1. Utility model patents are only subject to formal examination and not substantive examination, so as long as the documents meet the requirements, the patent right will be granted. Therefore, there will be duplication of the same utility model patent.
2. If you require the other party’s patent to be declared invalid, you need to apply to the Patent Reexamination Board and provide evidence proving that the other party’s patent is invalid. The Patent Search Center has an invalidation search service, and you have to do this search.
3. Regarding what materials need to be prepared, you need to analyze your patent and the other party’s patent in detail. Your agent will advise you to prepare evidence and materials.
4. Not all invalid cases will be settled. Specific cases must be analyzed in detail. As long as you have the time, energy and evidence to support it, you can do it.
