Summary of the Judgment
1.

The present case is a suit against a trial decision that held a request forcorrection by the Plaintiff, who is a patentee, to be non-compliant and that invalidated
a patent with regard to an invention titled "COMPOSITIONS COMPRISING 2,3DICHLORO-1,1,1-TRIFLUOROPROPANE,
TRIFLUOROPROPENE,

2-CHLORO-1,1,1-

2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE,

2,3,3,3-TETRAFLUOROPROPENE" (Number of claims: 2).

OR

The issue of thepresent case is the presence or absence of a violation of the correction requirement.
2.

The present judgment recognized the Plaintiff's claim to be well founded, andrescinded the present trial decision.
(1)

The reasons are outlined as follows.

A correction of the scope of claims etc. must be made "within the scope of thematters disclosed in the description, claims, or drawings attached to a written
application" (Article 134-2, paragraph (9) and Article 126, paragraph (5) of the Patent
Act).

This can be interpreted as requiring that the invention be fully disclosed fromthe time of filing the original application to thereby ensure prompt granting of rights
and to prevent unforeseen disadvantages to third parties who acted on the premise of
the scope of the invention disclosed at the time of filing the application.

It isreasonable to interpret that the phrase "matters disclosed in the description, claims, ordrawings attached to a written application" means technical matters that can bederived by a person ordinarily skilled in the art after taking the entire disclosure of thedescription, claims, or drawings into overall consideration (hereinafter merelyreferred to as "the original technical matters").

In a case where a correction does not

introduce a new technical matter in relation to the original technical matters, it can bedeemed that the correction is made "within the scope of the matters disclosed in thedescription, claims, or drawings."

i

(2)

The contents of the original technical matters in the present case are as follows:[i] in preparing HFO-1234yf, by-products generated in the preparing process andimpurities contained in HFO-1234yf or its raw materials (HCFC-243db, HCFO1233xf, HCFC-244bb) can be present in small amounts as additional compounds; [ii]in Present Invention 1, 0.2 percent by weight or less of HFC-143a and 1.9 percent by
weight or less of HFC-254eb are included as the additional compounds; and [iii] insome cases, the amount of HFO-1234yf contained in a composition that may be aworking example of Present Invention 1 was 57.0, 77.0, 85.0, or 82.5 mole percent.
(3)

Among compounds of Present Invention 1 (a composition comprising HFO-

1234yf, HFC-143a, and HFC-254eb, wherein the composition comprises 0.2 percent
by weight or less of HFC-143a and 1.9 percent by weight or less of HFC-254eb), thepresent correction defined a lower limit of the contained amount of HFO-1234yf as
77.0 mole percent, and this numerical value itself is one that was stated in the present
description.

Then, the numerical value cannot be recognized to have remarkabletechnical significance even in light of the statement of the present description.

Thus,

the present correction cannot be deemed to have added a new technical matter withregard to Present Invention 1.
Therefore, the present correction does not introduce a new technical matter in
relation to the original technical matters with regard to Present Invention 1.
(4)

It is concluded that the present correction is recognized to be made "within thescope of the matters disclosed in the description, claims, or drawings."

Thus, thepresent trial decision erred in determining that the present correction does not comply
with the provision of Article 126, paragraph (5) of the Patent Act as applied mutatis
mutandis under Article 134-2, paragraph (9) of the same Act.

Therefore, Ground 1

for Rescission (Error in the determination on whether the correction complies with thecorrection requirement) as asserted by the Plaintiff is well founded.

Outline of the case
The present case is a suit against a trial decision (hereinafter referred to as "thePresent Trial Decision") that invalidated a patent with regard to inventions according
to Claims 1 and 2 of Patent No. 6752438 (hereinafter referred to as "the Present
Patent"), in which the issues are: the presence or absence of a violation of thecorrection requirement stipulated in Article 126, paragraph (5) of the Patent Act asapplied mutatis mutandis under Article 134-2 of the same Act; and the presence orabsence of a violation of the support requirement stipulated in Article 36, paragraph(6), item (i) of the same Act.
1. History of procedures at the JPO(1) The Plaintiff is a patentee of the Present Patent for the invention titled"COMPOSITIONS COMPRISING 2,3-DICHLORO-1,1,1-TRIFLUOROPROPANE,
2-CHLORO-1,1,1-TRIFLUOROPROPENE,

2-CHLORO-1,1,1,2-

TETRAFLUOROPROPANE, OR 2,3,3,3-TETRAFLUOROPROPENE."

