Errors in Registration

October 9, 2024

The process of registering intellectual property rights is essential to ensure the protection of trademarks, patents, designs, and other creations. However, there are numerous common registration errors that can jeopardize the success of this procedure. Whether due to lack of knowledge or negligence, these mistakes can result in financial costs or missed opportunities. In Portugal, the National Institute of Industrial Property, or INPI, is the entity responsible for managing and registering related rights.

In this article, we will explore the most common registration errors, from the lack of initial preparation to the failure to renew, as well as how to avoid them to ensure the effective protection of creations and innovations.

Concept of Registration

Registration is a formal procedure aimed at protecting intellectual property rights, such as trademarks, patents, and industrial designs, among others. This process grants the holder exclusivity over the use of a creation, preventing third parties from using it without authorization.

Although not mandatory, registration is highly recommended, as it provides legal security and facilitates defense in cases of unauthorized use by third parties. Therefore, understanding the steps involved and the necessary requirements is essential to avoid errors that could compromise the validity of the registration.

Errors in Registration

The registration of intellectual property rights is an essential step to ensure the protection of innovations and creations. However, this process is not always carried out correctly due to errors that may arise at various stages. Therefore, knowing and understanding the most common mistakes is the first step to avoiding them and ensuring a successful registration.

Lack of prior research

One of the most common registration errors is the lack of detailed prior research. This step is essential to check if there are already similar or identical registrations in the same market segment. Failing to conduct this verification carries the risk of having the application rejected or facing future legal disputes.

Wrong classification choice

Another common registration error is the incorrect selection of the product or service class when registering trademarks. The classification system used, based on the Nice Classification, divides goods and services into specific categories.
A wrong choice could limit protection or make the registration irrelevant. For example, selecting a class that does not directly apply to the company’s activity may result in the trademark not being protected in the intended markets. Therefore, it is essential to carefully analyze the available classes and choose the ones that best match the business needs. Ultimately, this study prevents future issues related to the scope of protection.

Incomplete or incorrect documentation

The submission of incomplete or incorrect documentation is one of the main registration errors, often leading to the rejection of the application. Incorrectly filled forms, missing signatures, or required attachments can result in the denial of the registration.


Thus, the lack of a properly signed power of attorney or the omission of essential information in the form can significantly delay the process. To avoid these issues, it is recommended to follow the guidance provided by an official Industrial Property Agent. They will assist in verifying all documents before submission. This specialized support will increase the chances of success and, consequently, reduce potential costs related to corrections.

Failure to meet deadlines

In the registration process, there are legal deadlines that must be met, both in the initial submission and in subsequent stages, such as oppositions or renewals. Missing a deadline can mean losing the right or having to restart the process.
For example, failing to respond to an opposition within the stipulated period may result in the application being denied. To avoid such situations, it is crucial to maintain a detailed schedule of all important dates and use alerts or reminders to ensure compliance with each stage within the established deadline.

Lack of process monitoring

After submission, it is essential to monitor the status of the registration application. Failure to follow up can lead to missing important notifications or opportunities to respond to potential oppositions.

At any time, there may be a need to provide additional information or correct details to avoid rejection. To prevent any failures in this follow-up, it is advisable to consult a professional, such as an Official Industrial Property Agent. They can monitor and analyze the status of the application, promptly responding to any notifications or requests within the prescribed deadlines. This is a crucial phase to ensure the success of the registration.

Non-renewal of registration

Registrations have validity periods. In the case of trademarks, for example, they must be renewed periodically to maintain active protection.

Registered trademarks have an initial validity of 10 years and can be renewed indefinitely. Therefore, failure to renew results in the expiration of the registration, allowing third parties to claim rights.

To avoid expiration, it is important to maintain a reminder system, for example. It is also advisable to start the renewal process in advance. This way, you ensure the continuity of your trademark’s legal protection.

In summary, avoiding registration errors is crucial to ensuring the protection of your creations and maximizing their benefits. Understanding all legal requirements, conducting detailed research, and rigorously monitoring each step of the process are essential practices. Additionally, consulting reliable sources, such as the information provided by an Official Industrial Property Agent, is key to making informed decisions. This guidance will be critical in ensuring that all formalities are properly fulfilled, preventing unnecessary delays or rejections.

Care and investment in avoiding registration errors result in the effective protection of creations, ensuring exclusivity, legal security, and competitive advantages. Therefore, investing time and resources in this process is a strategic step to ensure the success and longevity of your rights.
