Definition statement
This subclass/group covers:

Relationship between large subject matter areas

Relationship between C08F, C08G, C08L, C09D and C09J

Polymers as such are classified in C08F or C08G. Polymers compositions are classified in C08L. Coating compositions or adhesive compositions are classified in C09D and C09J respectively.

C09D and C09J are seen as "related fields" of C08L - this structure has implications on search and classification.

For classification:

if the claims only pertain to an "adhesive composition...", only the C09J classification is given

if the claims pertain to a composition as such and to an adhesive (For example, "composition for use as an adhesive..."), both the C09J classification and the corresponding C08L classification are given.

For searching both groups are to be searched, regardless of the wording of the claims, since in many documents of C08L, a passage relating to the use of the composition for an adhesive can be found.

In cases where a coating composition contains an organic non-macromolecular compound but is not based on that compound, and such a compound is of interest, classification could be made in subclass C08K or as an additive in group C08J 3/00 (e.g. C08J 3/24 for crosslinking agents) or C09D 7/12. This may be in addition to classification in C09D 101/00-C09D 201/00.

Special rules of classification

Coatings of polymers with organic or inorganic additives should be classified in C09D and C08K for the non-macromolecular component.

Example: A coating composition containing polyethylene and amino-propyltrimethoxysilane is classified in groups C09D 123/06 and C08K 5/544 as additional classification.

Use of C-Sets:

When two or more polymers are present in an adhesive composition, classification is given in the form of C-sets: the polymer in majority is given a C09D classification (see below), and the minor components are characterised by Indexing Codes. The Indexing Codes are chosen from C08L or C08K and they may be linked or unlinked. The polymer in majority is always first in the C-set.

Therefore at least one Indexing Code must always be present when more than one polymer is mentioned.

This method of classification is applied in groups C09D 101/00 to C09D 201/00 and subgroups.

Examples:

a: A coating composition containing 80 parts of polyethene and 20 parts of polyvinylchloride is classified in groups (C09D 123/06, C08L 27/06).

b: A coating composition containing 50 parts of polyethene and 50 parts of polyvinylchloride is classified in (C09D 123/06, C08L 27/06) and in groups (C09D 127/06, C08L 23/06).

c: A coating composition containing 90 parts of polysiloxane (C09D 183/04), further containing a polyester (C08L 67/00) and an alcohol is classified in (C09D 183/04, C08L 67/00, C08K 5/05).

After the notation of C09D 107/00 - C09D 121/02, classification is given in the form of C-sets, as explained in the Rules at subclass level.

Inorganic or non-macromolecular organic materials as compounding agents are classified in C08K; Compositions classified in C08K according to note 3 of C08K, are not classified in C08L. However, if a composition contains two polymers and an additive following C08K, classification is made in C08L and an Indexing Code from C08K will be given.

Examples:

a: A coating composition comprising a blend of 60 parts polybutadiene (C09D 109/00) and 40 parts polyamide (C08L 77/00) is classified in (C09D 109/00, C08L 77/00).

b: A coating composition comprising a blend of 50 parts polybutadiene (C09D 109/00) and 50 parts polyamide (C09D 177/00) is classified in (C09D 109/00, C08L 77/00) and (C09D 177/00, C08L 9/00).

c: A coating composition comprising a blend of 60 parts polybutadiene (C09D 109/00), 40 parts natural rubber (C08L 7/00) and 40 parts of silica is classified in (C09D 109/00, C08L 7/00, C08K 3/36).

Compositions are classified according to the mutual proportions by weight of only the macromolecular constituents;

Compositions are classified according to the macromolecular constituent or constituents present in the highest proportion: if all these constituents are present in equal proportions the composition is classified according to each of these constituents.

Special rules of classification within this group

The main groups of C09D 123/00 should not be used.

Majority rule:

For compositions

If C09D 123/00 relates to a compositions and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes in the form in C-Sets. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given.

For Copolymers

Copolymers get the symbol of the major component, except if there is a lower group which specifies the comonomer in minority (see also last place rule), e.g. ethylene butene copolymers (ethylene comonomer in majority) would be classified in C09D 123/0815, and not in C09D 123/20, but ethylene butene copolymers (butene in majority) would be classified in C09D 123/20, not in C09D 123/0815

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

Classification is given in the form of C-sets, as explained in the Rules at subclass level.

