`stores digital audio content;
`
`U.S. Patent Application No. 2008/0194209 (“Haupt”)
`Haupt discloses a system comprising a mobile, digital audio player that stores digital audio content.
`
`“The spread of digitally compressed music for example in the form of MP3 files has risen greatly in
`recent years. Audio files are digitized and stored for example on a hard drive of a computer or the
`like. Thus, computers are increasingly used as music servers in the private sector and the computer
`is used for playing back the audio files stored thereon. Thus, it is possible to listen to music on a
`wired system and, if the computer has for example a radio interface, it is also possible to listen to
`music wirelessly or it is possible to provide for wireless transmission of the audio files or the audio
`signals. There are also music servers which are connected to the Internet and which provide audio
`files free or for a fee. A user can download the free or paid-for audio files on to his own computer by
`way of the Internet and can then listen to the downloaded audio files. By means of a mobile telephone
`or a mobile radio-enabled PDA, a user, on the basis of HSCSD, GPRS, UMTS or the like, can access
`the Internet and thus also download audio files of that kind. In that respect however it is found that
`there is the disadvantage that a large amount of data has to be transmitted at often an only low data
`transmission rate.
`
`A PDA or a notebook with a WLAN interface (IEEE 802.11) can also wirelessly access the Internet
`if the PDA or the network is within the transmission range of a WLAN access point. That is
`particularly advantageous in terms of the data transmission rate, in comparison with a mobile radio
`connection.”

`Abstract
`
`
`“A communication between the reproduction device WG and the public server OS or the private
`server PS is effected in particular by way of the Internet protocol. For that purpose the reproduction
`device has a suitable IP address IP-WG and the private and public servers also have corresponding
`IP addresses IP-PS, IP-OS. Mutual communication is thus effected on the basis of the respective IP
`addresses. That has in particular the advantage that the public or private server OS, PS can establish
`whether the receiver of the data is also actually the reproduction device WG. If the IP address of the
`data receiver is not in conformity with the IP address IP-WG of the reproduction device WG,
`communication of the respective data can be prevented. On the basis of the IP address it is also
`possible to trace back to whom the respective data were communicated. FIG. 2 shows a diagrammatic
`representation of a reproduction device of FIG. 1 in accordance with a first embodiment. In
`accordance with the first embodiment the reproduction device is in the form of a headphone unit with
`a WLAN interface. In other words, the headphone unit communicates directly on the basis of WLAN
`with an access point. Thus no further device is required for receiving the wirelessly transmitted
`signals. All necessary elements are integrated in the wireless headphone unit. This means that data
`can be wirelessly received by means of the wireless WLAN headphone unit if the headphone unit is
`in a transmission range of a WLAN access point.”

`
`
`“By means of the above-described wireless headphone unit with an integrated WLAN interface a
`person wearing such a headphone unit can listen to music whenever he is in the transmission range
`of a WLAN access point. High-quality audio reproduction is made possible by virtue of the high
`transmission rate in the case of WLAN. Furthermore, downloading of the corresponding data of the
`audio files or pieces of music to be reproduced can be substantially effected in real time so that only
`a very small intermediate memory or buffer is required in the headphone unit. Alternatively or in
`addition thereto the corresponding data can also be loaded at a higher speed and correspondingly
`stored in the intermediate memory or buffer. Thus the headphone unit can also be supplied with music
`and correspondingly reproduce same when the headphone unit is not in a transmission range of a

`
`If Koss argues that a POSA would not have interpreted Haupt to expressly disclose “an antenna for receiving
`wireless signals,” then implementing the headphone of unit of Haupt such that it sent and received wireless
`signals via an antenna would have been obvious as a POSA had several reasons to make such an
`implementation. For example, Haupt motivates and suggests use of an antenna because it discloses that
`data is transmitted and received wirelessly through IR, Bluetooth, and HF (Rezvani, [0041]), such wireless
`communications typically using an antenna. Second, it would have been a simple substitution of one known
`element (wireless communication) for another (wireless communication via an antenna) to obtain the
`predictable result of improved wireless communication. Third, it would have been use of a known technique
`(using an antenna) to a known device (a wireless headphone unit) ready for the improvement of improved
`wireless communication. At least the following prior art references disclose that “an antenna for receiving
`wireless signals” was common and conventional prior to the alleged invention of the ’025 Patent:
`
`
`“Once the piconet is configured and trusted relationships are established, receiver module 41 receives
`inbound RF signal 68 from base unit 16 via antenna 46. Bandpass filter 48 filters the received RF
`signal 68 which are subsequently amplified by low noise amplifier 50. Down converter 52 converts
`the filtered and amplified RF signal 68 into low intermediate frequency (IF) signal 70 based on a
`local oscillator 54. Low IF signals 70 may have a carrier frequency at DC ranging to a few

