Complete guide to patent types
There are three common types of patents that are useful for protecting innovative products and inventions.
The different patent categories can be more or less suitable depending on three key factors:
- the characteristics of your invention
- target market
- business model to monetize the patent
Design protection safeguards the aesthetic appearance of a product — what can be perceived at a glance. It is suitable for products that aim to stand out through their visual look.
It is a weak form of protection. In theory, it covers minor changes in products that cannot qualify for a patent due to lack of novelty. Around 90% of inventors choose it by mistake.
Useful for protecting innovative products that, by introducing non-obvious changes, provide real added value to users. It is the most serious and rigorous protection method available.
Patent alternatives to protect an invention

Source: Own elaboration based on public data from the Spanish Patent and Trademark Office.
“It’s true that the invention patent is no longer the type of patent most commonly chosen by inventors. In my view, this phenomenon is due to the lack of rigor with which Utility Models are granted in Spain, and to the significant lack of awareness among inventors about the alternative patent options available.”
Erick Remedios Muiños

Types of international and national patents
National patents are those granted by the official patent and trademark office of a specific country, following the corresponding examination and payment of fees.
Las patentes mundiales no existen. No existe un tipo de patente que al ser concedida proteja el producto en todo el mundo.
Aunque no existe la clasificación de patente internacional, es cierto que si una patente ha sido examinada y aprobada en varios países, puede denominarse «internacional»
Common questions about patent types
The invention patent in Europe, or utility patent in the United States, represents the best method for protecting a product.
The protection and exclusivity granted by a patent to the inventor of a product should be a sufficient legal instrument to defend authorship.
To be realistic, when a product is truly good and succeeds in the market, patents do get copied. These are the situations that reveal the difference between patents that are rigorously drafted and protected, and those that are not.
Absolutely not. You do not need a specific type of patent to market an innovative product. Patenting a product is optional.
Unlike Utility Models and Industrial Designs, patents are examined by a specialist at the patent office. Successfully passing this process is complex. This procedure is precisely what guarantees the authenticity and rigor of a patent.
Patenting is not our business

Analysis of the Idea or Invention
If you want to assess the feasibility of an invention and its business potential, we will conduct an analysis of product sales or similar inventions on major platforms, both in Europe and in the United States.
We can also assess the technical feasibility of an invention. We will determine the electronic components and forms that would allow achieving the functions and improvements you propose. This way, we can determine if an invention is viable.
The team of engineers and business and marketing personnel will work together on designing the preliminary strategy to protect or patent the invention in question.
50% of the inventors working with Let's Prototype are individuals or small businesses. For this reason, we always work with fully closed budgets in all cases. It is essential for us that clients have a complete understanding of the economic impact of the invention's development and patent strategy.

Background Study of an Invention
How to know if an invention already exists? The truth is that, through a background study of inventions, it can be determined whether the invention is registered or patented, both in the inventor's country of origin and in other countries. But, even if an invention is not patented, it may still exist. It is key to combine the search for background of an invention in patent records but also on commercial platforms.
The identification of invention patents that could affect the possibility of applying for a patent is carried out through three fundamental methods:
Method A – Semantic study.
Method B – International Patent Classification Codes.
Method C – Study of headlines

Patent Application Documentation
Taking as reference the analysis of our engineering team, as well as the main conclusions of the manufacturing process of the your working prototype, we will write the necessary documentation to formally file your patent application. It is relevant not to skip any steps. If there is no working prototype, we can hardly obtain an effective patent.
In some cases, due to the characteristics of the invention and its commercial potential, the patent application is filed after the completion of the basic engineering project. In this process, the instruction manual for manufacturing the prototype is determined, and the systems, designs, components, and any element relevant to the patent documentation process are identified.
In the case of Industrial Design applications, we can prepare, under the guidance of a licensed attorney in the United States and experienced in Europe, the necessary documentation, blueprints, and sketches."
In the case of Utility Models, although we discourage them in many cases, we can also help you prepare the memorandum. Only if we see it appropriate due to the commercial strategy and characteristics of the invention
Presentation and follow-up
The hard part will already be done; in this section, we will take care of the administrative procedures to file your patent. We will consider every detail to make it comprehensive yet precise, so it can truly meet your expectations and business needs.
If necessary, our team will respond to any inquiries that the corresponding Patent and Trademark Office may make.
The time to bring your ideas to life is now. We accompany you throughout the entire process: from idea to product.
