1.1.3 Replace propriety coded characters
Description
In addition to SGML character coding, other proprietary character coding can be used by data
suppliers to code special characters.
For USPTO data, codes like “{UMLAUT OVER (A)}” and “{DOT OVER (E)}” can be found. These
coded characters should be replaced with their normal ASCII/ANSI equivalents whenever
possible.
Analysis
Proprietary coded characters are identified by querying the data for the following pattern:
“%{%}%”; “%[%]%” and “%(%)%”.
Not all query results have to be proprietary coded characters but the query result can be used
to identify all occurring proprietary coded characters.
Table 8 contains the proprietary coded characters that were found in the names.

Implementation
All occurrences of proprietary coded characters are replaced with their respective ASCII/ANSI
equivalent, as defined in Table 8, by executing several update queries on the data.
Results
Proprietary character codes have been replaced with their ASCII/ANSI equivalent in 62 names.
The possibility cannot be ruled out that other proprietary character codes are still present in the
names.
Impact
From 440,237 unique names to 440,206 unique names, an additional reduction of 31 names, or
a total reduction of 3,516 names (0.8%).
