Imagine if patents had been eliminated. They would have died once a big company like 3M got a sample back to their lab. This company exists because they were able to patent their invention. People say that patents are bad because everything relies on previous efforts. Well, they didn't invent silicon rubber. They didn't invent the volatile compound that allows their rubber to cure overnight. But they did invent a new…
One of the major reasons that people oppose software patents specifically, rather than all patents: software already has copyright, while physical objects don't. Also, even if a company like 3M did start making the stuff (and patents or no patents, they easily could by finding a different variation), do you really think that would put Sugru out of business, given the kind of community they've managed to build?
Absolutely. If not put them out of business, it would completely cripple their future prospects. 3M has MASSIVE distribution. When Suguru finally gets to the store in their town, why would Joe and Jane buy from some brand they've never heard of when they've been using the 3M equivalent for a year and it's been working great?
