    “Although Patent Owner contends Dr. Goodnick’s declaration did not open the door for general questioning about metal oxides (PO Opp. 2–3), we agree with Petitioner that the proper scope of cross examination includes Dr. Goodnick’s understanding of what constitutes a distinct layer. A primary issue raised by Patent Owner against Petitioner’s challenge that Goodnick anticipates is that, notwithstanding its use of the term layer, Goodnick does not teach distinct layers that are required by the claim. See Section VI.B. One of those layers is a metal oxide layer (Ex. 1101, claim 1), in particular a titanium oxide layer (claim 6). In view of Dr. Goodnick’s checkerboard analogy in his declaration, it was proper for Petitioner to question Dr. Goodnick about the extent of materials in the checkerboard. Both parties argue there may be implications of Dr. Goodnick’s testimony for purposes of infringement litigation. See Pet. Opp. 4–6; PO Reply 3–4. We do not address those implications. The issue before us is whether Goodnick would have taught or suggested to a person of ordinary skill the limitations of the claims, which the parties agree include distinct layers of metal oxide and other semiconductor oxide. See Section VI.B. As Dr. Goodnick testified that his article did not teach such distinct layers, it was proper for Petitioner to explore Dr. Goodnick’s views concerning the composition of a layer during cross examination. In consideration of the above, Patent Owner’s motion to exclude the Goodnick Metal Oxide testimony is denied.” slip op. at 48

    “Taken in context, we agree that a person of ordinary skill would have understood Goodnick to refer to Al2O3 as a distinct layer. Referring to Fig. 8(a), Goodnick states that in an unheated sample with an air grown oxide “[i]t appears that Si has diffused into the Al and collected at the Al2O3- Al interface at the surface. No buildup of Al2O3 is seen at the Al-Si interface.” Ex. 1116, 953. Noting that Fig. 8(b) is a profile of an unheated sample with 30Å of SiO2 at the interface, Goodnick states “[i]n contrast to the air exposed sample, an Al2O3 layer exists at the Al-SiO2-Si interface.” Id. Petitioner notes that, on cross examination, Dr. Goodnick acknowledged (i) that the Al metal layer would diffuse into the SiO2 interface layer and reduce the portion of the SiO2 layer nearest the Al layer to Al2O3, (ii) that once the Al2O3 layer forms, it would be difficult for aluminum atoms to diffuse through the Al2O3 layer to continue reaction with the SiO2 layer, and (iii) because the reaction is self-limiting, a portion of the original SiO2 layer would remain once the reaction forming the Al2O3 layer stopped. Pet. Reply 5–6 (citing Ex. 1168, Goodnick Tr. 55:5–25, 57:19– 58:8, 59:24–60:7).

Pet. 27. According to Petitioner, a person of ordinary skill would have combined the teachings of Goodnick and Jammy because Goodnick describes contact metallization processes for semiconductor devices and Jammy describes a semiconductor device. Id. at 28. Patent Owner asserts that Petitioner’s challenge to claim 4 based on the combined teachings of Goodnick and Jammy fails because it is premised on Goodnick teaching a stratified layer of Al2O3 distinct from SiO2.

In consideration of the above, we find that Petitioner has demonstrated by a preponderance of the evidence that a person of ordinary skill would have had reason to combine the teachings of Goodnick and Jammy and that the combined teachings of Goodnick and Jammy would have suggested the limitations of claim 4 to a person of ordinary skill in the art.” slip op. at 24

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “The principal difficulty with Patent Owner’s arguments is that they improperly conflate transferring desktop information with the claim’s 4 The ’288 patent instead uses the uncommon acronym “PAUNTSC,” presumably a result of incorrectly printing “L/” as “U.” recitation of “capturing” desktop information. Indeed, Dr. Bhattacharjee concedes that “the desktop information as described in the ’288 patent is transferred in digital form,” even as he maintains his opinion that desktop information is not limited to digital capture by the ’288 patent. Ex. 1020 ¶ 11. There is thus no dispute among the expert witnesses, nor the parties, that the ’288 patent describes the digital transfer of desktop information. As Dr. Bhattacharjee explains, this is a consequence of the fact that “the [’288] patent describes and claims transferring desktop information only after it is encoded.” Ex. 1020 ¶ 12. Because such encoding occurs only after the desktop information is captured, “the captured desktop information could either be digital or analog.” Id. The aspects of the intrinsic record that Patent Owner identifies as supporting its proposed construction are, in fact, consistent with this distinction between capture and transfer. For example, the “advantage of the invention” identified by Patent Owner is specifically described by the ’288 patent as raising clarity on the video communication terminal when “[d]esktop information of a PC is transferred directly in a digital coded bit stream mode without converting digital signal to analog signal.” See Ex. 1001, 2:35–39 (emphasis added). This is, moreover, consistent with the portion of the prosecution history Patent Owner identifies and which also makes clear that “the desktop information of a PC is transferred in a digital coded bit stream.” Ex. 1002, 159 (emphasis added). Petitioner’s expert, Dr. Bhattacharjee “agree[s] the desktop information as described in the ’288 patent is transferred in digital form,” even though it is not captured in digital form.

