Apple Computer Inc. v. Burst.com, Inc. Doc. 72 Att. 2 Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 1 of 31 "time compression," which is more specific than data compression, there are still a range of very different structures that could be used. The Roberts patent (U.S. Patent No. 2,987,614) cited by the Burst patents provides one example; the Haskell patent (U.S. Patent No. 4,300,161) provides another very different example. One of ordinary skill in the art would look to the specification to determine what structures, if any, disclosed by Burst are clearly linked and are necessary to perform the function performed by the "compression means" of "compressing said audiolvideo source information into a time compressed representation thereof." This exercise must be performed for each patent individually. a. '995 patent STRUCTURE FOR COMPRESSION The only structure in the '995 patent that performs compression of any kind is a fax compression chip, AMD 7971, from Advanced Micro Devices. See Exh. B ['995 patent] at 4:63-5:8 ("Compression of the digital data defining a video frame and the reverse process (decompression) are accomplished by compressor/decompressor 26. . . . One example of an appropriate compression/decompression circuit on a single integrated circuit is the AMD (Advanced Micro Devices) 7971."). However, that fax compression chip operated by compressing only two-tone images for facsimile transmission. Interestingly, the AMD 7971 would not have worked to compress and decompress color images or full motion video. It could not have compressed audio signals. The AMD 7971 could only have performed a limited type of data compression - compressing and decompressing two-tone images, typically facsimile text, and is not linked to a function of "time compression." No other structures are linked to a compression function in the '995 patent. While the patent suggests that certain "algorithms" could be used to perform data compression, this disclosure does not link a structure to the "time compression" function. See id. at 4:65-5:2 ("Various algorithms may be employed in the compression process which enable the representation of a series of numbers by a reduced number of digits. As an example, compression algorithms like CCITT Group IV may be used."). First, the patent discloses that algorithms may II EXPERT REPORT OF JOEL HALPERN RE: CLAM CONSTRUCTION Civ.

