The first is the ability to understand the patent law (the agent has an advantage).
Second, it is the ability to understand technical solutions (technicians have advantages).
The third is language ability (foreign language). Patent stability mainly involves novelty, creativity and full publicity, as well as other issues involved in invalid reasons.
The evaluation of novelty and creativity is mainly through patent retrieval, understanding the situation of existing technology and analyzing the claims item by item. It is not easy to retrieve appropriate comparative literature. If it is an invention patent, the examiner has searched it.
However, it cannot be said that the comparison document he found is the closest. If any factor is different, such as the searcher, the database used and the retrieval time, the retrieval results will be different, so the analysis results of patent stability will be different.
The problem of full disclosure is the problem of patent literature itself. There are two possibilities for insufficient disclosure, one is insufficient technical disclosure, and the other is the written input of the agent.
