June 25th, 2008 What Type of Patent Application Shoud I File |
There are multiple types of applications for patent protection that are available. Two of the more common are Utility (Provisional and Regular) and Design. The difference between design patents and utility patents is that design patents only protect the non-functional appearance of a product, while utility patents cover how your invention works. For some products both patent types may be available. The main advantage of design patents is they are relatively inexpensive to obtain. The main disadvantage of design patents is the scope of protection is generally narrow – they only cover the appearance of the product shown in the drawings, and not the product’s function.
If a utility patent is appropriate for your invention, then you need to decide whether to file a regular application or a provisional application. Because of their lower initial cost, provisional patents can be more attractive to start ups. Some of the more significant pros and cons of filing a provisional patent include:
ADVANTAGES OF A PROVISIONAL APPLICATION
1. Slightly Lower Initial Cost. The initial cost of preparing and filing a provisional patent application generally is lower than that of preparing and filing an actual patent application. This is because of the lower PTO filing fees and the more limited requirements of a provisional application.
2. Delay of Examination Costs. Since a provisional application is not examined by the PTO, examination costs are delayed during the pendency of the provisional application.
3. Shift of Patent Term. The end of the patent term can be shifted one year into the future, an important advantage for inventions, such as drugs, whose commercial value may be at the end of the patent term.
DISADVANTAGES OF A PROVISIONAL APPLICATION
1. Delay in Issuance of a Patent. A provisional application cannot result in a patent— an actual application will eventually have to be filed. Accordingly, the initial filing of a provisional application, instead of the immediate filing of a regular application, necessarily delays the issuance of any resulting patent.
2. Higher Total Cost. The overall cost of initially filing a provisional application and then following up with the filing of an actual application will necessarily be more than the immediate filing of a regular application.
3. Accelerated Foreign Filing Costs. Filing a provisional patent application starts the one-year period within which foreign patent protection must be applied for.