There is no disclosure that a compression algorithm would be run on a general purpose computer as software. The patent specifically refers to the compression as occurring in compressor/decompressor 26, which is specifically identified as a separate structure from CPU 28, and CPU 31. Neither CPU 28 nor CPU 31 is ever linked to the function of compression or decompression. Second, the general purpose processors that existed in the 1988 time period could not perform compression in real time by running algorithms in software.' Third, the only algorithms disclosed are algorithms for data compression and not time compression - the algorithms "enable the representation of a series of numbers by a reduced number of digits" and nothing more. Id. The patent does not disclose the use of general purpose processors for performing compression. The patent does disclose general purpose processors that are dedicated to other functions, but are not used for compression. Compression is handled solely by the AMD 7971 compression chip, which is a component of the video control unit ("VCU"). There is a general The general purpose microprocessors available at the time of the Burst patents were not capable of performing the data compression disclosed in the patents in real time. The fastest generallyavailable microprocessor of the time was the Intel 386DX. The 386DX was capable of 11.4 See Exh. S [Datasheet for Intel 3 8 6 T M ~ ~ million instructions per second (MIPS). Microprocessor, 32-bit CHMOS Microprocessor with Integrated Memory Management (December 1995)l. The data compression required by the patent required far more than 11.4 MIPS to be performed in real time. The source information of the patents contained 2.7 million pixels per second (300X300 pixels times 30 frames per second). Successful compression of 2.7 million pixels per second at a maximum processor speed of 11.4 MIPS would require compression to be accomplished with no more than four instructions per pixel per second. That is not enough instructions per pixel to allow for data compression as described in the patent. Compression requires a series of instructions for each pixel. These include, for example, instructions for fetching the pixel data, comparing pixel values, branching based on these comparisons, incrementing counters, shift instructions and Boolean instructions to create compressed representations, storing compressed representations, and branching to repeat the process for the next pixel. Algorithms such as the CCITT Group IV fax compression algorithm cited in the patent require significantly more complex computations to produce the compressed data. Even four instructions per pixel would require processing power of 10.8 MIPS, nearly the full capacity of the Intel 386DX. Because compression required many more than four instructions per pixel, compression of the type described in the patent could not be accomplished in real time by the general purpose microprocessors of the day. The fact that real-time compression through general purpose microprocessors was not available at the time the patents were filed is confirmed by a 1988 IEEE article by Luther about Intel's DVI compression technology. According to Luther, even a supercomputer with 64 processors required three seconds to compress a single video frame, whereas the Burst patents require processing to occur in one-thirtieth of a second. See Exh. T [Luther, "You are there ...and in control," IEEE Spectrum, pp. 45-50 (September 1988)l. II EXPERT REPORT OF JOEL HALPERN RE: CLAIM CONSTRUCTION Civ. Case No. 3:06-CV-00019 (MHP) 30 Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 3 of 31 purpose CPU 28 that c'controls the digitization process of VCU 12." See Exh. B ['995 patent] at 5:46-49 ("CPU 28 works with controller 27 to control and communicate with the other elements of the VCU."). This means that the CPU serves a function of controlling the compression chip. The CPU does not itself perform the function of compressing and does not run any compression software. Because the function is "compressing" and not "controlling the compression," this CPU is not clearly linked to the function of compressing. STRUCTURE FOR TIME COMPRESSION There is no structure disclosed in the '995 patent that is linked to the function of compressing source information into a "time compressed" representation. As discussed above in Section H of my report, "time compression" is distinct from "data compression." While structure for doing data compression is disclosed in the '995 patent (AMD 7971 fax compression chip), this is not structure for doing time compression. Thus, there is no structure disclosed in the '995 patent that is clearly linked to the "time compression" function. This is not surprising. The original claims of the '995 patent as filed either did not require compression or were directed to garden variety data compression. See Exh. N ['995 File History] at APBU 38 (Original claims 1, 4). The claims were amended to require "time compression" only after the original claims had been rejected over the prior art, which also taught data compression. While the disclosure of a single means for data compression might have supported claims directed to data compression, the patent as issued lacks support for claims limited to time compression. b. '705 patent As with the '995 patent, there is no structure disclosed in the '705 patent that is linked to the function of compressing source information into a "time compressed" representation. Moreover, the only structure related to compression of any kind in the '995 patent, the AMD 7971 fax compression chip, is not present in the specification of the '705 patent. The '705 patent was filed as a continuation-in-part of the application that led to the '995 patent. The specifications of the two patents share much of the same text, with the '705 typically adding further disclosure. However, the text that described the AMD 7971 chip was removed before EXPERT REPORT OF JOEL HALPERN RE: CLAIM CONSTRUCTION Civ. Case No. 3:06-CV-00019(MHP) 31 Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 4 of 31 filing of the continuation-in-part application that led to the '705 patent. Thus, there is no structure in the '705 patent linked to a compression function of any kind, let alone "time compression." As with the '995 patent, no other structures are linked to any compression function in the '705 patent. The patent discloses that compression and decompression are performed by " c ~ r n p r e ~ ~ ~ r / d e c ~ m p r26,"s o r e s which is an undefined block in a flow chart. Block 26 would not be recognized as a structure linked to the "time compression" function by one of ordinary skill in the art. While the patent suggests that certain "algorithms" could be used to perform data compression, this disclosure does not link a structure to the "time compression" function. See Exh. E ['705 patent] at 5:ll-15 ("Various algorithms may be employed in the compression process which enable the representation of a series of numbers by a reduced number of digits. As an example, compression algorithms like CCITT Group IV may be used."). First, these algorithms would not be understood by one of skill in the art as structures. There is no disclosure that a compression algorithm would be run on a general purpose computer as software. Second, the only algorithms disclosed are algorithms for data compression and not time compression - the algorithms "enable the representation of a series of numbers by a reduced number of digits" and nothing more. Id. c. '932 patent As with the '705 patent, there is no structure disclosed in the '932 patent that is linked to the function of compressing source information into a "time compressed" representation. The '932 patent shares the same specification with the '705 patent and does not include the AMD 7971 fax compression chip that was disclosed in the '995 patent but removed from the continuation-in-part application that led to the '932 and '705 patents. Thus, there is no structure in the '705 patent linked to a compression function of any kind, let alone "time compression." As with the '705 patent, no other structures are linked to any compression function in the '932 patent. The patent discloses that compression and decompression are performed by " c ~ m p r e ~ ~ ~ r / d e c ~ r n p r26," o r e s s which is an undefined block in a flow chart.