For thePresent Patent, a divisional application was filed on September 4, 2019 (Filing date of
the original application: May 7, 2009, Priority claim under the Paris Convention: May
7, 2008, United States of America), and establishment of a patent right was registeredon August 21, 2020 (Exhibit Ko 46).
(2) The Defendant filed a request for a trial for invalidation of the Present
Patent (Number of claims: 2) on November 30, 2020.
1

The Japan Patent Officeexamined this request as the case of Invalidation Trial No. 2020-800115.

The

Plaintiff submitted a written request for correction (Exhibit Ko 32; hereina fter,
correction made by this written request for correction will be referred to as "thePresent Correction") on April 5, 2021, requesting that the Scope of Claims of the
Present Patent be corrected.

However, the Japan Patent Office held that the Present

Correction shall not be allowed, and rendered the Present Trial Decision that "thepatent for the inventions according to Claims 1 to 2 of Patent No. 6752438 shall be
invalidated" (for the overseas resident, 90 days were added to the statute oflimitations for filing an action) on August 17, 2022.

A certified copy of the Present

Trial Decision was served on the Plaintiff on the 26th of the same month.
The Plaintiff filed the present suit on December 15 of the same year.
2. Summary of the invention(1) The statement of Claims 1 and 2 in the Scope of Claims of the Present
Patent before the Present Correction is as follows (hereinafter, the term "claim" willrefer to a claim in the Scope of Claims of the Present Patent unless otherwise
specified; hereinafter the invention according to Claim 1 before the Present
Correction will be referred to as "Present Invention 1," the invention according to
Claim 2 before the Present Correction will be referred to as "Present Invention 2," andboth inventions will be collectively referred to as "the Present Invention").
[Claim 1]
A composition comprising HFO-1234yf, HFC-143a, and HFC-254eb, wherein
the composition comprises 0.2 percent by weight or less of HFC-143a and 1.9 percent
by weight or less of HFC-254eb.
[Claim 2]
A composition comprising HFO-1234yf, HFC-143a, and HFC-254eb, wherein
the composition comprises 0.1 to 0.2 percent by weight of HFC-143a and 0.7 to 1.9
percent by weight or less of HFC-254eb.
(2) Contents of the Present Correction(Correction Matter 1)
The statement "HFO-1234yf" in Claim 1 is corrected to recite "77.0 molepercent or more of HFO-1234yf."(Correction Matter 2)
The statement "HFO-1234yf" in Claim 2 is corrected to recite "82.5 molepercent or more of HFO-1234yf."
3. Summary of reasons of the Present Trial Decision(1) Whether the Present Correction complies with the correction requirement
2A. Contents of Correction Matters 1 and 2
Correction Matters 1 and 2 pertaining to the Present Correction are as
mentioned in 2(2) above.
B. Examination on whether or not Correction Matter 1 is compliant(A) The invention according to Claim 1 after the Present Correction(hereinafter, Present Invention 1 and Present Invention 2 after the Present Correction
will be referred to as "Present Correction Invention 1" and "Present Correction
Invention 2," respectively, and both inventions will be collectively referred to as "thePresent Correction Invention") defines a composition comprising all of "HFO 1234yf," "HFC-143a," and "HFC-254eb," in which, regarding the contained amountof these components, the contained amount of "HFC-143a" is 0.2 percent by weight orless, and the contained amount of "HFC-254eb" is 1.9 percent by weight or less, andin which the contained amount of "HFO-1234yf" is 77.0 mole percent or more; i.e.,the composition encompasses the contained amount of "HFO-1234yf" being 77.0
mole percent and comprises "HFO-1234yf" with any content rate within a high rangethat exceeds 77.0 mole percent.
(B) Regarding the composition comprising all of "HFO-1234yf," "HFC-143a,"and "HFC-254eb," Table 5 ([Table 6]) (hereinafter merely referred to as "Table 5([Table 6])") in the description and drawings attached to a written application for the
Present Patent (hereinafter collectively referred to as "the Present Description") does
not show that component analysis was performed for all of the components incompositions prepared through a reaction of HFC-244bb.