Remark: Note 2 is not relevant for C09D 123/00. All documents from before 2003 are reclassified.

Examples:

a. A coating of a blend of 60 parts polyethylene (C09D 123/06) and 40 parts polyamide (C08L 77/00) is classified in (C09D 123/06, C08L 77/00).

b. A coating of a blend of 50 parts polyethylene (C09D 123/06) and 50 parts polyamide (C09D 177/00) is classified in (C09D 123/06, C08L 77/00) and (C09D 177/00, C08L 23/06).

c. A coating based on a composition of polyethylene and containing CaCO3 is classified in C09D 123/06 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 123/06, C08L 77/00, C08K 3/26).

d. A coating based on a composition based on a first polyethylene (C09D 123/06) and containing a second polyethylene, a phenol and silica is classified in (C09D 123/06, C08L 23/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. A coating based on a composition containing a polyamide in majority, a polyester and a polyethylene is classified in (C09D 177/00, C08L 67/00, C08L 23/06) and C08L 2205/03.

f. Coatings of compositions containing two polymers of the same .dot group, for example compositions of two ethylene vinylacetate copolymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09D 123/0853, C08L 23/0853) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications) and C08K (for inorganic or organic non-macromolecular additives) are used.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings based on polyethylene, but subject-matter of the claim is a coating of polyolefin, the document is classified under coatings of polyethylene, e.g. (C09D 123/06, C08L--/--).

In C09D 123/00, coatings which have only one polymeric component are also classified, e.g. C09D 123/0815 is used for a coating of only one ethylene vinylacetate polymer.

Special rules of classification within this main group

This group should not be used.

Majority rule:

For compositions

If C09D 133/00 relates to composition of two or more polymers, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes in the form in C-Sets. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes of C08L for all polymers in minority and additives are given.

For Copolymers

Copolymers get the classification of the major component, except if there is a lower group which specifies the comonomer in minority. A coating composition based on a copolymer of ethylene and acrylic acid therefore is to be classified in C09D 123/0869 (ethylene in majority), but in C09D 133/02 if acrylic acid is in majority. However, a coating based on a copolymer of acrylic ester and acrylonitrile (acrylic ester in majority) would be classified in C09D 133/18. The monomer composition of the main polymer component can be characterised by Indexing Codes of C08F.

The classification of the main component polymer of the composition should be according to the most specific, or reactive monomer, e.g. glycidyl methacrylate and not methyl methacrylate in a copolymer of glycidyl methacrylate and methyl methacrylate. All comonomers of the main polymeric component should be characterised by their Indexing Codes in C08F (C08F 220/32 and C08F 220/14).

Remark: Note 2 is relevant for C09D 133/00. Documents from before 2003 are not reclassified.

Examples:

a. A coating composition of 60 parts polymethyl methacrylate (C09D 133/12) and 40 parts polyamide (C08L 77/00) is classified in (C09D 133/12, C08L 77/00).

b. A coating composition of 50 parts polymethyl methacrylate (C09D 133/12) and 50 parts polyamide (C09D 177/00) is classified in (C09D 133/12, C08L 77/00) and (C09D 177/00, C08L 33/12).

c. A coating composition based on polymethyl methacrylate and containing CaCO3 is classified in C09D 133/12 and C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 133/12, C08L 77/00, C08K 3/26).

d. A coating composition based on a first polymethyl methacrylate (C09D 133/12) and containing as a second polymer a copolymer of acrylic acid, a phenol and silica is classified in (C09D 133/12, C08L 33/02, C08K 5/13, C08K 3/36) and C08L 2205/02.

e. A composition containing a polyamide in majority, a polyester and a polymethyl methacrylate is classified in (C09D 177/00, C08L 67/00, C08L 33/12) and C08L 2205/03.

f. Coating compositions containing two polymers of the same .dot group, for example compositions of two polymers am hydroxyl containing acrylic ester, are characterised by the Indexing Code C08L 2205/025. The complete classification for such a compositions therefore would be (C09D 133/066, C08L 33/066) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g.. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F are used.

