The intellectual property sector protects innovation developed in highly specialized fields. It makes sense that, when entrusting their language services, their partner should also be able to protect the very essence of their service: innovation, specialization and confidentiality. This is where Montero IP comes in, offering a reliable solution based on knowledge that only years of experience can guarantee, but in which processes, technology and methodology are constantly evolving.

Our translators are not only native speakers of the target language, they are also specialized in the subjects they translate, often having related technical degrees. This means that in addition to being well-versed in patent-specific technical language and vocabulary, they have extensive, up-to-date knowledge of their area of expertise. This ensures legal, technical and scientific terminology are accurately used by the same linguist.

As John Ruskin said “Quality is never an accident. It is always the result of intelligent effort.” And this is exactly our approach. We meticulously select the professional assigned to each of the steps of our work flow in order to guarantee the highest quality that their talent can provide. In tandem, we apply the latest technology to each of these steps so as to maximize their potential for our customers.
Quality assurance is often exclusively related to human contributions in the translation process. However, while it is true that this contribution is essential, it is now a reality that new technologies in the field represent a necessary and vital contribution to ensure the highest quality, from initial request through to timely delivery.

We invest in market-leading software to assist our team in their day-to-day work. Innovation and technology have become our best allies in ensuring that our customers can meet short filing deadlines while delivering top-quality translations that do not compromise their global efforts and protect their intellectual property correctly. Montero is committed to innovative systems that guarantee a technology driven workflow from the receipt of the project to the final delivery and validation from the customer.