While the patent suggests that certain "algorithms" could be used to perform data compression, this disclosure does not link a structure to the "time compression" function. See Exh. C ['932 patent] at 5:18-23 ("Various algorithms may be employed in the compression process which enable the representation of a series of numbers by a reduced number of digits.

"random access storage means representation" . ..for storing the time compressed 1. Opinion A person of ordinary skill in the art in the 1988-1989 timeframe would not recognize "random access storage means" as referring to a particular structure or class of structures. There is no structure clearly linked to the function of storing a "time compressed representation" because the specifications of the Burst patents do not contain any reference to time compression or storing time compressed representations. The structures that are clearly linked and are necessary to perform the function of storing the data compressed versions of source information are DRAM, SRAM, CMOS memory, or optical disc memory. 2. Bases and Reasons One of ordinary skill in the art would have understood that the phrase "random access storage means . . . for storing the time compressed representation" did not connote a particular structure. The phrase "random access storage" is generic and functional language - it would not identify to one of skill in the art which structures, for purposes of the claims, perform the "storage" function. There are a wide variety of very different classes of structures that provide random access storage, including magnetic and optical disks, RAM, and ROM. The fact that "storage" is essentially generic and lacking in definite structure is shown in technical dictionaries. See, e.g., Exh. Q [MCGRAW-HILL DICTIONARY SCIENTIFIC OF AND TECHNICAL TERMS, T ED.(1989)l (storage: "Any device that can accept, retain, and read ~ H back one or more times; the means of storing data may be chemical, electrical, magnetic, mechanical, or sonic."). The definition of storage as encompassing any device demonstrates that "storage" is purely functional language. Likewise, one of ordinary skill in the art would have understood "random access storage" as being functional, it is simply a narrower function than any storage that excludes some classes of structures, such as tape drives.

'995 patent The specification of the '995 patent discloses several structures that are linked to the function of storing. See Exh.

These four types of memory, DRAM, SRAM, CMOS memory, or optical disc memory, are the only structures clearly linked and are necessary to perform the function of storing.

"storage means. . .for storing said digital time compressed representation" 1. Opinion A person of ordinary skill in the art in the 1988-1989 timeframe would not recognize "storage means" as referring to a particular structure or class of structures. There is no structure clearly linked to the function of storing a "time compressed representation," because the specifications of the Burst patents do not contain any reference to time compression or storing time compressed representations. The structures that are clearly linked and are necessary to perform the function of storing the digital data compressed representation are DRAM, SRAM, CMOS memory, optical disc memory, bubble memory, magnetic disk, or digital paper. 2. Bases and Reasons One of ordinary skill in the art would have understood that the phrase "storage means . . . for storing said digital time compressed representation" did not connote a particular structure. The term "storage" is generic and functional language - it would not identify to one of skill in the art which structures, for purposes of the claims, perform the "storage" function.

The definition of storage as encompassing g device demonstrates that "storage" is purely functional language. Thus, one of ordinary skill in the art would have understood that Burst's proposed construction that "storage means" implies sufficient structure on its own is incorrect. To determine what structures disclosed in the patents are both clearly linked and are necessary to perform the function performed by the "storage means" of "storing said digital time compressed representation," I have reviewed each patent individually.

"output means for receiving. ,for transmission away from said audiolvideo transceiver apparatus" ... . 1. Opinion A person of ordinary skill in the art in the 1988-1989 timeframe would not recognize "output means" as referring to a particular structure or class of structures. For the '995 patent, the structure that is clearly linked and is necessary to perform the function of receiving time compressed audiolvisual source information and transmitting that information away from the transceiver apparatus is fiber optic port 18 that delivers audiolvideo signals to a fiber optic telephone line. For the '932 patent, the structure that is clearly linked and are necessary to perform the function of receiving time compressed audiolvideo source information and transmitting that information away from the transceiver apparatus is a point-to-point or satellite microwave transceiver. 2. Bases and Reasons One of ordinary skill in the art would have understood that the phrase "output means . . . for receiving . . . for transmission away from said audiolvideo transceiver apparatus" did not connote a particular structure. The term "output" would have been understood as generic and functional language - it would not identify to one of skill in the art which structures, for purposes of the claims, perform the "output" function. The fact that "output" is essentially generic and lacking in definite structure is DICTIONARY SCIENTIFIC OF shown in technical dictionaries. See, e.g., Exh. Q [MCGRAW-HILL AND TECHNICAL TERMS,4TH ED. (1989)l (input/output device: "A unit that accepts new data, sends it into the computer for processing . . . ."). A "unit" is even more generic than an "output" - the definition confirms that an input device is a "unit" that performs the function of outputting Thus, one of ordinary skill in the art would have understood that Burst's proposed data. construction that "output means" implies sufficient structure on its own to render construction of the phrase unnecessary is incorrect.

