`
`Claims 1, 3-5, 7, 8, 11, 12, 14-19,21-27,32-42,75-82,85-90,93-113, 118, and 119 are
`
`rejected under 35 U.S.C. 102(e) as b~ing anticipated by Dicker '353.
`,-
`Regarding cll;lim 1, Dicker '353 discloses a method for selecting communications
`
`channels for a communications system, the method comprising the computer-implemented steps
`
`of:
`
`selecting, based upon performances of a plurality of communications channels at a first
`
`time and channel selection criteria, a first set of two or more communic:ations channels from the
`
`plurality ofcommunication~ channels [see Abstract; also see col. 3, lines 23-45, wherein "To
`
`
`
`Application/Control Number: 95/000,648
`Art Unit: 3992
`
`Page4
`
`'
`improve the quality over each individual communication link 14a-17a between base station 12
`
`'
`and each of the plurality of mobile units 14-17, base station 12 has logic operable to evaluate
`
`parameters relating to the quality of individual communication links 14a-17a. Such parameters
`:
`
`'
`
`may include .those that indicate that signal bll:rsts or may include those th~t indicate that signal
`
`bursts or parts of signal bursts are lost or corrupted over the communication link. Other
`
`parameters are known to those skilled in the art."];
`
`, selecting, based upon performance of the plurality of communications channels at a
`
`second time that is later than the first time and the channel selection criteria, a second set of two
`
`or more communications channels from the plurality of communicatipns channels [see col. 4,
`
`lines 61-67, wherein "Because mobile unit communication system 10 optimizes the quality for
`
`each communication links 14a-17a, base stati?n 12 communicates with each mobile unit utilizing
`
`the frequencies that have the best quality available at the time for each communication link.
`
`Thus, base station 12 may .communicate with each mobile unit 14-17 utilizing a different
`.
`r
`
`frequency."; also see col. 7, lines 41-51, wherein "For example, in a direct sequence spread
`
`/
`
`spectrum system, base station 12 will need to notifY the mobile unit that it will be utilizing a n_ew
`
`carrier frequency for the communication link. In the emb~diment, base statio~ 12 may notify the
`
`mobile unit that it will change carrier frequenCies after~ number of (e.g. four) frames .... Base
`
`station 12 th,en uses a.frequency that utilizes the transmission attributes to communicate with the
`
`mobile unit when the mobile unit is ready in step 75."];
`
`wherein the communications system is a frequency hopping communications system and
`
`I
`
`the plurality of communications channels correspond to a. set of frequencies to be used based on
`
`a hopping sequence according to a frequency hopping protocol [see col. 3, lines 46-54, wherein
`
`
`
`Application/Control Number: 95/000,648
`Art Unit: 3992
`
`Page 5
`
`"Base station 12 is operable to communicate with mobile units 14-17 using radio frequencies,
`
`... Two ex~ples of such technology include frequency hopping spread spectrum and direct ·
`,·
`
`sequence spread spectrum communications."; also see col. 4, lines 29-67]; and
`
`wherein at each hop In the hopping sequence, only one communications channel is used
`I
`for communications between a pair of participants [see col. 4, lines 43-6.7, wherein "During the
`
`-
`j
`- duration of a given frame 22, base station 12 and the mobile units 14-17 communicate using-the
`
`selected frequency for that frame 22. When the next frame 22 begins, base station 12 and mobile
`
`'units 14-17 communicate using a new selected frequency."].
`
`Regarding claim 3, Dicker '353 discloses the method discussed above in claim 1, and
`
`further teaches that the plurality of communications channels communicatively couple at least a
`
`plurality of~ireless devices [see Fig. 1, mobile units 14, 15, 16, and 17].
`
`Regarding claim 4, Dicker '353 discloses the method discussed above in claim 3, and
`
`further teaches that the plurality of wireless devices includes one or more mobile devices [see
`
`Fig. 1, mobile units 14, 15, 16, and 17].
`
`Regarding claim 5, Dicker '353 discloses the method discussed above in claim 1, and
`
`further teaches of the steps of:
`
`generating first channel identification data that identifies the first set of two or more
`
`communications channels [see col. 4, lines 12-26; also see col. 7, lines 25-36, wherein "Such
`.
`.
`
`informing may be accomplished in a variety of ways known to those skilled in the art. For

