“盘”与“碟”之辨：AGA公司专利无效行政诉讼案

Administrative case involving invalidation of AGA＇s patent： debate on ＂plate＂ and disc＂ shapes

AGA公司拥有的名称为“通过经皮导管导向的血管内阻塞装置”的97194488P号发明专利权。该专利是一项改进发明，本案争议焦点是该专利与基础专利相比是否具有创造性。

AGA was the owner of the patent 97194488.1 for the invention of ＂percutaneous catheter directed intravascular occulsion devices＂, which was an invention of improvement, and what was at issue in the case was whether said patent possessed inventiveness compared with its basic patent.