    “skill in the art] would be motivated to combine even when bandwidth is shared”: (1) “the shared nature of the bandwidth only highlights that reduced bandwidth usage for desktop information provides the capability of a higher quality signal for the live stream without any extra costs in components or processing”; (2) because Kenoyer ’423 “does not disclose using a dedicated or fixed amount of bandwidth . . . , any reduction in bandwidth would reduce overall usage”; and (3) “even in a dedicated environment, Kenoyer ’423’s reduced bandwidth needs for desktop information would reduce the amount of dedicated bandwidth that is required, potentially saving costs or power.” Reply 12 (citing Ex. 1020 ¶¶ 31–32). These reasons are directly responsive to arguments raised by Patent Owner in its Response and are therefore properly considered. See 37 C.F.R. § 42.23(b). We also find such reasons, which are supported by additional testimony by Dr. Bhattacharjee, adequately explain how Patent Owner’s distinction is accommodated within Petitioner’s expressed rationale of “minimizing bandwidth usage.” See Ex. 1020 ¶¶ 31–32. Second, Patent Owner contends that, if “Kenoyer ’423 were interpreted as teaching reducing bandwidth, it does so in a different manner than in Becker.” PO Resp. 37. Specifically, “Becker addresses bandwidth reduction by using signal compression techniques,” Patent Owner says, while “Kenoyer ’423 prevents the increase in bandwidth . . . by dynamically sharing bandwidth when both a live view of the presenter and the presenter’s computer screen are being shared.” Id. Dr. Bhattacharjee disputes this distinction by observing that Kenoyer ’423’s technique still “reduces the number of bits required to convey the same video information,” and is thereby broadly encompassed as a form of “signal compression.” Ex. 1020 ¶ 33. Dr. Rosing does not specifically disagree with Dr. Bhattacharjee’s characterization. See generally Ex. 2022 ¶ 99. Regardless, both Becker and Kenoyer ’423 support Petitioner’s rationale of “minimizing bandwidth usage.” Patent Owner inadequately explains how a distinction in the precise manner that might be accomplished by the two references diminishes the support provided by the rational underpinnings identified by Petitioner. See PO Resp. 37 (Patent Owner making the conclusory statement that “[a]s such, Petitioner fails to provide a valid motivation for combining Becker and Kenoyer ’423”).” slip op. at 26

