Changes to UK copyright law will soon mean that you may need to take out a license to photograph classic designer objects even if you own them. That's the result of the Enterprise and Regulatory Reform Act 2013, which extends the copyright of artistic objects like designer chairs from 25 years after they were first marketed to 70 years after the creator's death. In most cases, that will be well over a hundred years after the object was designed. During that period, taking a photo of the item will often require a license from the copyright owner regardless of who owns the particular object in question.
It is already law in UK, they just discuss the day it will start working.
