`Declaration of Dan Marom
`Petition for Inter Partes Review of
`Reissue Patent No. RE42,678
`
`
`I, Dan Marom, declare as follows:
`
`I.
`
`INTRODUCTION AND QUALIFICATIONS
`
`1.
`
`I have been engaged by Ciena Corporation, Coriant Operations, Inc.,
`
`Coriant (USA) Inc., and Fujitsu Network Communications, Inc. (collectively,
`
`“Petitioner”) to opine on certain matters regarding U.S. Patent No. RE42,678,
`
`hereinafter referred to as the ‘678 patent. Specifically, this declaration addresses
`
`the obviousness of the ‘678 patent in light of the prior art.
`
`A. Education
`
`2.
`
`I am an Associate Professor in the Applied Physics Department at
`
`Hebrew University, Israel, heading the Photonic Devices Group. I received the
`
`B.Sc. Degree in Mechanical Engineering and the M.Sc. Degree in Electrical
`
`Engineering, both from Tel-Aviv University, Israel, in 1989 and 1995,
`
`respectively, and was awarded a Ph.D. in Electrical Engineering from the
`
`University of California, San Diego (UCSD), in 2000.
`
`B. Career Synopsis
`
`3. My 20 year research career in optical communications started during
`
`my Master’s degree, where I investigated free-space, polarization rotation based
`
`bypass-exchange (2×2) space switches, which later on led to the founding of a
`
`start-up company (without my involvement). In my doctoral dissertation I

`Exhibit 1028-5
`
`

`

`Declaration of Dan Marom
`Petition for Inter Partes Review of
`Reissue Patent No. RE42,678
`
`
`demonstrated real-time optical signal processing using parametric nonlinearities
`
`applied to spectrally dispersed light, for possible modulation and detection
`
`schemes in serial ultrafast communications (tera-baud rate and beyond). From
`
`2000 until 2005, I was a Member of the Technical Staff at the Advanced
`
`Photonics Research Department of Bell Laboratories, Lucent Technologies,
`
`where I invented MEMS based wavelength-selective switching solutions for
`
`optical networks and headed the research and development effort of these
`
`solutions. Since 2005, I have been with the Applied Physics Department,
`
`Hebrew University, Israel, where I am now an Associate Professor leading a
`
`research group pursuing my research interests in creating photonic devices and
`
`sub-systems for switching and manipulating optical signals, in guided-wave and
`
`free-space optics solutions using light modulating devices, nonlinear optics, and
`
`compound materials.
`
`C. Career Milestones
`
`4.
`
`I am a Senior Member of the IEEE Photonics Society, and a
`
`Member of the Optical Society of America. From 1996 through 2000, I was a
`
`Fannie and John Hertz Foundation Graduate Fellow at UCSD, and was a Peter
`
`Brojde Scholar in 2006-2007. I currently serve as Senior Editor for IEEE
`
`Photonics Technology Letters, handling photonic devices related submissions.

`
`D. Detailed Research Activity
`
`5.
`
`The following paragraphs describe in more detail some of the
`
`research work I have been involved in. Much of this research involves areas of
`
`technology that are directly related to the subject matter of the patent at issue in
`
`this IPR.
`
`Spectral processing of ultrafast waveforms with parametric nonlinearities:
`
`During my Ph.D, studies (1995-2000), I experimentally developed and
`
`theoretically analyzed the operating principles of spatio-temporal wave-mixing
`
`arranging, demonstrating time-to-space, space-to-time, time-reversal, temporal and
`
`spatial correlators, all based on instantaneous nonlinearities. Select publications in
`
`this area include:

`
`wave mixing for space-to-time conversion,” Opt. Lett., Vol. 24, No. 8, pp.

`
`micromirrors
`
`6.
`
`As a Member of the Technical Staff at Bell Labs’ Photonics Lab
`
`(2000-2005), I initiated and led the complete Bell Labs development effort of the
`
`wavelength-selective switch, including acting as an inventor in these efforts. In
`
`addition, the hybrid integration of arrayed waveguide gratings into a free-space
`
`WSS was demonstrated, as well as off-shoot projects in dispersion compensation
`
`and optimal signal restoration after wavelength conversion.

`
`In the academic environment of the Hebrew University (2005-
`
`present, with appointment as Senior Lecturer; currently Associate Professor en
`
`route to Full Professor), I founded the Photonics Devices Group where my
`
`students pursue diverse projects addressing the near-term and anticipated long-
`
`term needs of the optical communications field. Key achievements of my term
`
`are separated according to topic.

`
`Photonic Spectral Processors: A generalization of a WSS to achieve
`
`arbitrary photonic signal manipulations, controlling the amplitude and phase of
`
`the reflected signal spectral components. A key requirement is fine resolution

`control for in-band signal filtering operations. The latest results have shown
`
`arbitrary filtering at 1 GHz resolution for precise and sharp spectral processing.

