SPC Clarifies Prosecution History Estoppel, Overturns Non-Infringement Ruling in Rose Packaging Patent Case – (2024) SPC IP Civil Final No. 405
The Supreme People’s Court (SPC) overturned a first-instance judgment in a patent infringement case involving a German packaging company, clarifying the application of the prosecution history estoppel principle.
