`
`INTRODUCTION
`
`Pursuant to N.D. Cal. Patent L.R. (“Patent Rule”) 3-3 and the Court’s Scheduling Order
`
`(Dkt. 37), Defendant RayVio, Inc. (“RayVio”) serves these Invalidity Contentions on Plaintiff
`
`Nitride Semiconductors, Inc. (“Nitride”). These Invalidity Contentions are based on Defendant's
`
`current knowledge of U.S. Patent No. 6,861,270 (“the ’270 Patent”), Defendants current
`
`understanding and interpretation of the scope of the patent claims as set forth in Nitride’s
`
`Infringement Contentions, and Defendant’s current understanding of the prior art.
`
`RayVio reserves the right to supplement these Invalidity Contentions to the extent
`
`permitted under the Local Rules. RayVio investigation is ongoing. This case is currently in the
`
`10
`
`early stages of discovery. As discovery proceeds, RayVio may learn of additional prior art and
`
`11
`
`information regarding the validity of the Asserted Claims of the ’270 patent. Moreover, Nitride
`
`12
`
`has not yet provided its proposed constructions pursuant to Patent L.R. 4-1 and 4-2. Additional
`
`13
`
`prior art may become relevant based on Nitride’s proposed constructions for the Asserted Claims.
`
`14
`
`Nitride’s constructions may also change the scope of the Asserted Claims thereby altering the
`
`15
`
`bases of invalidity of the Asserted Claims under 35 U.S.C. §§101, 102, 103, and 112.
`
`16
`
`While RayVio has considered Nitride’s Infringement Contentions, the contentions are
`
`17
`
`vague, ambiguous, and fail to specifically identify where each limitation of each asserted claim is
`
`18
`
`found in the accused products. Further, RayVio is not aware of whether Nitride will contend that
`
`19
`
`any limitations of the Asserted Claims are not disclosed by the prior art disclosed herein and, if
`
`20
`
`so, which specific limitations Nitride may allege are not disclosed in each particular prior art
`
`21
`
`reference disclosed herein. It is also unclear whether Nitride will allege that any of the disclosed
`
`22
`
`prior art references do not qualify as prior art. RayVio reserves the right to supplement these
`
`23
`
`Invalidity Contentions to the extent permitted under the Local Rules to address these and other
`
`24
`
`issues and information that may arise during discovery.
`
`25
`
`II.
`
`THE ASSERTED CLAIMS OF THE PATENTS-IN-SUIT
`
`26
`
`In Plaintiff’s Infringement Contentions, Nitride alleges that RayVio infringes claims 1, 2,
`
`27
`
`5, 8, 9, and 12 (collectively “Asserted Claims”).

`
`III. THE ASSERTED CLAIMS OF THE ’270 PATENT ARE EACH INVALID FOR
`ANTICIPATION UNDER 35 U.S.C. § 102 AND/OR OBVIOUSNESS UNDER 35
`U.S.C. § 103 IN VIEW OF THE PRIOR ART [PATENT RULES 3-3(A), (B) AND
`(C)]
`
`Pursuant to Patent Rules 3-3(a), (b) and (c), RayVio contends that each of the Asserted
`
`Claims is invalid as anticipated by the prior art under 35 U.S.C. § 102 and/or as obvious in view
`
`of the prior art under 35 U.S.C. § 103. The identification of any patent or patent publication
`
`herein shall be deemed to include any counterpart patent or application filed, published, or issued
`
`anywhere in the world.
`
`RayVio’s claim charts in Exhibits 1-27 cite particular teachings and disclosures in the
`
`prior art that identify where each limitation is found in the reference. One of ordinary skill in the
`
`art would read the reference as a whole and in the context of the knowledge, literature, and
`
`publications in the field. RayVio cites exemplary portions of the prior art references in Exhibits
`
`1-27. RayVio reserves the right to rely on uncited portions of the prior art references in these
`
`exhibits, as well as other publications and expert testimony, to inter alia provide context and
`
`assist in understanding the cited portions and as evidence that a claim limitation is known or
`
`disclosed. Further, any citation to a figure in the exhibits is inclusive of all discussions of that
`
`figure in the reference. To establish bases for combinations of certain cited references that render
`
`the Asserted Claims obvious, RayVio reserves the right to rely on the general knowledge of one
`
`or ordinary skill in the art and common sense as well as uncited portions of the prior art
`
`references, other publications, and documents incorporated by reference.
`
`Because the parties have not yet exchanged proposed constructions and the Court has not
`
`yet construed the claims, there is uncertainty regarding the scope of the Asserted Claims. The
`
`prior art in Exhibits 1-27 may contain alternative interpretations of the prior art to account for the
`
`uncertainty as to the scope of the Asserted Claims, which have not been construed by the Court.
`
`Nothing stated herein shall be treated as an admission or suggestion that RayVio agrees with
`
`Nitride regarding either the scope of the Asserted Claims or the construction of a claim term.
`
`Nothing stated herein shall be construed as an admission or a waiver of any particular
`
`construction of any claim term. RayVio expressly reserves the right to contest any claim

