In the invention content of patent application specification, "optimization" often appears. What are the specific meanings of these three words?

In the specification of a patent application, the word "preferred" usually indicates that a certain choice or method is a preferred choice. Specifically, it shows that this choice or method is more likely to be considered as having an inventive advantage or achieving better results than other possible choices or methods.

"Optimization" does not involve whether the invention can be realized, nor does it limit the content of the invention. It is just a descriptive word to indicate that the inventor thinks this choice or method is the best or the first choice.

In the patent application, the inventor can put forward many different options or methods, and each method has its advantages and disadvantages. The appearance of the word "first choice" can help readers better understand which option or method the inventor thinks is the most suitable.

It should be noted that "optimal" is not necessarily the best choice, nor is it necessarily the only feasible choice. When examining a patent application, the examiner needs to understand the meaning of "preference" in combination with the specific description in the specification and the intention of the inventor.
