T 1045/14 (Broadcast channel identification/CORE WIRELESS Licensing) 08-06-2018

1. Main request - claim 1 - inventive step

1.1 D1 is taken as representing the closest prior art, since it also relates to an apparatus ("digital radio receiver") for receiving audio broadcasts, the receiver being adapted to reproduce a channel identifier in the form of sound clips in response to user operations (see the summary). The apparatus of D1 includes "user operable means" for selecting a specific program (column 1, lines 46 to 48) or, in other words, a specific broadcast channel ("... from which the user can select a desired program such as Radio 4 using the control panel ...", column 3, lines 37 to 39). The control panel provides user inputs to a central processing unit, i.e. a control unit (column 2, lines 36 to 40).

Since the receiver is digital and comprises a central processing unit, it implicitly comprises a memory coupled to the central processing unit for storing instructions and the settings required for the operation of the digital receiver.

1.1.1 The appellant argued that D1 did not disclose any selection items because it did not further describe the user interface or the control panel and gave no details of the channel selection procedure.

The board understands the term "selection item" in claim 1 as being a key or a menu item, in line with the description of the application at hand (see page 9, lines 14 to 26: "In alternate embodiments, a user may access the memory locations by scrolling through and activating/selecting menu items of the mobile device 100. The menu items may be any suitable items such as, for example, numbers, letters or symbols. These selection items (e.g. the keys or menu items) associated with the memory locations for identifying an internet, radio or television channel may allow a user to directly access an internet, radio or television channel without scanning or scrolling through, for example, each and every internet, radio or television broadcast channel/frequency available to be received by the mobile device 100."). Further, the board notes that D1 discloses a menu system used for receiving the user inputs (column 2, lines 47 to 51). In the board's view, a menu system implicitly comprises menu items or, in other words, selection items to be activated by a user to select the desired function.

1.1.2 The appellant further argued that D1 did not disclose the feature of claim 1 of associating a channel identifier with a selection item and the feature whereby the channel identifier was played when a particular selection item was activated by the user, since a selection item could not be derived directly and unambiguously from D1.

With respect to whether D1 discloses selection items, the board refers to the previous point. Further, upon operation of the user-operable means of D1, the control unit causes the desired function to be selected and an appropriate audio clip to be played (column 2, line 56, to column 3, line 4). The desired function may be the selection of a specific broadcast channel, in which case the audio clip can be considered as a channel identifier (column 3, lines 9 to 13). Since activating a specific selection item results both in the desired broadcast channel being played and in the audio clip linked to this broadcast channel being reproduced, it follows that there is an association between the selection item, the selected broadcast channel and the sound clip corresponding to this broadcast channel. Hence, the selection item is also associated with the audio clip.

1.1.3 D1 further discloses that the audio clips can be pre-recorded and loaded into the receiver during manufacture (column 3, lines 5 and 6). D1 does not disclose limitations with respect to the functions with which these audio clips are associated. The audio clips can be updated by a broadcaster (column 3, lines 6 to 9).

1.2 D1 thus discloses, using the language of claim 1, an apparatus ("digital radio receiver", summary, column 2, lines 26 to 28) comprising:

a memory for associating selection items (menu items of the "menu system") with radio broadcast channels and for associating at least one selection item with a channel identifier ("audio clip"); and

a control unit configured to cause an associated channel identifier to play when a corresponding one of the selection items is activated by the user.

1.3 The subject-matter of claim 1 thus differs from the receiver disclosed in D1 in that according to claim 1:

(a) the selection items are selection items of at least one set of channel presets; and

(b) the channel identifier which is associated with a selection item is user-defined, is selectable by the user independently of the selection items and is user-configurable.

1.4 The arrangement of the selection items in a set of channel presets according to feature (a) gives a user direct access to a specific selection item and, hence, a radio channel.

Since in D1 the menu system includes menu items which can be activated by a user in order to select a desired function, e.g. a desired radio channel, in the board's view, it would be obvious, if not implicit, to the skilled reader that the menu items represent radio channels the user may select from. These menu items would thus constitute a set of radio channel presets the user may select from. This interpretation of the term "channel presets" is also in line with the description, stating that: "These keys and menu items associated with the radio, television or internet broadcasts are referred to herein as channel presets." (page 9, lines 26 to 28). Feature (a) thus does not contribute to an inventive step.

1.5 A technical effect of feature (b) is that the user is given the possibility to associate one of the audio clips loaded into the receiver during manufacture with a specific broadcast channel.

With respect to this feature (b), the underlying problem may be seen as how to implement the apparatus disclosed in D1 such that an audio clip loaded into the receiver during manufacture can be associated with a broadcast channel.

1.6 The board notes that at the time of manufacture of the receiver of D1 it cannot be fully known which broadcast channels will eventually be receivable at the time and place where the receiver will be used. Clearly, therefore, the need to associate new broadcast channels with audio clips may arise after manufacture.

