An Introduction into Patents

with Nereda example

current version of 10 January 2025

1 Introduction

1.1 To the audience

This reader presents an introduction on the use of know-how and intellectual properties (IP) and its benefits for students in science, engineering, medical and business courses. The basic concepts and definitions of IP will be treated and also their use and purpose will be described.

The different topics of IP are explained with an example relevant to your background.

Those interested will find additional information in the appendix links by following the links.

1.2 Every day IP

Chances are that you are using products or services appropriated by a variety of intellectual property rights (IPR) on a daily basis, eg. brands, designs, patents, copyrights.

Many of the products that you will buy or use daily are from a certain brand. Such a brand makes you recognize the product and the manufacturer. For example the brand Coca-Cola for cola. On the other hand manufacturers and organisations use their brands to market their products and services.

Next to brands, organisations have their tradenames registered at the Chamber of Commerce.

The book you are reading or the music you are listening to are works made by an author or musician. These makers would like to be rewarded for the efforts put into the making of their work. You are therefore not allowed to copy this work without their permission since it is copyrighted.

In the development and production of bicycles and cars there are many proprietary technologies. Manufacturers of these product would like to earn back their investments in research and development by using patents.

When you are already developing products yourself now or in the future and when involved as entrepreneur or manager you will have to work with different kinds of IP. As a student it is therefore useful to acquire sufficient knowledge of IP for your future career. Even during studies you it can be worthwhile to use them for many reasons, for example for design assignments.

1.3 Why do IP rights exist?

Several hundred years ago the use of intellectual property rights was hardly known. At the beginning of the book printing technology it became possible to copy and disseminate works of literature far more easily. From that moment authors and publishers started to feel the need to appropriate the rights for the production and distribution of these works. With new technologies during the Industrial Revolution mass production in large quantities became feasible for products and devices. This gave rise to a growing interest by manufacturing companies to appropriate trademarks, logos and patents for their products and inventions.

The modern patent in Venice

During the fifteenth century, Venice was a rich and flourishing city. One of the reasons for this prosperity was the stained glass produced on the island of Murano.

This was a rare and expensive product that became an important economical asset for the city.

However, the formula for making coloured glass was known only to a few people: the glassmakers of Murano.

The Senate of Venice began to worry about the possibility that the glassmakers might die or flee to other countries, thus losing this precious secret.

To avoid such hypothesis, Venice offered the glassmakers to train some apprentices sent by the city. However, the glassmakers refused because accepting the offer would have meant that they loose their monopoly and create potential competitors.

Understanding Murano’s concern, Venice offered, in exchange for the secret, an exclusive right for a limited time to guarantee the glassmakers monopoly. The document granting this right was called a “patent”, from the Latin verb “patere”, meaning to make known.

Thanks to this, the craftsmen accepted the offer and Venice managed to keep the secret, so that we can still enjoy the beautiful coloured glass of Murano today.

In 1474, Venice published the first patent statue in history, to regulate the matter. See figure 1.

Figure 1: The Venetian Patent Statute, enacted by the Senate of Venice in 1474, is widely accepted to be the basis for the earliest patent system in the world.

The general concept behind the use of intellectual property rights is that the creator or manufacturer can apply for a temporary exclusive right hence appropriating their (often intangible) assets and stopping competitors. By doing so the IP owner acquires the possibility to exploit the production of these assets which are otherwise easily copied or manufactured by competitors. So, on the one hand intellectual property rights incentivize persons and innovators who invested both time and money to develop a new product. While on the other hand competitors cannot copy the product and sell it at a cheaper prices without making such investments.

Consumers of those products which have been appropriated with intellectual property rights may have to pay a higher price. Without these intellectual property rights competitors would have been able to sell the products at a lower price. For society at large the introduction of IPR is not only to have all products available at the lowest prices, but to have access to new products and innovations. While using IPR innovative companies are temporarily in a position to charge higher prices thus enabling a return on (earlier made) investments. This is shown in figure 2.

