A company called ThoughtOut has been sent a Cease & Decist order from Apple to stop selling or rename their iPod stand called The iPed
Jackwhispers has brought you similar stories in the past. If you want to release Apple products - development guidelines are pretty clear. I don't think they are executed with the same fairness though. I believe MacMice/DVForge has broken the naming guideline several times and I also believe that the Sonnet PodFreq breaks the naming guideline ( not to mention, possibly infringing on that DLO patent ).
Apple rules for product naming:
The Mac Trademark
1. You may not use the Mac trademark standing alone except to denote or refer to the Apple Macintosh product line.
2. You may use "Mac" in your product name, company name, trade name, or service name provided your name satisfies the following criteria:
a. Your product is not a computer, computer system, or operating system software.
b. Your product is Mac compatible or the third party business is associated with Mac based computers.
c. "Mac" is used in combination with another non-generic word.
Acceptable: MacVenus MacCharlie
Not acceptable: MacCharleston MacSales
d. "Mac" does not appear more prominently than the rest of the name in size, color, or typeface.
e. Your name does not suggest a false association with Apple.
f. Your name is not confusingly similar to any trademark owned or used by Apple.
g. You acknowledge that Apple is the sole owner of the "Mac" trademark and that you will not interfere with Apple's use or registration of "Mac" alone or in combination with other words.
Very similar rules for naming with the term Apple also exist
I have always loved the other bad example listed on this page:
Not acceptable: Jackintosh
