LONGi Won the Patent Invalidation Case (IPR) Against Hanwha in the US

XI'AN, China, June 15, 2022 /PRNewswire/ -- Recently, the United States Court of Appeals for the Federal Circuit issued an appeal decision on the invalidation of Hanwha's US patent US9893215B2, in which the court upheld the US Patent and Trademark Office's (USPTO) "Invalidation Decision", ruling in favour of the patent's invalidity. LONGi has won both the International Trade Commission (ITC) litigation and the patent invalidation case (IPR) against Hanwha in the United States thus far.

Earlier this week, the specialized Court in Paris (France), in a decision handed down by one of its most experienced patent law judges, ruled that Hanwha's seizures as conducted in France in 2021 were illegal and thus invalid on the grounds of disloyal conduct by Hanwha and ordered the release and recall of all the documents and materials that were seized and detained illegally by Hanwha. More specifically, the French Court ruled that Hanwha had acted in a disloyal manner by withholding crucial information from the French Court such as (1) the opinion issued on October 21, 2020 by the Opposition Division of the European Patent Office (EPO) ruling in favour of the invalidity of Hanwha's patent and (2) the fact that the equivalent patent claims in the US had been declared invalid by the United States Patent and Trademark Office (USPTO). 

At present, the non-infringement and invalidity proceedings in Australia litigation between LONGi and Hanwha are currently in the stage of evidence exchange and argument defence. The judge is tentatively set to hear the case in the fourth quarter of 2022. 

Furthermore, LONGi has filed an opposition to the EPO contesting the validity of the equivalent Europe patent EP2220689B1, which is still pending.
