Brief description of the notified legal text  
The Patent Act, as amended by: Act No. 36 of 2014,  An Act to amend the Patent Act, Design Act, 
Trademark Act, the Act on International Applicatio ns under the Patent Cooperation Treaty and the 
other act 
 The Patent Act was revised to take relief measures so that applicants are entitled to extend 
certain periods required for filing, examination, and other procedures when they have compelling 
reasons, e.g., following disasters, etc. This am endment also creates a new system for submitting 
an opposition to a granted patent, so as to realize the stability of patent rights earlier.
