How do Graduate Admissions Committees view an applicant from Industry?
There are several considerations that may make it difficult for you.  Here are a few based on gut instinct:

1) You are an 'outsider' - the traditional route of undergraduate to graduate school often entails nurturing relationships with other academics at your home institution and abroad.  Those relationships help grease the wheels when it comes to letters of support.  But, this can be overcome. Perhaps you already maintain relationships with academic circles.  Failing that, strong letters from higher-ups at a place like RMS are probably just as noteworthy.

2) From the PI's perspective, taking a graduate student is a long-term investment. You would occupy a spot that could be offered to someone else, so in addition to promising productivity, PI's generally prefer the person have the goal of continuing on and pursuing an academic life.  Since you've been in industry, there is always the fear that at some point, you'll simply abdicate and return to industry.

I think you can spin your industry experience 'narrative' to your advantage.  First, you can stress that your time in industry did not meet your needs for academic development.  In other words, only academics provides the platform to realize your highly technical goals.  Second, people in industry usually have a very strong work ethic and know how to get things done; something that is often lacking in new graduate students.  You might consider documenting just how productive you have been.
