GENERAL SUMMARY OF SUBJECT MATTER WITHIN THIS CLASS
A. The following types of claimed subject matter are proper
for this class.
1. A claim drawn to a process of making a photopolymerizable
composition of reactant X plus photoiniator or photosensitizer.
2. A claim drawn to a photopolymerizable composition of reactant
X plus photoinitiator or photosensitizer.
3. A claim drawn to a process of irradiating reactant X with
or without a photoinitiator or photosensitizer being present.
4. A claim drawn to a photopolymerizable composition of reactant
X plus photoinitiator or photosensitizer and any other material
(e.g., filler, solvent, etc.).
In the types of subject matter (1-4 above), reactant X can
be a monomer, low molecular weight condensation or addition product,
or solid polymer. The sole proviso is that the final product be
a solid polymer as is required by the Class 520 Series of classes.
When a claim so expressly states, a monomer or polymer is considered
to be a photoinitiator or photosensitizer.
The recitation of a specified amount of photoinitiator or photosensitizer
is unnecessary for purposes of classification in this class.
B. To be properly classified in this class, a compound must
have a photoinitiator or photosensitizer claimed in addition to
the monomer to be polymerized or the polymer to be treated. For
example, a claim drawn to a photopolymerizable composition comprising
an ethylenically unsaturated monomer plus a photoinitiator is properly
classified herein, whereas a claim drawn to a substituted benzophenone
autopolymerizable composition is not properly classifiable in this
class. The requirement for proper classification is separateness
of monomer or polymer and photoinitiator or phtosensitizer. A material
described as being both a photoinitiator or photosenitizer and a
reactant and a separate monomer or solid polymer is a proper composition
for subclass 1 of this class. Products which are the result of a
wave energy process are normally excluded from this class and are
classified in other areas of the 520 Series of clases. An exception
to this would be a situation wherein a further wave energy step
is contemplated and the formed product is an admixture with a photoinitiator or
photosensitizer.
A claim drawn to a specific photoinitiator such as a benzophenone
with no mention in the claim of the functionality of the substance
as a photoinitiator is classified herein if the disclosure teaches
the use of benzophenone as a photoinitiator.
A combination of chemical process steps not involving wave
energy followed by a subsequent chemical reaction involving wave
energy is classified herein provided the product is proper subject
matter for the Class 520 Series.
Claims drawn to the utilization of wave energy to initiate
a chemical reaction followed by the application of heat are proper
for this class. For example, a process of partially polymerizing
a monomer of methylfluoroacrylate by wave energy followed by treatment
with heat to complete the polymerization is proper for the Class
520 Series.
The utilization of wave energy to induce a chemical reaction
which thereby proceeds without the assistance of further wave energy
is considered to be proper subject matter for this class; for example,
a claim drawn to utilizing wave energy to activate a peroxide in
order to generate free radicals, wherein the free radicals promote a
chemical reaction is classified herein.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
The step in a process claim utilizing wave energy is the proper
basis for classification purposes. For example:
A. A claim drawn to processes of polymerixing ethylene in
the presence of carbon black (DNRM) by wave energy is properly classified
in subclass 71, whereas a claim drawn to polymerizing ethylene in
the presence of wave energy followed by treating the product with
carbon black (DNRM) is properly classified in subclass 189.
B. A claim drawn to treating polyacrylonitrile with vinyl
chloride in the presence of energy is properly classified in subclass
124, whereas a claim drawn to treating a graft polyacrylonitrile-vinyl
chloride copolymer with wave energy is properly classified in subclass
149.
C. A claim drawn to the process of making polyethylene by
polymerizing ethylene in the presence of wave energy followed by
chemically treating said product with halogen (with no wave energy
present) would be classified in subclass 189, whereas a claim drawn
to the process of reacting polyethylene with halogen in the presence
of wave energy following by the addition of carbon black would be
classified in subclass 133.
Classification in Class 522 is on the first solid polymer prepared.
For instance, a process of chemically modifying a solid polymer
derived from ethylene only, by sulfonating, (nonwave energy process)
and then subsequently reacting said sulfonated polymer with elemental
halogen using wave energy is proper in subclass 133, since the first
solid polymer prepared is polyethylene. Subclass 132 does provide
for a halogenated polymer which is subsequently reacted in that
the language of the subclass is "contains" rather
than "derived". In subclass 154 the language
is "derived" and therefore if a halogenated polyethylene
is treated using wave energy classification in subclass 161 is proper
since the first solid polymer is prepared from ethylene.
A process of treating a solid polymer with wave energy followed
by the addition of a chemical reactant is presumed, in the absence
to the contrary to proceed entirely by wave energy and is classified
in this class subclasses 113-147; however, a process of treating
an irradiated polymer with a chemical reactant is properly classified in
Class 525. Additionally a process of treating a reactant with wave
energy followed by adding a solid polymer and reacting therewith
is presumed in the absence of information to the contrary to proceed
entirely by wave energy and is classified in this class.
A process of treating a preirradiated polymer (no wave energy
process step recited) is properly classified in Classes 523-525
when no further wave energy step is claimed. For example, (1) a
process of a mixed preirradiated polymer with a DNRM is properly
classified in Class 524, and (2) a process for treating a preirradiated polymer
with an ethylenic monomer is properly classified in Class 525.
The combination of Class 204 wave energy step followed by
a Class 522 wave energy step is classified herein; for example,
a claim drawn to a process of utilizing wave energy to synthesize
a monomer which is subsequently polymerized in the presence of wave
energy is classified herein.
The utilization of wave energy to generate heat, whereby the
heat generates or induces a chemical reaction is not considrered
to be "a chemical reaction induced by wave energy" and
thus is not proper subject matter for Class 522. The process, however,
is proper in for the Class 520 Series if a solid polymer is produced.
