How to Determine the Patentability of an Invention?

Introduction

Determining the patentability of your invention is a critical step before applying for a patent. It involves understanding the legal criteria that your invention must satisfy and conducting a thorough search for any existing patents or prior art. By assessing whether your invention meets these standards, you can confidently proceed with a patent application and protect your intellectual property.

In this guide, well explore the criteria that define patentability, the steps involved in conducting a prior art search, and how to evaluate search results. We will also discuss consulting with a patent attorney and address common pitfalls in determining whether your invention is indeed patentable.

What is Patentability?

Patentability refers to the set of legal standards that an invention must meet in order to be eligible for a patent. This includes three primary criteria: novelty, non-obviousness, and utility. Meeting these criteria ensures that only inventions that genuinely advance technology or provide new solutions can be protected by a patent.

A patent grants the inventor exclusive rights to make, use, or sell the invention for a specified period, typically 20 years for utility patents in most jurisdictions. This protection prevents others from exploiting the invention without permission and provides a legal framework for resolving disputes over the invention's use.

Key Criteria for Patentability

1. Novelty

To be considered patentable, an invention must be novel. This means that it has not been disclosed to the public in any form, such as through published articles, existing patents, or publicly accessible demonstrations. If an invention has been previously described or used, it fails the novelty requirement.

The novelty criterion ensures that patents are granted only for truly new inventions. A thorough search for prior art, which includes existing patents, technical publications, and other sources, is crucial for confirming that the invention is not already known. In some cases, even slight differences in the invention's design or function may still qualify it as novel.

2. Non-Obviousness

The requirement of non-obviousness means that the invention should not be an obvious improvement or modification of existing technology to a person with ordinary skills in the relevant field. For instance, combining known techniques or making a straightforward adjustment to an existing device typically does not meet the non-obviousness standard.

To evaluate non-obviousness, patent examiners often look at prior art to see if there is any suggestion, motivation, or teaching that would lead someone skilled in the art to create the claimed invention. In essence, the invention should involve an inventive step that goes beyond routine developments.

3. Utility

Utility means that the invention must have a specific, substantial, and credible use. The invention should provide some practical benefit or solve a particular problem in a useful way. If an invention is inoperable or does not achieve the intended purpose, it may be deemed non-patentable.

For most utility patents, demonstrating utility is straightforward, as it involves showing that the invention functions as intended. However, inventions in fields like biotechnology may face closer scrutiny to ensure that they fulfill the utility requirement.

Conducting a Prior Art Search

A prior art search is an essential step in determining the patentability of an invention. Prior art includes any publicly available information that could relate to the invention's novelty and non-obviousness. This can come from a variety of sources such as:

• Existing patents and published patent applications
• Scientific articles, technical reports, and conference papers
• Books, catalogs, and manuals
• Products or processes already available on the market

The goal of a prior art search is to identify any documents or evidence that might affect the patentability of the invention. A well-executed search helps to confirm the novelty of the invention and provides insights into how it differs from existing technology.

Steps to Conduct a Prior Art Search

1. Identify Key Features of the Invention: Break down the invention into its core components and functionalities.
2. Choose Relevant Databases: Use patent databases like the USPTO, WIPO, or Google Patents, as well as non-patent literature sources.
3. Search Using Keywords and Classification Codes: Combine keywords related to the invention with classification codes used in patent databases for more precise results.
4. Review Search Results Thoroughly: Look for documents that closely resemble the invention or describe similar concepts.
5. Document Findings: Keep detailed records of the search process and findings, including the documents reviewed and how they relate to the invention.

While it is possible to perform a basic search independently, hiring a professional patent search firm can improve the comprehensiveness and accuracy of the results. Patent search professionals have the expertise to navigate complex databases and identify relevant prior art that may not be easily found using standard search techniques.

Evaluating the Results of a Patent Search

After conducting a prior art search, it is important to carefully evaluate the results to determine whether the invention still meets the criteria for patentability. Here’s how to approach the evaluation process:

1. Assess the Similarity of the Invention to Prior Art

Examine whether any prior art references describe the same or very similar inventions. If a reference discloses all of the key features of your invention, it may not be considered novel. However, if there are differences in design, materials, or methods of use, there may still be a case for novelty.

2. Determine if the Differences are Non-Obvious

If the invention is not identical to any prior art, assess whether the differences would be considered obvious to a person skilled in the art. This step often involves analyzing how the invention improves upon or modifies existing technologies.

3. Review Patentability Opinions

Obtaining a professional patentability opinion from a patent attorney can be invaluable. An attorney can help interpret the results of the prior art search and provide an opinion on whether the invention meets the legal requirements for patentability.

Consulting with a Patent Attorney

While conducting a prior art search and evaluating the results can be done independently, consulting a patent attorney brings several benefits:

• Expert Legal Advice: Patent attorneys are well-versed in patent law and can advise on the nuances of patentability criteria.
• Application Preparation: Attorneys can assist in drafting the patent application to ensure that it includes the necessary technical details and meets formal requirements.
• Navigating Office Actions: If the patent office raises objections, a patent attorney can help respond to these and argue for the grant of the patent.

Working with an attorney not only improves the chances of securing a patent but also helps in crafting stronger claims that adequately protect the invention.

Next Steps if Your Invention is Patentable

If your invention is determined to be patentable, the next steps involve preparing and filing the patent application. Here’s an overview of the process:

1. Draft the Patent Application: Prepare a detailed description of the invention, including drawings if necessary. The claims should clearly define the scope of the invention.
2. File the Application with the Patent Office: Submit the application to the appropriate patent office (e.g., USPTO for U.S. patents). Pay the required filing fees.
3. Respond to Office Actions: If the patent office requests additional information or raises objections, provide responses within the given deadlines.
4. Monitor the Patent Application Status: Keep track of the application’s progress and take action as needed to facilitate its grant.

Common Mistakes to Avoid When Determining Patentability

Avoid these common pitfalls when assessing the patentability of your invention:

• Neglecting a Comprehensive Prior Art Search: Skipping a thorough search may result in finding out later that the invention was not novel.
• Overlooking Slight Differences in Prior Art: Even minor differences between your invention and existing technology can significantly impact patentability.
• Failing to Seek Professional Advice: Trying to navigate the patent process alone can lead to missed opportunities or legal oversights.

Conclusion

Determining the patentability of an invention involves understanding the legal criteria of novelty, non-obviousness, and utility, conducting a thorough prior art search, and consulting with a patent attorney. By following these steps, you can better protect your intellectual property and maximize your chances of securing a patent.

Taking the time to properly evaluate the patentability of your invention not only saves resources but also positions your invention for a stronger and more effective patent application.
