Class 987
ORGANIC COMPOUNDS CONTAINING A Bi, Sb, As, OR P ATOM OR
CONTAINING A METAL ATOM OF THE 6TH TO 8TH GROUP OF THE
PERIODIC SYSTEM
Class Definition:
CROSS-REFERENCE ART COLLECTIONS
Class 987 provides an ANCILLARY and totally OPTIONAL search
for subject matter relating to certain types of ORGANIC
COMPOUNDS found under official Class 532. This class has been
developed and relates to the subject matter in Class C07F,
subgroups 9/00-19/00 of the International Patent
Classification System (IPC).
The subject matter of this class encompasses acyclic,
carbocyclic, or heterocyclic compounds containing elements
other than carbon, hydrogen, nitrogen, sulfur, selenium,
tellurium, halogen, and elements of Groups I-IV of the
Periodic System.
This Class Does NOT Provide for Organic Compounds Relating
to:
(1) Peptides, proteins, or enzymes ; (2) Sugars or
derivatives thereof, nucleosides, nucleotides, nucleic acids,
saccharides, or polysaccharides or derivatives thereof; (3)
Steroids; (4) Macromolecular compounds; (5) Dyes.
The Technical Subject Matter of This Class Relates to:
(1) Organic compounds containing a heavy metal of the 6th to
8th Group of the Periodic System
(2) Organic compounds containing Bismuth, Antimony, or
Arsenic
(3) Organic compounds containing Phosphorus
See Subclass References to the Current Class, below, for a
map to these subclasses.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
The general hierarchy of the Class 532 series has not been
followed and the above compounds include heterocyclic rings
when present together with the required elements of this
class. As can readily be seen, this class provides an
opportunity for searching certain types of heterocyclic
compounds as well as certain phosphorus organic compounds in
an alternative manner from that of Class 532.
Class 987 is a prototypical searching area developed under
the auspices of the Office of International Patent
Classification. In the past, search areas in the U.S.
classification system (Classes 976, 968, 984, and 930) have
been created utilizing the European Patent Office's (EPO)
classification of U.S. patents into their search and
retrieval system. Class 987 is significantly different from
those other classification areas in that a substantial number
of patents have been reviewed, a large number of subclasses
have been rearranged or merged, and definitions have been
written to describe the contents of each and every subclass.
In addition, the entire schedule has been presented in a
format which utilizes the first place rule of classification
which is the standard practice within the U.S. Patent
Classification System (USPCS).
The European Patent Classification System (EPCS) utilizes,
for the most part, the skeletal outline of the International
Patent Classification System (IPCS). To the broad IPCS, the
EPO has added additional classification areas and thereby has
created the EPCS. These are equatable to alpha subclasses in
the USPC. Both the IPCS and the EPCS utilize a last place
classification rule in C07F, which is the area of
classification equatable to new Class 987. The last place
rule requires locating the last subgroup in the
classification schedule which provides for the subject matter
to be classified. The U.S. classification system requires
placement in the first subclass for the subject matter to be
classified. As can readily be seen, these are substantially
different philosophies in the placement of documents. The
Class 987 schedule has been presented in a format which
negates this difference and therefor does not place any undue
burden upon the user to learn a new and different philosophy
of search.
Class 987 was created with the intention that Group 1200 of
the United States Patent and Office (USPTO) would soon have
the capability of searching patents utilizing all of the
enhanced aspects of the Automated Patent System; in
particular, the aspect relating to image searching. It is the
belief of Classification that the addition of Class 987 to
the searchable database can be of assistance at various times
in the examination process.
Although we believe that Class 987 will be of use to the
examination process, we are fully aware that the addition of
new search areas can create problems. One of the most obvious
questions that we have is the question of how examiners in
the EPO place documents. In the USPTO, we know that certain
rules exist between classes, that rules of superiority apply
between diverse types of subject matter (compound, method of
making, and method of using), that rules of comprehensiveness
apply between classes, and that all claims are classified,
and unclaimed subject matter is cross-referenced to
subclasses when it is determined to be useful.
In Class 987, we are relying on the placement techniques of
examiners in the EPO to locate U.S. patents. Although we
believe that EPO examiners follow our general rules in the
compound classes, we will not be completely certain until
Class 987 is tested and evaluated by the Corps. We hope to
conduct tests in concert with the Corps and will evaluate
fully the effectiveness of Class 987. If, at the end of the
evaluation period, we find that Class 987 does not meet the
requirements of the Corps, we will rethink whether we want to
retain the class.
