T 1349/08 (Hydrocarbon preparation/AGIP PETROLI) 16-03-2010

1. The question of whether the present appeal is admissible and whether the decision of the Examining Division dated 20 May 2008, hereinafter referred to as the "decision", was a genuine decision in the sense of Article 106(1) EPC need not be decided upon in the present case, as the appeal is in any case not allowable.

2. Party status of Appellant

2.1 The Examining Division, in a decision dated 5 July 2002, corrected the decision to grant a European patent issued on 7 February 2002 pursuant to Rule 89 EPC 1973.

On a request of the Appellant, the Examining Division, in a "decision" dated 20 May 2008, decided that the Appellant was not a party to examination proceedings and was thus not entitled to request reinstatement of the original decision to grant and all its requests were thus rejected as inadmissible.

2.2 The object underlying this dispute is the request of the Appellant to the Examining Division to cancel its decision to correct the decision to grant and to reinstate its original decision to grant.

Thus the present dispute lies within the framework of examination proceedings, the Appellant's request being directed to the Examining Division and the "decision" under appeal dated 20 May 2008 being issued by the Examination Division.

The question arises, whether the Appellant, being neither the applicant nor the patentee, could nevertheless become a party to the examination proceedings.

2.3 The correction of the decision to grant a European patent as well as the decision refusing the Appellant's request to withdraw said decision to correct and to reinstate the original decision to grant underlying the present dispute belongs to the examination proceedings pertaining to said European patent and have been taken by the competent Examining Division. Examination proceedings are ex parte proceedings between the European Patent Office and the applicant/patentee (see Articles 60(3) and 94(3) EPC). Analogous to Article 115 EPC, which stipulates that a person submitting observations concerning the patentability of an invention shall not be party to the proceedings before the EPO, a person contesting the allowability of a correction of a decision to grant a European patent under Rule 140 EPC 2000 and requesting reinstatement of the original decision to grant, cannot thereby become a party to the proceedings. The Appellant, being neither the applicant nor the patentee, thus cannot be party to the examination proceedings.

Therefore the Appellant, not being party to the examination proceedings, has no party status in the present examination proceedings.

This was the conclusion of the Examining Division in its "decision" of 20 May 2008 and the Board shares this view. Consequently, irrespective of whether or not the Appellant is adversely affected by said "decision", it cannot acquire the quality of party status to the examination proceedings.

2.4 Therefore, the appeal is to be dismissed.

2.5 For the following reasons, the Board is not convinced by the Appellant's submissions as to why it should indeed be regarded as a party to the examination proceedings.

2.5.1 The Appellant submitted that it was at least a party to the opposition proceedings concerning the patent in suit, that these opposition proceedings were affected by the "decision" of the Examining Division dated 20 May 2008 not to reinstate the decision to grant dated 7 February 2002, and the Appellant was adversely affected thereby in these opposition proceedings.

However, the party status of an opponent in opposition proceedings cannot be transferred to examination proceedings, opposition proceedings and examination proceedings being separate proceedings (see T 198/88, OJ EPO, 1991, 254, point 2.1 of the Reasons). Whether the opposition proceedings are affected or not by a decision issued in the course of examination proceedings is irrelevant to the matter of whether the Appellant, who is opponent in opposition proceedings, may acquire party status in the examination proceedings in view of the separate nature of these proceedings. The submission that the Appellant might be adversely affected by the "decision" of the Examining Division dated 20 May 2008 may give the Appellant an interest to act, but is irrelevant to the legal question of party status, an interest to act not in itself conferring party status in proceedings to which the Appellant was not a party.

2.5.2 The Appellant further argued that in the particular circumstances of this case it was indeed party to the examination proceedings because the Opposition Division, by virtue of its decision of 17 September 2004 cancelling the date for oral proceedings already fixed and indicating that a new date would be fixed after the requested decision of the Examining Division had become final, had thereby recognised that the Examining Division should address the Appellant's request for an appealable decision by the Examining Division regarding the decision to correct the decision to grant dated 5 July 2002, the Appellant hereby acquiring party status.

