A: Short answer is that I do not know.

Good news is that there are several free online tools to do patent searching. I gave a talk on these tools

October 2016 presentation at the RTP Frontier as part of the lecture series for Triangle TechBreakfast. Teaches entrepreneurs on how to perform searches for relevant patent applications and issued patents.

Here is a link to my slide set for that talk and the slides will give you pointers on how to use these tools. When you find anything that seems particularly relevant, it is wise to have a patent attorney may a final call on whether that patent is a impediment to your freedom to operate in the manner you want. It is possible for example, that the patent you find may be expired or lapsed as it was not renewed by paying the required maintenance fee. It could be that the negotiations with the patent examiner to get the claims issued permanently narrowed them.

I hope this helps.
