into a single physically isolated part of the device which
serves as an osmotic pump.

CROSS-REFERENCE ART COLLECTIONS
Electronic Cross Reference Art Collections 907-921 are
located in the schedule for Class 604 and have no definitions
associated with them.
A search in Class 604 Cross-Reference Art Collections 907-921
is an optional search. As patents from the U.S. and other
countries are published, the examiners in the European Patent
Office (EPO) receive them for placement in their search file,
the European Classification (ECLA) system, which is an
expansion of the International Patent Classification (IPC)
system. EPO examiners do not depend on the IPC printed on
the issued documents for placement into their system; they
reclassify each document again. All of the patents contained
in these cross-reference art collections have been classified
by EPO personnel.
These collections are available in electronic form only and
have no definitions associated with them. The most available
disclosure as to the types of documents contained in these
collections is given in any notes associated with the
titles.
As was previously mentioned, ECLA is an expansion of the IPC.
A number of classification areas have been added to the IPC
as a way of providing additional search areas to meet the
needs of the EPO examiners. These additional areas in the
ECLA schedule have alpha or alphanumeric characters added to
the traditional IPC notations.
Cross-Reference Art Collections 907-921 are, in general a
replication of subclasses in the A61 area of ECLA. At the
end of each cross-reference art collection, enclosed in
brackets, is the corresponding ECLA classification.
Patents (Cross-references only) can be added to these newly
created collections in the traditional manner, (i.e., blue
slips, miscellaneous transfer, or 14B). They can also be
deleted by submitting a copy of the document along with a
request to Classification.
