Valuation of an intellectual property not only depends on the intrinsic value and the commercialization of the invention or the brand, but also the market in which the intellectual property is commercialized, as well as the general macroeconomic conditions. Thus, valuation requires a broad understanding of intellectual properties, business, markets and finance.Proust Patent provides academic-grade valuations for both market value judgment purposes and accounting purposes.Market valuation of intellectual property assets have indispensable use in business decisions such as new investments, market strategies, mergers & acquisitions.In accounting, intellectual properties are recorded as intangible assets and the valuation rules are governed by IFRS (or another government body such as GAAP, which your company's accounting system follows.) Accounting valuations may or may not reflect current market valuations from which business decisions arise; regardless, it is a benchmark valuation and it is of constant use in company balance sheets.Valuations services are provided for portfolios of or individual intellectual properties for a variety of customers:
- Corporations
- Startups & Entrepreneurs

One of our defining features is that we understand the businesses of our clients. With a clear communication and in total understanding with the clients, we lay out the groundwork for strategical decision making in IP related decisions.A good IP strategy requires a deep understanding of the following areas:
- Business & Business Knowledge
The commercialization of an intellectual property inherently depends on how the current (or conceived) business operates. The revenue model of the business and how the new invention or trademark protects or extends it are key foundations.
- Competition & Market Knowledge
IP strategy is not independent of the competition in the market and the current segmentation of the market under which the business operates. With an understanding of the market, IP strategy should be in sync with the general strategy of the business.
- Intellectual Property Rights Knowledge
Another pillar of a good IP strategy is a good IP domain knowledge. Only with knowing the perks & details of your rights, how they protect you, time requirements, costs and how to get to the protection on top of your head will enable you to consider your IP strategy options in full.

Translation Process

to assure Quality

Overview of Our Process

The more individual patents applied in multiple countries, the more incentivized overall innovation is. Translation of patent documents is the barrier in reaching large-scale protection.We understand that the quality of the translation matters not only in the application/validation process but also in the future of a patent's life. A patent is meant to protect the rights of the owner in its full life time and its strength originates from how strong the text will stand in a possible case of an enforcement or litigation. A clear, concise and exact representation of an original patent document is critical in the practical protection of the innovation in a foreign country.We consider the quality of the translation as a key to form a better IP rights environment and a better innovation environment for all. That is why we employ a double quality assurance method on each of our patent translations.

Translation Process

to assure Quality

1) High Quality Translation: Patent-Oriented

Our process starts by translation of the original patent document by patent-specialized translators. At this stage, the translators are experts of their language and highly experienced in patent translations. The translators we work with are the best available translators around and we compensate our translators' efforts very well with respect to the market.

2) Quality Assurance 1: Technical and Legal

We assign a Patent Attorney with a relevant technical background to each of the translations. This step has two main goals. First, as patent documents are technical and legal documents, and the terminology may have nuances, our technical patent attorneys find the best terminological representations. Second, as our patent attorneys are experienced in enforcement and litigation, they can chose the best formulation of translation. At this stage, our patent attorneys work very thoroughly, going over the translation word by word.

3) Quality Assurance 2: Language

At this stage, we have the translation controlled one more time by a different translator. The controller performs a formal check, a language check and an overall check of the translations with a fresh eye.

4) Finalize and Apply

The proposed change logs in the second quality assurance stage are forwarded back to the assigned Patent Attorney. The last edits and decision making are made by the Patent Attorney. And the translation is finally ready for the application or validation process.
