The intellectual property rights
I think that is what they are talking about here and don't think you actually need to mention the word "products" at all. Why translate it word for word?
Is this some sort of licence agreement?
See below (from www.intellectual-property.gov.uk/std/faq/question1.htm
What is intellectual property or IP?
Intellectual property, often known as IP, allows people to own their creativity and innovation in the same way that they can own physical property. The owner of IP can control and be rewarded for its use, and this encourages further innovation and creativity to the benefit of us all.
In some cases IP gives rise to protection for ideas but in other areas there will have to be more elaboration of an idea before protection can arise. It will often not be possible to protect IP and gain IP rights (or IPRs) unless they have been applied for and granted, but some IP protection such as copyright arises automatically, without any registration, as soon as there is a record in some form of what has been created.
The four main types of IP are:
patents for inventions - new and improved products and processes that are capable of industrial application
trade marks for brand identity - of goods and services allowing distinctions to be made between different traders
designs for product appearance - of the whole or a part of a product resulting from the features of, in particular, the lines, contours, colours, shape, texture or materials of the product itself or its ornamentation;
copyright for material - literary and artistic material, music, films, sound recordings and broadcasts, including software and multimedia
However, IP is much broader than this extending to trade secrets, plant varieties, geographical indications, performers rights and so on. To understand exactly what can be protected by IP, you will need to check the four main areas of copyright, designs, patents and trade marks as well as other IP. Often, more than one type of IP may apply to the same creation.

This is something about contracts in relation to IP from the same website:
Transactions about IP such as licence agreements and agreements to transfer ownership will involve the making of contractual agreements. In many cases, but not always, a contractual agreement will be able to override any provisions in IP law that might conflict with what is to be agreed. A contractual agreement is usually particularly important where you have commissioned someone else to create something protected by IP since, without a contract, you may not know whether you are licensed to use the IP.
Even where IP is not to be licensed or ownership transferred, there may be situations where a contractual agreement about IP is important, such as:
An agreement between a person investing in the development of IP who will not necessarily own any IP that is created, but who may become entitled to some form of payment at some point in the future.
An agreement between a creator of IP and a potential partner in its exploitation to discuss what might be possible under a confidentiality agreement.
An agreement between right holders and a collective licensing body over administration of some of the IP rights.
In every case, general provisions in law about what contractual terms are acceptable need to be considered carefully as well as the nature of the IP that is the subject of the contract. In particular, competition law and company law may be relevant.
