`
`The chairman opened the oral pmoeedinge at 9:04 and asked the applicant (AP) if he
`maintained the request as filed with letter of 28/05/04.
`AP confirmed maintenance of these requests.
`
`A) Art 1 23(2)
`
`The compliance of claim 1 of the main request with the requirements or Art. 123(2) was
`then discussed.
`
`_,
`
`in particular. the chainrran pointed out that an additional area for orders . that could be
`differentiated from the first and second areas or oolumns corresponding to the bid and
`ask prices, was defined in the last paragraph of claim 1 and asked AP to give the basis
`in the originlly tiled application for that feature.
`
`Aooording to AP, a basis for that generalization can be seen in last paragraph of page
`16 and first paragraph of page 17. Fora person skilled in the art (PSIA) it is evident that
`the price level is important and therefore thatthe positioning of the click has not to be
`limited for the bid or ask columns.
`
`The chairman maintained that all embodiments disclosed in the patent showed the click
`
`on the bid or ask columns and that the examining division (ED) did not see any basis
`
`for accepting the generalization.
`
`.
`
`-/’
`
`in AP'a vlw. it is not stated in the application that the positioning of the click is an
`essential fture and therefore the generaiticn is for the PSIA evident and allowable.
`
`The Chairman asked for the basis of the expression "price axis" which is now used in
`claim 1.
`
`According to AP, column 1005 of figure 3. is an axis because the column is static.
`
`. Chairman replied that the prices in the column are static but not the column itself and
`moreover that it is a column and not an axis and that the generalization is a priori not
`alowabie.
`
`AP then requested to show the presentation they had prepared so that the ED would be
`able to acknowledge what a PSIA would have understood at the date of filing of the
`
`EPOF¢rn2ll 01.91D8X

`
`present application and , therefore, what could be accepted as generalization.
`
`The chairman repried that the analysis of 123(2) has to be based on the documents as
`originally filed.
`
`AP was asked where the difference between a column and an axis is to be seen. He
`
`replied that an axis can be not only vertical. like a column, but also horizontal. In fact an
`axis can present any form. as for example an 8 form.
`
`The chairman presented a last point concerning 123(2). New claim 1 is apparently
`based on original claim 35 without the feature of last paragraph. According to the ED
`said feature is essential and therefore cannot be deleted.
`
`AP replied that the basis train new claim 1 is claim 1 as originally filed evn it the
`category of these two claims is different. The features of last paragraph of claim 35 are
`not essential to the subiectwnatter of present claim 1.
`
`The proceedings were paused at 9:50 and resumed at 10:17.
`
`The applicant filed a new first auxiliaru request taking into account the discussion of
`123(2).
`
`AP gave the following basis for amendments
`
`'-»
`
`Feature A), see fig 3
`Feature 3). description page 16. line 13 and page 17. line 1 and 26.
`"Range of prices". fig 3 and page 13. line 14.
`
`The Proceedings were paused at ttxso to decide on Art- 123(2) for the main request
`and the newly filed first auxiliary request
`
`The proceedings were resumed at 11:02
`
`The chairman announced the following

`
`requirements of Art.123(2) for the two following reasons
`
`a)
`
`b)
`
`there is no basis for the use of the term "price axis“ in the originally filed
`application.
`
`The definition of an "order entry region" comprising a plurality of areas which
`may be different from the first and second area is considered as being an
`
`unallowable generalization.
`
`Concemlng claim 1 of the first auxiliary request, it also does not fulfil the requirements
`
`_,
`
`of Art. 123(2) for the following reasons.
`a)
`the definition ofthe plurality of areas in the order entry region allows for an
`interpretation of these regions being completely separated from the level of
`the price in the price column (unallowabla generalization)
`
`b)
`
`it is not possible 0 find a basis of the term range of price in the originally filed
`
`application”
`
`The chairman also announced that a basis for allowable amendments can be seen on
`
`page 12, last paragraph and claim 29, last lines of second and third paragraph of the
`application as originally filed.
`
`The proceedings were paused at 11:16 In order to allow AP
`claims.