The IPC and the EPC do not contain the types of definitions
associated with U.S. classes. This, in itself, does not in
any manner flaw their system. The titles and attendant notes
in the IPC are the full extent of the content of any
subgroup. When those tools are used together with the Guide
to the IPC (Volume 9), all of the tools to access and
retrieval are available. In the creation of this class,
definitions and notes have been written. Many of the
definitions are no more than the repeating of a subclass
title, while in other areas the definitions are much more
meaningful. The advantage, of course, to any definition is
that it hopefully conveys information that the creator of the
subclass thought might be useful to a user of the system and
that information is available even if the creator is no
longer available. We believe that the use of definitions
leads to consistency of patent placement.
Class 987 is available on the Automated Patent System (APS).
It is to be treated as any other class, with the proviso that
it cannot accept any original classifications and that any
search in the class is OPTIONAL. Patents can be added through
the use of the blue slip on allowance or by miscellaneous
transfer. Patents can be deleted from the files in the manner
currently in use.
Subject Matter Relating to Subclasses 300-304
The subject matter in subclasses 300-304 relates to EPCS
9/02A-9/02E. This is an ancillary search to subclasses 30-234
which include the subject matter of this search area, but
where no specific subclass has been identified in that
array.
Subject Matter Relating to Subclasses 350-368
The subject matter in subclasses 350-368 which encompasses
phosphorus containing a hetero ring containing at least one
nitrogen atom and no other hetero atom is equivalent in scope
to EPCS 9/65-9/65D3B. The aforementioned area in the EPCS
does not accept new patents and will be abolished in the
future. It has been replaced by subgroups 9/547 and
9/553-9/6533 which equate to new subclass 49 and subclasses
67-108. Although the scope of subject matter is the same, it
has been presented in a different classification scheme and
therefore movement of patents from one area to the other is
not easily done without reading the documents. The EPO is in
the process of reclassifying those patents into their new
reclassification scheme.
It is apparently the policy of the EPO to maintain two
searching areas as patents are being reclassified from an
abolished to a newly created subgroup. Since the abolished
area is not equivalent to the newly established areas, it has
been determined by the U.S. IPC group to concurrently present
the two classification systems. When the EPO has reclassified
all of the patents in the abolished area, the U.S. IPC group
will obtain that information and add those patents to
subclasses 49 and 67-108. At the same time, subclasses
350-368 will be abolished.

PHOSPHORUS CONTAINING COMPOUNDS (9/02; 9/06):
This subclass is indented under the class definition.
Subject matter drawn to organic compounds wherein phosphorus
is bonded either directly to a carbon or is indirectly bonded
to carbon only through non-ionic bonding.
(1) Note. In those subclasses which do not recite a valence
requirement, the P atom can be in any valence state.
(2) Note. Many of the subclasses are presented in a
structural formula recited format. The requirement for this
and the indented subclasses and in the absence to the
contrary is that a single moiety must exist in the compound
having the required structure. It is permissible that the
compound contain multiple moieties of the structure, although
in most instances this does not occur or special provision
has been made for those concepts by the creation of
subclasses requiring that feature.
(3) Note. The following rules apply to the use of structural
formulas or symbols in the schedule or definitions. A
structure such as:
(a) Hal-P-N or (Hal)-P-(N) indicates a direct bond between
the Hal and the P atom and a direct bond between the N atom
and the P atom. Other atoms may be bonded to the P and N
atoms. Atoms represented as being adjacent atoms to each
other by a hyphen indicates a direct bond between those
atoms. A hyphen may represent a single, double, or triple
bond.
(b) P=N or P(=N) indicates a direct double bond between the
P atom and the N atom. Other atoms may be bonded to the P and
N atoms.
(c) C=X or (C=X) represents a double bond between a carbon
atom and a chalcogen atom and where presented in a structure
indicates a direct bond between the C and the P atom, i.e.,
P-(C=X) indicates that a direct bond exists between the C
atom of the (C=X) group and the P atom.
(d) A single atom between parentheses (any atom) indicates a
direct, e.g., single, double, etc., bond between that atom
and a phosphorus atom, e.g., P-(O) indicates that the bond
between the P and the oxygen atom is direct and not through
another atom, and can be a single or double bond, and P-(C)
indicates a direct bond between P and C and the C can be of
any valence, etc.
(e) A single atom between parentheses (=any atom) indicates
a direct double bond between that atom and a phosphorus atom,
i.e., P-(=O) indicates that the bond between the P atom and
the oxygen atom is direct and must be a double bond.
(f) A moiety between parentheses indicates a direct bond
between the moiety and the P. If the moiety is (X-and any
other atom) where S is chalcogen, the direct bond is always
between the chalcogen and the P atom, unless there exists a
double bond between the X atom and the other required atom,
i.e., C=X in which case the direct bond is between the C and
the P atom.
(g) Chemical moieties shown without parenthesis with the
exception of moieties shown between quotation marks "--" (see
(h) below) cannot be bonded directly to the required P atom.
Furthermore, they may or may not be directly bonded to the
adjacent indicated atom.
