However, providing third parties with a constructive notice, alerting them of the existence of your rights, does have its advantages. In this simple guide to marking your IP rights, we take a look at some of the advantages and pitfalls in relation to product marking, and list the correct ways to mark your products, services and creations.
The term ‘patent’ or ‘design’ without identification of the patent or design number is insufficient to establish that an alleged infringer should be considered to be aware of the existence of the right.
There is no symbol that can be applied to a product to denote that it is patented or has a registered design. Instead, products can be directly marked (e.g. stamping, engraving, labelling) with either:
The UKIPO provides this example.
Caution must be exercised to ensure that the information is kept up-to-date and any change in the status of the patent or design is accurately reflected. Removing the need to mark the patent or registered design numbers directly on the product by using an internet link reduces the burdens and costs for businesses and individuals, and improves transparency for the public by providing easier access to current patent and registered design information in relation to a product.
Marking:
The ® symbol can be used when a trade mark is registered. Conventionally, it’s placed on the right-hand side of the trade mark, superscripted, in a smaller type size than the mark itself.
The abbreviation RTM can also be used, but in practice rarely is, to show that the mark has been registered.
The ™ symbol can be used if the trade mark has not been registered to show that the mark is being used as a trade mark. In the UK, the use of ™ has no legal meaning. The ™ symbol is conventionally placed on the right-hand side of the trade mark, superscripted, in a smaller type size that the mark itself.
As trade mark registrations are protected by territory, we recommend using the ™ symbol on products or their packaging, if the product may be sold in territories where the trade mark is not registered. This avoids the need to have multiple packaging designs for different territories. It is also advisable to use the ™ symbol on the internet, particularly if you operate a website from a gTLD, as this is a means of advertising globally.
By using an asterisk (*) or similar symbol to direct the consumer to a footnote indicating that the mark is registered or “is a trade mark [service mark] of [company name].”
Copyright is an automatic right. You do not need to apply to register it in the United Kingdom.
You automatically get copyright protection when you create, amongst other things:
Whether or not you mark your work with a symbol denoting the existence of copyright in the work, the level of protection you have against infringement is not affected. A benefit of using the copyright symbol is that it provides a reminder that copyright exists in a work. It also identifies the copyright owner and the year of publication, so that people know who to contact if they want to request permission to use the work.
© is the normal copyright symbol and can be applied to most types of work. The ‘P’ copyright symbol is the internationally recognised symbol of protection in a sound recording. It is often found on CDs or on record sleeves.
The full copyright notice consists of three elements in the following order:
You can incorrectly display the symbols when they are used in combination. Never combine the two notices, as this may invalidate them — place both separately, on two different lines.
