How to apply for a patent in Nanjing

If you don't understand, you'd better find an agency to handle it for you, because if you don't write the patent claim professionally, even if you apply, it will be a waste patent. Generally speaking, most of the patents are utility models, and the easy approval of new models is a transformation of the existing technology, only for physical objects. In addition to formal examination, invention patents also involve substantive examination, which takes a long time and is difficult to obtain approval. However, if it is a formula or method, you must apply for invention II, not utility model. The approval time is also different, but the utility model was invented in about 10 months, which can wait for 2 years. No matter whether you apply for a utility model or an invention, the Patent Office will give you an acceptance notice on the day of application, which is different from a trademark. In addition, the official fee for utility model is one-off, while the invention is charged twice. Of course, if you find an agency, you can also pay it in one lump sum and let the agency handle it in full, which is safer.
