T 2151/08 22-06-2010

Reasons for the Decision

1. Admissibility

1.1 The Respondent argued that the statement of grounds of appeal does not meet the requirements of Article 108 and Rule 99 EPC inasmuch as the ground of insufficiency of disclosure is concerned, because the Appellant has merely repeated the arguments already presented before the first instance and failed to indicate why the impugned decision should be set aside.

1.2 However, the appeal was also based on the ground of lack of novelty in view of D2, D3, D4 and D5. The Board has no doubt, and there was also no objection from the Respondent that this ground of opposition was sufficiently substantiated in the statement setting out the grounds of appeal.

There is no support in the EPC for a notion of "partial admissibility" of an appeal. An appeal is either admissible or inadmissible (decision T 774/97, point 1 of the reasons).

Thus, if the requirement for an adequate substantiation is fulfilled at least for one ground of opposition the appeal as a whole is admissible, even if this requirement were not fulfilled for another ground of opposition raised in the statement of the grounds of appeal.

2. Objection under Article 100 (b) EPC

2.1 The Appellant submitted that the specification of the patent under appeal as well as claim 4 as granted refer to the possibility of having the clavicle removed before scraping off the inner fillets. This however would imply that the membrana has already been released and that therefore the method of claim 1 cannot be carried out anymore.

2.2 This view cannot be shared. The claimed method requires that prior to scraping off the inner fillet (second method step) the membrana has to be released "by inserting the separating elements (24) on opposite sides of the breastbone (8b), moving the separating elements (24) along the breastbone (8b) into the openings defined by the natural position of the clavicle (8c; 80) and the breastbone (8b)" (first method step). Removing the clavicle certainly damages the membrana, which however may still extend between the breastbone and the coracoids. Thus, inserting the separating elements in the claimed manner (so that the membrana is severed in a different way to obtain a different result) can still be effected.

Indeed, the claimed method can be carried out in the absence of the clavicle, since in this case the term clavicle merely defines the natural position of the clavicle, i.e. serves to define the location where the separating elements are to be inserted (see also patent specification, column 6, lines 49 to 51).

2.3 Accordingly, the invention is disclosed in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art (Article 100 b) EPC).

3. Amendments

Claim 1 has been amended by adding the following features [the membrana sternocoracoclavicularis] "is released by inserting the separating elements (24) on opposite sides of the breastbone (8b), moving the separating elements (24) along the breastbone (8b) into the openings…"

The Appellant made no objections under of Articles 84 and 123 EPC, nor did the Board see any reason to raise objections on its own motion.

4. Novelty

4.1 Novelty has been challenged with respect to D2, D3, D4 and D5.

4.2 D2

This document (column 5, lines 26 to 37; Figures 1, 3 to 8) describes a method and an apparatus for automatic removal of at least an inner fillet of a slaughtered poultry. This is performed in that "scrapers 12 are introduced into the meat directly behind the wing joints 63 and between the wish-bone 64 and the coracoid bones 62".

No reference is made to the membrana and there is no indication that the membrana is released.

The Appellant argued that introducing the scrapers into the meat directly behind the wing joints and between the wish-bone (clavicle) and the coracoids results in releasing the membrana.

However, D2 solely discloses that the scrapers are introduced into the meat and not all way through the meat. Since the membrana is located under the meat, it cannot be derived from D2 whether or not the separating elements move into the opening defined by the natural position of the clavicle and the breastbone such that the membrana is released; respectively whether or not the separating elements are adapted to be inserted into the openings defined by the natural position of the clavicle and the breastbone for the purpose of releasing the membrana.

Thus novelty of the subject-matter of claims 1 and 5 is given with respect to D2.

4.3 D3

This document (column 11, line 58 to column 12, line 30; Figures 21 to 26) discloses a method and an apparatus for automatic removal of at least an inner fillet of a slaughtered poultry. First knives 170 effect slight cuts to relieve connections between the clavicle, the carcass and the inner fillets (Figure 21). Next peeling fingers 42 enter the cuts initiated by the knives, adjacent the keel bone and peel away the connection between the inner fillet and the keel bone; whereas a second set of peeling fingers 44 extends the cut somewhat deeper (Figures 22, 23). Finally, wiping elements 46 engage the moving carcass to shave apart the remaining connection between the inner fillets and the carcass (Figures 24 to 26).

The Appellant contended that by extending downwardly closely adjacent the keel bone and by peeling away an upper portion of the connection between the inner fillets and the keel bone, the peeling fingers 42 must release the membrana.

This point of view cannot be shared. According to D3 the knives 170 act along the top of the carcass (column 11, line 61, 62; Figure 21). The peeling fingers 42 then enter the cuts initiated by the knives 170. There is no indication how with respect to the clavicle and the breastbone these fingers are positioned and how deep the peeling fingers 42 and 44 will penetrate into the meat.

