Patents vs Trade Secrets: Choosing the right path for intellectual property protection

In the complex landscape of IP, the choice between patents and trade secrets depends on various factors such as the nature of the invention, desired duration of protection, and available resources.

In the dynamic landscape of business and innovation, protecting intellectual property is crucial for sustaining a competitive edge. Two primary avenues for safeguarding proprietary information are patents and trade secrets. Each method offers distinct advantages and comes with its own set of considerations. This article explores the key differences between the two in order to help you and your business make an informed decision on the most suitable approach to protect your valuable assets.


A patent is a government-granted exclusive right that allows an inventor to exclude others from making, using, selling, or importing their invention for a limited period, typically 20 years from the filing date in all major countries, such as the US, Europe, UK, China, Japan etc.

Importantly, in order to obtain a Patent an invention must be novel and inventive over anything previously publicly disclosed. Additionally, the invention must have industrial applicability and not be excluded from patentability. For example, in the UK and Europe, computer games, business methods and some software inventions are excluded from patentability.

Advantages of Patents

  1. Public Disclosure: Patents require a detailed public disclosure of the invention, contributing to the body of knowledge in a particular field.
  2. Exclusive Rights: Patents grant inventors a monopoly over their invention, preventing others from using or selling the patented technology without permission in the countries the Patent is in force in.
  3. License and Monetization: Patent owners can license their technology to others, generating revenue through royalties and partnerships. Additionally, a patent is an asset that can increase the value of a business and be used as security against financial investments.
  4. Stronger protection: A patent prevents any competitor from carrying out the same invention, irrespective of whether or not the competitor later independently developed the invention. There also a number of remedies available for patent infringement, which can quickly stop competitors from carrying out an invention covered by the patent.

Limitations of Patents

  1. Cost and Time: Obtaining a patent can be a time-consuming and costly process, involving application fees, legal expenses, and potential maintenance fees.
  2. Limited Duration: Patents have a finite lifespan, after which the technology becomes part of the public domain.
  3. Public disclosure: In some situations, companies may not want to disclose all of the information of their invention. In this case, patents may be less suitable as in order to have the strongest protection as much details as possible should be disclosed in the patent.

Trade Secrets

A trade secret is confidential information that provides a business with a competitive advantage and is not generally known to the public.

Trade secrets can include formulas, processes, methods, designs, or any other information that derives independent economic value from not being readily ascertainable.

Advantages of Trade Secrets

  1. Cost-Effective: Unlike patents, maintaining a trade secret is often more cost-effective, as it does not involve application fees or legal processes.
  2. Indefinite Protection: Trade secrets can theoretically be protected indefinitely as long as the information remains confidential and provides a competitive advantage.
  3. Offers protection for a wider variety of inventions: Not all inventions are patentable since the invention must be new and inventive over any previously disclosed invention. Sometimes an invention may be new, but not inventive. In this case, a granted patent may not be obtainable, but your invention will be disclosed to your competitors. As such, it may be preferred to keep the invention a trade secret. Additionally, if your invention falls under an exclusion to patentability, for example, if it is a computer games, business methods or software, then patent protection may not be possible, and it would be better to protect the invention with a trade secret.

Limitations of Trade Secrets

  1. Limited Enforcement: Trade secrets are challenging to enforce, as their protection relies on maintaining secrecy. Once disclosed, it is difficult to regain exclusive rights and it may be more difficult to obtain a suitable remedy from any legal action in contrast with the remedies available from enforcing a patent.
  2. Reverse Engineering: Competitors may attempt to reverse engineer or independently discover trade secrets, rendering them less secure.
  3. A competitor may apply for a patent to a similar invention: If a competitor successfully develops a similar product or process, then they may choose to patent the invention, which may mean that the earlier trade secret invention may be an infringement of their patent. This may complicate your freedom to practice the invention.

Choosing the Right Strategy

Factors Influencing the Decision:

  1. Nature of the Invention: Consider whether the invention is better suited for public disclosure through a patent or if it can be effectively protected as a trade secret. For example, if the invention is unlikely to be inventive then it may be better protected by a trade secret. Alternatively, if the invention is readily reverse engineerable or the invention is readily discoverable, then it may be better protected with a patent.
  2. Duration of Protection: Assess whether a limited-term monopoly through a patent aligns with the business strategy, or if the long-term protection of a trade secret is more desirable
  3. Cost and Resources: Evaluate the financial resources available for IP protection, as patents can be expensive to obtain and maintain. However, if the invention is critical to the business and is likely to be of great interest to competitors then patent protection may be preferred due to the better enforcement options and ability to sell and license the patent.

Hybrid Approaches:

Some companies opt for hybrid strategies, combining both patents and trade secrets to maximize protection. For instance, protecting the core invention with a patent while keeping complementary processes as trade secrets. This will allow the security of protection for the key invention whilst protecting more obvious modifications, which are unlikely to lead to a granted patent, by trade secrets.


In the complex landscape of intellectual property, the choice between patents and trade secrets depends on various factors such as the nature of the invention, desired duration of protection, and available resources. Ultimately, businesses must carefully weigh the advantages and limitations of each approach to determine the most effective strategy for safeguarding their valuable innovations and maintaining a competitive edge in the market.
