Q: Understanding the score of a specific patent

https://www.google.com/patents/US9383820

Hello, I want to understand the scope of this patent. From what I saw they are patenting custom vibration patterns in relation to creation of alerts. Though, I do not understand if they are patenting the custom vibration patterns or the custom vibration patterns in relation to alerts. What is the scope of their invention cause I see creating custom patterns by touching the screen as obvious.

I want to create a custom massager application. The application will allow the user to input a custom pattern by touching the screen with the approach mentioned in the above patent (without visuals) and after he is done the pattern will be stored and used to massage the user. Will that patent prevent me from developing my application? I do not want to get sued by a large corporation. I am planning on selling my application if that matters.

Thanks.

A: The scope of patent claims and their validity are really tough issues that warrant you retaining a patent specialist attorney and possibly challenging the referenced patent before the PTO.
