Patent of shell appearance modeling

First, suppose your profitable product belongs to the patent scope of the other party, which is usually considered as infringement.

Second, the patent scheme is an overall scheme including multiple features. If your product only has the characteristics of the shell and has no other features in the patent proposal of the other party (such as claim 1), it is usually not infringing.

Third, if the patent protection scope of the other party is too large, that is, it is not worthy of the name, you can request the revocation of the patent right through the invalidation procedure.