Therefore it cannot be derived from D3 whether the peeling fingers are adapted to be inserted into the openings defined by the natural position of the clavicle and the breastbone, let alone that they are able to release the membrana.

Thus novelty of the subject-matter of claims 1 and 5 is given with respect to D3.

4.4 D4

This document (column 2, line 49 to column 3, line 6; Figures 1 to 4) describes a method and an apparatus for automatic removal of the inner fillets of a slaughtered poultry. Prior to removing the inner fillets, some parts of the carcass including the wings, the clavicle, the coracoids and thus the membrana have been severed (Figure 2). The separating elements for removing the inner fillets, knives 17 and plows 19 and 21 extend parallel to the keel bone and act between the carcass and the inner fillets to effect a separation. Since the part of the carcass comprising the opening defined by the natural position of the clavicle and the breastbone has been removed, the position in which the separating elements become active (i.e. act on the inner fillets and the carcass) is located beyond the position where the opening extended previously. It can therefore not be derived from D4 whether the separating elements would have been able to move into said opening, which is no longer present, and in such a manner that said movement would have resulted in releasing the membrana if it had been still there.

The Appellant argued that at least the features of the apparatus claim 5 are disclosed by D4. However, as stated above, there is no indication in D4 which could lead to the assumption that the separating elements disclosed therein would be adapted to be inserted into the openings defined by the natural position of the clavicle and the breastbone such that the membrana would be released.

Thus novelty of the subject-matter of claims 1 and 5 is given with respect to D4.

4.5 D5

This document (page 9, line 16 to page 10, line 32; Figures 1, 9 to 20) describes a method and an apparatus for automatic removal of the inner fillets of a slaughtered poultry. Prior to scraping off the inner fillets, the top 56 of the clavicle 57 is removed by a cutting die 22 which is moved into the neck opening of the carcass (Figures 9 and 10).

The Appellant contended that this operation releases the membrana. This is accepted by the Board, however the die used to release the membrana is a single tool which is introduced into the carcass through the neck opening.

Thus D5 does not disclose the features that the membrana "is released by inserting the separating elements on opposite sides of the breastbone, moving the separating elements along the breastbone into the openings" respectively that the separating elements "are adapted to be inserted, on opposite sides of the breastbone (8b), into the openings defined by the natural position of the clavicle (8c; 80) and the breastbone (8b) for the purpose of releasing the membrana sternocoracoclavicularis".

Thus novelty of the subject-matter of claims 1 and 5 is given with respect to D5.

5. Inventive step

5.1 The Appellant has submitted that the subject-matter of claims 1 and 5 lacks inventive step since the technical problem stated in paragraph [0008] of the patent specification, i.e. the provision "of a method and an apparatus be means of which inner fillets can be removed mechanically and automatically from the carcass of a bird, while the greatest possible amount of meat is obtained and damage to the meat is prevented as much as possible" has not been credibly solved.

5.2 However as submitted by the Respondent, from the anatomy of the poultry it can be seen that the membrana is situated behind the inner fillets and stretched like a tent between both coracoids, the two bones of the clavicle and the front side of the breast bone.

To remove the inner fillets and thereby preventing damage to the structure of the meat surface as much as possible, the membrana is released according to the invention by making a separation with separating elements in the opening defined by the natural position of the clavicle and the breastbone. By the movement shown in particular in Figure 4a of the patent specification, the separating elements separate the inner fillets from the breastbone along the path of the separating elements. When entering the opening defined by the natural position of the clavicle and the breastbone a separation is made so that the tent-shaped membrana is released from the breastbone. This separation is sufficient for intact removal of the inner fillets and thus without any loss or damage of meat.

Thus in the light of the described method, the above technical problem has been in essence plausibly solved by the claimed method or device.

5.3 Under these circumstances the patent proprietor is not required to provide further evidence, such as comparative examples to demonstrate that the technical problem stated in the patent specification has been solved. It is enough for it to appear plausible to the skilled person having regard to the described method that this technical problem can be solved by the claimed method or device.

5.4 Moreover, the Appellant argued that the subject-matter of claims 1 and 5 lacks an inventive step merely by stating that the technical problem stated in the patent specification has not been credibly solved, without reformulating the problem in question in a less ambitious way and without assessing the obviousness of the claimed solution in the light of the cited prior art as requested by Article 56 EPC. Article 56 EPC (first sentence) states that "an invention shall be considered as involving an inventive step if, having regard to the state of the art, it is not obvious to a person skilled in the art". For this reason the Appellant's objection pursuant to Article 56 EPC, which is not assessed in the light of the state of the art, is unfounded.

5.5 The Board is also satisfied that none of D2 to D5 either taken alone or in combination, even if taking into account the skilled person's common general knowledge can lead in an obvious manner to the subject-matter of claims 1 and 5 of the main request.
