“The fact that there may be proceedings both in the national courts and before the EPO is inevitable as patent rights, both under the Convention and under the Act, are national rights to be enforced by the national courts with revocation and amendment being possible in both the national courts and in certain circumstances before the EPO. That overlap can mean that there are parallel proceedings in this country and the EPO with the potential for conflict. It is desirable for that to be avoided. Therefore the Patents Court will stay the English proceedings pending a final resolution of the European proceedings, if they can be resolved quickly and a stay will not inflict injustice on a party or be against the public interest. Unfortunately that is not always possible as resolution of opposition proceedings in the EPO takes from about 4-8 years.”
“It is not sensible for a court in this country to allow proceedings to be heard in this country which duplicate those in the EPO unless justice requires that to happen. At the time that the 1977 Act was enacted, it was envisaged that proceedings before the EPO would be concluded with reasonable expedition. The consequence would be that any overlap between EPO proceedings and national actions could be prevented by staying the proceedings in this country for a short period. In some cases the Patents Court has refused to stay proceedings in this country, despite the obvious desirability of taking that action, because of the injustice that a stay would cause. In the present case it is hoped that the EPO appeal decision would be available by 2001. These proceedings are due to be heard in May 2000.”
“What I take from these decisions is that there is an emphasis or presumption in favour of a stay but not where to do so would cause injustice.”
“I have no doubt that Mann J was right. There is a presumption in favour of a stay. However, that does not mean, as at times appear to be suggested on this application, that this is a difficult presumption for a party resisting a stay to overcome. Absent any other consideration, there are obvious advantages in only having one set of proceedings rather than allowing two to be pursued simultaneously. The proceedings in the EPO may result in the patent being held invalid, in which case the English proceedings would become redundant. Therefore, absent any other consideration, a stay is the appropriate course to adopt. But when there are other considerations, it is for the court to weigh up the pros and cons and see where the justice of the situation lies.”
“I. Not to sue the Claimant during the period of the stay of the UK action for any act of infringement of the Patent in the UK. II. Not to seek any financial relief other than damages on infringing items in respect of any acts of infringement of the Patent committed by the Claimant in the UK. III. Not to seek any injunctive relief in the UK or delivery up in the UK against the Claimant in respect of any act of infringement of the Patent in the UK. IV. Not to sue or threaten to sue the Claimant’s customers in respect of any acts of infringement of the Patent in the UK in relation to goods acquired from the Claimant in the UK during the period of the stay of the UK action. V. Not to seek any financial relief other than damages on infringing items against the Claimant’s customers in respect of any acts of infringement of the Patent in relation to goods acquired from the Claimant in the UK. VI. Not to seek injunctive relief in the UK or delivery up in the UK against the Claimant’s customers in respect of any acts of infringement of the Patent in relation to goods acquired from the Claimant in the UK. VII. To prosecute the EPO proceedings diligently.”
“Furthermore, there is an advantage of proceedings being conducted here in accordance with the fairly tight timetables which are now imposed, namely that judgments obtained from this court, or obtained from this court and then from the Court of Appeal on issues of infringement and validity have in the past, at least on occasions, helped to inform the parties so as to enable them to resolve their disputes of a worldwide basis earlier rather than later.”
