3. Q: How long is the limitation of actions against patent infringement, and is there any time limit for petitioning the administrative authority for patent affairs to handle patent infringement disputes?
  A:

The limitation of actions against patent infringement is two years, computed from the date when the patentee or the interested party knows or ought to know the infringing act. Like that for legal proceedings, the time limit for petitioning the administrative authority for patent affairs is also two years starting from the date when a patentee or an interested party knows or ought to know it.
