Remember that except for bragging rights a patent is worth nothing unless you can afford the big bucks to defend it. There are no "patent police", it's up to you to bring a civil suit if you think it's being infringed on. I feel like outside of biotech and some materials science, patents are one of the most useless things aspiring entrepreneurs waste their time and money on, and taking a patent case to court is just a massive cost and distraction for a startup I can't think anyone but a lawyer would recommend.
