One of the first questions I ask when a potential client brings me an invention is simple: Has anyone seen this yet? The answer matters more than most inventors realize.
Novelty is a foundational requirement in patent law. For an invention to be patentable, it must be new, meaning it cannot have been publicly disclosed, published, or offered for sale before the patent application is filed That sounds straightforward, but there can be complexities involved in the analysis of prior art to determine whether it anticipates or renders an invention obvious.

When does disclosure become a problem?
A common mistake I see from inventors is waiting too long to file their application or making a public disclosure of the invention before filing one. For example, an inventor shares a prototype with a potential partner, presents at a conference or trade show, or puts a product on the market—and only then thinks about filing. Under the on-sale bar, once a public disclosure has occurred, the inventor has a limited window to file a patent application before the right to do so is lost. And in the meantime, a public disclosure may enable others to file their own patent applications on the same or similar technology first.
What makes this even more complex is that the legal questions around novelty are far from settled. Over the last several years, novelty has taken a prominent role in Federal Circuit appeals. Courts have been wrestling with nuanced questions—whether a disclosure qualifies as experimental use, whether it constitutes a public sale, and how those distinctions affect a patent’s validity. These are not theoretical debates. They play out in real cases with real consequences.

If you believe you have a novel invention, consult a patent litigation attorney promptly. And if a prior disclosure may have already occurred, reach out as soon as possible to assess how it affects your application timeline and overall strategy.