Case No. 3:06-CV-00019 (MHP) Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 11 of 31 To determine what structures disclosed in the patents are both clearly linked and are necessary to perform the functions performed by the "output means" of "receiving" the time compressed representation and "transmission away from said audiolvideo transceiver apparatus," I have reviewed each patent individually. a. '995 patent The specification of the '995 patent discloses only one structure that is linked to the function of receiving time compressed source information and transmitting it away from the transceiver apparatus. The fiber optic port 18 is described as being capable of receiving source information See Exh. B ['995 patent] at 7:45-55 ("Fiber optic port 18 incorporates a fiber optic transceiverlreceiver. . . . The incorporation of fiber optic port 18 in the VCR-ET provides a capability for receiving audiolvideo signals from or delivering audiolvideo signals to the fiber optic line such as a fiber optic telephone line."). The patent discloses that the VCR-ET can receive source information as a time compressed representation through the fiber optic port. Id. at 7:58-64 ("The VCR-ET can receive a video program at an accelerated rate via fiber optic port 18, e.g., from a variety of sources. For example - a video program may be communicated at an accelerated rate from the first VCR-ET to a second VCR-ET in less time than it would take to view the program."). This disclosure that the fiber optic port 18 enables faster than real time transmission and receipt of video programs is what clearly links the fiber optic port 18 to the function of receiving and sending time compressed data. By contrast, the patent teaches that the other output structure, a conventional modem and phone line, is not capable of transmitting time compressed data faster than real time. Id. at 8:50-57 ("[Tlhe time required to communicate a video program over a conventional phone line may exceed the time it takes to view the program."); id. at 9:65-68 ("[Elven compressed data may require more time to transmit over conventional phone lines than it would take to view the actual video program."). Thus, the modem and conventional phone line combination is not clearly linked to the function of receiving and transmitting time compressed information.

'932 patent As I discussed above in the context of the "input means," the file history of the '932 patent makes clear that only one set of structures is linked and is necessary to perform the receiving and transmitting function: microwave transceivers. During prosecution of the '932 patent, Burst attempted to overcome a rejection by adding new claims directed at an apparatus centered around a microwave transceiver. See Exh. R ['932 File History] at APBU 216 ("New claims 26-29 [present claims 1-41 are directed to an audiolvideo transceiver having the ability to receive audiolvideo source information over a microwave link."). Burst specified that new claim 26 (now claim 1) was directed to an apparatus that included "input and output means comprising microwave transceiver means" and that new claims 27-29 (now claims 2-4) "call for substantially the same structure recited above" with additional limitations to the memory element. See id. at APBU 232. One of skill in the art would understand Burst's statements during prosecution concerning the amendment of the claims to limit the structure associated with the "output means" to a microwave transceiver. Per the specification of the '932 patent, the microwave transceiver can be either a point-to-point or satellite transceiver. See id. at 11:53-12: 11.

