I agree, its not the same case. The problem might be in 15 years from now, your algorithm might just become a very natural way to solve that specific problem and at that point how your company plays this out matters. My guess is the companies that are in the business of making, creating, producing and then selling software themselves, will be ok with it. These trolls like Lodsys try to neither produce nor create. A very important rule for the any type of patent should enforce "active" product in use/development. Sadly, it might never happen.
