Quia timet injunction storm: Delhi HC grants injunction against Ranbaxy in Galvus (Vildagliptin) case


As the mint reports; in response to a quia timet suit filed by Novartis, the Delhi high court issued an order Restraining Ranbaxy from manufacturing and selling a generic version of Vildagliptin (Galvus). Interestingly the court observed the fact that Ranbaxy had applied for revocation of Novartis’ patent shows that the defendant (Ranbaxy) wants to launch the compound patented.

Novartis was represented by senior advocate and former Solicitor General Gopal Subramanium and Ranbaxy was represented by senior advocate and former finance minister P.Chidambaram.

Novartis has been jealously guarding its blockbuster antidiabetic from generic competition. In the recent past Novartis had filed a flurry of quia timet suits against 6 generics Wockhardt,Biocon, Glenmark, Alembic pharmaceuticals, Bajaj  healthcare, Cadila healthcare.  We had blogged about these suits in detail here and here.This post aims to explore standards of proof for allowing quia timet injunctions in various jurisdictions.

Standard of proof for quia timet injunctions:

As we all know, quia timet Injunction is an injunction to restrain wrongful acts which are imminent but have not yet commenced. The standard of proof for quia timet injunctions and what constitutes genuine threat for infringement is still ambiguous in India. Aparajita has written an incisive post on Delhi HC and Madras HC decisions on quia timet patent injunctions. These cases did not explore the standard of proof for quia timet injunctions but were decided on jurisdiction.As readers may recall Shamnad has discussed quia timet actions in detail over here.

I couldn’t find the order yet, but the Mint article appears to suggest that the court granted the quia timet injunction against Ranbaxy based on the fact that Ranbaxy had applied for revocation of Novartis patent in Intellectual Property appellate board (IPAB). Novartis also produced a study it had commissioned that quotes a manager at Ranbaxy saying that “vildagliptin is at the developmental stage and is being actively pursued for development”.

For the previous cases (Bajaj and Alembic) the standard of proof adopted by the courts for allowing quia timet injunctions was: marketing approvals/ regulatory licenses obtained by generics much ahead of patent expiry.

There is no definite way of ascertaining whether a particular act constitutes proof of imminent threat. For example in the current Ranbaxy case; the court opted for a liberal interpretation, allowed a quia timet injunction and observed that applying for patent revocation is indicative  of imminent intent to launch of generic version. However one could argue either way. Applying for patent revocation may also be construed as an act of good faith by the generic company; to have the validity of the patent adjudicated before launching the generic version.

Viewing Quia timet suits through the lens of European doctrines

Merck, Sharp & Dohme Corp. and Bristol-Myers Squibb Pharmaceuticals Ltd vs. Teva Pharma in the UK is an interesting quia timet suit.

Efavirenz, a drug used to control HIV infections patented by Merck was set to expire on 3 August 2013. Teva received  marketing authorization for generic efavirenz in EU in early 2012.When BMS questioned Teva about its intentions to launch a generic version ahead of patent expiry, Teva remained silent and maintained that its policy was not to divulge commercial information to competitors.

BMS filed a quia timet suit in UK alleging that Teva’s actions of obtaining marketing approval much ahead of patent expiry, refusing to divulge intentions about launch indicate an intention to launch and infringe BMS’s patent.

The judge granted BMS an interim injunction and opined that the fact that  Teva had taken the trouble to obtain marketing approval much ahead of time (22 months)  supports an inference that Teva intended to launch  generic efavirenz before patent expiry. Also Teva’s past at risk launches also worked against them.

Conclusion:

Standard of proof for allowing quia timet injunctions are subjective. I believe that obtaining regulatory approvals/marketing authorizations much ahead of patent expiry may be indicative of imminent intent to launch, but a patent revocation petition alone is insufficient to establish whether threat to launch is imminent. In any case Section 106 of the patent act along with Section 105 provides adequate relief to persons who have been subjected to groundless threats of infringement.

The next hearing for this case is on 28th October. Watch this space for more!

    Can there be damages in a quiet timet action? Are there any decided cases where the courts have granted damages in a quiet timet action. If plaintiff values the releif of damages on the basis of which the pecuniary jurisdiction of a court is determined, does suit lie in that court? Can a person suffer damages merely on the ground of defendant seeking the registration of a deceptively similar mark, defendant admittedly not having used the trade mark so far ?

    Hi Mohan,

    Thanks for your comment.

    Quia timet Injunction is an injunction to restrain wrongful acts which are imminent but have not yet commenced. The nature of a quia timet action is such that the defendant contemplates use but hasn’t commenced actual use. I believe without use, there are no damages.

    This is an interesting trademark case re quia timet damages: http://www.indiankanoon.org/doc/40024869/

    Is it correct that a Hyderabad Court gave an injunction to Novartis against MSN Laboratories without any Bolar exemption?

    Madhulika, I have read the judgment in KRBL case, where it has been stated that no case has been brought to the notice of the court where damages have been awarded in a quia timet action. In the given case also the court has not awarded the damages. Is there any judgment where damages have been awarded? May be there is one which was not in the knowledge of the counsel appearing for the plaintiff in the referred case.
    Secondly, if the damages cannot be awarded in quia timet action, then am I right in my thinking that because the pecuniary jurisdiction of the court has been invoked on the basis of the damages in quia timet action and minus the said relief of damages, the valuation of the other reliefs for the suit is less than the pecuniary jurisdiction of the said court, the court would have no jurisdiction?
