing, Petitioner argued that “there is no reason to say you are doing frequency hopping unless you are frequency hopping.” Tr. 63:22– 23. We are not persuaded. The ’480 patent does not state that its system is “doing frequency hopping.” Rather, it characterizes GSM as a “frequency hopping standard[].” While this characterization may be relevant to obviousness (discussed below), it is not a statement explicitly showing that the system of the ’480 patent implements frequency hopping.” slip op. at 17
