1. A method for minimizing
feedback responses in an
ARQ protocol, comprising
the steps of:
sending a plurality of first
data units over a
communication link;
receiving said plurality of
first data units; and
responsive to the receiving
step, constructing a message
field for a second data unit,
said message field including
a type identifier field and at
least one of a sequence
number field, a length field,
and a content field.
US6581176 (Method for transmitting control frames
and user data frames in mobile radio communication
system); Priority date: Aug. 20, 1998
US6581176 discloses a “transmitting station” that
sends user data frames to a “receiving station” over a
“radio section between a receiving station and the
transmitting station.” US6581176 discloses a
“receiving station” that receives user data frames
from the “transmitting station.”
US6581176 discloses an “RLP NAK” message that
includes a field NAK_TYPE that identifies whether
the message identifies a range of sequence numbers
or uses a bitmap. If the value of NAK_TYPE is “00,”
the RLP NAK message includes two fields—FIRST
and LAST—with “the 12-bit sequence number of the
first data frame for which a retransmission is
required,” and “the 12-bit number of the last data
frame for which a retransmission is required,”
respectively. If the value of NAK_TYPE is “01,” the
RLP NAK message includes a field
NAK_MAP_SEQ with “the 12-bit sequence number
of the first data frame in this NAK Map for which
retransmission is requested.” The RLP NAK

message includes a type identifier field
(NAK_TYPE), and a sequence number field
(FIRST, LAST, or NAK_MAP_SEQ). US6581176
discloses the limitation whether “type identifier
field” is construed to mean “a field of a message that
identifies the type of that message,” or, in the
alternative, to mean any type of data.
Claims 1, 2, 4, 6, 8, 15, 22, 25, 26, 29, 32, 34,
45, 46, 49, 52, and 54 are unpatentable under 35
U.S.C. § 102(b) as anticipated by US6581176.

Claims 1-6
Claim 1. A communication
station comprising:
a processor for arranging
information for
transmission including
providing at least one first
field in which payload
information is disposed and
providing at least one
second field, separate from
said first field, which
includes a service type
identifier which identifies a
US5488610 (Communication system); Priority date:
Aug. 26, 1993
US5488610 describes a multiplexer for use in a
system for transmitting more than one type of data,
e.g., voice and data. Figure 2 is a block diagram
showing the main components of communication
system 10 of the invention. Controller 18 comprises
processor 19, storage means 20,
multiplexer/demultiplexer 22, voice coder/decoder
24, and line interface 27. Communication system 10
can be used to share voice and visual data with
another user of a similar system. Multiplexer 22
multiplexes the voice and data signals, adds
synchronization information, and transmits the
composite signal to the physical layer high speed

modem (V32bis) connected to the Public Switched
Telephone Network (PSTN) or a GSM mobile
network). The composite signal is organized into
frames each containing a header and one or more
complete voice frames and/or other non-voice data.
The content of each frame is determined by the
applications and may change during the call. Figures
5a to 5g show the structures of some possible frames.
In Figures 5a to 5g, “H” is a header field that
identifies the frame type, which is used to identify
the contents of a frame.
Under the direction of processor 19, multiplexer 22
arranges voice and non-voice data for transmission
in frames. A frame may contain at least a field V
(voice) or D (non-voice data) in which payload
information is disposed. A frame also contains a
separate field, H (header), that identifies the frame
type—i.e., the type of payload information—as voice
only, data only, or voice and data.
Claims 1–6 are unpatentable under 35 U.S.C. §
102(b) as anticipated by US5488610.
US5541662 (Content programmer control of video
and data display using associated data); Priority date:

US5541662 describes an interactive video system

that processes a video data stream and an associated
data stream corresponding to the video data stream.
US5541662 is focused on a receiver, while the
claims are to a transmitting device. However, one of
ordinary skill in the art would have understood that
the US5541662 implicitly teaches a communication
station for transmitting packetized digital data
streams, including the three types of payload, in
US5541662. Therefore it would have been obvious
to provide a transmitter for sending the type of data
that US5541662 receives.
Claims 1–6 are unpatentable under 35 U.S.C. §
103(a) as obvious over US5541662.

US5377221 does not disclose assigning a unique
seed value to a node as required by claim 5’s
limitation (a). Nor does it disclose randomizing a list
of available node channels using a deterministic
pseudo-random number generator seeded with said
seed value (referring to the unique seed value) as
required by claim 5’s limitation (d). In addition,
US5377221 does not disclose the channel punchout
mask as required by claim 5’s limitations (b) and (c).

Claim 21. A method for
providing a promotional

terminal over a mobile
network, the method
comprising:

enabled mobile terminal

The claimed invention is directed to an abstract idea,
specifically, the abstract idea of receiving
information and providing services or advertisements
based on that information. The preambles and all
claim limitations of both claims support this abstract
idea, and the patent repeatedly discloses that the
invention is directed to providing services or
advertisements. The identified abstract idea is a
fundamental building block of economics, similar in
nature to the abstract idea of hedging claimed in
Bilski and intermediated settlement claimed in Alice.
The claimed subject matter does not do anything
more than simply instruct the practitioner to
implement the abstract idea of gathering,
authenticating, and transmitting data and services on

authenticating the SRC
device information; and
in response to
authenticating the SRC
device information,
providing the promotional
mobile service to the SRC-
enabled mobile terminal
over the mobile network on
a time-limited basis.
Claim 22. A method for
receiving an advertisement
over a mobile network, the
method comprising:
acquiring short range
communication (SRC)
device information from a
SRC device using an SRC-
enabled mobile terminal;
providing the SRC device
information to a mobile
service provider over the
mobile network; and
receiving the advertisement

communication elements of the claims add enough to
make the claims patentable, Patent Owner fails to
identify any language in the claims or the
Specification demonstrating that the generic
communication systems function in an
unconventional manner. Instead, through the bare
recitation of the steps of “receiving,” “acquiring,”
“authenticating,” and “providing,” the claims are
“specified at a high level of generality,” which the
Federal Circuit has found to be “insufficient to
supply an ‘inventive concept.’” Ultramercial, 772
