Thank both tctepreslm and Robert to explain the function of "said" in patent description very clearly.

Here comes another puzzle. I read an abstract in an U.S. Patent as the following:

Abstract
A color REaD IOI system in which a light source illuminates the photoconductor so as to erase that photoconductor after the development of black toner but before exposure and development of the next color image.

Comment # 1:

So this abstract could be rewritten as

Abstract
A color REaD IOI system in which a light source illuminates the photoconductor so as to erase said photoconductor after the development of black toner but before exposure and development of the next color image.

Comment # 2:

I also have a problem with this abstract regarding basic grammars. The subject of the abstract is “ A color REaD IOI system”, following by an “in which” cause. But where is the verb of the subject? Without a verb, that is not even a complete sentence. However, I might miss something since those statements are examined by number of patent attorneys and patent examiners before being issued. I must miss something here!

P.S. That is referred to the U.S. Pat No 5,794,106
