Summary of Facts and Submissions

I. European patent application number 01307626.0 claims priority from a Japanese patent application filed on 8 September 2000 for an information processing apparatus and method for providing content data to a terminal device.

II. The examining division refused the application pursued by the applicant on the basis of a main set of claims and a further limited auxiliary set of claims. According to the reasons for the decision given in writing and posted on 24 July 2007, neither the main set nor the auxiliary set of claims included subject matter inventive over prior art document D1 (WO 00/02389 A1 published in January 2000). The claimed invention, as argued in the decision, was distinguished from the prior art by "analysis means (76) for analysing a preference of a target user on the basis of the input information of a similar user" (claim 1 of the main request) and "the added feature of 'value added content'" (claim 1 of the auxiliary request). The invention was to be considered as an obvious computer implementation of non-technical business rules. Profiling data of similar users for determining preferences and giving recommendations on the basis of such information did not solve any technical problem. Speeding up the process of sending data to users, an advantage promoted by the applicant, was at best a side-effect of the implementation of the business rules.

III. The appellant (applicant) lodged an appeal against the decision of the examining division on 10 September 2007, paid the appeal fee on 12 September 2007 and filed the grounds of appeal including a new set of claims on 23 November 2007. In preparation of oral proceedings summoned by the Board, the appellant filed by letter dated 5 February 2014 two sets of claims as main request and 1st auxiliary request, respectively.

IV. In the oral proceedings held on 7 March 2014, the appellant withdrew his former main request and declared his former first auxiliary request, filed with letter dated 5 February 2014 to be his main and sole request. The appellant then requested that the decision under appeal be set aside and that a patent be granted on the basis of this new main request.

V. Claim 1 reads as follows:

"An information processing apparatus for providing content data to a terminal device, said information processing apparatus comprising:

content data storage means (71) for storing a plurality of pieces of content data;

communication means (73) for transmitting the content data stored in said content data storage means to a plurality of terminal devices (1) and for receiving input information of each user for the transmitted content data; and

input information storage means (75) for storing said input information received by said communication means for each user;

the apparatus being characterised by:

analysis means (76) for analysing a preference of a target user on the basis of the input information of a similar user, which resembles the input information of said target user stored in said input information storage means; and

processing means (72) for processing content data itself to be transmitted to said terminal device into value-added content for said target user according to the analysis results by said analysis means, wherein said content data storage means (101) stores a plurality of pieces of image data, and said communication means (103) receives positional information within said image data indicated by each of said users, said positional information indicating the centre of an area of said image data comprising features which are of interest to each of said users, and said analysis means (106) comprises extraction means for extracting said positional information of said similar user, which shows that an image area comprising features resembling the features comprised within an image area indicated by said positional information of the target user, stored in said input information storage means (105), is indicated, and said processing means (102) improves the image quality of a part of the image data specified on the basis of said positional information of said similar user, extracted by said extraction means (106), more than the image quality of the other parts of the image data."

VI. According to the appellant, the subject matter of claim 1 involved an inventive step over the prior art. The claimed invention provided an innovative way of choosing the parts of an image which were likely to be of most interest to a (target) user and for which the quality should be improved. These parts of the image were specified on the basis of the positional information of a similar user. The positional information of the similar user showed an image area comprising features resembling the features comprised within an image area indicated by the positional information of the target user. The positional information and features of interest were determined by the analysis means that analysed the click data from the target user as well as the click data from a similar user, i.e. from a user having the same preferences. Improving only specific parts of the image had the technical effect and advantage of allowing the amount of image data to be transmitted to be reduced whilst, at the same time, ensuring that features of the image data which were likely to be of interest to the target user were maintained in high-quality. This went above and beyond the common general technical knowledge related to image quality and data reduction and the teachings provided by the cited prior art. Document D1, cited as the closest prior art, was merely related to the transmission of individually targeted advertisements; it did not provide any form of image processing affecting the image quality, let alone the specific image quality processing arrangement of the present invention.
