`The undersigned, John F. Bukacek, whose address is 6171 N. Sheridan Road #
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`I am well acquainted with the English and Japanese languages. I have in the past

`document. Based on my review, I note five discrepancies between the English translation
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`I have been asked to review the accuracy of the attached English translation of
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`I have reviewed this English translation and compared it with the Japanese
`
`discrepancies and providing the correct translation in each case. Apart from these five noted
`
`and the Japanese document. Accordingly,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`discrepancies, the English translation is accurate.
`
`I attach hereto an Errata noting these
`
`
`
`
`
`
`
`
`
`
`
`Accordingly,
`

`DECLARATION OF JOHN F. BUKACEK UNDER 37 C.F.R. § 1.68
`
`(CONTINUED)
`
`
`
`
`
`
`
`ERRATA FOR JAPANESE PATENT APPLICATION NO. H4-110388
`
`1. In the recapitulation of the Claim of the invention in the Detailed Description of the
`Invention, found on page 4, lines 21-26 of the English translation, the original
`Japanese states “(where m is from 1 to 5, n is from 1 to 5 and m + n = 5)” but in the
`English translation, the translator has modified “m + n = 5” to read “m + n = 6” so
`as to be in agreement with “m + n = 6” as set forth in the Claim of the invention.
`Although the original Japanese may be in error in stating “m + n = 5” in the
`recapitulation of the Claim, the reviewer suggests that the translator should have
`rendered the numeral as it is stated in the original, indicating with the Latin [sic]
`that the original Japanese says “m + n = 5 [sic].”
`
`2. In the recapitulation of the Claim of the invention in the Detailed Description of the
`Invention, found on page 4, lines 21-26 of the English translation, the original
`Japanese states the Title of the Invention as “a fluid for heat transfer purposes” but
`in the English translation, the translator modified “a fluid for heat transfer purposes”
`to read “a heat transfer medium” as set forth in the original Japanese in the Claim of
`the Invention. On page 4, lines 21-22 of the English translation, the translator
`should have rendered it as “a fluid for heat transfer purposes” as stated in the
`original Japanese.
`
`3. In Example 4 on page 13 (page 762) of the original Japanese, there appears a
`typographical error, i.e., “H3C-CF=C ク 2 (2-monofluoro-1-propene)” which was
`rendered as “H3C-CF=CH2 (2-monofluoro-1-propene)” in the English translation.
`Although the original Japanese contains a typographical error, the reviewer suggests
`that the translator should have rendered the formula as “H3C-CF=Cク2 [sic] (2-
`monofluoro-1-propene).”

`

`4. In the Claim of the invention, the original Japanese says “A heat transfer medium”
`but the Title of the Invention is “Fluid for heat transfer purposes.” The rendering by
`the translator of “A heat transfer medium” is an accurate rendering of the original as
`stated in the Claim of the invention, though it does not agree with the Title of the
`Invention.
`
`5. The review also notes that the translator rendered the Title of the Invention as
`“Fluids for heat transfer purposes” on page 2, line 11 of the English translation, but
`as “Fluid for heat transfer purposes” on page 3, line 3 of the English translation.
`The Japanese language typically does not distinguish between singular and plural.
`The reviewer suggests that the Title of the Invention should be rendered into
`English in the singular.
