As mentioned in my previous blog entry dated 23 January 2012, the DKPTO announced that due to user demand efforts to establish a PPH-agreement with the Russian Patent Office had been initiated.
Now, the efforts have matured into a PPH-agreement between DKPTO and ROSPATENT, which entered into force on 1 February 2012. Prosecution via the PPH agreement may not only be requested at both offices based on national work products, but also at the DKPTO, based on work products from ROSPATENT acting as an international searching or preliminary examination authority under the PCT.
I can also add that another PPH agreement entered into force on 23 January 2012, namely between China’s SIPO and Germany’s DPMA.
