Special rules of classification within this subclass

When a textile material is manufactured for special purposes or uses, then it is also classified in the corresponding subclasses.

When a composition or a compound appears to be essential, then it is also classified in the corresponding composition/ compound subclass.

When the textile structure appears to be essential, then it is classified in the corresponding subclass.

In case of composition comprising several compounds, a class is allocated for each compound.

In case of macromolecular compounds comprising several monomers or copolymers, a class is given for each monomer.

For example a copolyether-ester should be classified in D06M 15/53 and D06M 15/507.

A copolymer acrylic acid/styrene should be classified in D06M 15/233 and D06M 15/263.

In case of compounds bearing several functional groups, a class is given for each essential functional group.

Normally, the subject-matter disclosed in both the claims and the examples is to be classified. Other components mentioned or disclosed in the description can be optionally classified provided that their function is not essential.

In these cases class allocation is at the discretion of the classifier.

But in case the subject matter of the claim is too broadly defined or unclear, or too many possibilities are disclosed, for example, Markush formulas, then only the subject matter of the examples is classified.

And in case no examples are provided, it is recommended to allocate a class for the most probable compounds or combination of compounds or compositions.

In case of doubt between two groups/subgroups, it is recommended to allocate both.

To conclude, it is recommended that classification is complete as much as possible: it is always preferable to allocate too many classes than too few.

When possible and when relevant, it is strongly recommended to allocate Indexing Codes corresponding to the chemical nature of the fibre or the functionality of the treatment:

  • for example for an anti-shrinking treatment of wool, D06M 2101/12 and D06M 2200/45 should be allocated, because an anti-shrinking treatment of wool should be different from an anti-shrinking treatment of cotton;
  • on the contrary, for a treatment imparting flame resistance to textile materials made of cotton, D06M 2200/30 should be allocated, but D06M 2101/06 might be considered as optional.

Special rules of classification within this group

In this group, it might happen an overlapping with D06M 14/18-D06M 14/34. When it is not clear whether a graft polymerisation is taking place or not, or how the chemical compounds are reacting with the fibre, then it is recommended to use a double classification.

For example, when a plasma treatment is carried out in the presence of acrylic acid or ethylene, then a grafting reaction onto the fibre surface might occur. In case it is not explicitly mentioned, then both classes D06M 10/025 and D06M 14/28 should be allocated.