(h) Chemical moieties shown between quotation marks "--"
indicates that an atom of the group, e.g., "ethylenic group,"
indicates that a carbon of the ethylenic group can be
directly or indirectly bonded to a P atom and "carbocyclic
ring" indicates that a carbon atom of the carbocyclic ring
can be directly or indirectly bonded to the P atom, etc.
(i) The term "Q" indicates a moiety containing an atom other
than C or H. The particular atom that is other than C or H
may or may not be bonded directly to the adjacent atom shown.
The bonding to the adjacent atom shown cannot be through a
phosphorus atom and requires a bond other than ionic.
(j) X used throughout the schedule and definitions is
limited to chalcogen, i.e., Oxygen (O), Sulfur (S), Selenium
(Se), and Tellurium (Te). For ease of readability, in many
instances, the chemical symbols for these elements have been
used.
(k) Phosphorus and its chemical symbol (P), carbon and its
chemical symbol (C), nitrogen and its chemical symbol (N),
and hydrogen and its chemical symbol (H) have been used
interchangeably throughout the schedule and definitions.
(l) Halogen or its abbreviated form (Hal) has been used
throughout the schedule or definitions to indicate the
presence of fluorine, chlorine, bromine, iodine, or astatine
atoms.
(m) The term "Z" indicates an atom other than C or H and
requires a direct non-ionic bond between the particular atom
that qualifies as Z and the adjacent atom indicated. The term
is meant to exclude classification on the inorganic portion
of an organic phosphorus containing compound. See (q) below.
(n) Chemical moieties shown within parentheses and an
asterisk (*). (1) (Aryl*) indicates that a carbon of the aryl
ring is bonded to the adjacent indicated atom shown. (2)
(Carbocyclic*) indicates a ring atom of the carbocyclic is
directly bonded to the adjacent indicated atom shown. (3)
(Ethylenic*) indicates a carbon of the unsaturated group
(double or triple bond) is directly bonded to the adjacent
atom shown. (4) (Cyano*) indicates a direct bond between the
carbon of the cyano group and the adjacent atom shown. (5)
(Acyl*) indicates a direct bond between the carbon of the
acyl group and the adjacent group shown.
(o) A moiety interposed between quotation marks "--"
indicates that it is alternative as to whether the named
group is directly or indirectly bonded to the P atom.
(p) Bonded directly or directly bonded indicates a non-ionic
bond between the two adjacent required atoms or moieties.
(q) Indirectly bonded or bonded indirectly indicates a
nondirect, non-ionic, linkage between nonadjacent atoms or
moieties. The terms are used to exclude classification on the
inorganic portion of a salt. When a compound is composed of
both an organic cation and an organic anion, then
classification on both of the organic moieties is
appropriate.
(4) Note. Organic acid salts, alcoholates, phenates,
chelates, or mercaptides are classified on the basis of the
organic portion of the compound that contains the phosphorus
atom. If both the anion and cation are organic, the entire
molecule is classified.
Subclass:
31
![[Patents]](../gifs/ps.gif)
Compound contains a ring which is devoid of a metal atom as
ring member and wherein the ring contains at least one atom
other than C, N, O, S, P, Se, or Te as a ring atom; e.g.,
boron, etc. (9/6596):
This subclass is indented under subclass 30. Subject matter
wherein a ring contains at least one atom other than C, N, O,
S, P, Se, or Te as ring members.
Subclass:
32
![[Patents]](../gifs/ps.gif)
Compound contains at least one atom of silicon or boron
(9/02G):
This subclass is indented under subclass 30. Subject matter
wherein the phosphorus containing compound contains at least
one atom of silicon or boron.
Subclass:
33
![[Patents]](../gifs/ps.gif)
Compound contains a ring which is devoid of a metal atom and
contains at least one P atom as ring member (9/6564; 9/6564V;
9/6568; 9/6568B; 9/6568C; 9/6568D; 9/6568E; 9/6568F):
This subclass is indented under subclass 30. Subject matter
wherein a phosphorus atom is part of a ring.
(1) Note. When phosphorus is a ring member, the traditional
definition of "heterocyclic" atom, as used throughout the
Class 532 series, is not met. Furthermore, the definition of
"heterocyclic," in the 532 series, requires the presence of a
carbon atom as a ring member, this is not the situation in
the EPC.
(2) Note. Whenever a ring atom is used throughout this and
its indented subclasses, it is meant to include only those
additional atoms that are in the same ring as is phosphorus.
An example of this is subclass 46, the oxygen ring atom must
be in the same ring with the P atom.
(3) Note. Extracyclic, as used in this and its indented
subclasses, is meant to include atoms not in the same ring as
phosphorus. A non-ring atom would include a heterocyclic ring
containing that atom in a ring devoid of phosphorus and other
ring atoms required by the title of the subclass.
Subclass:
