The issue of most concern to everyone who asks us about the possible protection of an invention is how much it costs to patent.

In these times it is a logical question, but from our point of view what really should be of their concern is to know whether their invention is patentable or not. We already discussed this subject on a previous post: “Is my invention patentable?”

In the following lines, we intend to throw light on the costs involved in getting a patent in Spain, once the invention is valued and decided that is worth a patent for its protection.

How much does it cost to patent in Spain. Application

First of all, is important to remember that patents in Spain are processed by the SPTO, Spanish Patent and Trademark Office.

Developing a patent application in the proper way is a quite tedious task which involves a specific knowledge of the matter and experience, especially in the writing of the specification of the invention usually attached to the application.

The official rate of a patent application in Spain today is 74,92 €. If the patent application in Spain is made claiming international priority from another country, the fee of foreign priority of 19,85€ is needed to be added.

In case of going to an Industrial Property agency, which is highly recommended, professional fees must be added to this amount, which range between 900 and 3000€, depending on the complexity of the case and the rate of each professional.

These costs include: the development of the specification by high qualified technicians and, if necessary, planes or figures; talso he correct filing of the application and its active monitoring.

It is very important to attach to the patent specification a set of drawings in order to complement the description pf the invention and facilitate its understanding. The drawings are presented in a separate section of the description and must meet certain specifications and formats.

After the granting, annual maintenance fees must be paid for the patent to remain in force during 20 years. If the payment of this annuity is not realized, the patent is lost, passes into public domain and may be used and exploited by anyone.

Considering that the process of a patent in Spain implies a long period, the first 2 annuities for the maintenance are included in the application fee. Therefore, maintenance fees starts to be paid from the third year retroactively from the granting. For example: if a patent is granted 4 years after the application, the amount for the maintenance of the 4th and 3rd annuity after the granting shall be paid.

It should be considered that the older is a patent the higher is its maintenance fee, as we can see in the following column of official fees (in euros) updated by date of January 2015. To these amounts professional fees must be added.

Before concluding is interesting to know that after the approval of the new Spanish Patent Law, which will came into force on 1 April 2017, the granting procedure tends to be uniform with the rest of patent offices. From that date will be required to pass an examination to all patents. Besides the new law aims to encourage the protection of innovation by SMEs and entrepreneurs by reducing the cost of official rates.

As we have seen, registering a patent in Spain involves complex administrative process which require long time and specific technical knowledge. For this reason, despite being more expensive, hiring an expert team and having their advice is, in any case, a very interesting option.
