The invention attempts to avoid this inefficient handling of schema updates, in particular where database backup occurs over the air (by radio communication), as performing a backup of all records of a database can be time-consuming and costly to a user.2.3 The invention solves this problem by comparing at a portable device a new version of a database schema to its prior version, by generating an update command, based on the comparison, to update the database at the portable device to conform to the new schema, by updating the database at the portable device using the generated update command, and transmitting the update command over the air from the portable device to a server storing a backup database of the database at the portable device to enable the server to update the backup database in the same manner using the transferred update command.Different schema updates (add/modify/delete field) are specified in more detail. Amendments - Article 123(2) EPC3.1 With the statement of grounds of appeal the appellant submitted that claim 1 of the main request had been amended compared to claim 1 of the main request considered in the contested decision to specify that:(a) the updated database schema defined an updated structure of the data records in the database;(b) the database was associated with mail store content;(c) the update command was generated prior to updating of the data records in the database;(d) the data records of the database were updated according to the update command;(e) data stored in a second field in each of the data records was deleted if said database schema changes comprised a modification of said second field of the data records;(f) the update command was transmitted from said portable electronic device to a server by way of a radio communication channel;(g) the backup database was updated by performing the steps "deleting a first field", "deleting data" and "adding a new field" on backup data records of the backup database according to the update command;(h) the backup data records were updated such that each of the backup data records of the backup database conformed to the updated structure as defined by the updated database structure.

Hence, any change in a database schema, including a simple modification of a single field in the schema, results in the invalidation of the entire backup database.

Hence, the generating step was not disclosed by D5.

With respect to feature F4, the appellant argued that the log messages used in D5 were unspecific, whereas the update command was "specific to the corresponding backup database" and that the broadcasting of log messages was different from the transmission of the update command.

The applicant (appellant), whose name at the time was Research In Motion Limited, appealed against the decision of the Examining Division refusing European patent application No. In the written proceedings the Examining Division also cited the following prior-art documents: D1: US2005/120123 published on 2 June 2005, D2: US2005/071344 published on 31 March 2005, D3: US2004/224675 published on 11 November 2004, D4: Marco Mesiti et al.: "X-Evolution: A System for XML Schema Evolution and Document Adaptation", 10th International Conference on Extending Database Technology, Munich, Germany, 26-31 March, 2006, LNCS 3896, published on 31 March 2006. With the statement of grounds of appeal, the appellant submitted a new main request and new first and second auxiliary requests.

In the course of the appeal proceedings, the appellant changed its name to Black Berry Limited. The Examining Division decided that the subject-matter of the claims of the main request and of the first and second auxiliary requests lacked inventive step over the prior art disclosed in the following document: D5: Ronström, Mikael: "Design and Modelling of a Parallel Data Server for Telecom Applications", Ericsson Utveckling AB 1997.

The corresponding independent claims 14 and 15 had been amended accordingly.

With respect to the basis for these amendments, the appellant referred for amendment (a) to paragraph [0023] of the description, for amendment (b) to paragraph [0009] of the description, for amendment (c) to Figure 4 and the related description, for amendment (d) to paragraph [0025] of the description, for amendment (e) to former claim 2, for amendment (f) to paragraph [0015] of the description, for amendment (g) to claim 7 and paragraph [0026] of the description, and for amendment (h) to paragraph [0009] in combination with paragraph [0005] of the description.It requested that the decision be set aside and that a patent be granted on the basis of one of the main and the first and second auxiliary requests. In a communication pursuant to Rule 100(2) EPC, the Board essentially agreed with the appellant's assessment of document D5 and found that the reasons given by the Examining Division did not justify the refusal of the application.However, as the Board was aware of a further prior-art document which might prejudice the patentability of the claimed subject-matter, the following courses of action were proposed:(a) The Board would decide to set aside the decision under appeal and remit the case to the department of first instance for further prosecution.Claim 11 of the main request reads as follows:"A computer-readable medium having computer-readable code embodied therein for updating and backing up a database, comprising data records, to accord with an updated database schema, said computer-readable code for causing a computing device or system to perform the method of any one of claims l to 10."Claim 12 of the main request reads as follows:"A portable electronic device (22) comprising:an input for receiving an updated database schema associated with a database (40, 42, 44);a memory for storing data records in said database;a processor (46) for executing computer-readable code embodied in a computer readable medium of the portable electronic device (22), said computer-readable code for causing the portable electronic device to perform the method of any one of claims 1 to 6."Claim 13 of the main request is dependent on claim 12.Claim 14 of the main request reads as follows:"A method carried out at a server (30) for updating a backup database (34, 36, 38) comprising backup data records stored on the server, to accord with an updated database schema of a database (40, 42, 44) operated by a portable electronic device (22), wherein the database (40, 42, 44) operated by the portable electronic device (22) is associated with mail store content, the method comprising:receiving an update command (114) from the portable electronic device (22) by way of a radio communication channel, said update command for enabling updating a database schema for the backup database (34, 36, 38);wherein the update command comprises database schema changes of the updated database schema with respect to a previous database schema of the database (40, 42, 44) operated by the portable electronic device (22);wherein the previous and updated database schema define a structure of the data records in the database (40, 42, 44) operated by the portable electronic device (22); andupdating (118) the backup data records according to the update command so that each of the backup data records of the backup database (34, 36, 38) conforms to the updated structure as defined by the updated database schema, by:deleting a first field from each of the backup data records, if said database schema changes comprise a deletion of said first field of the data records,deleting data stored in a second field in each of the backup data records, if said database schema changes comprise a modification of said second field of the data records; andadding a new field in each of the backup data records, if said database schema changes comprise an addition of said new field of the data records."Claim 15 of the main request reads as follows:"A server (30) for updating a backup database comprising backup data records, to accord with an updated database schema of a database (40, 42, 44) operated by a portable electronic device (22), wherein the database (40, 42, 44) operated by the portable electronic device (22) is associated with mail store content, the server comprising:means for receiving an update command (114) from the portable electronic device by way of a radio communication channel, said update command for enabling updating a database schema for the backup database (34, 36, 38), the backup database stored at the server;wherein the update command comprises database schema changes of the updated database schema with respect to a previous database schema of the database (40, 42, 44) operated by the portable electronic device (22);wherein the previous and updated database schema define a structure of the data records in the database (40, 42, 44) operated by the portable electronic device (22); andmeans for updating (118) the backup data records according to the update command so that each of the backup data records of the backup database (34, 36, 38) conforms to the updated structure as defined by the updated database schema, by:deleting a first field from each of the backup data records if said database schema changes comprise a deletion of said first field of the data records,deleting data stored in a second field in each of the backup data records, if said database schema changes comprise a modification of said second field of the data records; andadding a new field in each of the backup data records, if said database schema changes comprise an addition of said new field of the data records."The wording of the claims of the auxiliary requests is not relevant to the present decision. The appellant's arguments relevant to the Board's decision are discussed in detail below. The appeal complies with the provisions referred to in Rule 101 EPC and is therefore admissible. The application relates to database schema updates for synchronised databases, for example a database and its synchronised backup database.The Board notes that paragraph [0025] of the description is a suitable basis for amendment (e) and that original claims 5, 6, 10 and 11 are a relevant basis for amendment (g).
