What is prior art and how does it affect my patent application?

Imagine discovering a revolutionary new invention, only to find out someone else had the same idea decades ago. Disheartening, right? That is where prior art comes in – a crucial concept in the patent world that can make or break your application.

So, what exactly is prior art?

Put simply, it is any information publicly available before your invention's patent filing date that describes something similar. Prior art is any evidence that your invention is already known. It does not need to exist physically or be commercially available. It is enough that someone, somewhere, sometime previously has described or shown or made something that contains a use of technology that is very similar to your invention.

The prior art includes:

For example, consider an invention relating to a new or novel metallic water bottle with a temperature indicator. For this invention, as an illustration, these can be relevant prior art (a) US20240041250A1 - Drinkware with active temperature control (b) WO2016133421A1 - Baby food bottle warmer with temperature control (c) Non-patent literature, HB Plus 500ml Smart LED Temperature Display Stainless Steel Vacuum Mug Water Bottle Cup.

Prior art can significantly impact your patent application in several ways:

Novelty: One of the key requirements for patentability is novelty, meaning the invention must be new and not disclosed in prior art. If prior art exists that is identical or very similar to your invention, your application will likely be rejected citing the presence of such prior art.

Non-obviousness: Even if your invention is not identical to prior art, it still needs to be non-obvious. This means it would not be considered an obvious combination or modification of existing technologies by someone with ordinary skill in the field. If prior art suggests such a combination, your application might face challenges.

Here are some benefits of prior art:

Strengthening your application: By acknowledging and addressing relevant prior art in your patent application, you demonstrate a strong understanding of the subject matter and highlight the unique features of your invention. This can improve its chances of approval. Avoiding future challenges: Identifying and discussing potential prior art upfront can help avoid future legal issues down the line if someone challenges your patent based on undisclosed prior art.

Overall, prior art plays a crucial role in the patent application process. It is essential to conduct a thorough prior art search in order to assess your invention's novelty and non-obviousness and avoid surprises during the application process.
