Hi,
I read patent 6,914,453 by IBM and trying to follow the paper's claim
pattern to write my claims.

The next question is:
What is the difference between Method and Apparatus in a patent claim
area?

The interesting thing happens with the claims:
The patent repeats all sentences in claims for Method with a few
changes to make up claims for Apparatus.

I will follow their patterns, but I really don't realize why to do them
repeatedly?

Any patent precedents that if not repeated, a very serious consequences
would follow?

Thank you.

Weng
