Appeal 2007-2127
Reexamination Control No. 90/006,621
methods of lexical and syntactic analysis and the mode of operation of
the present invention are substantially the same for both natural and
formal languages. Spreadsheet and database entries are also generally
entered in ASCII code or the equivalent binary code. For purposes of
illustration of the structure and operation of the present invention the
disclosed embodiment is shown and described herein as a processor of
a formal language; that is, a compiler of a programming language.
However, it will be understood that substantially the same structure,
operation, and lexical and syntactic analyses may be employed to
process the code of a natural language, such as, for example, by
utilizing lexical analysis to determine correct spelling and/or syntactic
analysis to determine correct grammar of the natural language code
being entered by an editor or word processor, or to process the code of
a spreadsheet or database.
5. The 1990 application also added disclosure not found in the 1982 and
1985 applications that stated (now at '603 patent, col. 3, lines 48-61):
It will be obvious to those skilled in the computer arts that the
same or equivalent hardware and software may be employed to
perform lexical and syntactic analysis of natural language code, or to
calculate the numeric code of a spreadsheet, concurrently in real time
as the user enters or edits such code at the keyboard.
6. The added disclosures in the 1990 application were omitted from the
1994 application, as filed, and in the issued '604 patent.
7. The '604 patent states that it is a continuation of the 1990 application,
which is said to be a continuation of the 1985 and 1982 applications
(col. 1, lines 6-15).
8. The '604 patent does not incorporate the 1990, 1885, or 1982
applications by reference.
