My colleagues are in the design department of a given product, and when asked to add that information to the e-mail signature, they have written:
ProductName's Design
I'm objecting that the usage of the Saxon genitive there is incorrect, because the product is neither a person or animal owning anything, and Design in this context is not even a property of the product (Maybe I would admit the Saxon genitive in a context like "I think ProductName's design is not fail-safe"), but an activity.
Am I right? ^_^
update:
After reading the answers and the comments, I think the issue has been clarified a little bit. In this case ProductName is acting as an adjective qualifying Design [Department], so that's the actual reason for not using the genitive case (rather than the product being a "weak entity" unable to possess things, that is merely an stylistic rule of thumb).
