The Official Google Blog has a post on the increasingly generic uses of the word ‘google.’ (This is something I have commented on before here and here).

 

Q: What do zippers, baby oil, brassieres and trampolines have in common?

A: No, the answer isn’t that they’re all part of the setup for a highly inappropriate joke. In fact, the above list (along with thermos, cellophane, escalator, elevator, dry ice and many more) are all words that fell victim to those products’ very success and, as they became more and more popular, slipped from trademarked status into common usage.

Will “Google” manage to avoid this fate? …

A trademark is a word, name, symbol or device that identifies a particular company’s products or services. Google is a trademark identifying Google Inc. and our search technology and services. While we’re pleased that so many people think of us when they think of searching the web, let’s face it, we do have a brand to protect, so we’d like to make clear that you should please only use “Google” when you’re actually referring to Google Inc. and our services.

Here are some hopefully helpful examples.

Usage: ‘Google’ as noun referring to, well, us.
Example: “I just love Google, they’re soooo cute and cuddly and adorable and awesome!”
Our lawyers say: Good. Very, very good. There’s no question here that you’re referring to Google Inc. as a company. Use it widely, and hey, tell a friend.

Usage: ‘Google’ as verb referring to searching for information on, um, Google.
Example: “I googled him on the well-known website Google.com and he seems pretty interesting.”
Our lawyers say: Well, we’re happy at least that it’s clear you mean searching on Google.com. As our friends at Merriam-Webster note, to “Google” means “to use the Google search engine to find information about (as a person) on the World Wide Web.”

Usage: ‘Google’ as verb referring to searching for information via any conduit other than Google.
Example: “I googled him on Yahoo and he seems pretty interesting.”
Our lawyers say: Bad. Very, very bad. You can only “Google” on the Google search engine. If you absolutely must use one of our competitors, please feel free to “search” on Yahoo or any other search engine.

Thanks for your attention, and we look forward to serving your search-related information needs again soon.

So it is all about trademarks. Yes, Google has done so badly because of the common usage of its word.

By the way, here is how you “google ‘Joshua Gans’ on Yahoo.” What IP thing is that violating?
