Summary of Facts and Submissions

I. The opponent has appealed the Opposition Division's decision, dispatched on 14 October 2013, to reject the opposition against European patent No. 2 083 723.

II. In particular, the Opposition Division decided to disregard the following documents filed with the notice of opposition:

D1: "TriGen Stable-Lok Nut & Washer", Smith & Nephew;

D2: "TriGen IM Nail System - Knee Nail for Retrograde Femoral Mode", T A Russell and R W Sanders, Smith & Nephew.

It held that in particular an affidavit by Mr Ferrante, a Vice President of one of the divisions of Smith & Nephew, did not prove that these documents were comprised in the state of the art. The prior use of the product to which D1 and D2 related, alleged in the affidavit, was disregarded as late-filed. Since the arguments presented in support of the opposition all depended on D1 or D2 being comprised in the state of the art, the grounds for opposition were not substantiated if these documents were not to be considered.

III. The notice of appeal was received on 20 December 2013. The appeal fee was paid on the same day. The statement setting out the grounds of appeal was received on 24 February 2014.

With the statement of grounds the appellant filed a further document - D4 - allegedly providing a statement of sales of the TriGen Stable-Lok Nut and Washer as disclosed in D1 and affidavits by Mr Krech, a Group Product Manager of one of the divisions of Smith & Nephew, and Mr Russell, an author of D2, in order to prove the prior art nature of D1 and D2 and the prior use of the product to which they related. It argued that D1 and D2, as well as the product to which they related, should be entered into the proceedings as prior art, if necessary after hearing as witnesses Mr Ferrante, Mr Krech and Mr Russell.

The appellant requested that the decision be set aside and the patent be revoked in its entirety or, in the alternative, that oral proceedings be held. It further requested that Mr Ferrante's affidavit be entered into the proceedings in full.

IV. The respondent filed a reply to the statement of grounds with letter received on 3 July 2014.

It requested that the appeal be dismissed or, in the alternative, that the patent be maintained on the basis of one of the first to tenth auxiliary requests filed with the reply. In the event that the Board were to decide not to dismiss the appeal, the respondent requested oral proceedings.

V. With communication dated 29 April 2015 the Board expressed its intention to remit the case to the department of first instance for further prosecution.

In response to the Board's communication both parties withdrew their requests for oral proceedings on condition that it was decided to remit the case.

VI. Claim 1 of the patent as granted reads as follows:

"A device for securing an intramedullary implant (11) within a bone (14), comprising a bolt (1;6) having a first portion extending proximally from a distal end (3) of the bolt and a second portion extending proximally from a proximal end (4) of the first portion to a proximal end (7) of the bolt (1;6), the length of the bolt being selected to substantially match a thickness of a portion of bone through which it is to be inserted and the length of the second portion being selected to substantially equal the distance from a point on an outer surface of the bone through which the bolt is to be inserted into the bone to an outer surface of the implant so that, when the bolt is fully inserted into the bone, the distal end of the second portion abuts an outer surface of the implant; and wherein the second portion of the bolt (1;6) is provided with a substantially helical exterior thread (9),

characterized in that

the bolt (1;6) comprises a first elongate member (1) including a first thread (2) extending along an exterior thereof and - as said second portion - a second elongate member (6) including a lumen (16) extending therein from an opening in a distal end thereof, the lumen (16) including a second thread (10) extending along an inner wall thereof, the first and second threads (2,10) and the diameters of the first and second members (1,6) cooperating so that a proximal portion of the first member (1) is threadably coupleable within the lumen (16), a distal portion of the first member (1) extending distally beyond a distal end of the second member (6) to form the said first portion of the bolt (1;6)."

VII. The appellant's arguments may be summarised as follows:

D1 and D2 were commercial brochures each bearing a production date anterior to the priority date of the patent. In the proceedings at first instance the appellant had already filed an affidavit by Mr Ferrante stating that D1 and D2 had been sent to prospective clients and that the product to which they related had been released on the market prior to the priority date of the patent. At the oral proceedings the Opposition Division decided that the affidavit was not sufficient to prove the publication date of D1 and D2 and refused a following request to hear Mr Ferrante as a witness.

However, Mr Ferrante's statement in the affidavit was quite clear, and the appellant had been taken by surprise when told for the first time at the oral proceedings that the affidavit did not prove the relevant prior art nature of D1 and D2. The affidavit had then become central to the appellant's case, so the request to hear Mr Ferrante himself as a witness should have been admitted.

Moreover, since establishing the prior art nature of D1 and D2, and the product to which they related, was crucial for the appellant's case, D4 and the affidavits presented with the statement of grounds should be duly considered, or, at least, the requests to hear Mr Krech and Mr Russels as witnesses should be admitted.

VIII. The respondent's arguments may be summarised as follows:

Neither the affidavits nor document D4 provided a basis for the alleged dating of D1 and D2 and the product to which they related. Moreover, the affidavits by Mr Krech and Mr Russell were late-filed.