The board further notes that D1 already discloses user-defined associations between an audio clip and a broadcast channel, namely in respect of the audio clips provided by a broadcaster (paragraph [0015]: "In one possible refinement of the invention, the broadcaster could send a collection of audio clips including more than one for each function, and the receiver could be equipped to enable the user to choose which is to be used, for example by cycling through the options. Thus the user could choose between alternative voices and/or alternative languages."). The skilled person, starting out from D1 and faced with the above-mentioned problem, would therefore in a similar way give the user the possibility also to create an association between an audio clip loaded into the receiver during manufacture and a broadcast channel, resulting in a user-defined channel identifier. Since the audio clips preloaded into the receiver during manufacture are not limited with respect to the functions they can be associated with, the channel identifier would therefore be selectable by the user independently of the selection items. The board further notes that the term "user-configurable" in feature (b), according to paragraph [0032] of the description of the present application, includes the meaning that the channel identifier may be turned on and off and that this property is inherently included when a user has the possibility of associating a channel identifier with a broadcast channel or of changing this association.

1.7 The appellant argued that D1 did not disclose channel presets and that without such channel presets it would be impossible to associate a selection item with a channel identifier or audio clip, since a user, without channel presets, could only scroll through the entire range of available broadcast channels.

The board is not convinced by this argument. D1 discloses that a specific broadcast channel may be selected ("Capital Radio", column 3, lines 9 to 13). Even if this were done by scrolling through a list of channels and finally selecting one, it is implicit that at least at the time of the selection the broadcast channel to be selected is associated with the corresponding selection item. Since selecting this specific selection item not only causes the channel "Capital Radio" to be selected but also the appropriate audio clip to be played, there is an association between that specific selection item and that audio clip.

The appellant further argued that the subject-matter of claim 1 allowed the channel identifier to be played upon selection of an associated broadcast channel, independently of the signal strength of the selected broadcast channel. The board understands this argument to concern the embodiment in D1 in which the audio clips are reproduced in response to a broadcast signal (summary). D1, however, also discloses a further embodiment in which the audio clip is reproduced in response to user operations (summary).

1.8 The board therefore concludes that the subject-matter of claim 1 of the main request does not involve an inventive step (Articles 52(1) and 56 EPC).

2. First auxiliary request - claim 1 - inventive step

2.1 The only limitation added to claim 1 of the first auxiliary request is that the control unit is coupled to the memory. This feature is, however, implicitly disclosed in D1 (see point 1.1 above). The above considerations in respect of claim 1 of the main request therefore apply mutatis mutandis.

2.2 The board therefore concludes that the subject-matter of claim 1 of the first auxiliary request does not involve an inventive step (Articles 52(1) and 56 EPC).

3. Second and third auxiliary requests - claim 1 - inventive step

3.1 Compared to claim 1 of the first auxiliary request, claim 1 of the second auxiliary request includes the additional wording "selection items in the form of keys and/or menu items". Selection items in the form of menu items are, however, implicitly disclosed in D1 (see point 1.1.1 above). The above considerations in respect of claim 1 of the first auxiliary request therefore apply mutatis mutandis.

3.2 Claim 1 of the third auxiliary request is identical to claim 1 of the second auxiliary request.

3.3 The board therefore concludes that the subject-matter of claim 1 of each of the second and third auxiliary requests does not involve an inventive step (Articles 52(1) and 56 EPC).

4. Fourth auxiliary request - claim 1 - inventive step

4.1 In the board's view, the wording "defining selection items to correspond with broadcast channels" has the same meaning as "associating selection items with broadcast channels" used in claim 1 of each of the higher-ranking requests. The same applies to the wording "for linking ... to" and "for associating ... with" used in claim 1 of each of the higher-ranking requests. Further, in the board's view, the term "user preset selection items" has the same meaning as "channel presets" used in claim 1 of each of the higher-ranking requests. The board notes that paragraph [00031], to which the appellant referred in respect of this amendment, does not give these terms any different meaning.

The amendments in claim 1 of the fourth auxiliary request therefore do not change the subject-matter of claim 1 of the second auxiliary request. The above considerations in respect of claim 1 of the second auxiliary request thus apply mutatis mutandis.

4.2 The board therefore concludes that the subject-matter of claim 1 of the fourth auxiliary request does not involve an inventive step (Articles 52(1) and 56 EPC).

5. Fifth auxiliary request - claim 1 - inventive step

5.1 Compared to claim 1 of the fourth auxiliary request, claim 1 of the fifth auxiliary request includes the additional feature "said user defined channel identifier not being defined, linked to a selection item, or caused to play by signals received from a broadcast station on said broadcast channel".

5.2 The board notes that in the embodiment of the receiver of D1, in which the audio clips are loaded into the receiver at the time of manufacture and reproduced in response to user operations, the channel identifier is not defined, linked to a selection item or caused to play by signals received from a broadcast station on said broadcast channel. The above considerations in respect of claim 1 of the fourth auxiliary request thus apply mutatis mutandis.

5.3 The board therefore concludes that the subject-matter of claim 1 of the fifth auxiliary request does not involve an inventive step (Articles 52(1) and 56 EPC).

6. Conclusion

As there is no allowable request, it follows that the appeal is to be dismissed.
