Sometimes one may wonder why parties bother to start an appeal procedure (or worse, write a claim and file an application). In this particular case, the applicant did not get past the Examining Division because a severe lack of clarity under Art 84 EPC. The Board did not think differently and the applicant (appellant) did not attend the oral proceedings. Just a good example of how one should not draft a claim. You can read the frustration of the Board in the decision text, and it took them 15 minutes to come to their decision. If someone knows how this HIFU system works, feel free to comment.
Summary of Facts and Submissions
I. The European patent application was refused by a decision of the examining division for reasons of lack of inventive step (Articles 52(1) and 56 EPC 1973) of the subject-matter of claim 1 of each of a main request and three auxiliary requests then on file and of lack of clarity (Article 84 EPC 1973) of claim 1 of the main request.
II. The applicant lodged an appeal against the decision.
The appellant requested that the decision be set aside and that a patent be granted on the basis of a new set of claims 1 to 10 filed with the statement setting out the grounds of appeal. Furthermore, an auxiliary request for oral proceedings was made.
III. The appellant was summoned to oral proceedings to take place on 23 July 2015.
In a communication pursuant to Article 15(1) RPBA the Board commented on the issues to be addressed during the oral proceedings. In this context, the Board pointed inter alia to a variety of clarity problems with the request on file.
IV. The appellant did not reply to the Board's observations nor did it file any further amendments. Instead, the appellant withdrew its request for oral proceedings by letter of 23 June 2015 and informed the Board that it would not attend or be represented at the oral proceedings. In addition, the appellant requested a decision on the state of the file.
V. Oral proceedings were held in the absence of the appellant.
VI. Independent claim 1 of the appellant's request reads as follows :
"1. A high intensity focused ultrasound (HIFU) system for scanning and treating tumor, comprising a combined probe, a high frequency electric power source, a B-mode ultrasound scanner, a multi-dimensional motional apparatus, a vacuum degasser, a therapeutic bed, and a computer operating system, wherein the combined probe comprises:
- a therapeutic head which generates high intensity focused ultrasound; and
- an image-displaying probe of the B-mode ultrasound scanner which is integrated with the therapeutic head,
wherein the combined probe is mounted on the multi-dimensional motional apparatus which comprises a three-dimensional rectangular coordinate and one- or two-dimensional rotational coordinate, the upper end of the combined probe being connected to a central hole of the therapeutic bed through an open water bag;
wherein the open water bag is mounted on the central hole;
wherein the lower end of the open water bag (2) is connected to the head of the combined probe (3);
wherein the combined probe (3) is further connected to the high frequency electric power source (6);
wherein the B-mode ultrasound probe is connected to the B-mode ultrasound scanner;
wherein the motional system (4) is connected to the digit-controlled scanning system;
wherein the open water bag (2) is connected to the vacuum degasser (5); wherein the computer operation system (9) is connected separately to the high frequency electric power source (6), B-mode ultrasound scanner (7), digit-controlled scanning system (8) and the vacuum degasser; and
wherein the therapeutic head can cause a temperature greater than 70 degrees centigrade in a focal region."
