I will try to explain this generally so as to help with the understanding. Lets say an inventor patented a "folding" sight that sits on top of a barrel and folds with a hinge. I have a new idea that would still be a "folding sight" but would operate differently and not with a hinge, does this seem like something that would cross the lines of infringement?
for another angle at this, someone patents a PC monitor holder with a pivot in a certain spot and clearly identified in a patent. I too want to make a pivoting monitor holder but mine works differently and pivots with different components but ultimately still pivots. Would this be an issue?
To add to this, I have noted that a particular patent holder is not even adhering to their own patent in their designs yet still marking their product as patented. I am confident that there are still elements in the design that are following the patent but was not sure if all elements or claims had to fit?
I guess one of the things confusing me in the patent is not understanding by the description what is actually being patented and what is simply in the drawings for representation. For instance, if there is a flyout and number, does that mean that it is fully described, therefore is part of a patent? IE, multiple claims in one patent?
