I disagree. I feel that patents should exist to help companies recoup the cost of expensive R&D. Designing a window manager of this kind doesn't fall under that umbrella. Any reasonably competent software designer could come up with UX like this without a large time investment. Different companies should be able to iterate and refine these kinds of designs. This only has the effect of reducing the size of the software economy and does not provide the intended benefit of helping anyone recoup expensive development costs.
