This is an extended question to my previous question: Leading customers to use cheaper solution invented for another domain instead of expensive patented solution. Infringement?
As far as I know, if one component is different from the registered patent, it is not an infringement.
For example, in claim 1 of the following patent, authors are claiming a patent on a markerless system with stereo vision, which I understood that if I use a marker or 3 cameras instead of stereo vision, it is not infringing their patent whereas others say just changing one or few parts of the patent could be still patent infringement.
I understand that the interpretation of infringement could be different under different situations but I was wondering what you guys think.
I am taking it to a patent attorney next week after studying the patent law myself a little bit. I will share the result here too.