`
`
`“Both in accordance with the first and also the second embodiment a reproduction device, that is to

`a reproduction device can receive data wirelessly from an access point and then forward it again to
`further reproduction devices. That can take place either by a wired connection or wirelessly based on
`infrared, Bluetooth, HF or the like. Thus not just audio files but also audio streams can be
`simultaneously received by the reproduction device and correspondingly forwarded. In addition the
`reproduction device, that is to say the wireless headphone unit or the operating element, can provide
`for time control of reproduction to external reproduction devices in such a way that reproduction
`takes place synchronously. As an alternative thereto reproduction can be suitably delayed in the
`wireless headphone unit which is connected to the access point in order to achieve synchronous
`reproduction on all reproduction devices. Essentially therefore the wireless headphone unit or the
`operating element is in the form of a master, the further reproduction devices being implemented as
`the slave. Thus a wireless headphone unit or an operating element will occur as a local server and
`make the stored audio files available to other reproduction devices. Transmission of the data stored
`in the wireless headphone unit or the operating element can be effected either in real time or at an
`increased speed so that the other reproduction devices permit later or time-displaced reproduction in
`accordance with the size of their intermediate memory or buffer.”

`A POSA had reasons to have the wireless headphone unit of Haupt comprise a rechargeable battery for
`powering the wireless headphone assembly. First, a POSA would have understood that the unit requires
`electrical power in order to function, and to maintain the wireless nature of the unit a battery would been an
`obvious power source. A POSA would have wanted to offer the apparatus with a rechargeable battery as a
`more convenient method of providing electrical power than having to replace non-rechargeable batteries.
`Second, it would have been a simple substitution of one known element for another (a rechargeable battery)
`with a reasonable expectation of success because it merely required ordinary skill to incorporate a
`rechargeable battery in a wireless headphone unit. Third, it would have been obvious to try because
`rechargeable batteries were one of the most common of a finite number of known configurations for power
`supplies for wireless headphone units such as headphones and headsets (e.g., non-rechargeable batteries).
`At least the following prior art references disclose the use of rechargeable batteries for headsets/headphones
`as a common and conventional design prior to the alleged invention of the ’025 Patent:

`Claim
`utterances by a user of the
`headphone assembly; and
`
`[1(i)] a remote, network-connected
`server that is in wireless
`communication with the mobile,
`digital audio player;
`
`U.S. Patent Application No. 2008/0194209 (“Haupt”)
`“The invention also concerns a wireless microphone comprising an electroacoustic transducer for
`recording audio signals and a transmitting/receiving unit for wirelessly transmitting the recorded
`audio signals. The wireless microphone also has a network identification unit for storing a network
`identification of the wireless microphone. The transmitting/receiving unit further serves to transmit
`the network identification of the microphone, which is stored in the network identification unit. There
`is thus provided a wireless microphone which no longer merely represents just a passive transmitter
`of audio signals but is now implemented in the form of an active network element and thus provides
`an Internet service.”
`

`
`
`“As the data stored on a private server PS or a public server OS can involve a very large amount of
`data, it is necessary to ensure that a user can navigate within those data. For that purpose for example
`a program is implemented on the server, which sorts and suitably predefines the data on the server.
`As soon as the wireless headphone unit then forms a connection with that server the corresponding
`audio files are communicated to the wireless headphone unit so that it can play the files back.
`Navigation can be effected either by way of selection keys or buttons on the headphone unit or by
`way of speech input by means of an additional microphone. In other words, by means of the selection
`keys and the speech commands, a user can control a corresponding navigation program on the server.
`Alternatively the navigation program can be a component part of the headphone unit, in which case
`then the commands are so translated that the server service understands them and executes the
`corresponding commands. An operating element with a display can either be integrated in the
`headphone unit or can be in the form of an external device. Thu
