1, patent applications are divided into invention patents, utility model patents and design patents.
2. Protect content
Invention patents mainly protect material composition, preparation method and breakthrough structural transformation.
The utility model mainly protects the product structure.
Design is to protect the appearance and protect its appearance.
3. Time of application and approval
After the patent application is submitted, you can get the acceptance notice. If your patent is finally authorized, its protection date will start from the date of your application.
Generally, the longest examination and authorization time of invention patents is about 30 months, because invention patents have to go through two stages: preliminary examination and substantive examination. Utility models and designs are only preliminary reviews.
The examination and authorization time of utility model is generally about 10 month, and the patent office does not do retrieval and comparison work (that is, substantive examination), so the time is short, and its protection is not as good as that of invention patents.
The authorization time of design examination is generally about 6 months, and the Patent Office does not conduct retrieval and comparison work (i.e. substantive examination), so the time is short.
The above time is normal review time. If it is necessary to speed up the trial, it is necessary to go through the corresponding accelerated procedures, so the review time will be shortened accordingly. In addition, if the invention patent is submitted at the same time as the application, the authorization process can also be accelerated.