'995 patent, claim 2 The specification of the '995 patent discloses that a combination of several structures are necessary to perform the function of "editing the time compressed representation . . . and for restoring the edited time compressed representation." The primary function of "editing" by manipulating the stored time compressed data is handled by a control unit with several components. See Exh. B ['995 patent] at 6:23-29 ("Digital Control Unit (DCU) 14 comprises a CPU (Central Processor Unit) 3 1, a ROM (Read Only Memory) 32 and a controller 32. DCU 14 is responsible for all of the digital editing processes. Through the use of DCU 14, video segments may be edited and rearranged. Thus, one may use DCU 14 to rearrange the scenes in a movie, alter the movie sound track, etc."). The components of the Digital Control Unit 14 are disclosed to be particular structures. Id. at 6:53-62 ("CPU 31 is a microprocessor of the type described in connection with the CPU 28 of VCU 12. ['The Intel 80286, Intel 80386, Motorola 68020, and Motorola 68030 are examples. A more complete description of the microprocessors can be found in the Oct. 27, 1988 issue of Electronic Design News (EDN), pages 231 and 242, or in the applicable data sheets.'] Controller 33 is a integrated circuit which handles the timing and aids in communication between DCU 14 and memory 13. ROM 32 holds the necessary step-bystep editing programs which are installed at the factory. A currently available example of a suitable ROM for this application is the Texas Instruments part TMS47256. CPU 31 and controller 33 together control the editing process as they execute the programs stored in ROM 32."). The editing function also requires a user interface. The structures linked to this part of the editing function are also disclosed. Id. at 6:40-48 ("A user interface control panel of DCU 14 allows a user to select a desired frame number from a menu on the display. The VCR-ET then EXPERT REPORT OF JOEL HALPERN RE: CLAIM CONSTRUCTION Civ. Case No. 3:06-CV-00019 (MHP) 44 Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 17 of 31 displays a strip of frames (including several frames before and after the selected frame). The user can delete frames in a strip, select a point where other frames are to be inserted into the program, or enhance different frames. A light pen or mouse can be used to select individual frames in a strip."). This combination of structures, which includes (1) Digital control unit 14 which includes (a) CPU (Intel 80286 or 80386 or Motorola 68020 or 68030), (b) ROM (TI TMS472.56) and (c) integrated circuit controller; and (2) user interface control panel, light pen or mouse, is the only set that is clearly linked and is necessary to perform the function of receiving audio/visual source information in the '995 patent. Burst's proposed construction, which focuses on a generic "processor for executing stored editing software pursuant to the stated function" is incorrect because it is incomplete - the patent discloses several structures in addition to a CPU that are clearly linked and necessary to perform the editing function. One of these structures, as I mentioned above, is a ROM (i.e. TI TMS47256). The ROM comes preloaded from the factory with editing programs burned in. Id. at 6:57-60. b. '995 patent, claim 20 The '995 patent discloses the same structures linked and necessary to perform the function in claim 20 of "editing said selectively decompressed time compressed representation . . . and for storing . . . in said random access storage means," as for the function in claim 2. c. '995 patent, claim 21 The '995 patent discloses the same structures linked and necessary to perform the function in claim 21 of "editing said selectively decompressed time compressed representation," as for the function in claim 2.

Opinion A person of ordinary skill in the art in the 1988-1989 timeframe would not recognize "decompression means" as referring to a particular structure. For the '995 patent, the only structure that is clearly linked and is necessary to perform the function of decompressing audiolvideo source information is the AMD 7971 fax compression chip. There is no structure that is clearly linked to the function of decompressing a "time compressed representation" of audiolvideo source information. 2. Bases and Reasons One of ordinary skill in the art would have understood that the phrase "decompression means" did not connote a particular structure. This is true for all of the reasons discussed above for the phrase "compression means." As discussed above, the only structure disclosed in the '995 patent for compression or decompression is the AMD 7971 fax compression chip. However, the AMD 7971 chip could only accomplish data compression and decompression. There is no structure that is linked to the function of decompressing a "time compressed representation."

