In 2009, Roche filed a second law-suit before the Delhi High Court, against NATCO for the violation of the same patent. This was followed by two more law-suits against Glenmark and Dr. Reddy’s in 2010, both of which were also filed before the Delhi High Court. This was followed by another lawsuit before the Madras High Court against Matrix and in which matter the Madras High Court granted an ex-parte interim injunction against Matrix. To the best of my knowledge this interim injunction is yet to be vacated by the Madras High Court.
Now, in 2011, Roche has filed another 4 lawsuits before the Delhi High Court against Oncare Life Sciences, Aureate Healthcare Pvt. Ltd., Innova Life Sciences Pvt. Ltd., Accura Care Pharmaceuticals Pvt. Ltd for the infringement of the same patent. Another lawsuit has been filed against Intas before the Madras High Court. That’s a total of 10 lawsuits for one patent and only one interim injunction so far by the Madras High Court. Interestingly Roche has also split the litigation between two law firms with the last 4 lawsuits before the Delhi High Court being handled by the Corporate Law Group (CLG), a Delhi based law firm. Let us see how exactly these matters proceed in the future.
