Is IDCC IP essential for GSM?

I'm not a techie, but my understanding is that IDCC's air interface was essential. This is the second time I'm seeing this statement.

Some industry observers estimate that up to 75 per cent of the world’s GSM phones use technology based on InterDigital’s designs.

I'd love some feedback on what we own. Has someone engineered around our patents and 25% of the market is using that IP and avoiding IDCC's? This would seem to indicate that IDCC's technology is not essential. That would be okay if it is still the most commercially viable, but it is not nearly as strong as essential.

Thanks,
Frank