A coating composition containing next to another addition polymer a main component of a copolymer of acrylic ester, acrylamide and hydroxymethylmethacrylate therefore would be classified in (C09D 133/26, C08L--/--), C08F 220/10 and C08F 220/26, even if less acrylamide monomer is present than acrylic ester and hydroxymethylmethacrylate. If this main component would be in a blend with methylmethacrylate copolymer, an Indexing Code C08L 33/12 would additionally be given and the full classification would be (C09D 133/26, C08L 33/12), C08F 220/10 and C08F 220/26.

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used; for example terpolymers of styrene, vinyl acetate and methyl methacrylate in similar proportions would be classified in C09D 133/12 instead of C09D 125/00 or C09D 131/00. However, Indexing Codes of C08F should be given (C08F 212/08 for styrene, C08F 218/08 for vinyl acetate).

Classification guidance:

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe compositions of acrylic copolymers, but subject matter of the claim is a composition of acrylamide copolymer, the document is classified as composition of acrylamide copolymers (C09D 133/26, C08L--/--).

For compositions

If C09D 135/00 relates to a compositions and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised Indexing Codes in the form of C-Sets. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers

Copolymers get the symbol of the major component, except if there is a lower group which specifies the comonomer in minority (see also last place rule), i.e. ethylene maleic anhydride copolymers (ethylene in majority) would be classified in C09D 123/0869, and not in C09D 135/00, but ethylene maleic anhydride copolymers (maleic anhydride in majority) would be classified in C09D 135/06, not in C09D 123/0869

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Remark: Note 2 is relevant for C09D 135/00. Documents from before 2003 are not reclassified.

Examples:

a. A coating of a blend of 60 parts styrene-maleic anhydride copolymer (C09D 135/06) and 40 parts polyamide (C08L 77/00) is classified in (C09D 135/06, C08L 77/00).

b. A coating of a blend of 50 parts styrene-maleic anhydride copolymer (C09D 135/06) and 50 parts polyamide (C09D 177/00) is classified in (C09D 135/06, C08L 77/00) and (C09D 177/00, C08L 35/06).

c. A coating of a composition based on styrene-maleic anhydride copolymer and containing CaCO3 is classified in C09D 135/06 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 135/06, C08L 77/00, C08K 3/26).

d. A coating of a composition based on a first styrene-maleic anhydride copolymer (C09D 135/06) and containing a second styrene-maleic anhydride copolymer, a phenol and silica is classified in (C09D 135/06, C08L 35/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. A coating of a composition containing a polyamide in majority, a polyester and a styrene-maleic anhydride copolymer is classified in (C08L 77/00, C08L 67/00, C08L 35/06) and C08L 2205/03.

f. A coating of compositions containing two polymers of the same .dot group, for example compositions of two styrene-maleic anhydride copolymer polymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 135/06, C08L 35/06) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09D 135/00.

Therefore a terpolymer of styrene, maleic anhydride and acrylic amide should additionally be characterised by an Indexing Code C08F 220/56.

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings of compositions of styrene-maleic anhydride, but subject matter of the claim is a coating of a composition of a vinyl aromatic copolymer, the document is classified as coating composition of styrene maleic anhydride copolymer (C09D 135/06, C08L--/--).

Further subdivisions:

Coatings based on copolymers of unsaturated esters, e.g. acrylic ester with a monomer of C09D 135/00, e.g. maleic anhydride which have the ester in majority should be classified in C09D 133/00 and maleic anhydride should be characterised by an Indexing Code of C08F (C08F 222/04).

Coatings of copolymers of unsaturated nitriles, e.g. acrylonitrile with a monomer of C09D 135/00, e.g. maleic anhydride which have the nitrile in majority should be classified in C09D 133/00 and maleic anhydride should be characterised by an Indexing Code of C08F (C08F 222/04).

Majority rule:

For compositions

If C09D 137/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes, in the form of C-Sets. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given.

For Copolymers

In C09D 137/00, coatings do not get the classification of the major component of the monomer of the copolymers. A coating based on a copolymer of diene and vinylfuran, which has only a low content of vinyl furan, would be classified in C09D 137/00. Additional classification in C09D 109/00 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 236/00 for dienes).

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, C-Sets are used as explained in the Rules at subclass level.