`
`example, transmission attributes, such as a new set of blocked subsets representing the worst-
`
`quality channels may be communicated to the mobile unit as data or control parameters. They
`
`may also be encoded or passed to the mobile unit as tabular data."; also see Figs. 3 and 4];
`
`transmitting the first channel identi~cation data to one or more participants in the
`
`communications system over one communications channel ofthe plurality of communications
`
`cnarinels based on" the hopping s-equence according to the frequency hopping protocol [see col. 7'
`
`lines 28-36, wherein "Such inforriling may be accomplished in a variety of ways known to those

`
`transmitting the second channel. identification data to one or more participants in the
`
`communications system over one communications channel of the plurality of communications
`
`channels based on the hopping sequence according to the frequency hopping protocol [see Fig. 4,
`
`being steps 48-52 in the second loop through the process; also see col. 7, lines 28-36].

`
`Regarding claim 7, Dicker '353 discloses the method discussed above in claim 1, and
`
`further teaches that the channel selection criteria include a channel performance threshold [see
`
`col. 6, line 63-col. 7, line 24].
`,
`I
`
`Regarding claim 8, Dicker '353 discloses the method discussed above in claim 1, and
`
`. further teaches of the step~s of:
`
`generating first channel performance data that indicates the performance of the plurality
`
`of communications channels at the first time [see col. 6, line 53-63, wherein "For example, in
`
`step 64 the short-term and long-term error rates for each subset are compared and cleared at a
`
`short interval (e.g. every five seconds)."]; and
`
`generating second cha~nel performance data that indicates the performance of the
`
`plurality of communications channels at the second time [see col. 6, line 53-63, wherein "For
`
`example, in step 64 the short-term and long-term error rates for each subset are compared and
`

`
`Regarding claim 11, Dicker '353 discloses the method discussed above in claim 1, and
`
`further teaches of the steps of:
`
`determining the performance of the plurality of communications channels at the first time
`
`[see col. 6, line 53..:63, wherein "For example, in step 64 the short-term and long-term error rates
`
`for each subset are compared and cleared at a short interval (e.g. every five seconds)."]; and

`
`determining the performance of the plurality of communications channels at the second
`
`time [see col. 6, line 53-63, wherein "For example, in step 64 the short-term and long-term error
`

`
`see col. 7, lines 52-59, wherein "Steps 4-48 in Fig. 4 are performed for each mobile unit in
`
`system 10, as illustrated in step 50."].
`
`Regarding ciaim 12, Dicker '353 discloses the method discussed above in claim 1, and
`
`further teaches that the performance of the plurality of communications channels is based on
`
`channel performance data that is transmitted over one or more of the plurality of communications
`
`channels based on the hopping sequence according to the frequency hopping protocol [see col. 7,
`
`lines 24-45].
`
`Regarding claim 14, Dicker '353 discloses a method for selecting communications
`
`channels for a frequency hopping communications system, the method comprising the computer-
`
`implemented steps of:
`
`selecting, based upon perfonriance of a plurality of communications channels at a first
`
`time and channel selection criteria, a first set of two or more communications channels from the
`
`plurality of communications channels [see Abstract; also see col. 3, lines 23-45, wherein "To

`
`15-51, wherein "For example, in a direct sequence spread spectrum system, base station 12 will
`
`need to notify the mobile unit that it will be utilizing a new carrier frequency for the

`
`if the number of communications channels from the first set of two or more
`
`communications channels that satisfy the channel selection criteria at the second time is less than
`
`a specified number [see col. 5, lines 22-32, wherein "One such method to optimize the quality
`