1.4 Well known IP

Companies, entrepreneurs, authors, engineers, developers, scientists and inventors can use a variety of IPRs like copyrights, trademarks, patents, trade names, logos, designs, databases, plant breeders, integrated circuit layout and trade secrets.

Some of the well known IP rights are:

Copyright

Will give the creator (author) at the end of the creation automatically global protection for original works like text, music and images. Copyrights limit free distribution of the work.

Trademarks

After registration, the trademark owner receives the exclusive right to use the trademark for certain goods and services. A trademark right can be used to take action against competitors who want to exploit the same or similar trademark in the same market.

Patents

After the application, registration and examination of a patent, others can be excluded from the commercial exploitation of the patented invention.

Tradenames

Trade and company names are used to make a company known to customers in the market and ensure a reputation and thus customer loyalty. Another company may not cause confusion with its trade name by using a trade name that is too similar to a previously registered trade name.

Designs

After registration, the design holder receives the exclusive right to use the design. A design right can be used to take legal action against competitors who wish to exploit a similar design.

1.5 Frequently used IP for innovations

This document will not describe the legal aspects of IP. See the links to several articles of different laws in Parts of Patent law. We will describe how to use IP, and more specifically for innovations. An overview of the importance of the different IP rights for innovations can be seen in the following table.

From: Scotchmer (2004) Table 9.1, page 260.

Source: Cohen, Nelson, and Walsh (2000), table 1. Note: Each number is a mean response, representing the percentage of product innovations in the row category for which the type of protection in the column is deemed “effective”. The response categories are <10%, 10%–40%, 41%–60%, 61%–90%, >90%.

In general we can see that secrecy (including what we call know-how) is one of the most frequently used appropriability mechanisms. At the same time patents are important in the sectors drugs and medical equipment.

Other IPRs (for example trademarks or designs) are less frequently used for innovations, but are of course very important for sales and marketing.

1.6 An example using patents and IP rights for technology transfer

In this section we introduce the example which will be elaborated in next chapters, which elaborates the commercial use of an academic patent in one of the Dutch topsectors of industry. Research took place at the University of Technology at Delft in the Netherlands by professor Mark van Loosdrecht and dr. Merle de Kreuk in the mid nineties.

Based upon their research a novel methodolology for sewage water treatment using more efficient sludge granules was developed. This methodology has been patented by the university. These granules show a better performance in waste water treatment plants due to improved settling properties while at the same time removing nitrogen and phosphorous. Therefore this technology enables a fast, simple and compact treatment with less energy consumption. In the end the water quality of the effluent is better leading to less pollution problems for the environment.

The subsequent steps of developing and piloting this technology on site has been executed by engineering company Royal Haskoning DHV together with the university. Funding for this work in research and development and scaling has been provided by several organisations eg. the Netherlands Entreprise Agency (RVO). After piloting at the waste water treatment plants Veluwe, Rijn and Ijssel and Rijnland, the technology has been implemented by contractors in other plants worldwide. In 2020 the Nereda technology has been a nominated as a breakthrough technology in this sector. As such the case of Nereda shows an excellent example of research commercialisation enabled in a public private partnership.

See for more information about the Nereda technology Nereda case.

Figure 3: Nereda process cycle

The priority patent for this technology entitled ‘Method of the treatment of waste water’ can be found in NL1021466C2. During the priority year the application has been continued as WO2004/024638A1 and subsequently as EP1542932B1. The first patent is owned by the University of Technology Delft and in 2005 the patent has been assigned to engineering company DHV (later Royal Haskoning DHV, or RHDHV). Meanwhile the title has changed into ‘Method of the treatment of waste water with sludge granules’. These patent application procedures will be elaborated and used as example in this case on academic patents (see Strategy Nereda).

This patent application is used as the example for the explanation of patents. The application can be seen in WO 2004/024638 A