Class 204, Chemistry: Electrical and Wave Energy, appropriate
subclasses provide for producing a product of the type provided
for in the Class 520 Series by other than a wave energy process.
Class 204 is superior to the Class 520 Series; therefore, a patent
claiming in the alternative a process of preparing an organic compound and
a synthetic resin or natural rubber in the presence of wave energy
is classified for original purposes in Class 204 and cross-referenced
to the Class 520 Series. In the situation where an alternative
process claim is presented along with a specific process claim to
the synthetic resin or natural rubber, there is no specific claim
to the nonsynthetic resin or nonnatural rubber species, and the process
is directed to wave energy, the same rule of original patent placement
applies. Any process step involving electrolysis, an electric current,
electro-osmosis, electrophoresis, an electrostatic field, an electrical discharge,
or a magnetic field and also involving the preparing or treating
of a synthetic resin or natural rubber is proper for Class 204,
even when the wave energy step involved is subsequent to a Class
204 step. Combinations of chemical process steps provided for by
the Class 520 Series (other than those involving wave energy) and
process steps falling within the definition of Class 204 are proper
for Class 204 when the Class 520 Series process steps are preparatory
to the Class 204 process steps and are proper for the Class 520
Series when the Class 204 process steps are preparatory to the Class
520 Series process steps.
Class 430, Radiation Imagery Chemistry: Process, Composition,
or Product Thereof, appropriate subclasses provide for radiation
sensitive compositions and elements and for processes of exposing
said composition or elements to wave energy using an imagewise exposure
technique. Class 522 provides for compositions and processes involving
use of radiation for polymerizing compositions having a photoinitiator
or photosensitizer or for modifying polymers. Class 430 provides
for compositions solely disclosed, or claimed for radiation imagery.
Compositions and processes not involving radiation imagery, or
disclosing both a radiation imagery use, and another use are placed
in Class 522 and cross-referenced to Class 430. Also, see Class 430
classification line for compositions with art claimed, especially,
multiple use (Class 430, III A 2a).
SECTION III - SUBCLASS REFERENCES TO THE CURRENT CLASS
Schedule Outline of Class 522: The schedule is divided into
a number of parts, each of which is distinct and provides for different
types of subject matter. The following SEARCH THIS CLASS, SUBCLASS
is a breakdown of the major areas and indicates the type of subject
matter provided therein.
through 5, for manipulative process areas which
provide for certain designated processes of preparing or treating
a polymer or compositions therefore. This area has no generic subclass
and therefore documents not covered under the ambit of this subclass
range are classified below on some other basis.
through 70, for the specified rate-affecting material
area which provides for processes of preparing or treating polymers
or compositions therefor wherein a rate-affecting material is utilized
simultaneously with the wave energy and wherein at least one rate-affecting
material is designated by at least one atom, e.g., a nitrogen-containing
photoinitiator, etc. This area is further subdiveded into the following
six subclass ranges.
through 10, for either (1) at least two rate-affecting
material containing a keto group which is not part of a ring (e.g.,
benzophenone, etc.) or (ii) the combination of one rate-affecting
material containing a keto group which is not part of a ring plus
a rate-affecting material referred to as a "photoinitiator
or photosensitizer". The basic premise of these subclasses
is that a rate-affecting material identified as a "photoinitiator
or photosensitizer" is to be equated with a rate-affecting
material containing a keto group wherein the keto group is not part
of a ring.
for the combination of a rate-affecting material containing
a keto group not part of a ring plus a broadly claimed rate-affecting
material, other than "photoinitiator or photosensitizer",
e.g., the combination of a benzophenone and a curing catalyst would
be proper for this subclass, etc.
through 23, for the combination of either (1) a rate-affecting
material containing a keto group not part of a ring plus a rate-affecting
material wherein at least one atom is designated; or (2) a rate-affecting
material referred to as a "photoinitiator or photosensitizer" plus
a rate-affecting material wherein at least one atom is designated.
The basis of classification in these subclasses is with the latter
ingredient of the aforementioned combinations (1) and (2).
through 30, for the combination of two or more rate-affecting
materials neither one of which contains a keto group not part of
a ring. The basis of classification in these subclasses is with
the first appearing rate-affecting material provided in the schedule
hierarchy.
through 86, for the designated nonreactant areas
provide for processes of preparing or treating polymers or compositions
therefor, wherein a designated nonreactant material is present
when the wave energy is applied.
through 108, specifically for proteins and carbohydrates
as reactants and for treating a terminally unsaturated polyurethane,
ethylenically unsaturated siloxane, polysiloxane, polyester or polypoxide
derivative.
Bleaching and Dyeing; Fluid Treatment and Chemical
Modification of Textiles and Fibers, appropriate subclasses for bleaching or dyeing; fluid treatment
and chemical modification of textiles and fibers wherein use is
made of electrical radiant or wave energy other than electrolysis,
for which see Class 205,
subclasses 689+ .
Electrolysis: Processes, Compositions Used Therein,
Methods of Preparing the Compositions,
subclasses 689+ , for chemical modification of textiles and fibers
using electrolysis.
Coating Processes, appropriate subclassesfor processes of coating a substrate followed by curing
the coating using electrical or wave energy. Included in Class
427 are processes of producing a coating by application of wave energy
chemistry to a base material which supplies a part or all of the
coating, e.g., conversion of the surface of a polymeric material
to produce a film thereon by the application of wave energy, etc.
through 528, Synthetic Resins or Natural Rubbers, appropriate subclasses for processes of preparing
and treating polymers by chemical and physical means.