In addition, the reaction of

HFC-244bb was not intended to prepare a composition comprising the specificcomponent.

Table 5 ([Table 6]) only shows that component analysis was performed

for outflow in the middle of the reaction (during conversion) of HFC-244bb.

It isunclear whether components contained in the outflow are only those listed in Table 5([Table 6]) (the component analysis might be limited to check preparing progress).
Further, since Table 5 ([Table 6]) does not show molecular weights and weights ofcomponents regarded as unknown, the contained amounts of "HFC-143a" and "HFC254eb" expressed as percent by weight are unclear.

Thus, the contained amount of"HFO-1234yf" expressed as mole percent in Present Correction Invention 1 cannot bederived from numerical values of the contained amount of "HFO-1234yf" in Table 5([Table 6]).

Therefore, a person ordinarily skilled in the art cannot derive thecomposition of Present Correction Invention 1 from the statement of the Present
Description.
(C) The Present Description only states matters supporting that the statement
3

"The applicants have found that in preparing new compounds with low global
warming potential, such as 1234yf, certain additional compounds are present in small
amounts." ([0003]; hereinafter, a four-digit number enclosed in [ ] refers to aparagraph number of the Present Description unless otherwise specified).

For

example, even if the statement on a composition comprising more than 85.0 molepercent of "HFO-1234yf" is examined, a method for obtaining a composition
comprising predetermined amounts of additional compounds as defined in Claim 1
after the Present Correction cannot be understood.

In addition, from the statement of

the Present Description, it cannot be deemed that the contained amount of HFO 1234yf has a lower limit as a preferable range and that the lower lim it is 77.0 molepercent.
(D) Thus, Correction Matter 1 introduces a new technical matter in relation to
the technical matters derived by taking the entirety of the Present Description into
overall consideration and should be deemed not to be made within the scope ofmatters disclosed in the Present Description.

Therefore, Correction Matter 1 does

not comply with the provision of Article 126, paragraph (5) of the Patent Act asapplied mutatis mutandis under Article 134-2, paragraph (9) of the same Act.
C. Examination on whether or not Correction Matter 2 is compliant(A) Correction Matter 2 is intended to limit the contained amount of "HFO1234yf" to "82.5 mole percent or more" regarding the "composition comprising HFO 1234yf, HFC-143a, and HFC-254eb, wherein the composition comprises 0.1 to 0.2
percent by weight of HFC-143a and 0.7 to 1.9 percent by weight or less of HFC254eb" in Claim 2 before the Present Correction.
(B) However, in Table 5 ([Table 6]), there is no other choice but to deem thatthe contained amounts of "HFC-143a" and "HFC-254eb" expressed as percent by
weight are unclear.
In addition, the Present Description does not state about a composition
comprising more than 85.0 mole percent of "HFO-1234yf" and predeterminedamounts of additional compounds as defined in Claim 2 after the Present Correction,
which is the same as in B(C) above.
(C) Thus, Correction Matter 2 introduces a new technical matter in relation to
the technical matters derived by taking the entirety of the Present Descripti on into
overall consideration and should be deemed not to be made within the scope ofmatters disclosed in the Present Description.

Therefore, Correction Matter 2 does

not comply with the provision of Article 126, paragraph (5) of the Patent Act asapplied mutatis mutandis under Article 134-2, paragraph (9) of the same Act.

D. For the foregoing reasons, the Present Correction is not allowable.
(2) Violation of the support requirement of the Present Invention
A. Taking into consideration the Present Description together with thestatement of the Scope of Claims, the Present Invention can be deemed to be premisedon a composition in which contained amounts of certain additional compounds
incorporated in preparing the compound HFO-1234yf are very small and which isused for applications for which usefulness of the composition is confirmed.

