2. The smaller the main right of patent claim, the smaller the scope of protection and the higher the possibility of authorization.
Specific, such as (non-real case, only write logical description),
A:
1. A cup with heat preservation function is characterized by having a heat preservation coating.
2. The coating according to claim 1 is a silver-zinc alloy.
3. The silver-zinc alloy ratio as claimed in claim 2 is 9: 1.
b
1. A cup with heat preservation function is characterized by having a heat preservation coating, and the heat preservation coating is an alloy with a silver-zinc ratio of 9: 1.
Then the main body protected by A is the thermos cup with thermal insulation coating.
The main body of B protection is the cup with the alloy with the silver-zinc ratio of 9: 1 as the thermal insulation coating.
Undoubtedly, B requires relatively few rights, and it is relatively easy to get authorization.
Supplement: you can't bring the words A company. If the technology you are based on is not your company, you must first obtain authorization, unless the technology has become well-known in the industry (no patent right or expired patent right).
If company A is your company, then the affiliation can apply for priority with the previous technology. If it is not the improvement or refinement of the original technology, there is no need to apply for priority at all.
