The Delhi High Court had on January 12 banned HFCL and its subsidiaries from manufacturing and selling fiber optic cables, which Sterlite Technologies (
) claimed were based on its multi-tube technology.
“STL’s claim is without merit and HFCL has more than a strong defense to present the same in court to vacate the ex parte interim restraining order,” a spokesperson for HFCL said. “We have not only prayed for the reversal of said interim ex-parte restraining order in court, but also for the dismissal of STL’s infringement claims. We will also protect our interests against any such future claims arising from information misleading.”
In a statement on Saturday, HFCL said the product in question has been manufactured and used by companies around the world for more than 15 years, and added that the patent claims made by STL were not true.
“In fact, STL’s application for a similar patent was rejected by the European Union. HFCL has been manufacturing the micro multitube cable since 2014 to customer specifications long before STL’s patent filing date and confirms that it there is no infringement of the contested patent,” he said.
Earlier this month, alleging infringement of its patent number 335369 (variant 144F), STL filed a lawsuit in the Delhi High Court, following which the ex parte order was passed on January 12 , restricting further commercial action related to the controversial patent.
“This is to inform that Sterlite Technologies has obtained an interim ex parte injunction against Himachal Futuristic Communications in a patent infringement litigation filed in the Delhi High Court,” STL had said on Thursday.