Opinion One of ordinary skill in the art in the 1998-1999 timeframe would not recognize "recording means, including a removable recording medium" as referring to a particular structure or class of structures. The structures that are clearly linked and are necessary to perform the function of "storing the time compressed representation" are (1) the recording unit that uses removable magnetic tape, removable WORM optical disk, or removable erasable optical disk, and (2) shunt switch. 2. Bases and Reasons One of ordinary skill in the art would have understood that the phrase "recording means" did not connote a particular structure. The term "recording" is generic and functional language. Recording is a function, not a structure. The "means" language would not identify to one of skill in the art which structures, for purposes of the claims, perform the recording and storing function. To determine what structures disclosed in the patents are both clearly linked and are necessary to perform the function performed by the "recording means, including a removable recording medium" of "storing the time compressed representation," I have reviewed each patent individually. a. '995 patent The specification of the '995 patent discloses several structures that are linked to the function of storing by recording. See Exh. B ['995 patent] at 3:38-40 ("The audiolvideo recording unit AVRU 11 may be a video cassette recorder similar to a conventional VCR in which the storage media 23 is a magnetic tape."); id. at 3:58-4:7 ("VCR-ET 10 can achieve both record and play capabilities by using optical discs as media 23. . . . A first type of optical disc may comprise a WORM (Write Once Read Many) optical disc. . . . A second and preferred type of optical disc to be used in AVRU 11 is an erasable optical disc."). EXPERT REPORT OF JOEL HALPERN RE: CLAIM CONSTRUCTION 47 Civ. Case No. 3:06-CV-00019 (MHP) Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 20 of 31 The recording means also requires a shunt switch 48' to couple the video recording unit to the storage means so that the time compressed representation can be stored. The shunt switch is necessary to bypass the time base generator 48 to record compressed signals in an uncorrected time based mode. In the course of converting the decompressed signals from the VCU 12 for use by the AVRU 11 the signals are synchronized by the time base generator (TBG) or corrector 48. TBG 48 can be by passed by a shunt switch 48' for the purpose of transmitting either compressed or decompressed signals from VCU 12 directly to the AVRU 11 in an uncorrected time based mode. See id. at 5:63-6:2. The recording unit that uses removable magnetic tape, removable WORM optical disk, or removable erasable optical disk, and shunt switch, are the only structures clearly linked and necessary to perform the function of analog to digital conversion. Burst's construction is incorrect because it ignores the requirement that the recording means "include[e] a removable recording medium." Burst's construction is also incorrect because it ignores the fact that a shunt switch is part of the structure required for storing the time compressed representation on removable media.

RIGHT TO SUPPLEMENT These opinions are based upon the materials I have reviewed and the constructions proposed by Apple and Burst. I reserve the right to supplement these opinions if new material is brought to my attention or if Apple or Burst seek to support their constructions with materials or arguments I have not considered. I also reserve the right to reply or comment on reports or briefs that I understand Burst may submit in this case. VI. PERSON OF ORDINARY SKILL IN THE ART A. Opinion A person of ordinary skill in the art would have at least a bachelors degree in computer science or electrical engineering and about two years of experience, or equivalent. B. Basis and Reason It is my understanding that in establishing a determination of what represents "ordinary skill in the art" in any particular case, one should take into account the following factors: (1) the educational level of the inventor; (2) the type of problems encountered in the relevant field; (3) prior art solutions to these problems; (4) the speed with which innovations are made in the field; (5) the sophistication of the technology in the field; and (6) the educational level of workers active in the field. My opinion is based upon my personal knowledge of the field of networking and computers in the late 1980s, and upon the nature of the Burst patents, specifically the technology described in the specification and the claims. The level of sophistication of the technology described in the patent is relatively low, particularly in the context of networking and computer technology in the late 1980s. I understand that the named inventor, Mr. Lang, does not have a technical degree and has said that he knows no computer code and that he hardly touched a computer before getting his patents. This is consistent with the conclusion I reached from my knowledge of the field and my review of the patents, including the claims. The level of skill in EXPERT REPORT OF JOEL HALPERN RE: CLAIM CONSTRUCTION 49 Civ. Case No. 3:06-CV-00019 (MHP) Case 3:06-cv-00019-MHP Document 72-3 Filed 12/09/2006 Page 22 of 31 the art for the patents at issue is relatively low: a bachelors degree in computer science or electrical engineering and a few years of experience, or the equivalent. In forming my opinion I also considered the prosecution histories and the various documents cited in my report and listed in Section VIII, Information Considered. VII. COMPENSATION I am being compensated for my work in connection with this litigation at a rate of $425 an hour. My compensation does not depend in any way on the outcome of this case or the resolution of any claim construction issues. VIII. PREVIOUS TESTIMONY In the past 4 years, I have testified at trial or by deposition in the following patent case: StorageTek v. Cisco (on behalf of Cisco) and Toshiba v.
