To protect a novel and beneficial invention, you should consider obtaining a patent. However, it’s crucial to understand that patent eligibility has specific and rigorous criteria. Prior public disclosure of your invention can typically prevent patent approval, though some exceptions exist.

What Counts as a Public Disclosure Under U.S. Patent Law?

Public disclosure does not require an invention to be widely known. As such, even limited exposure can count as public disclosure if the invention is accessible to others without confidentiality protections. Once the details of an invention are shared, whether intentionally or accidentally, your patent rights may be limited or lost entirely.

Common Examples of Public Disclosures

  • Presenting the invention at trade shows or exhibitions
  • Pitching the idea to investors who have not signed non-disclosure agreements (NDAs)
  • Publishing descriptions or diagrams on social media
  • Offering the invention for sale or accepting preorders
  • Entering the invention into competitions or showcases
  • Sharing information with collaborators or contractors without confidentiality agreements

Why Does Public Disclosure Impact Patent Eligibility?

The central point of patent law is to protect and reward new and original inventions. As such, when information becomes publicly available, even to a small number of people, it may be treated as prior art. This can ultimately inhibit patent eligibility.

When examining the impact of public disclosure on patent eligibility, it’s important to understand that it does not simply reduce the likelihood of approval, but it can permanently bar patent protections in the event that deadlines and rules are violated. Because of their nature, patent applications are heavily scrutinized, and examiners will consider public disclosures, regardless of their intent. As such, without proper legal guidance, public disclosure can result in irreversible consequences.

Public disclosure impacts eligibility, as it effectively undermines:

  • Novelty, as the invention is no longer considered new
  • First-to-file priority if someone else files before you are able to
  • Foreign patent rights, as many countries do not offer a grace period

Because the United States operates under the first-to-file standard, applying for a patent early is generally more important than perfecting the invention first.

Is It Still Possible to Patent an Already Disclosed Invention?

Depending on the unique circumstances of your case, it might still be possible to obtain a patent even after public disclosure. U.S. patent law does recognize some exceptions, ultimately allowing inventors to preserve their patent eligibility. However, these exceptions are incredibly limited, as they depend heavily on the timeline, scope of the disclosure, and who made the disclosure. As such, understanding what actions can preserve eligibility, which can impact eligibility, and the actions that can destroy eligibility, is critical.

Actions That May Preserve Patent Eligibility

  • Filing provisional or non-provisional patent applications prior to any form of public disclosure
  • Limiting disclosures to certain individuals who have signed legally binding, valid non-disclosure agreements
  • Making disclosures that are non-enabling, meaning they do not contain technical details that would allow someone in the field to recreate the invention
  • Acting within the one-year U.S. grace period, assuming no disqualifying third-party disclosures have occurred

Actions That Destroy Patent Rights

  • Pitching the invention to an investor or partners without proper confidentiality protections
  • Publishing details, photos, and videos online
  • Relying on verbal agreements of confidentiality rather than written contracts
  • Accepting pre-orders before a formal filing date
  • Presenting the invention at trade shows or conferences without a prior patent filing

What Is the One-Year Grace Period?

In the United States, inventors are generally granted twelve months from the date of their own public disclosure to pursue a patent application. Missing the deadline can result in the permanent loss of U.S. patent rights. As such, it’s necessary to consider:

  • The grace period does not extend to include third-party disclosures
  • It does not preserve most foreign patent protections
  • It does not excuse the failure to meet other requirements under U.S. patent law

For inventors in California, it’s necessary to understand that this one-year grace period is not a safety net, as it can conflict with commercialization timelines and investor expectations. As such, brief delays in filing can completely destroy valuable patent rights.

How Can Non-Disclosure Agreements Protect Inventors?

Non-disclosure agreements (NDAs) are imperative tools that inventors can use to shield their disclosures from becoming legally public.

When Are NDAs Effective?

  • Pitching the invention to investors
  • Discussions with contractors and manufacturers
  • Beta testing
  • Product development collaborations

When Might NDAs Not Help?

  • Public trade shows
  • Marketing campaigns or online publications
  • Sales offers to the public

Should You File a Provisional Patent Application First?

A provisional patent application is an effective tool that allows inventors to establish an early filing date prior to full disclosures. It’s important to understand that this does not eventually transform into a full patent, but it can provide important placeholder protection for early inventions. A provisional patent application can help:

  • Lower the upfront cost
  • Create a one-year filing window for non-provisional patents
  • Grant “patent-pending” status

Important International Patent Risks After Public Disclosure

As mentioned, many foreign countries, including most of Europe and Asia, do not recognize the grace period following public disclosure as U.S. patent law allows. As such, if you are an inventor looking to expand into the international market should be aware that public disclosure can and will eliminate foreign patent options. As such, inventors looking for global expansion should file a patent application prior to any public disclosures.