`
`Time-to-space conversion: After devoting about ten years in this
`
`research track, during which time I focused mostly on WSS activities, I returned
`
`to this research topic and have injected into my activity photonics knowhow
`
`gained in WDM spectral processors, addressing the resolution-efficiency tradeoff
`
`by way of engineering the nonlinear interaction medium. The latest result
`
`demonstrated direct, complex-amplitude temporal waveform recording by
`
`interferogram

`G. Materials Considered
`
`13. The analysis that I provide in this Declaration is based on my
`
`education and experience in the field of photonics, as well as the documents I
`
`have considered, including U.S. Patent No. RE42,678 (the ‘678 patent) [Ex.
`
`1001], which states on its face that it claims priority to an application filed on
`
`Mar. 19, 2001. I have also reviewed the file wrapper for the ‘678 patent.
`
`14. Furthermore, I have reviewed various relevant publications from the
`
`art at the time of the alleged invention of the ‘678 patent, to which this
`
`Declaration relates. These publications include those listed below:

`II. LEGAL PRINCIPLES USED IN THE ANALYSIS
`
`15.
`
`I am not a patent attorney, nor have I independently researched the
`
`law on patent validity. Attorneys for the Petitioner have explained certain legal
`
`principles to me that I have relied upon in forming my opinions set forth in this
`
`report.
`
`A.
`
`Person Having Ordinary Skill in the Art
`
`16.
`
`I understand that my assessment of claims of the ‘678 patent must be
`
`undertaken from the perspective of what would have been known or understood
`
`by a person having ordinary skill in the art, reading the ‘678 patent on its relevant
`
`filing date and in light of the specification and file history of the ‘678 patent. I
`
`will refer to such a person as a "PHOSITA."
`
`17. For the relevant priority date for the ‘678 patent, I have used in my
`
`declaration the earliest application date on the face of the patent: Mar. 19, 2001.
`
`However, I have not yet analyzed whether the ‘678 patent is entitled to that date
`
`for its priority.
`
`18. Counsel has advised me that to determine the appropriate level of
`
`one of ordinary skill in the art, the following four factors may be considered: (a)
`
`the types of problems encountered by those working in the field and prior art
`
`
`
`
`14
`
`Petitioner Ciena Corp. et al.
`Exhibit 1028-18
`
`

`

`Declaration of Dan Marom
`Petition for Inter Partes Review of
`Reissue Patent No. RE42,678
`
`
`solutions thereto; (b) the sophistication of the technology in question, and the
`
`rapidity with which innovations occur in the field; (c) the educational level of
`
`active workers in the field; and (d) the educational level of the inventor.
`
`19. With over 20 years of experience in electrical engineering and in
`
`optical communications, I am well acquainted with the level of ordinary skill
`
`required to implement the subject matter of the ‘678 patent. I have direct
`
`experience with and am capable of rendering an informed opinion on what the
`
`level of ordinary skill in the art was for the relevant field as of March 2001.
`
`20. The relevant technology field for the ‘678 patent is free-space
`
`photonic switching sub-systems, a field related to free-space optics. Based on
`
`this, and the four factors above, it is my opinion that PHOSITA would have been
`
`an engineer or physicist with at least a Master’s degree, or equivalent experience,
`
`in optics, physics, electrical engineering, or a related field, including at least three
`
`years of additional experience designing, constructing, and/or testing optical
`
`systems.
`
`21. My analysis and opinions regarding the ‘678 patent have been based
`
`on the perspective of a person of ordinary skill in the art as of March 2001.
`
`B.
`
`Prior Art
`
`22.
`
`I understand that the law provides categories of information that
`
`
`
`

`Exhibit 1028-19
`
`

`

`Declaration of Dan Marom

`Reissue Patent No. RE42,678
`
`
`constitute prior art that may be used to anticipate or render obvious patent claims.
`
`To be prior art to a particular patent claim under the relevant law, I understand
`
`that a reference must have been made, known used, published, or patented, or be
`
`the subject of a patent application by another, before the priority date of the
`
`patent. I also understand that the PHOSITA is presumed to have knowledge of
`
`the relevant prior art.
`
`C.
`
`Identification of Combinations of Prior Art
`
`23.
`
`I understand that the Petitioner is requesting inter partes review of
`
`claims 1-4, 9, 10, 13, 17, 19-23, 27, 29, 44-46, 53, and 61-65 of the ‘678 patent
`
`under the grounds set forth in Table 1, below. I will sometimes refer to these
`
`combinations as Ground Nos. 1 and 2 in the remainder of my declaration below.
