I agree. Now, if Netflix patented their envelopes, etc, and Blockbuster infringed on that patent, they may have a case.
But, how many companies out there use return postage, etc?
Oh, and I think the Burger King in the next town over has a play yard thing too. And these are fairly old stores.
Well, there's 'differences' to the ways those things can be organized to get around the patents... I'd have sworn McD's had one on that... well anyway.
