In almost all circumstances, an entrepreneur or startup company should NOT get a provisional patent application. The main purpose of the provisional application is to *delay* the patent process. A delay is very useful for circumstances, such as pharmaceuticals, where most of the value of the patent is at the end of the patent term. This is not the case for almost all startup companies.
First, having a patent application quickly will add value to the company. It makes business sense to get patents as fast as possible, since the company’s valuation will go up if you are raising money, and it gives the startup company at least some protection in the marketplace. I suggest using the Patent Prosecution Highway or Track One to expedite the patent to try to get a patent within 1-2 years, not the sometimes 5-7 years without expediting.
Second, a “thin” provisional application does far more damage than it helps. Many people file a 1-2 page provisional application, then think they will come back a year later and pay an attorney to write a “full” patent application. Entrepreneurs often think that they are “protected”, so they go out and freely discuss their inventions with customers, investors, and the general public during the one-year period.
This creates a situation where you have two filing dates: a first one for the provisional and a second filing date with the rest of the material.Read More
