Description

Example of Execution

It is an issue of capital importance how many examples of execution you write on description. Competitors obtain useful information too much if you write too much. But in case of too few examples, a patent may be invalidated because invention for which a patent is sought is not stated in detailed explanation of the invention. You should write the examples within the minimum extent necessary.

Claims

The Number of claims

Less claims lead to lower cost. But if you only claim several examples of execution, a patent for them is ineffective due to a narrow range of the patent. So a superordinate concept of the examples should be claimed. However, superordinate concepts are difficult to be patented. So you should claim a combination of the superordinate concept, some intermediate concepts and the examples.
