How do you know if you have something patent-worthy? More importantly, how can you determine if you have something patentable before you invest hours of effort and sink $10K or more into lawyer fees?
Though complex and nuanced, the legal standard for a patent can be summarized into three core requirements:
Being useful means:
If your invention does something and that something is specific and credible, your invention is most likely useful.
For your invention to be novel, two thresholds matter:
New to the Public Domain. Have you ever disclosed your invention in any media or publication, used it publicly, or offered it for sale to the public? You should file a patent application before doing any of these if possible.
If you’ve already disclosed your invention, the US allows a 12 month grace period whereas many international jurisdictions don’t allow any. It’s best to check with a lawyer if you’re unsure what applies to you.
At Least One Difference. Your invention is not novel if each and every element of the invention is found in a single prior art reference.
Prior art is anything made available, or disclosed, to the public prior to the patent filing date that might be relevant to an invention, which includes:
Prior art comprises of hundreds of millions of documents and it’s impossible to review them all. Find at least one significant differentiator and be as precise and honest with yourself about these as possible.
Does your invention:
Most patent applications are rejected because they’re considered obvious.
The patent examination process assumes that the novel aspects of most inventions come from:
To show that your invention is a combination or substitution, patent examiners will first look for prior art references that are similar or analogous to yours, then mix or match them to replicate your invention.
To show that your invention is obvious, examiners will then consider the rationales or motivations that one of ordinary skill in your field might have to actually mix or match.
To get around this, its important to understand how a patent examiner might interpret and decompose your invention. You can’t know with certainty what prior art an examiner will find but you can be judicious in identifying what could be seen as relevant or analogous to your invention in some way. You can then be intentional about counteracting it.
How to do this is a discussion for next time.
