When the patented product of design is a single important part, how to identify the same or similar design?

1. In the case that the patented product of design is a single important part, the accused infringing product is the same or similar to the patented product of design, and the known design part is also the same or similar, which constitutes infringement;

2. If the main parts are not the same or similar, but the well-known design parts are the same or similar, it does not constitute infringement; Where the parts are the same or similar, but different or similar to the known design parts, it does not constitute infringement.

The basis of this judgment method and conclusion is mainly based on the overall product of design, rather than the local protection of design patents.

The above is for reference only, hope to adopt ~
