How trademarks become generic...

A generic trademark (sometimes called a genericised trademark or proprietary eponym) is a brand name that becomes so synonymous with a particular item that it effectively ‘becomes’ that item.

The best examples of generic trademarking (in the UK) are Hoover and Sellotape. Hoover, in particular, is the most generic term for a vacuum cleaner in the United Kingdom. So much so that, when I worked for a high street electronics retailer, customers would come in and ask for a ‘Dyson Hoover’ or ‘LG Hoover’.

This can be both a blessing and a curse. It's nice to think that your brand or product is so synonymous with a particular item that people don't refer to it any other way; however, it can mean losing legal trademarking and protection over that name. 

Sellotape’, owned by a company in Winsford, Cheshire, is a generic term for adhesive tape. ‘Trampoline’ is originally a trademark of the Griswold-Nissen Trampoline and Tumbling Company. Both companies have lost any legal protection against their brand names being used as generic terms for the items they’re associated with. 

Many companies today will seek any means necessary to stop their trademarks and products becoming generic. The biggest of these is Google. 

Google have actively discouraged various publications from referring to web searches as ‘googling’, to avoid their brand becoming a generic trademark. In fact, both the UK’s Oxford English Dictionary and the US’s Websters Dictionary define google (all lower case) as a verb with the meaning ‘to use the Google search engine to obtain information on the Internet.’

Some companies have fallen foul of their own hubris on certain products. The Otis Elevator Company lost both trademarks for ‘elevator’ and ‘escalator’ because they excessively used the terms in their own advertising campaigns. This saw the public use the term whenever they referred to a ‘vertical cable transport machine’ or ‘motor driven staircase’. When Westing House Electric Corporation made their own escalators, the courts and trademark office concluded that, as Otis had used its own trademarks in a generic way, the terms would be subject to genericisation, which allowed Westing House and anyone so inclined to use the names freely.

Generic terms can be country- and even age-based. My daughter, who’s thirteen, turned to me recently and asked for a ‘band-aid’ to cover a blister. I would have asked for a ‘plaster’, a word derived from the company name Elastoplast, which is the biggest seller of adhesive bandages in the UK. My daughter, however, watches a lot of US television and (with my approval) some American YouTube channels; these use the term ‘band-aid’ to describe adhesive bandages.