Remark: Note 2 is relevant for C09D 137/00. Documents from before 2003 are not reclassified.

Examples:

a. A coating of a blend of 60 parts diene vinyl furan copolymer (C09D 137/00) and 40 parts polyamide (C08L 77/00) is classified in (C09D 137/00, C08L 77/00).

b. A coating of a blend of 50 parts diene vinyl furan copolymer (C09D 137/00) and 50 parts polyamide (C09D 177/00) is classified in (C09D 137/00, C08L 37/00), and (C09D 177/00, C08L 37/00).

c. A coating of a composition based on diene vinyl furan copolymer and containing CaCO3 is classified in C09D 137/00 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 137/00, C08L 77/00, C08K 3/26).

d. A coating of a composition based on a first diene vinyl furan copolymer (C09D 137/00) and containing a second diene vinyl furan copolymer, a phenol and silica is classified in (C09D 137/00, C08L 37/00, C08K 5/13, C08K 3/36) and C08L 2205/025.

e. A coating of a composition containing a polyamide in majority, a polyester and a diene vinyl furan copolymer is classified in (C08L 77/00, C08L 67/00, C08L 37/00) and C08L 2205/03.

f. A coating of compositions containing two polymers of the same .dot group, for example compositions of two diene vinyl furan copolymer polymers, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 137/00, C08L 37/00) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09D 137/00

Therefore a terpolymer of diene, maleic anhydride and vinyl furan should additionally be characterised by an Indexing Code C08F 220/56 and C08F 222/00

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings of compositions of diene vinyl furan, but subject matter of the claim is a coating of a composition of a diene copolymers, the document is classified as coating composition of a vinyl furan copolymer (C09D 137/00, C08L--/--).

Majority rule:

For compositions

If C09D 139/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers

In C09D 139/00, coatings do not get the symbol of the major component of the monomer of the copolymers. A coating based on a copolymer of acrylic ester and vinyl pyridine, which has a lower content of vinyl pyridine than acrylic ester, would also be classified in C09D 139/08. Additional classification in C09D 133/08 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 220/10 for acrylic esters)

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

c. A coating of a composition based on vinyl pyrrolidone copolymer and containing CaCO3 is classified in C09D 139/06 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 139/06, C08L 77/00, C08K 3/26).

d. A coating of a composition based on a first vinyl pyrrolidone copolymer (C09D 139/06) and containing a second vinyl pyrrolidone copolymer, a phenol and silica is classified in (C09D 139/06, C08L 39/06, C08K 5/13, C08K 3/36) and C08L 2205/025.

f. A coating of compositions containing two polymers of the same .dot group, for example compositions of two vinyl pyrrolidone copolymers, are characterised by the Indexing Code C08L 2205/025.

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09D 139/00

A copolymer of acrylic ester, maleic anhydride and vinyl pyrrolidone used in a coating adhesive therefore would be classified in C09D 139/06, C08F 220/10 and C08F 222/06

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings of compositions of acrylic ester vinyl pyrrolidone copolymers, but subject matter of the claim is a coating of a composition of a acrylic ester copolymer, the document is classified as coating composition of vinyl pyrrolidone copolymer (C09D 139/06, C08L--/--)

Special rules of classification within this main group

Majority rule:

For compositions

If C09D 141/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers

In C09D 141/00, coatings do not get the symbol of the monomer present in majority in the copolymers. A coating based on a copolymer of acrylic ester and vinyl thioethanol which has only a low content of vinyl thioethanol, would be classified in C09D 141/00. Additional classification in C09D 133/08 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 220/10 for acrylic ester)

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, C-Sets are used as explained in the Rules at subclass level.

Remark: Note 2 is relevant for C09D 141/00. Documents from before 2003 are not reclassified.

Examples:

a. A coating of a blend of 60 parts acrylic ester vinyl thioethanol copolymer (C09D 141/00) and 40 parts polyamide (C08L 77/00) is classified in (C09D 141/00, C08L 77/00).

b. A coating of a blend of 50 parts acrylic ester vinyl thioethanol copolymer (C09D 141/00) and 50 parts polyamide (C09D 177/00) is classified in (C09D 141/00, C08L 77/00) AND (C09D 177/00, C08L 41/00).

c. A coating of a composition based on acrylic ester vinyl thioethanol copolymer and containing CaCO3 is classified in C09D 141/00 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 141/00, C08L 77/00, C08K 3/26).

d. A coating of a composition based on a first acrylic ester vinyl thioethanol copolymer (C09D 141/00) and containing a second acrylic ester vinyl thioethanol copolymer, a phenol and silica is classified in (C09D 141/00, C08L 41/00, C08K 5/13, C08K 3/36) and C08L 2205/025.

