Public disclosure of an invention can have a significant impact on its eligibility for patent
protection.
In most jurisdictions, public disclosure of an invention before filing a patent
application can destroy its novelty, making it ineligible for patent protection. This is because patents
are granted for new and inventive solutions, and public disclosure essentially makes the invention
public knowledge, negating its novelty. However, there are some exceptions and nuances to consider.
Many countries, including the United States, offer a grace period, typically one year from the first public
disclosure. This allows inventors to file a patent application within this window and still potentially
obtain patent protection, even though the invention was previously disclosed.
Accidental disclosures may not always be detrimental. If the disclosure was unintentional and limited in
scope, it might not necessarily destroy novelty. However, seeking legal advice in such situations is highly
recommended.
The nature and extent of the disclosure also play a role. A brief presentation at a conference might have a
different impact than publishing a detailed technical paper.
Maintaining confidentiality of your invention before filing a patent application is generally crucial to
ensure its patentability. Grace periods offer some leeway, but filing a patent application as soon as
possible after conception is highly recommended.
