What Are the Steps to Secure a Patent for a Software Invention in the UK?

Patents provide a form of legal protection for inventors and businesses. They allow the patent holder to have exclusive rights to use, sell, or manufacture the invention. In the field of software development, patents have become increasingly important. In the UK, the process of obtaining a patent for a software invention involves several key steps. This article will guide you through these steps, explaining what is required at each stage.

Step 1: Ensure Your Invention is Patentable

The first step in the patent application process is to confirm that your software invention is indeed patentable. According to the UK Intellectual Property Office (IPO), to be eligible for a patent, your invention must be new, involve an inventive step that is not obvious to someone skilled in the art, and be capable of industrial application.

Not all types of software inventions can be patented. The EPO (European Patent Office) states that software per se is not patentable. However, if the software provides a technical contribution or solves a technical problem, it may be eligible for a patent.

Step 2: Conduct a Patent Search

Once you have established that your software invention is potentially patentable, the next step is to carry out a patent search. This is a crucial step in the process as it will help you to determine whether your invention is truly novel.

You can conduct a patent search using various online resources, such as the database provided by the UK IPO or the EPO. These databases contain information about existing patents and published patent applications. By reviewing these documents, you can assess whether your invention is distinct from those that have already been patented or disclosed.

Step 3: Drafting the Patent Application

Having ascertained that your software invention is unique and patentable, you are now ready to draft your patent application. This is a crucial step as the quality of your application will directly influence whether your patent is granted.

A patent application typically includes the following elements: a title, an abstract, a description, claims, and any necessary drawings. The description should provide a detailed explanation of your invention, while the claims define the scope of the protection you are seeking.

Drafting a patent application can be complex, particularly when it comes to software inventions. It might be sensible to engage the services of a qualified patent attorney who specializes in software patents.

Step 4: Filing the Patent Application

Once your patent application is ready, you can submit it to the UK IPO. After filing, your application will undergo a formalities check to ensure it meets the necessary requirements.

It is important to note that filing a patent application incurs fees. These vary depending on the type of application and whether you choose to seek professional assistance. It’s worth remembering that the cost of obtaining a patent is not just a one-off expense. There are also annual renewal fees to keep the patent in force.

Step 5: Navigating the Examination Process

After filing your patent application, it will be examined by a patent examiner. The examiner will assess whether your invention meets the patentability criteria and whether the application complies with the legal requirements.

If the examiner identifies any issues, they will issue a report detailing their objections. You will then have an opportunity to respond and potentially amend your application to overcome these objections. This back-and-forth process can take several years, so patience is key.

Overall, securing a patent for a software invention in the UK involves careful planning and a thorough understanding of the patent process. From establishing the patentability of your invention, conducting a patent search, drafting and filing your application, to navigating the examination process, each step is crucial in safeguarding your intellectual property rights. While the road to obtaining a patent can be long and sometimes challenging, the potential rewards in terms of protecting your invention and securing your business interests can make it well worth the effort.

Step 6: Responding to Examination Reports

The process of examination of your patent application by the IPO is not a one-time event. Often, patent examiners issue examination reports highlighting objections or queries about your application. It’s your responsibility to respond to these reports suitably. The examination reports provide valuable insights into how the patent examiner views your invention’s patentability. Responding to these objections effectively is crucial to move the patent application process forward.

When you receive an examination report, it’s imperative to read each point carefully and try to understand the reasons behind the objections. If you’re unsure about any point, contacting the examiner for clarification can be beneficial. After understanding the objections, you need to address each one individually in your response.

In your response, you can either make amendments to your application to overcome the objections or provide arguments detailing why you believe your application should be granted despite the objections. When making amendments, ensure that you don’t inadvertently narrow the scope of your patent protection by making overly specific changes.

Engaging a patent attorney can be crucial at this stage. They can help you to frame suitable responses and make apt amendments that don’t compromise your patent protection. Remember, you typically have a set period (usually four months in the UK) to respond to an examination report. If you fail to respond within this period, your patent application may be considered withdrawn.

Step 7: Grant and Post-Grant Proceedings

If the patent examiner is satisfied with your responses and amendments to the examination reports, the IPO will grant your patent. Once a granted patent is in place, it’s essential to stay vigilant about its maintenance and protection.

In the UK, patents are granted for a period of 20 years from the filing date, provided the annual renewal fees are paid. These fees increase every year and must be paid to the UK IPO to keep your patent in force. Failing to pay the renewal fees can result in your patent lapsing.

Post-grant, it’s also critical to monitor the market for potential infringements of your patent. If you believe a third party is infringing your patent, legal action can be taken to stop the infringement and potentially recover damages. While enforcing a patent can be a complex and costly process, it’s a necessary step to protect your intellectual property.

It’s also possible that your granted patent may be subject to a revocation action by a third party. In such cases, having a patent attorney by your side can aid in defending your patent and maintaining the exclusivity it provides.


Securing a patent for a software invention in the UK is a meticulous and comprehensive process. From ensuring your invention is patentable, conducting a patent search, drafting the patent application, engaging with the examination process to securing the granted patent and maintaining it, each step is integral to the overall patenting process.

While the process can be arduous and time-consuming, the reward of having exclusive rights to your software invention, protecting it from third parties, and using it to secure your business interests makes it a worthwhile investment. Engaging the services of a qualified patent attorney from the early stages can make the journey smoother and enhance your chances of securing a strong and enforceable patent. The importance of protecting your intellectual property cannot be understated in today’s competitive tech-driven environment, and a patent provides the best form of protection for software inventions.
