The short answer: no, there is no single class for services. Services occupy eleven classes, from 35 to 45, and picking the wrong one is one of the most common reasons a service business ends up with a registration that does not protect what it actually sells.
The assumption that trips people up is that Class 35 is the general services class. It is not. Class 35 is a specific class about advertising, business administration and retail services, and most service businesses do not belong in it.
The eleven service classes
Class 35 — advertising; business management, organisation and administration; office functions. Also retail and wholesale services, recruitment, bookkeeping and market research.
Class 36 — insurance, financial and monetary services, banking, and real estate affairs.
Class 37 — construction, installation, maintenance and repair services.
Class 39 — transport, packaging and storage of goods, and travel arrangement.
Class 40 — treatment of materials, which in practice covers manufacturing, processing and finishing done for other people.
Class 41 — education, training, entertainment, sporting and cultural activities.
Class 42 — scientific and technological services and research; industrial analysis and design; and the design and development of computer hardware and software.
Class 43 — services providing food and drink, and temporary accommodation.
Class 44 — medical and veterinary services, hygienic and beauty care, and agriculture, horticulture and forestry services.
Class 45 — legal services, security services, and personal and social services rendered to meet the needs of individuals.
What Class 35 actually covers, and what it does not
The official heading for Class 35 is: advertising; business management, organization and administration; office functions. Around that heading sit services like retail and wholesale services, personnel recruitment, bookkeeping and accounting, market research and search engine optimisation carried out for sales purposes.
The exclusions are where the real value is, because they are exactly the assumptions people make wrongly:
Financial services and real estate management are
not Class 35. They are
Class 36. A property brokerage does not file in 35.
Transport logistics is
not Class 35. It is
Class 39.
Graphic design and energy auditing are
not Class 35. They are
Class 42.
Legal services and the licensing of intellectual property are
not Class 35. They are
Class 45.
The retail trap
Class 35 covers retail as a service — the act of bringing a range of goods together so that customers can see and buy them. That is what a shop, a marketplace or an e-commerce platform does for third-party products.
It does not protect the goods themselves. If you sell your own branded product, Class 35 protects the shop but leaves the product unprotected. Someone else can register your name for the goods you actually make.
This is the single most expensive mistake in this area, and it is usually made by businesses that think of themselves as sellers rather than as manufacturers. If your brand goes on the product, you need the goods class as well.
Software, apps and SaaS
Software sits in an awkward place because it can be a good or a service depending on how it is delivered.
Software the customer downloads and runs is a good, and belongs in Class 9. Software delivered over the internet as a service, which covers most modern SaaS, is a service and belongs in
Class 42. If a platform also runs a marketplace for other people's goods,
Class 35 may apply on top.
Many software businesses legitimately need more than one of these, and which ones depend on the delivery model rather than on the technology.
When you need more than one class
Classes are not a menu where one has to be right and the others wrong. A restaurant group that also sells packaged sauces is genuinely operating in
Class 43 and in a goods class. A training company that publishes its own books is in
Class 41 and in Class 16.
Each class is filed and examined separately, and each carries its own government fee, so the practical question is not how many classes you could justify but which ones carry real commercial risk if someone else takes them.
The test that works: for each class, ask whether a competitor using your name there would damage you. If the answer is yes, it belongs in the application.
Finding your exact service
The class headings above are a starting point, not the answer. Examination works on the specific description of services, not on the heading, so two businesses that both call themselves consultants can land in different classes depending on what they actually do.
Search your specific activity in the
trademark class finder rather than reasoning from the headings. Where an activity genuinely straddles two classes, that is usually a sign the specification needs drafting carefully rather than a sign that one class is wrong.
