I can not find them in http://www.freepatentsonline.com. Why?

Thank you Aya2002!
I had tried, but no these three patents in google. Is there another way to get? Thanks!

i think you need to check your information !

Thank you! The information is ok.
These three patents are provisional patents, so I can not find them through conventional method.
Are there any other ways to get provisional patents?

Well, sure. Go to a paid patent service and search the patent applications.

You can do so at Delphion.com for S140 per month as a premium member. There are probably other services.