.

e. A coating of a composition containing a polyamide in majority, a polyester and a acrylic ester vinyl thioethanol copolymer is classified in (C08L 77/00, C08L 67/00, C08L 41/00) and C08L 2205/03.

f. A coating of compositions containing two polymers of the same .dot group, for example compositions of an acrylic ester vinyl thioethanol copolymer polymers with two different polyethylenes, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 141/00, C08L 23/06), C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09D 141/00

Therefore a terpolymer of acrylic ester, maleic anhydride and vinyl thioethanol should additionally be characterised by an Indexing Code C08F 220/10 and C08F 222/00

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings of compositions of acrylic ester vinyl thioethanol, but subject matter of the claim is a coating of a composition of a acrylic copolymers, the document is classified as coating composition of a vinyl thioethanol copolymer (C09D 141/00, C08L--/--).

Special rules of classification within this main group

Majority rule:

For compositions

If C09D 143/00 relates to a composition and two or more polymers are present, classification is given as follows: the polymer in majority is given a C09D classification (see above), and the minor components are characterised by Indexing Codes. In the case that several polymers can be in majority, several C09D symbols for the polymers which are possibly in majority and the Indexing Codes for all polymers in minority and additives are given

For Copolymers

In C09D 143/00, coatings do not get the symbol of the major component of the monomer of the copolymers. A coating based on a copolymer of acrylic ester and vinyl silane, which has a lower content of vinyl silane than acrylic ester, would also be classified in C09D 143/04. Additional classification in C09D 133/08 should be considered. The comonomer in majority should get an Indexing Code in C08F (C08F 220/10 for acrylic esters)

However, coatings based on copolymers where the major comonomer is ethylene or propene, are classified in C09D 123/0892 or C09D 123/147

Last place rule:

If there are several possibilities to classify, the lowest alternative classification (last place) is used.

Use of C-Sets:

To indicate the nature of the second component in a system, C-Sets are used as explained in the Rules at subclass level.

Remark: Note 2 is relevant for C09D 143/00. Documents from before 2003 are not reclassified.

Examples:

a. A coating of a blend of 60 parts vinyl silane copolymer (C09D 143/04) and 40 parts polyamide (C08L 77/00) is classified in (C09D 143/04, C08L 77/00).

b. A coating of a blend of 50 parts vinyl silane copolymer (C09D 143/04) and 50 parts polyamide (C09D 177/00) is classified in (C09D 143/04, C08L 77/00) AND (C09D 177/00, C08L 43/04).

c. A coating of a composition based on vinyl silane copolymer and containing CaCO3 is classified in C09D 143/04 and gets an Indexing Code of C08K, e.g. in C08K 3/26. If this composition contains also a polyamide, then the classification will be (C09D 143/04, C08L 77/00, C08K 3/26).

d. A coating of a composition based on a first vinyl silane copolymer (C09D 143/04) and containing a second vinyl silane copolymer, a phenol and silica is classified in (C09D 143/04, C08L 43/04, C08K 5/13, C08K 3/36) and C08L 2205/025.

f. A coating of compositions containing two polymers of the same .dot group, for example compositions of two vinyl silane copolymer, are characterised by the Indexing Code C08L 2205/025. The complete classification for such compositions therefore would be (C09D 143/04, C08L 43/04) and C08L 2205/025. The same applies for compositions of two polymers only distinguished by physical properties, e.g. molecular weight or density.

Indexing Codes

All Indexing Codes of C08L (for secondary or polymers in minority, properties, uses, applications), C08K (for inorganic or organic non-macromolecular additives) and C08F (for specific monomers) are used.

