901.05(a) Citation Data [R-3]
Foreign patent publications that use Arabic and Roman numerals in lieu of names to indicate the date show in order the day, month, and year, or alternatively, the year, month, and day. Roman numerals always refer to the month.
Japanese patent application publications show the date in Arabic numerals by indicating in order the year of the reign of the Emperor, the month, and the day. To convert the Japanese year of the Emperor to the Western calendar year, for years prior to 1989, add 1925 to the JAPANESE YEAR. For example: 40.3.6 = March 6, 1965. For years after 1988, add 1988 to the JAPANESE YEAR.
Alphabetical lists of the foreign language names of the months and of the names and abbreviations for the United States of America follow. The lists set forth only selected commonly encountered foreign language names and do not include those which are similar to the English language names and thus easily translatable.
In using the lists, identification of the foreign language (except for Russian) is not necessary. The translation into English is ascertained by alphabetically locating the foreign language name on the list.
The list of the foreign language names and abbreviations for the United States is useful in determining whether a foreign language patent publication indicates the filing of a similar application in the United States.