    “After this proceeding was remanded by the Federal Circuit, we invited the parties to address a proposed procedure that would include additional briefing regarding the impact of the prior holdings that claims 1–3, 5, and 10–20 are unpatentable, and the parties filed their respective proposals. Papers 78–80. In its proposal, Petitioner suggested that Patent Owner “has waived the right to address the patentability of claims 4, 8, and 9” because “Patent Owner never separately argued for the patentability of these claims.” Paper 79, 1; see MaxLinear, 880 F.3d at 1378 n.4 (“On remand, the Board may consider whether CRESPE has waived arguments concerning these claims.”). But those claims were not challenged in the earlier proceedings that held claims 1–3, 5, and 10–20 unpatentable. Rather, those claims were only challenged in this proceeding with respect to art that was not at issue in the earlier proceedings. In advancing its contention, Petitioner effectively makes the untenable argument that Patent Owner must provide separate reasons for the patentability of claims 4, 8, and 9, even when we determine that its own case-in-chief for those claims is insufficient. In addition, Petitioner’s proposal requests briefing on the issues of “whether claims 6, 7 and 20 materially alter the [unpatentability] analysis on which the prior [unpatentability] determinations rested.” Id. We have considered, and deny, that request. The Federal Circuit’s remand order noted that the fact that “MaxLinear was not a party to the other IPRs is . . . irrelevant since Cresta, the predecessor in interest to CRESPE, was party to the original determination.” MaxLinear, 880 F.3d at 1377. But the Federal Circuit’s order does not state or suggest that the fact that different prior art was considered in the earlier proceedings is similarly irrelevant. Indeed, we agree with Patent Owner that “[t]he Federal Circuit has not ordered the Board and the parties to start over from scratch, and certainly not with new prior art.” Paper 80, 3; see Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015) (“The Board may control its own proceedings, consistent with its governing statutes, regulations, and practice.”). Patent Owner is correct that “[a]llowing new prior art to be considered on remand after the Final Decision on the merits would essentially be starting a new IPR proceeding.” Paper 80, 9. As Patent Owner asserts, “[t]he parties and the Board would have to argue and consider new grounds, new expert testimony would have to be taken and presented, and a new Final Decision would have to be rendered.” Id. The Federal Circuit’s instruction is limited: “We remand this case to the Board so that it may consider the patentability of the surviving disputed dependent claims 4, 6-9, and 21.” MaxLinear, 880 F.3d at 1378. We have complied with this instruction in two ways: first, by applying the Federal Circuit’s instruction regarding the collateral-estoppel impact on challenged claims 1–3, 5, and 10–20; and, second, by clarifying that Petitioner’s argument regarding the combination of Van De Plassche and Ishikawa compels a conclusion that Petitioner’s showing is insufficient with respect to claims 4, 6–9, and 21, independent of any conclusion previously reached with respect to independent claims 1 and 17. While the Federal Circuit includes language in its remand order that might be construed as suggesting applying different prior art in the latter analysis, 880 F.3d at 1377, the scope of this proceeding is limited by the prior art and the arguments in the Petition here.

    “Experience is but one of several factors that may be considered when determining the level of ordinary skill in the art. See, e.g., In re GPAC, 57 F.3d 1573, 1579 (Fed. Cir. 1995) (identifying factors as 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 a given case, every factor may not be present, and one or more factors may predominate.” Id. Patent Owner’s distinction relates to a portion of one factor (education) in a determination that involves several factors. The significance of the level of ordinary skill in the art is the role it plays in an obviousness analysis. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Patent Owner does not explain persuasively how the alleged omission by Petitioner impacts the obviousness analysis.

    “Importantly, we find that Patent Owner did not exhaust avenues available to it in attempting to secure answers to its questions from Dr. Hashemi. The line of questioning involving Exhibit 2008 occurred late in the day, “well after the close of business on the east coast,” and an attempt by the parties to telephone the Board during the deposition was unsuccessful. See Opp. 3; Ex. 2006, 154:24–155:4. The parties discussed contacting the Board the following day, and continuing the deposition the day after that, when Petitioner would make Dr. Hashemi available for further cross-examination after receiving guidance from the Board. Ex. 2006, 155:5–157:13. Rather than proceed in this fashion, Patent Owner decided to abandon the line of questioning and passed the witness for redirect: “I think after we talked about it a bit, I think we will withdraw our questions on this document and just move on to redirect.” Id. at 157: 22–25 (emphasis added). Dr. Hashemi could have answered the questions and sought a protective order that would insulate his answers from the public record, providing the Board with the information needed to perform a focused evaluation of the credibility and reliability of specific statements in his testimony. But a significant measure of responsibility for whether Dr. Hashemi’s testimony is tainted with bias lies with Patent Owner for declining to pursue the issue to a point of greater clarification. Indeed, we are limited in how strongly we can fault Petitioner for failing to submit a clarifying declaration from Dr. Hashemi, in light of Patent Owner’s decision to “withdraw” the questions at issue. Because the evidence is insufficiently developed, we are similarly limited in the degree to which we can draw adverse inferences from Dr. Hashemi’s refusal to answer questions, and unable to conclude, by a preponderance of the evidence, that Dr. Hashemi’s testimony is tainted by an undisclosed bias.

