Summary of Facts and Submissions
I. European patent application No. 95 908 664.6 was refused by a decision of the Examining Division. The application was based on the International Application No. PCT/US95/00 969, published under No. WO 95/21 126.
II. In a communication under Rule 51(4) EPC of 15 October 1998 the Examining Division indicated that it intended to grant a patent with claims 1 to 9 filed by the appellant with the letter dated 13 August 1997. With a letter dated 12 February 1999 the appellant filed a new claim 1 which no longer contained the feature of induction heating at a frequency of 0.5 to 30 MHz, which was already present in claim 1 as originally filed. After various communications and oral proceedings the application was refused on the ground that, because of the deletion of said feature, claim 1 was amended in such a way that it contained subject-matter which extended beyond the content of the application as filed.
III. The appellant lodged an appeal against this decision. In the statement of grounds of appeal arguments were put forward why in this case it was allowable to delete said feature.
IV. In a communication pursuant to Article 11(2) of the rules of procedure of the Boards of Appeal, the Board expressed as its preliminary opinion that the deleted feature was presented in the original application as an essential feature for performing the invention so that its deletion would contravene the requirements of Article 123(2) EPC.
V. With the letter dated 4 November 2002 the appellant submitted a new claim 1 in which said feature was reintroduced and requested grant of the patent on the basis of the communication under Rule 51(4) EPC of 15. October 1998.
Reasons for the Decision
New claim 1 corresponds to claim 1 of the set of claims on the basis of which the Examining Division intended to grant the patent according to its communication under Rule 51(4) EPC. The appellant's present request can be regarded as an approval of the text on EPO Form 2035.3 sent with said communication. The reason for the refusal of the application is thereby removed. The Board sees no reason to question the finding of the Examining Division that the application with the text indicated in said communication meets the requirements of the EPC.
For these reasons it is decided:
1. The decision under appeal is set aside.
2. The case is remitted to the Examining Division with the order to grant a patent with the documents according to EPO Form 2035.3 sent with the communication under Rule 51(4) EPC of 15 October 1998.