Thus,

the problem of the Present Invention can be found to provide a composition thatcomprises 1234yf with low global warming potential (GWP) and that is useful forheat transfer compositions, aerosol propellants, foaming agents, blowing agents,
solvents, cleaning agents, carrier fluids, displacement drying agents, buffing abrasion
agents, polymerization media, expansion agents for polyolefins and polyurethanes,
gaseous dielectrics, fire extinguishers, and fire extinguishers in the form of liquid orgas (hereinafter referred to as "heat transfer compositions, etc.").
B. In Table 5 ([Table 6]), there is no other choice but to deem that thecontained amounts of "HFC-143a" and "HFC-254eb" expressed as percent by weight
are unclear.

In addition, from the statement of the Present Description, it cannot be

understood that the composition comprising all of "HFO-1234yf," "HFC-143a," and"HFC-254eb," in which predetermined amounts of "HFC-143a" and "HFC-254eb" arecontained, like the Present Invention, is stated.
Further, the Present Invention does not define the contained amount of "HFO1234yf" and can also comprise components other than "HFO-1234yf," "HFC-143a,"and "HFC-254eb."

Thus, if "HFO-1234yf" is contained in very small amount (e.g., alarge amount of refrigerant with high GWP is contained) or if large amounts of othercompounds that are toxic to the human body, easily flammable or explosive,
excessively corrosive to equipment, or the like are contained, it is clear that the factthat the composition comprises "HFO-1234yf" with low global warming potential(GWP) does not make it useful for heat transfer compositions, etc.
Furthermore, regarding compositions falling within the full scope of the
Present Invention (that can comprise any component other than "HFO-1234yf," "HFC143a," and "HFC-254eb"), the Present Description neither states that it was confirmed
whether such compositions were useful for heat transfer compositions, etc., nor isthere common general technical knowledge that the compositions falling within thefull scope of the Present Invention will be useful for heat transfer compositions, etc.
Thus, a person ordinarily skilled in the art cannot recognize that the problem of
the Present Invention is solved by the Present Invention that is not originally stated in5the Present Description, nor can a person ordinarily skilled in the art recognize thatthe problem of the Present Invention is solved by the Present Invention that does notdefine that the predetermined amount of "HFO-1234yf" is contained and that does notdefine components other than "HFO-1234yf," "HFC-143a," and "HFC-254eb."
C. Therefore, the statement of Claims 1 and 2 before the Present Correction
does not comply with the provision of Article 36, paragraph (6), item (i) of the PatentAct.
(omitted)
No. 5

Judgment of this court
1. Present Invention before the Present Correction(1) The Present Description states as shown in Attachment "Patent Gazette"(Exhibit Ko 46).
(2) Summary of the Present Invention
According to the statement in (1) above, the Present Invention relates to a fieldof compositions useful for heat transfer compositions, etc., and new environmental
regulations have led to the need for new compositions for use in refrigeration, airconditioning, and heat pump apparatus, and against this background, compounds withlow global warming potential are of particular interest, and under these circumstances,in the Present Invention, it has been found that in preparing such new compounds withlow global warming potential, such as 1234yf, certain additional compounds arepresent in small amounts ([0001] to [0003]).
2. Whether or not the Present Correction is compliant(1) The Present Correction intends that the statement "HFO-1234yf" in Claim 1
should be corrected to recite "77.0 mole percent or more of HFO-1234yf" (Correction
Matter 1) and that the statement "HFO-1234yf" in Claim 2 should be corrected torecite "82.5 mole percent or more of HFO-1234yf" (Correction Matter 2), both ofwhich define a lower limit for the contained amount of HFO-1234yf in thecomposition of the Present Invention.
(2) The Present Correction was requested by the Plaintiff together with thesubmission of a written answer (Exhibit Ko 31) in response to the service of a written
request (Exhibit Ko 30) that was filed for a trial for invalidation of the Present Patent(Exhibit Ko 32; the main clause of Article 134-2, paragraph (1) of the Patent Act).
(3) A correction of the Scope of Claims, etc. must be made "within the scope ofthe matters disclosed in the description, claims, or drawings attached to a written
6application" (Article 134-2, paragraph (9) and Article 126, paragraph (5) of the Patent
Act).

