Class Definition:
SUBCLASSES
Subclass:
1
Carboxylic acid esters:
This subclass is indented under subclass 1. Compounds under
Class 532, ... wherein the acid function entering into the
formation of the esters is a carboxyl group.
(1) Note. The traditional manner of naming esters has been
to define the acid and alcohol moieties that are interracted.
The basis for classifying esters in this class has been the
acid moiety.In this reclassification, the use of the acid
moiety as the primary basis for classification has been
retained. However, whenever it was determined that no further
subdivision of a body of patents could be established based
upon variants of the acid moiety and consistent with good
classification practice, further subdivision has been made on
the characteristics of the alcohol moiety. To avoid any
confusion, the schedule of subclass titles specifically
points out that a particular characteristic pertains to the
acid moiety or the alcohol moiety. This factor, combined with
the complexity of the compounds which involve pluralities of
acid and alcohol moieties, has made it essential to establish
a set of rules to determine which acid moiety and which
alcohol moiety is to control the classification.
RULES FOR CLASSIFYING CARBOXYLIC ESTERS
A. Compounds
I. General
(1) The first step in determining the classification of a
compound is to resolve it into the several acidic and
alcoholic moieties.
(2) If there is more than one acid moiety, the general rule
of superiority is applied to determine the acid moiety which
will control classification.
(3) Thereafter, the rule applied is that only those alcohol
moieties which esterify the selected acid moiety are
considered for classification.
(4) Where there is more than one alcohol moiety esterifying
a controlling acid moiety and it is necessary to determine
which alcohol moiety will control classification, the general
rules of superiority are applied.
The following examples illustrate these rules:
(a) Polyoxy alcohol B and two carboxylic acids, A and D
AC(=O) OBO(O=)CD Determine which of acids A or D has
priority to decide the classification.
(b) Polycarboxylic acid A and two alcohols B and D
BO(O )CAC(=O)OD If necessary, determine which of alcohols B
and D has priority to decide the classification.
(c) Oxy acid B, acylating acid A and alcohol D
AC(=O)OBC(=O)OD Determine which of acids A and B has
priority. If acid A has priority, then oxy acid B serves as
the alcohol moiety and D is ignored for classification. If
oxy acid B has priority, then alcohol D is considered for
classification and acid A is ignored.
(d) Polycarboxylic acid A, monocarboxylic acid E, polyoxy
alcohol D and monooxy alcohol B BO(O=)CAC(=O)ODO(O=)CE
Determine which of acids A and E takes priority. If acid A
has priority, then alcohols B and D are considered and acid E
is ignored. If necessary, determine priority as between
alcohols B and D to establish classification. If acid E has
priority, consider only alcohol D for classification and
ignore acid A and alcohol B.
(e) Polycarboxylic acid A, oxy acid B, monocarboxylic acid
E, monooxy alcohol F and polyoxy alcohol D
FO(O=)CAC(=O)OBC(=O)ODO(O=)CE Determine priority among acid
moieties A, B and E. If polycarboxylic acid A has priority,
then consider only F and B as the alcohol moieties and ignore
D and E. If necessary, determine priority between F and B as
alcohol moieties for classification. If oxy acid B has
priority, then only alcohol D is considered for
classification, ignoring F, A and E. If acid E has priority,
consider only alcohol D for classification, ignoring F, A and
B.
II. Polycarboxylic Acid Esters
The treatment of polycarboxylic acid esters has not changed
in this reclassification. However, since it presents
potential pitfalls for classification and search, the
problems are summarized here.
Esters of polycarboxylic acids where one or more of the
carboxyl groups are unesterified are classified with the
polycarboxylic acid esters where all carboxyl groups may be
in the free acid form or may be present as salts or as acid
halides.
When the unesterified carboxyl is reacted with an amine to
form an amide, the compound is classified in the appropriate
subclass of the group of esters containing nitrogen.
Since an acid halide group on an acid moiety which contains
an esterified carboxyl is the function which makes it a
polycarboxylic acid ester, such compound is not considered to
be halogenated, for classification purposes. However, when
the acid halide group is on an acid moiety which serves as
the alcohol portion of an ester of an acid with higher
priority, this restriction no longer applies and it may be
considered as a halogenated alcohol.
An anhydride of a half ester of a dicarboxylic acid with a
monocarboxylic acid is regarded for classification purposes,
as a monocarboxylic acid ester, e.g., BO(O=C)AC(=O)O(O=)CD
and the final classification will be determined by the
functional groups present on both A and D which form the
entire acid moiety.
An anhydride of a half ester of a dicarboxylic acid with
another dicarboxylic acid or half ester will be considered as
a polycarboxylic acid, e.g., BO(O=)CAC(=O)O(O=)CDC(=O)OH.
Here too, the final classification will be determined by the
functional groups present on both A and D which form the
entire acid moiety.
III. Phenolic Esters
The only exception to the rules set forth in I. above, is
that of phenolic esters of acyclic carboxylic acids. Here,
the primary basis of classification is the phenolic moitety,
with the acids providing a secondary basis when all
classifiable characteristics of the phenolic moiety have been
exhausted. As a further exception to this case, carbamic
acid esters of phenols have been made special and appear
before all other categories.
IV. Salts
As a general rule, a salt forming moiety will not be
considered as significant for classifying a carboxylic acid
ester, unless it is, per se, an ester classifiable in this
area, in which case its acid group will compete for priority
with the acid group of the ester to which it is ionically
bound. In this case, classification will be based solely on
that ionic moiety which is superior.
B. Processes
The rules of classification with respect to processes follow
the general rules as set forth in the class definition.
Since processes may appear in three different positions
within the schedule, this rule is amplified to cover the
three situations.
(a) When a process subclass appears as a first line indent
to a residual subclass and is ahead of and coordinate with a
series of product subclasses, it is considered as referring
to the subject matter of the residual subclass as well as the
coordinate product subclasses.
(1) If the claims are drawn to a product classifiable in the
residual subclass and a process classifiable in a process
subclass, the original patent is placed in the residual
subclass and cross referenced to the appropriate process
subclass.
(2) If the claims are drawn to products classifiable in a
coordinate product subclass as well as process claims
classifiable in a process subclass, the original patent is
placed in the appropriate process subclass and cross
referenced to the product subclass.
(3) If all the claims are drawn to a process classifiable in
a process subclass, the original is placed in the appropriate
process subclass.
(b) When a process subclass appears as an indent to a
product subclass it refers only to the subject of that
product subclass.
(1) When the patent contains claims classifiable both in the
product and the process subclass, the patent is placed as an
original in the product subclass and cross referenced to the
process subclass.
(2) If all the claims are drawn to a process classifiable in
the process subclass, the original patent is placed in the
process subclass.
(c) When process subclasses appear as a first line indent,
but below a series of coordinate product subclasses, then
they refer only to subject matter classifiable in the
residual subclass.
(1) If the patent contains claims to a product classifiable
in the residual subclass and claims classifiable in a process
subclass, the original patent is placed in the residual
subclass and cross referenced to the process subclass.
(2) If the claims are all drawn to a process classifiable in
a process subclass, the original patent is placed in the
process subclass.
(d) Where a patent has claims drawn only to a process for
which no subclass is provided, in all cases the patent is
placed in the subclass appropriate to the product being
produced.
(2) Note. This is the residual subclass for esters of
alicyclic carboxylic acids not specifically provided for in