However, irrespective of whether or not the communication of the Opposition Division dated 17 September 2004 bore all the characteristics necessary for qualifying as a decision and, thus, could in fact constitute a decision, and whether or not the Opposition Division indeed had the power to refer the case back to the Examining Division, examination proceedings are ex parte proceedings (see point 2.3 above) which are separate from opposition proceedings (see point 2.5.1 above) which by nature are inter partes proceedings. As such, no action of the Opposition Division could confer party status to an opponent in examination proceedings on the same case, it indeed being questionable whether or not opposition and examination proceedings may coexist for the same application/patent.

2.5.3 The Appellant further submitted that correction of a decision to grant a European patent did not form part of the examination proceedings but was an isolated procedural measure, citing J 27/96 (loc. cit.) in this respect, thus the Appellant was entitled to be party to this isolated procedural measure.

However, decision J 27/96 is concerned with Rule 88 EPC 1973 (Rule 139 EPC 2000), which applies to corrections of errors in documents filed before the European Patent Office, whereas the Appellant is objecting to a decision concerning a correction under Rule 140 EPC 2000 (Rule 89 EPC 1973), which applies to decisions of deciding bodies of the EPO. In any case, the Appellant cannot be party to an isolated procedural measure, but only to proceedings as a whole, the decision J 27/96 merely stating that the applicant which requested a correction of a mistake in documents was not thereby reinstated in a particular procedural phase which would thereby have made said whole procedural phase available to him again. Thus, the decision J 27/96 is not relevant to the present case, the correction of a decision to grant a European patent being within the scope of examination proceedings.

2.5.4 The Appellant cited Article 125 EPC, stating that if the European Patent Office were to take into account the principles of procedural law generally recognised in the Contracting States, the Appellant would become a party to the examination proceedings.

However, the Board notes that Article 125 EPC provides for taking such principles into account only in the absence of procedural provisions in the EPC. This Article thus does not refer to the absence of a procedure but only to the absence of procedural provisions. Since there is no procedure in the EPC for creating party status for a third party in examination proceedings, indeed on the contrary, it is specifically provided for in Article 115 EPC that a third party shall not be party to the proceedings before the EPO (see point 2.3 above), there can be no absence of procedural provisions. In any case, the Appellant did not substantiate its argument and did not provide corroborating evidence that in the majority of, or in any particular Contracting States, there existed some modus for creating party status for a third party in examination proceedings on patent applications. Thus regardless of whether procedural provisions are absent in the EPC, the absence of such provisions being a prerequisite for the application of Article 125 EPC, the Board concludes that in the absence of any evidence of relevant procedural principles from the Contracting States, said Article cannot serve as a basis for creating a special legal remedy making it possible for a third party to attain party status in examination proceedings (see G 1/97, OJ EPO 2000, 322, point 3 of the Reasons).

2.5.5 The Appellant submitted that its legitimate expectations had not been protected, the published text of the patent it had opposed, namely European patent No. 952 132, having been amended post-grant in an unallowable manner, the Appellant being adversely affected thereby as it was now prevented from challenging the post-grant amendment in opposition proceedings under Article 123(3) EPC.

However, any legitimate expectations the Appellant may have resulting from the publication of the decision to grant of European patent No. 952 132 may be relevant only to the opposition proceedings pending on this case (see point 5.3 below) to which the Appellant would appear to be a party, namely in its quality as opponent. Regardless of whether or not the Appellant has any legitimate expectations in the examination proceedings, legitimate expectations are not in themselves a ground for generating party status to the present examination proceedings, just as they would not be for any other member of the public, which may also have legitimate expectations in examination proceedings.

3. Since the Appellant has no party status in these examination proceedings, the appeal is not allowable, party status being a prerequisite for the Board to allow any of the Appellant's main, first and second auxiliary requests.

4. Referral to the Enlarged Board of Appeal

4.1 According to Article 112(1)(a) EPC, a referral to the Enlarged Board of Appeal is only admissible if a decision is required in order to ensure uniform application of the law or if an important point of law arises. The answer to the referred question should not be merely of theoretical or general interest, but has to be decisive, i.e. essential, to reach a decision on the appeal in question (see, for example, G 3/98, OJ EPO 2001, 62, point 1.2.3 of the Reasons).

4.2 The question put forward by the Appellant (see point VI above) concerns the issue of whether an opponent could be an adversely affected party to proceedings relating to correction of a decision to grant under Rule 140 EPC 2000 (or Rule 89 EPC 1973). Since, however, the decision for correction itself dated 5 July 2002 is not the decision under appeal in the present proceedings, but rather the "decision" of 20 May 2008 concerning the reinstatement of the original decision to grant, the answer to the proposed question cannot be decisive in the present case.

4.3 The issue addressed in the proposed question thus being merely of theoretical nature, any answer of the Enlarged Board of Appeal to that question is irrelevant for deciding on the present appeal, and hence the request for referral of the question must be refused.

5. The following comments of the Board do not form part of the ratio decidendi of this decision. However, in view of the unusual nature of this case, inter alia the following points may need attention when the opposition proceedings pending on this case resume.

5.1 Under Articles 99(1) and 101(1) EPC, the Opposition Division shall examine whether or not at least one ground for opposition prejudices the maintenance of the European patent. Thus the Opposition Division should identify the subject-matter of the patent which forms the basis of the opposition proceedings in order to determine the object of the legal dispute, this being the competence and duty of every deciding body.

5.2 Thus it appears that the subject-matter of the opposed patent should be determined. This is usually the subject-matter as defined in the published granted patent. If, as in the present case, an amendment has been carried out after mention of grant of the European patent in the Bulletin, then the deciding body, in this case the Opposition Division, may need to decide whether or not this amendment may further define the subject-matter of the opposed patent to be decided upon in opposition proceedings under Article 101 EPC.

5.3 When deciding on whether the amendment should be taken into account, the Opposition Division may need to consider whether or not the amendment carried out after publication of the decision to grant in the Bulletin (see Article 97(4) EPC) has any effect, particularly in view of any "cut-off" effect of said publication (see T 777/97, point 3, last paragraph of the Reasons and J 42/92, points 5 and 6 of the Reasons) due to the jurisdiction passing to the Contracting States from this date (see Article 64(1) EPC). The question thus may arise whether or not the Examining Division had the competence to act after this date due to an exhaustion of its competence ratione materiae as well as ratione legis. Furthermore, the interests of the public in respect of legal certainty may also have to be taken into account (see G 1/97, loc. cit., point 3(c) of the Reasons and T 713/02, OJ EPO 2006, 267, point 2.2.6 of the Reasons), the date of publication of the decision to grant in the Bulletin being the starting date for the nine month period in which opposition may be filed (Article 99(1) EPC).

5.4 If an amendment has been allegedly carried out under Rule 140 EPC 2000, the Opposition Division may need to determine whether or not said amendment was in fact a genuine correction under Rule 140 EPC 2000 (see T 1093/05, OJ EPO 2008, 430, point 7 of the Reasons and T 850/95, 1997, 152, Headnote I). The Opposition Division may indeed not have the right to verify the substance of a correction under Rule 140 EPC 2000 (see T 79/07, points 3 to 23 of the Reasons, not published in OJ EPO), but, in view of the discretionary nature of the decision to correct, it may have the competence and duty to verify whether the proper criteria were applied in determining whether the correction made did indeed qualify as a correction pursuant to Rule 140 EPC 2000, or whether the use of Rule 140 EPC 2000 as a legal basis was unjustified, e.g. the Examining Division, under Rule 140 EPC 2000, had in fact reopened examination proceedings.