This can be interpreted as requiring that the invention be fully disclosed fromthe time of filing the original application to thereby ensure prompt granting of rights
and to prevent unforeseen disadvantages to third parties who acted on the premise of
the scope of the invention disclosed at the time of filing the application.

It isreasonable to interpret that the phrase "matters disclosed in the description, claims, ordrawings attached to a written application" means technical matters that can bederived by a person ordinarily skilled in the art after taking the entire disclosure of thedescription, claims, or drawings into overall consideration (hereinafter merelyreferred to as "the original technical matters").

In a case where a correction does not

introduce a new technical matter in relation to the original technical matters, it can bedeemed that the correction is made "within the scope of the matters disclosed in thedescription, claims, or drawings."(4) Correction Matter 1
A. (A) The statement of the Scope of Claims according to Present Invention 1
recites "A composition comprising HFO-1234yf, HFC-143a, and HFC-254eb, wherein
the composition comprises 0.2 percent by weight or less of HFC-143a and 1.9 percent
by weight or less of HFC-254eb."

According to the literal wording, it is sufficient if

the composition comprises HFO-1234yf, 0.2 percent by weight or less of HFC-143a,and 1.9 percent by weight or less of HFC-254eb, and it can be interpreted that thecomposition can fall within the Scope of Claims regardless of the contained amount of
HFO-1234yf.
(B) The Present Description states that "The applicants have found that in
preparing new compounds with low global warming potential, such as 1234yf, certain
additional compounds are present in small amounts." ([0003]), "According to thepresent invention, there is provided a composition comprising HFO-1234yf and at
least one additional compound selected from the group consisting of HFO -1234ze,
HFO-1243zf, HCFC-243db, HCFC-244db, HFC-245cb, HFC-245fa, HCFO-1233xf,
HCFO-1233zd, HCFC-253fb, HCFC-234ab, HCFC-243fa, ethylene, HFC-23, CFC-13,
HFC-143a, HFC-152a, HFO-1243zf, HFC-236fa, HCO-1130, HCO-1130a, HFO-1336,
HCFC-133a, HCFC-254fb, HCFC-1131, HFC-1141, HCFO-1242zf, HCFO-1223xd,
HCFC-233ab, HCFC-226ba, and HFC-227ca.

The composition comprises less thanabout 1 percent by weight of the at least one additional compound." ([0004]).

Inview of these statements, the Present Description can be deemed to state that in
preparing HFO-1234yf, certain additional compounds are present in small amounts
and that there is less than about 1 percent by weight of HFC-143a as one of the7

additional compounds contained in the composition of the Present Invention.
In addition, taking into the overall consideration the statements o f [0013],[0016], [0019], [0022], [0030], and [Figure 1], the Present Description can be deemed
to state that by-products generated in the process of preparing HFO-1234yf andimpurities contained in HFO-1234yf or its raw materials (HCFC-243db, HCFO1233xf, HCFC-244bb) fall under the additional compounds.
Further, Working Example 15 stated in [0121] to [0123] (Table 5 ([Table 6]))states four examples of the compositions comprising HFO-1234yf, HFC-143a, andHFC-254eb in which the compositions were generated upon conversion from HCFC244bb into HFO-1234yf without a catalyst (heated temperatures (°C) are 550, 574,
603, 626, respectively), and states that the contained amounts of HFO-1234yf in thecompositions were 57.0, 77.0, 85.0, and 82.5 mole percent, respectively.
(C) However, the Present Description states neither any suggestion of technicalsignificance about comprising HFC-143a and HFC-254eb as the additional
compounds in preparing HFO-1234yf, nor any suggestion of technical significanceabout the amounts of HFO-1234yf in the compound being 57.0, 77.0, 85.0, and 82.5
mole percent.
B. On the basis of each statement in A above, the contents of the originaltechnical matters in the present case are as follows: [i] in preparing HFO -1234yf, byproducts generated in the preparing process and impurities contained in HFO-1234yf
or its raw materials (HCFC-243db, HCFO-1233xf, HCFC-244bb) can be present insmall amounts as additional compounds; [ii] in Present Invention 1, 0.2 percent by
weight or less of HFC-143a and 1.9 percent by weight or less of HFC-254eb are
included as the additional compounds; and [iii] in some cases, the amount of HFO 1234yf contained in a composition that may be a working example of Present
Invention 1 was 57.0, 77.0, 85.0, or 82.5 mole percent.
C. Among compounds of Present Invention 1, the Present Correction defined alower limit of the contained amount of HFO-1234yf as 77.0 mole percent, and thisnumerical value itself is one that was stated in the Present Description, as mentionedin A(B) and B above.

