I am not a lawyer. I am doing some basic research about laser scanner patents (this is my first time). A laser scanner is a 3D scanner that shines a laser onto an object and uses the information captured to reconstruct the object. The technology has been around for a few decades.
When searching the USPTO site for (TTL/laser AND TTL/scanner) I found 364 patents, many of which are just titled "Laser scanner". Digging deeper into them, it looked like most of them used basically the same concept but with a small tweak that sometimes took me an hour to even find.
I'd like to understand more about this. Does this mean that if I make a minor tweak to the product, it would be non-infringing? If so, what is the process for me to determine that? And if not, then how do I reconcile the existence of so many patents and find out which (if any) applies. And what if our design overlaps with parts of some of the patents but not a single patent?
Thank you for your help
