T 2496/17 (Accessing spreadsheet objects/PALANTIR TECHNOLOGIES) 06-05-2020

1. The appeal complies with the provisions referred to in Rule 101 EPC and is therefore admissible.

2. The invention

2.1 The application relates to spreadsheet applications. Paragraph [0003] of the background art section explains that inputting raw financial data into a spreadsheet and analysing such data is cumbersome and error prone because such data is large, includes many dependencies and may not fit well into a spreadsheet's row/column organisation. In addition, the corresponding expressions typically reference a large number of cells, which makes it difficult to locate the source of an error.

2.2 The invention essentially proposes a spreadsheet application that allows users to associate a "data object" with a first cell and to reference that data object together with a parameter of the data object in an expression contained in a second cell. When the expression in the second cell is evaluated, a value is returned for "the selected parameter in relation to the data object" by querying a database.

To input the expression, the user first enters a reference to the first cell. In response, the spreadsheet application displays a list of "suggested parameters associated with the data object". The user then selects one of the suggested parameters. The Board notes that such a mechanism of facilitating user input is known in the art as (context-dependent) "auto­completion" (see documents D5 and D1 to D3).

2.3 In the embodiment described in paragraphs [0078] and [0079] of the description with reference to Figure 3, the first cell "A1" contains the data object "GOOG". The user enters an expression in the second cell "B2" by inputting "A1" and selecting a parameter of the data object "GOOG" from a list of suggestions provided in the dialog box 310 by auto­complete logic 206.

3. Interpretation of claim 1

3.1 The method of claim 1 essentially corresponds to the invention as described in point 2.2 above.

First, a data object is associated with a first spreadsheet cell in a spreadsheet application running on a first computer. This data object is related to one or more parameters. A value of a parameter "in relation to the data object" can be determined by querying a database at a second computer.

Then, a "first input" forming part of an expression for a second cell is received. This input includes a reference to the first cell. In response to the first input, one or more object parameters are displayed as "suggested parameters" for selection by the user. The selected parameter is associated with the expression, i.e. the expression is auto­completed to include the parameter.

Finally, the autocompleted expression is evaluated to obtain the value to be displayed in the second cell. The evaluation process first "replaces" the first cell reference with the data object associated with the first cell. The resulting "modified expression" is then further evaluated by querying the database at the second computer to determine the value of the selected parameter of the data object.

3.2 In its statement of grounds of appeal, the appellant placed particular emphasis on the claim's "replacement operation". However, in this respect the Board agrees with the Examining Division that paragraph [0076] of the description, on which this feature is based, merely describes the straightforward evaluation of an expression such as "A1.close": first "A1" is evaluated (or "resolved"), which results in "GOOG", then the intermediate "modified" expression "GOOG.close" is evaluated. This is no different from evaluating an expression such as "F1+G3" by first replacing "F1" and "G3" with the values stored in the cells F1 and G3 (for example, 6 and 9) and then evaluating the intermediate "modified" expression "6+9" to obtain 15. The application discloses neither that the intermediate "modified" expression is displayed to the user nor that it is stored in the spreadsheet.

4. Novelty over document D1

4.1 Document D1 relates to the autocompletion of formulas as they are input in spreadsheet cells (see abstract and paragraph [0001]). In its decision, the Examining Division argued that Figure 3 disclosed a spreadsheet in which a data object "", having parameters of a stock ticker symbol such as "CLOSE" and "52WKHIGH", was associated with cell "B1" in the "Stock Ticker" column (referred to in the decision as column "B"). It was clear from Figure 3 that the "Quantity Purchased", "Quantity Sold" and "Purchase Price" columns (referred to in the decision as columns "E", "F" and "H") referenced the "Stock Ticker" column.

4.2 The spreadsheet shown in Figure 3 is mentioned in paragraph [0012] of document D1 but not discussed in any detail. In particular, there is no mention in document D3 of the stock ticker symbols in the "Stock Ticker" column being associated with corresponding data objects or of the cells in the "Quantity Purchased", "Quantity Sold" and "Purchase Price" columns containing references to cells in the "Stock Ticker" columns. The skilled person reading document D1 would have had no reason to assume that the cells of the "Stock Ticker" column contain anything other than simple strings, with no underlying logic. Nor would he conclude that the cells of the other columns refer to a parameter of a stock ticker data object. At best, he would infer that the cells in one of the "Quantity Purchased", "Quantity Sold" and "Current Holdings" columns contain an expression referencing the cells in the other two columns (given that the value in "Current Holdings" is the value in "Quantity Purchased" minus the value in "Quantity Sold").

4.3 Hence, the Examining Division's analysis of document D1 is not based on an objective evaluation of the document's technical disclosure, but is speculative and apparently tainted by hindsight knowledge of the claimed invention. Therefore, the decision's reasoning is not convincing.

4.4 Since document D1 does not disclose associating a cell of a spreadsheet with a data object and evaluating an expression referencing the cell by querying a database to obtain the value of a parameter of the data object, the subject-matter of claim 1 is new over document D1 (Article 54(1) and (2) EPC).

5. Novelty over documents D2 and D3

5.1 Document D2 relates to an autocompletion tool for assisting a computer programmer (paragraphs [0001] and [0019] to [0021]; Figures 2 to 9). Document D3 relates to an autocompletion tool for entering data into a spreadsheet (abstract). Neither document discloses associating a cell of a spreadsheet with a data object and evaluating an expression referencing the cell by querying a database to obtain the value of a parameter of the data object.

5.2 The subject-matter of claim 1 is therefore new over documents D2 and D3 (Article 54(1) and (2) EPC).

6. Remittal to the Examining Division

6.1 In view of the above, the reasons for refusing the application are clearly incorrect.

6.2 However, the question whether the claimed invention involves an inventive step over documents D1 to D3 has yet to be investigated.

6.3 Moreover, since the Examining Division has misinterpreted document D1 as disclosing associating cells of a spreadsheet with data objects and evaluating expressions referencing such cells by querying a database, and since the Search Division may have done the same, there is a distinct possibility that the search into the state of the art was stopped too early (see Guidelines for Examination, November 2019, B-IV, 2.6).

Indeed, document D4, which was cited by the USPTO in the proceedings for the related patent application US 2013/0036346 A1, at least prima facie appears to disclose associating a cell of a spreadsheet with a data object and evaluating expressions referencing the cell by querying an external data source (see abstract; column 5, lines 47 to 53; column 6, line 55, to column 7, line 17; column 7, line 61, to column 8, line 11) and may well represent a better starting point for assessing inventive step than any of the documents cited in the European search report.

6.4 Since inventive step over documents D1 to D4 has not yet been assessed, and since the search into the state of the art may not yet be complete, special reasons within the meaning of Articles 11 and 12(2) RPBA 2020 present themselves (see for example decisions T 1966/16 of 20 January 2020, reasons 2.2; T 731/17 of 15 January 2020, reasons 7.2 and 7.3). It is therefore appropriate for the Board, in exercising its discretion under Article 111(1) EPC, to remit the case to the Examining Division for further prosecution on the basis of the main request.