`Anmel¢0~Nr.:
`
`AP then showed a presentation disclosing the prior art as disclosed in fig 2 of the I
`application and the embodiment of the invention, a software product called Xtrader.
`AP tried to make clear with the presentation the following points:
`
`-
`-
`
`-
`
`-
`
`-
`
`ln trader applications, the issue of speed has become very important
`In the prior an a trader may send a wrong order. with a who price. since
`the prices column may change more rapidly than the human rection is able
`to follow. With the embodiment of the invention, it is not possible because
`the values in the price column are static.
`”'
`With the embodiment of the invention, a trader needs less efforts to
`
`recognize the direction ofthe changes.
`the software is a huge commercial success
`
`with the embodiment of the invention, more space is available on the screen.
`
`After the presentation, a pause was made from 12:55 to 13:00.
`
`Afler the break, the chairman announced:
`- that the ED considered that the features relating to the order entry region confer
`technical character to the subject-matter of claim 1 of all requests. The
`requirements of Art 52(2) and (3) are therefore fulfilled for all requests.
`
`- Document D1 has to be considered as representing the closest prior art.
`
`v
`
`A lunch break took place from 13:05 to 14:00
`
`0) Art. 58
`
`Atter the break, the chainnan reminded the participants that claim 1 of the main request
`was objectionable on Art. 123(2) and that. therefore. the Art. 58 discussion will be
`based on claim 1 of the that auxiliary request.
`
`The first member summarized the position of the ED concerning the teaching of D1.
`The only difference which could be seen between the subject-matter of claim 1 and the
`
`teaching of D1 lies on the use of “field of statics prices".
`
`AP argued that the teaching of D1 was in fact similar to the prior art disclosed In iig.2 of
`
`EPO Pum& 01.91125!

`
`the application.
`The new feature was the central Idea of the invention and solved two problems
`
`-3)
`
`-b)
`
`how to display the market information such that the perception of the trader
`on market changes and thus his reaction time can be improved
`the trader wil always be able to place an order at exactly the desired price,
`irrespective of the speed at which the bid and ask prices change in real time.
`Thus, potential errors are reduced in the system.
`
`AP also argued that. in the trader world. the changes may occur in millisecond time and
`that the embodiment of the invention increased both the speed and accuracy at the
`orders made by the trader.
`
`,,-
`
`Moreover, a technical prejudice was overcome by the embodiment of the invention
`because for a trader it was a prion counterintuitive to display bids and asks relative to a
`static field since it gave the impression that in this way the amount of information
`received reduced. The traders were very reluctant in using the software Xtrader but in
`fact this software is now a big commercial success.
`
`To that last point, the second member noted that in his view. It was not a technical but a
`psychological prejudice which was overcome.
`
`AP argued again that even ifthe solution looks simple, it is inventive because a priori a
`PSIA would never come to the idea of introducing a field of static prices in the teaching
`of D1.
`
`9
`
`The chairman then noted that problem a) cannot support an inventive step because the
`increase of speed was not in the processing of the date but in the brain of the user. due
`to a different presentation of information.
`
`AP replied that problem b) is also solved by the introduction of the field of static prices.
`
`The proceedings were paused at 14:55 to allow the E0 to make a decision on Art. 56
`for claim 1 of the first auxiliary request.
`
`The proceedings were resumed at 15:55.
`
`The chairman announced the following:

`
`subjedematter of claim 1 solves a technical problem which is to improve the operabillty
`of the system in terms of increasing the accuracy for placing orders. In fact, this
`problem is independent from the business aspects of the claims. It relates to the fact
`that the user is confronted with two correlated changing measures in a real-time
`environment and the need to perform an action (order placing) on one measure (prices)
`at a guaranteed level. The solution is to use metadata to create a field of static values
`(prices). The other measures (bids and asks) are moved relative to the static field. This
`assures both speed and accuracy.
`Starting from the teaching of 01. the ED considers that this solution is new and
`inventive."
`
`The chairman then asked AP which were the current request on file.
`
`AP then presented a new main request based on the last claim 1 filed during oral
`proceedings. All other requests were withdrawn.
`
`The proceedings were paused at 16:10 in order to allow AP to prepare a complete set
`of specification.
`
`The proceedings were resumed at 16:50.
`
`AP tiled the following documents as basic for the only remaining request,
`
`v
`
`Pages 1. 4.5.8.920 as filed during proceedings
`Pages 2.3.6.7.1o-12.14-16.13.19 as originally filed

`
`Claims 1-55 filed during oral proceedings
`
`Figures as originally filed.
`
`During the following discussion and because of clarity problems. AP asked the ED to
`make 319 f0|l0W5l'l9 amendments with the communication according to rule 51(4).
`
`Replace claim 30 to claim 29 in page 43.
`Change the dependenw of claim 16 to make it dependent only on claim 1