Indexing Codes of C08F are used for specific monomers, which are part of the copolymer classified in C09D 143/00

A copolymer of acrylic ester, maleic anhydride and vinyl silane used in a coating adhesive therefore would be classified in C09D 143/04, C08F 220/10 and C08F 222/06

Classification guidance

Documents are preferably classified according to the examples in the documents, not according to general claims, e.g. if the examples only describe coatings of compositions of acrylic ester vinyl silane copolymers, but subject matter of the claim is a coating of a composition of a acrylic ester copolymer, the document is classified as coating composition of vinyl silane copolymer (C09D 143/04, C08L--/--).

Coating compositions based on macromolecular compounds obtained by reactions forming a carbon-to-carbon link in the main chain; Coating compositions based on derivatives of such polymers
Definition statement
This subclass/group covers:

Coating compositions, e.g. paints, varnishes, lacquers based on polymers (I) obtained by reactions forming a carbon-carbon bond in the main chain other than polymers (II) obtained by reactions only involving the polyaddition of carbon-to-carbon unsaturated bonds. Said polymers (I) are themselves classified in C08G 61/00-C08G 61/128. The coating compositions comprise either other macromolecular compounds and/or other ingredients.

Relationship between large subject matter areas

Relationship with other subclasses of classes C08 and C09:

Macromolecular compounds per se obtained by reactions only involving the polyaddition of carbon-to-carbon unsaturated bonds (addition polymers) are classified in C08F. Compositions based on monomers of such polymers are treated in C08F, as well.

Macromolecular compounds obtained by reactions forming a carbon-carbon bond in the main chain other than polymers obtained by reactions only involving the polyaddition of carbon-to-carbon unsaturated bonds are classified in C08G 61/00 and subgroups. Compositions based on monomers of such polymers are also put in C08G 61/00 and subgroups.

Use or choice of inorganic or non-macromolecular organic materials as compounding agents are classified in C08K, any macromolecular components are classified in C08L.

Relationship with other main groups of the same subclass C09D:

Coating compositions based on polymers prepared by condensation reactions of aldehydes or ketones with phenols only are classified in groups C09D 161/04 - C009D161/16, since C009D161/00-C009D161/34 takes preference. For the same reasons, coating compositions based on condensation polymers of aldehydes or ketones only are classified in C09D 161/02. Coating compositions of polymers, which may otherwise be formed by carbon-carbon bond formation, but which are prepared by condensation reactions other than those involving the formation of carbon-carbon bonds in the main chain are put in the appropriate groups, e.g. C09D 179/04 for polypyrroles formed from amines and polyketones. Coating compositions based on polyketones are classified in C09D 173/00.

Further aspects:

In cases where a coating composition contains an organic non-macromolecular compound but is not based on that compound, and such a compound is of interest, classification could be made in subclass C08K or as an additive in group C08J 3/00, e.g. C08J 3/24 for crosslinking agents or C09D 7/12. This may be in addition to classification in C09D 101/00-C09D 201/00.

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Addition polymers
An addition polymer is a polymer which is formed by an addition reaction, where monomers bond together via rearrangement of bonds without the loss of any atom or molecule. This is in contrast to a condensation polymer which is formed by a condensation reaction where a molecule, such as water, is lost during the formation.
Condensation polymers
A condensation polymer is a polymer in which water or some other simple molecule is eliminated from 2 or more monomer molecules as they combine to form the polymer.

Compositions of oils, fats and waxes in minority
Special rules of classification within this group

- Oils, fats and waxes in solution, or together with other macromolecular compounds, or together with an inorganic or non-macromolecular organic additive are considered as a composition and are thus classified according to the rules of C08L. They are classified according to the mutual proportions by weight of only the macromolecular constituents, in particular according to the macromolecular constituent present in the highest proportion. If all the constituents are present in equal proportions, the composition is classified according to each of these constituents.

- Compositions containing oils, fats and waxes and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K as indicated in the rules for C08L, but in the corresponding C08L subclass together with the corresponding Indexing Code(s) in C08K.

Ex.: A coating composition consisting of mineral wax and glass fibres (filler) is classified in C09D 191/08 and C08K 7/14

- Last place priority rule: Within each sub group of this group, in the absence of an indication to the contrary, classification is made in the last appropriate place.

- The subject-matter disclosed in both the claims and the examples of a patent document is to be classified.
