Laurastar and Innosteam Swiss working flat out

Case No. S2018_003 | Hearing of 28 June 2018

UPDATE 14 July 2018:

This post initially mentioned that the prohibition to dispose of the applications at stake has been lifted. We have learned meanwhile that this was unfortunately not correct. Rather, the register ban was maintained. The post has accordingly been corrected.

Laurastar and Innosteam are litigating about ownership of two PCT applications filed in the name of Innosteam; see the announcement of the hearing here. It is pretty clear that WO 2018/006994 A1 and WO 2018/036653 A1 are at stake; see the EPO Register here and here.

The patent applications are about devices and methods for producing instant steam (WO’994) and instant hot water (WO’653), for use e.g. in devices for ironing.

Plaintiff alleges that the two patent applications pertain to subject-matter that has been invented by two of its former employees that are now employed by the defendant. On the contrary, defendant argues that the claimed subject-matter had been invented when the inventors had no longer been employed by the plaintiff. In the hearing, the role of yet another former employee of Laurastar was briefly touched who apparently changed sides, too. He is not named as an inventor in the applications at stake, but from what the defendant has argued we understand that he apparently has referred his new employer to publicly available documents (inter alia patents / patent applications) of his former employer. Further clarification in this respect may well be subject of main proceedings which are pending.

On plaintiffs request, the President of the Court had ordered the defendant in a summary judgement of 20 April 2018 (unpublished) and without hearing the defendant beforehand not to dispose of the two patent applications while the main proceedings are pending.

The hearing was remarkable for some procedural reasons.

First, an exhaustive expert opinion of the judge-rapporteur in accordance with Art. 183(3) CPC has been given orally — for the first time ever, to the best of our knowledge. This expert opinion was not favorable for the plaintiff. The parties were then given the opportunity to comment on the expert opinion immediately thereafter.

The parties were then asked for their interest in settlement discussions, but both parties denied.

Typically, this would have been it, and a decision on whether or not the interim measures are upheld would be issued in writing. Not so here. The President asked the second judge for his brief opinion, which was unfavorable for the plaintiff, too.

The prohibition for the defendant to dispose of the two patent applications while the main proceedings are pending has been upheld, for the time being.
