You can use Brands in Privately Commissioned Ketubot - but not ones in the Store!
Running a business always presents interesting intellectual problems. Here is today's.
So, creating Ketubot by hand creates some interesting Intellectual Property problems.
For example, we recently got a request for an Apple computer themed Ketubah!
As Mac fanatics, we loved this! I almost want one myself :)
Here's the problem: the Apple logo is a trademark owned by Apple. We can't use it publicly without getting Apple's permission and paying them a lot of money.
Guessing Steve Jobs' response, I wouldn't be too optimistic.
That said, here's an interesting compromise: perhaps we can do it privately? If it we create a custom piece of art, that isn't displayed or used publicly in any way, do we need to get Apple's permission?
Maybe, maybe not; but it's ambiguous enough where perhaps we could take the risk! Lets do it!
