I have no idea what you're talking about.

On the other hand, depending on the standards body you use, you may not 
be able to standardize without showing at least one reference

If there are patents that are valid, you may either have to pay license 
fees, or you won't be able to release that product in the country where 
the patent is hold. When you're doing open source, you may be even in 
bigger trouble because your open source license may be fundamentally 
incompatible with the license terms of the patent holder.

I just wanted to explain why people care, that's all.

Best regards, Julian
