Eli Lilly v Genentech: When does a patent infringement case turn into questions of validity? – and its impact on cost findings.
I explained the issue in  EWHC 3104 (Pat) Eli Lily v Genentech in my posting on Chugai v UCB. A defendant in a patent infringement case often tries to make the case that the suit is about patent invalidity really: for this obliges the court per GAT v Luk to refer (only the) invalidity issue to the court with exclusive jurisdiction under Article 24(4) Brussels I Recast.
Here, Eli Lily seek a declaration of non infringement of a bundle of European patents held by Genentech, a US-incorporated firm.
Birss J in the case summarises all relevant precedent, including Chugai, to reach the conclusion that the suit can stay in the UK.
Of note is his holding on costs. The English courts do not just review whether the case is currently about validity but also what the likelihood is that it will become one on validity. For if it does later on, Birss J suggests ‘this entire exercise will have been something of a charade‘ (at 84). (Which is not quite the case: even if the validity issue needs to be temporarily outsourced to different courts, the infringement issue may later return to the courts of England).
On this point, Eli Lilly refuse to disclose whether they may seek a ruling on the validity of the patents: they would rather wait to see Genentech’s defence. Not an unacceptable position, but one, High Court does warn, which will have an impact on costs. At 87: ‘I am satisfied that these unusual circumstances mean that it would not be fair to pre-empt what each party may decide to do. There are sufficient uncertainties that the right thing to do is wait and see what happens. However in my firm but necessarily provisional view that wait should be at Lilly’s risk as to costs. If Genentech does counterclaim for infringement, and validity of the non-UK patents is put in issue (here or abroad) in response, then it is very likely that Lilly should bear the whole costs of this application even if they win it in its form today.‘
That latter point is interesting. It’s twice now this week that judgments come to my attention where jurisdictional considerations are clothed in costs implications.