    “time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere Co, 383 U.S. 1, 17 (1966). Petitioner contends a person of ordinary skill in the art at the time of the alleged invention of the ’315 patent (a “POSITA”) would have had at least a bachelor’s degree in electrical, electronics, or computer engineering, or the equivalent training or experience in electrical, electronics, or computer engineering, or a related discipline, and would have had approximately 2 to 3 years of experience in computer systems, circuits, electronics, or a related discipline. Pet. 16. Petitioner’s declarant, Dr. Bagherzadeh, generally agrees with this proposed level of ordinary skill in the art, but states that a POSITA would have had two or more years of experience in computer hardware, including the use of computer memory, and that the two or more years of experience would provide practical experience required to address issues such as low power backup for volatile memories. Ex. 1002 ¶¶ 31–32. Patent Owner does not contest Petitioner’s description of the level of ordinary skill in its Response. See PO Resp. 8. Based on our review of the ’315 patent, the cited prior art, and Dr. Bagherzadeh’s testimony, we determine a specific finding regarding ordinary skill level is not required as the prior art reflects an appropriate level. However, to the extent a specific finding regarding the level of skill is required, we adopt Dr. Bagherzadeh’s description of a POSITA as it is consistent with the teachings of the prior art.

    “We agree with Petitioner (Pet. Reply 8–9), however, that an ordinarily skilled artisan would not have read Chou as narrowly as Patent Owner contends. Not only does Chou state that its fixture “may be configured to be installed into a recessed can housing having other geometries,” but also “recessed housings . . . developed with different geometries.” Ex. 1012, 3:65–4:7 (emphasis added). In light of this express teaching in Chou, we do not agree that Chou’s teachings are confined to 5- and 6-inch can lights, or even can lights in general. Junction boxes represent another geometry that can serve as a recessed housing for an LED light fixture. See Ex. 1023, 30:17–31:7 (Dr. Bretschneider testifying that, by 2009, LED light fixtures attached to junction boxes were known with “certain parts” inside the box). In addition, the fact that certain figures of Chou might depict a junction box external to a can light does not mean that junction boxes are excluded from the universe of “recessed housings” contemplated in the quotation above. In addition, Patent Owner contends Petitioner has provided no reason or motivation to combine Wegner with Chou. PO Resp. 10–11. Patent Owner also contends an ordinarily skilled artisan would not have combined Wegner with Chou because Wegner pertains to a light with a tall reflector, which must be installed in a can light fixture (and not a junction box). Id. at 11–12 (citing Ex. 2001 ¶¶ 74–75, 133–137). Yet Petitioner only cites Wegner for its teaching of removing an Edison base from an LED light fixture to facilitate direct wiring, and not for anything to do with reflectors. Pet. 24 (citing Ex. 1002 ¶ 53; Ex. 1016, 11:3–32). As such, Patent Owner’s arguments regarding Wegner’s light reflectors amounts to a bodily incorporation argument, which is not the test for obviousness. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.”). We are persuaded that, based on Wegner, an ordinarily skilled artisan would have known to remove the Edison base of Chou’s fixture regardless of the type of reflector and housing used in Wegner’s fixture. See Ex. 1002 ¶ 53. Regarding motivation, Petitioner posits a market-based rationale, namely, that an ordinarily skilled artisan would have been motivated to make a version of Chou’s luminaire to fit nominally sized junction boxes to serve the new construction market. Pet. 25 (citing Ex. 1002 ¶ 54). Dr. Coleman testifies that the Edison base would have been removed to make Chou’s luminaire work in a junction box. Ex. 1002 ¶ 53.

    “construction against the prior art than it does to construction of the term itself. Patent Owner’s proposed construction, like Petitioner’s, does not, on its face, exclude RF protocol conversion. In this respect, we agree with Petitioner that Patent Owner is improperly attempting to read in additional limitations that go beyond claim 5’s broad recitation of a “transmitter . . . configured to encode the electrical signal.” See Paper 45, 3. As Petitioner further observes, the Specification of the ’661 patent refers interchangeably to data controller 324 (shown in Figures 3A–3E, not reproduced here) as “data formatter 324” (emphasis added), which “operates to form concise data packets.” Id.; Ex. 1001, col. 8, ll. 49–51. Petitioner’s proposed construction is thus consistent with the Specification. Patent Owner agrees that data controller 324 “encodes a physical condition into a function code,” but emphasizes that it does so “before getting converted by the RF transmitter.” Paper 44, 3. The distinction Patent Owner relies on to exclude RF protocol conversion from its proposed construction would improperly narrow the scope of the claim by implicitly adding a limitation that has no express basis in the claim. In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) (“Nevertheless, ‘reading a claim in the light of the specification,’ to thereby interpret limitations explicitly recited in the claim, is a quite different thing from ‘reading limitations of the specification into a claim,’ to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim.”).

