Myth Buster 4: Patent Novelty: You Published It. Did You Just Lose Your Patent?

Patent Novelty: You Published It. Did You Just Lose Your Patent?

You have spent months developing something genuinely innovative.

Then comes the exciting part. You publish the research. Present it at a conference. Showcase it at Demo Day. Put up a technical post on LinkedIn.

A few months later, someone asks:

“Can we patent this?”

That question may have come too late.

This is where patent novelty becomes critical. An invention generally needs to be new to qualify for patent protection. If key details of the invention become publicly available before an appropriate patent application is filed, that disclosure may affect its novelty and, potentially its patentability.

Surprisingly, the disclosure that creates the problem may be your own.

What does patent novelty actually mean?

Novelty is one of the fundamental requirements for patent protection.

In simple terms, the invention should not already have been made available to the public before the relevant filing or priority date. Founders often think of “prior art” as an existing patent or something published by a competitor.

But prior art can potentially arise much closer to home. Your own research paper, presentation, product demonstration or online disclosure may become relevant if it reveals the invention before filing.

That is why when you disclose can be just as important as what you invent.

How do founders accidentally destroy patent novelty?

Most founders do not intentionally give away patent rights. The problem usually arises because IP review happens too late.

Here are some of the most common situations.

1. Publishing research before filing

This is particularly common among researchers, academics and deep-tech founders.

A research paper, journal article, conference paper or thesis may disclose precisely the technical innovation that later becomes commercially valuable.

The instinctive sequence is often:

Research → Publish → Commercialise → Patent

A safer sequence may be:

Research → Assess IP → File, if appropriate → Publish

This does not mean research should not be published. It means potentially patentable innovation should ideally be identified before publication.

2. Revealing too much at Demo Days and conferences

Founders naturally want audiences and investors to understand why their innovation is different.

But there is an important distinction between explaining:

what your technology does? and revealing how the underlying invention works?

Technical diagrams, architecture, processes, prototypes and detailed demonstrations can sometimes disclose far more than intended. Hence, before presenting publicly, ask one simple question:

“Are we about to reveal something we may want to patent?”

3. Posting technical details online

A LinkedIn post may feel informal. A GitHub upload may feel routine.

From a patent perspective, however, what matters is whether information about the invention has become publicly available.

Potential disclosures can include:

• company websites and technical blogs;

• LinkedIn posts and articles;

• public GitHub repositories;

• YouTube demonstrations;

• webinars and recorded presentations; and

• publicly accessible technical documentation.

Celebrate the innovation but coordinate public communication with your patent strategy.

Assess first. File where appropriate. Post later.

4. Assuming investor discussions are automatically confidential

Startups need to speak with investors. That is commercial reality.

But not every pitch or discussion is automatically confidential. Also, there is also rarely a need to reveal every technical detail at the first meeting.

An investor may need to understand the problem, competitive advantage, performance and commercial opportunity without necessarily receiving the complete technical blueprint.

Where sensitive technical information must be disclosed before filing, confidentiality and the scope of disclosure should be considered carefully.

5. Launching first and thinking about patents later

This may be the most common startup mistake:

Build → Launch → Gain traction → Raise funding → Think about IP

By the time a patent review happens, the product may already have been demonstrated, marketed, sold or technically explained.

A simple change in sequence can preserve more options:

Build → IP Check → Protect, if appropriate → Launch

Not every innovation needs a patent.

But that decision is better made before public disclosure, rather than after discovering that valuable options may already have been lost.

Does every public disclosure destroy patent novelty?

Not necessarily.

This is where the legal position requires some nuance.

Patent laws differ across jurisdictions. Some countries provide limited grace periods for certain inventor-originated disclosures. Indian patent law also contains specific exceptions dealing with particular types of prior disclosure in defined circumstances.

However, founders should not assume that there is a universal rule allowing them to:

“Disclose now and patent later.”

A disclosure that may be protected by an exception in one country may affect patent rights elsewhere.

This becomes particularly important for startups that may eventually seek patent protection internationally.

The safer working principle remains:

File before public disclosure wherever possible.

If something has already been disclosed, however, do not automatically assume that patent protection is impossible. The exact nature, timing and circumstances of the disclosure should be professionally assessed.

Sometimes the most valuable IP advice comes before any patent application is drafted:

“Before you publish this, let us check whether there is something worth protecting.”

A short IP review before a research publication, Demo Day, product launch or technical announcement can preserve options that may be difficult — or impossible — to recover later.

Innovate. Protect. Then disclose strategically.

Planning to publish, pitch or demonstrate an innovation?

Before making technical details public, consider whether there is something worth protecting.
