Update on Bayer-Cipla patent infringement suit: Nexavar patent infringement suit before the Delhi High Court goes directly to trial

In a significant departure from the standard practice in Indian patent trials, Justice Ravinder Bhat, who is presiding over the Nexavar patent infringement suit filed by Bayer against Cipla, has ordered, on the 23rd of July, 2010, that the suit be expedited directly to trial. We had previously blogged on this case over here. In the normal course of events the Court would have first disposed the interim injunction application after which the matter would be directed to trial. This however did not make much sense in the context of patent infringement suits where it simply impossible for a judge to take a call on prima facie infringement or validity.

Justice Bhat has now ordered both parties to file expert witness affidaivts which will submitted with the remaining material to a ‘scientific advisor’ appointed by the Court under Section 115 of the Patents Act, 1970. This scientific advisor will then depose in court and be subject to cross-examination by either party. Surprisingly both parties seem to have waived their right to cross-examine each others witnesses, without even having seen other’s affidavits!!!!

Nevertheless, Justice Bhat deserves a round of applause for this judicial innovation.
The next date of hearing, for framing of issues, is on the 22nd of September, 2010.

Since I am unable to give you a direct link to the Delhi High Court website, I have pasted the entire Order below.