    “Patent Owner does not advocate for a specific level of skill in its Response, but its expert, Kevin C. Almeroth, Ph.D., articulates a level of skill similar to Petitioner’s proposal. Ex. 2009 ¶ 75. Specifically, Dr. Almeroth opines that a person of ordinary skill “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent and experience with, or exposure to, computer networks and routing.” Id. In addition, according to Dr. Almeroth, a person of ordinary skill “would also have approximately two years of professional experience with computer networking, routing, and wireless networks. Id. And “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Given the similarity of articulations by the respective experts, and because our Decision does not depend on nuanced distinctions of the level of skill in the art, we adopt Dr. Almeroth’s more detailed articulation, but include electrical engineering as an additional alternative educational background, as indicated by Mr. Kinney.” slip op. at 15

    “We thus agree with Patent Owner that the rationale articulated by Petitioner is conclusory, and insufficiently supported. PO Resp. 30–31. On the record before us, it is more reasonable to construe “the transceiver identification information” as referring to something other than the identification information for the at least one wireless transmitter. For example, Patent Owner contends that “[o]ne skilled in the art, reading the plain text of claims 5 and 8, would easily recognize that the ‘transceiver’ referred to in claim 8 is the transmitter in claim 5 that is configured to both send and receive signals.” Id. at 33. Patent Owner provides support for this reading both by identifying disclosure in the Specification of the ’661 patent consistent with its position, and through testimony by its expert, Dr. Almeroth. Id. at 33–36 (citing Ex. 1001, Figs. 2, 3C, 3D, col. 6, ll. 3–8, col. 9, ll. 53–56, col. 10, ll. 32–34; Ex. 2009 ¶¶ 125–132). For example, Dr. Almeroth testifies that Mason’s AMR server “at most would need only some meter identification number and a meter reading.” Ex. 2009 ¶ 134. We credit this testimony, as well as Dr. Almeroth’s assertion that “[t]ransceiver identification information is extraneous for the needs of the AMR server in Cunningham and Mason.” Id. Ultimately, we need not resolve the construction issues, and the issue of whether claim 8 is indefinite is not before us. 35 U.S.C. § 311(b) (limiting inter partes review to “a ground that could be raised under section 102 or 103”). It is sufficient for us to determine whether Petitioner has put forth sufficient evidence to meet its burden of establishing that claim 8 would have been obvious over the combination of Mason, Shuey, and Cunningham.

    “c. “one or more additional wireless transmitters” Third, Petitioner combines the teachings of Shuey with those of Mason in addressing claim 5’s recitation of “one or more additional wireless transmitters.” Id. at 62–63. The claim requires that each such additional wireless transmitter is “electrically interfaced with a sensor and configured to receive the RF signal and retransmit the RF signal,” i.e., to act as a repeater. Ex. 1001, col. 19, ll. 22–24. As discussed above, Mason discloses that meter 12D is considered “inaccessible” with respect to node 18, and that another meter within the network may act as a repeater so that the inaccessible meter may still be contacted. Id. at col. 6, ll. 27–35. Petitioner cites Shuey for details regarding the information included in retransmission by meters acting as repeaters, and provides sufficient reason to effect the combination in light of Mason’s explicit reference to Shuey: “A POSITA would have been motivated to incorporate into Mason’s system Shuey’s teaching of a repeater that retransmits all of the claimed information, because Mason explicitly notes that Shuey’s system is a system for which Mason’s invention is particularly suited.” Pet. 58–59 (citing Ex. 1007, col. 6, ll. 35–38; Ex. 1002 ¶¶ 110–112).

    “We are not persuaded by this reasoning. As Petitioner observes, the embodiments of the ’624 patent identified by Patent Owner are characterized as “examples,” and a person of ordinary skill “would understand that the example scenarios of the specification are not necessarily limiting on the claims.” Reply 3 (citing Ding Supp. Decl. ¶ 6). In addition, Petitioner notes that claim language in related patents owned by Patent Owner explicitly refers to participants, evidencing Patent Owner’s understanding “how to expressly create participant-specific voting requirements in claims.” Id. at 3. At the oral hearing, Patent Owner suggested that explicit reference to participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications apparatus,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise. Ex. 1014, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction.

    “Patent Owner responds that “the Gerten device is not capable of and expressly teaches away from performing this functionality.” PO Resp. 15 (citing Melendez Decl. ¶ 33). Patent Owner contends that “Gerten’s disclosure is directed toward eliminating channels for use in an entire piconet as opposed to eliminating channels for use by certain participants within a piconet.” Id. at 16 (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 60, 64. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 45. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.
