I think we're dancing around technologies that may have patents in the same ways that all developers do: basically, we avoid famously patented tech and try to use well-known libraries as much as possible (safety in numbers, at the cost of chilling some innovation), but hoping that we don't pass too close to any submarine patents. The worrying one I've seen recently has been 3M and SIP. It took quite a few rounds on the SIP 3 message boards before (as I understand it) we were assured that no patents held by 3M would necessarily be infringed by implementing SIP 3. 3M accused Envisionware but I don't remember the detail or know the current situation. I probably ask more questions about this than many, even though I work for a software developer and am fortunate to work in a country where mathematics - which includes software - is explicitly excluded from patents.
