(IMPORTANT) Patent company going against h5p use of a patent

[joeroot411]

I work as a consultant in a company which uses h5p with moodle. I heard that some patent portfolio company (could be patent troll) is asking for licensing fees to use one of patents in their portfolio. My client company is using h5p interactive video AS IT IS without any modification so basically patent company is saying h5p methods are violating their patents. As per them, Patent US 8,750,843 is directed to a call-to-action lockout while using media content on mobile devices. Your application (h5p code) uses all elements of independent claim 1 by providing enhanced video for courses played via their mobile device. Activities are triggered at specified times within the video.

Then they showed attached screenshot as violation example.

In summary, on any mobile device, we can not use interactive video features otherwise we will be violating their patents as per their claims.

If they succeed in proving this and come after moodle-h5p users or h5p project itself, it could be a problem. They are NPE(non

performing entity) meaning not another software or elearning company but pretty much use patents to make money.

Any idea if these claims are valid? What should be the next steps?
