Warnings and pitfalls for the provisional patent application (PPA)

There are many advantages to the provisional patent application (PPA) and many of our clients use them as their first patent filing, however, there are some disadvantages that can have serious consequences for inventors. In this blog post, we’ll unveil the hidden pitfalls of provisional patent applications.

  1. Lack of Legal Protection:

    • Provisional patents provide no legal protection on their own. They merely serve as a placeholder for a non-provisional patent application.
    • Competitors can freely copy your invention during the one-year grace period of your PPA.

  2. Limited Time for Refinement:

    • You have just one year from the date of your provisional patent application to file a non-provisional patent.
    • Rushing the development process may result in a less polished invention.

  3. Incomplete Specification:

    • Provisional patent applications don’t require detailed claims so they are often lacking key information if they were not written properly (note that here at PatentFile we write our provisionals with full legal descriptions making them valid priority documents available for later use).
    • This can lead to insufficient protection for your invention, leaving room for legal disputes.

  4. Reduced Deterrence:

    • Potential infringers or investors may not take provisional patents as seriously as granted patents.

  5. Hidden Costs:

    • While provisional patents are less expensive initially, the costs can escalate when filing a non-provisional application.
    • Legal and professional fees add up, making it less cost-effective in the long ru