Then, the numerical value cannot be recognized to haveremarkable technical significance even in light of the statement of the Present
Description.

Thus, the Present Correction cannot be deemed to have added a newtechnical matter with regard to Present Invention 1.
Therefore, the Present Correction does not introduce a new technical matter in
relation to the original technical matters with regard to Present Invention 1.
(5) Correction Matter 2
8

A. The statement of the Scope of Claims according to Present Invention 2
recites "A composition comprising HFO-1234yf, HFC-143a, and HFC-254eb, wherein
the composition comprises 0.1 to 0.2 percent by weight of HFC-143a and 0.7 to 1.9
percent by weight or less of HFC-254eb."

According to the literal wording, it issufficient if the composition comprises HFO-1234yf, 0.1 to 0.2 percent by weight of
HFC-143a, and 0.7 to 1.9 percent by weight of HFC-254eb, and it can be interpreted
that the composition can fall within the Scope of Claims regardless o f the contained
amount of HFO-1234yf.
B. On the basis of each statement in A above and in (4)A(B) above, thecontents of the original technical matters in the present case are as follows: [i] in
preparing HFO-1234yf, by-products generated in the preparing process and impurities
contained in HFO-1234yf or its raw materials (HCFC-243db, HCFO-1233xf, HCFC244bb) can be present in small amounts as additional compounds; [ii] in Present
Invention 2, 0.1 to 0.2 percent by weight of HFC-143a and 0.7 to 1.9 percent by
weight of HFC-254eb are included as the additional compounds; and [iii] in somecases, the amount of HFO-1234yf contained in a composition that may be a working
example of Present Invention 2 was 57.0, 77.0, 85.0, or 82.5 mole percent.
C. Among compounds of Present Invention 2, the Present Correction defined alower limit of the contained amount of HFO-1234yf as 82.5 mole percent, and thisnumerical value itself is one that was stated in the Present Description, as mentioned
in B above and in (4)A(B) above.

Further, the numerical value cannot be recognized

to have remarkable technical significance even in light of the statement of the Present
Description.

Therefore, for the same reasons as mentioned in (4)C above, thePresent Correction does not introduce a new technical matter in relation to the originaltechnical matters with regard to Present Invention 2.
(6) Summary
Therefore, it should be deemed that the Present Correction does not introduce a
new technical matter in relation to the original technical matters.
3. Grounds for rescission
According to the above, it is concluded that the Present Correction isrecognized to be made "within the scope of the matters disclosed in the description,
claims, or drawings."

Thus, the Present Trial Decision erred in determining that the

Present Correction does not comply with the provision of Article 126, paragraph (5)of the Patent Act as applied mutatis mutandis under Article 134-2, paragraph (9) of
the same Act.

Therefore, Ground 1 for Rescission (Error in the determination onwhether the correction complies with the correction requirement) as asserted by the9Plaintiff is well founded.
In addition, regarding Ground 2 for Rescission as well, the invention subject tothe determination on a violation of the support requirement should be the Present
Correction Invention, whereas the invention determined by the Present Trial Decision
is the Present Invention.

Therefore, it is inescapable to rescind the Present Trial

Decision.
No. 6

Conclusion
For the foregoing reasons, the Plaintiff's claim is well founded and thus shallbe affirmed.

Therefore, the judgment is rendered as mentioned in the main text.
