Hi! I was thinking to build a SaaS platform to implement a SEO strategy in client's sites. The strategy is already used by several sites, so it isn't totally unknown. The thing is, I spotted a direct competitor, that is doing the same thing. I investigate it a little bit and he has patent this "SEO strategy" a couple of years ago (2014). I don't really now how "legal" is to patent a SEO strategy or if am could build something similar as long as the system is not exactly the same as the one from my competitor. I know that my question is not very precise, and I will consult with an attorney, but I wanted to know if anyone here had some experiences about this issue. Thanks in advance!