`

`

`
`construction asserted by Nitride.
`
`The background and state of the art at the time of the purported invention of the ’270
`
`patent is exemplified by at least the references found at RV00000143 - RV00005917. Each of
`
`these references show the state of the art regarding gallium nitride based semiconductors and light
`
`emitting elements at the time the ’270 patent was filed. These references discuss the making,
`
`structure, and use of gallium nitride based semiconductors and light emitting devices. RayVio
`
`reserves the right to rely on additional references produced in discovery to provide a background
`
`of the technology, to provide context to the invention and the prior art, to show the knowledge of
`
`one of ordinary skill in the art, and for other background purposes.
`
`A.
`
`Priority Date of the ’270 Patent
`
`In Nitride’s Infringement Contentions pursuant to Patent L.R. 3-1, Nitride identifies the
`
`12
`
`filing date of the ’270 patent, March 6, 2002, as the asserted priority date. No other priority date
`
`13
`
`is stated in Nitride’s Infringement Contentions. Other than March 6, 2002, Nitride does not assert
`
`14
`
`any specific conception or reduction to practice dates in its Infringement Contentions pursuant to
`
`15
`
`Patent L.R. 3-1. Nitride has also not identified any documents relating to conception, reduction to
`
`16
`
`practice, design, and development of the claimed inventions of the ’270 patent as required by
`
`17
`
`Patent Local Rule 3-2. Therefore, RayVio’s Invalidity Contentions are based on Nitride’s current
`
`18
`
`asserted priority date of March 6, 2002. If Nitride amends its infringement contentions to assert
`
`19
`
`an earlier priority date, RayVio reserves its right to amend its invalidity contentions to address
`
`20
`
`Nitride’s amendments.
`

`

`
`B.
`
`Anticipation
`
`Claims 1, 2, 5, 8, 9, and 12 of the ’270 patent are each anticipated by the prior art
`
`23
`
`references shown in the table below. The table identifies the claims anticipated by each reference
`
`24
`
`and the Exhibit containing the claim chart that identifies where each limitation of the Asserted
`
`25
`
`26
`
`27
`
`28
`
`Claims is found in that reference.1
`
`
`1 The claim charts provide illustrative citations to where each element may be found in the prior
`art references. The cited references may contain other disclosures of each claim element as well,
`and RayVio reserves the right to argue any claim elements of the ’270 patent are disclosed in non-
`cited portions of these references.

`
`Obviousness
`
`“The combination of familiar elements according to known methods is likely to be
`
`obvious when it does no more than yield predictable results.” KSR Int’l Co. v. Teleflex Inc., 550
`
`U.S. 398, 416 (2007). “When a work is available in one field of endeavor, design incentives and
`
`other market forces can prompt variations of it, either in the same field or a different one.” Id. at
`
`417. “For the same reason, if a technique has been used to improve one device, and a person of
`
`ordinary skill in the art would recognize that it would improve similar devices in the same way,
`
`using the technique is obvious unless its actual application is beyond his or her skill.” Id.
`
`In determining whether one of ordinary skill in the art would have been motivated to
`
`combine multiple references, one can “look to interrelated teachings of multiple patents; the
`
`effects of demands known to the design community or present in the marketplace; and the
`
`background knowledge possessed by a person having ordinary skill in the art.” Id. at 418.

`
`“[A]ny need or problem known in the field of endeavor at the time of invention and addressed by
`
`the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420.
`
`The motivation to combine the teachings of the prior art references disclosed herein is
`
`found in the references themselves and/or: (1) the nature of the problem being solved; (2) the
`
`express, implied, and inherent teachings of the prior art; (3) the knowledge of persons of ordinary
`
`skill in the art; (4) the fact that the prior art is generally directed towards the same or similar
`
`problems; and/or (5) the predictable results obtained in combining the different elements of the
`
`prior art.
`
`1.
`
`Obviousness Based on Knowledge of One of Ordinary Skill in the Art
`
`10
`
`It is RayVio’s contention that each of the references listed above in Section III.B.
`
`11
`
`anticipates the Asserted Claims of the ’270 patent. If any limitation of any Asserted Claim is
`
`12
`
`found missing from any anticipatory reference identified above in Section III.B., then that
`
`13
`
`limitation and that claim would have been obvious based on the disclosure of the reference and
`
`14
`
`the knowledge of one of ordinary skill in the art. ’
`
`15
`
`16
`
`17
`
`2.
`
`Obviousness Combinations
`
`a.
`
`Obviousness combinations including JP10079501
`
`JP10079501 in combination with any one of the following references renders the Asserted
`
`18
`
`Claims invalid as obvious: JP11354843; ’798 Patent; ’241 Patent; ’535 Patent; ’232 Patent; ’757
`
`19
`
`Patent; JP2000174337; JPA_2000349333; Kawasaki Reference; Sumiya Reference; Tanaka

`
`22
`
`Reference 1; Smith Reference 2; Bottcher Reference, Chaly Reference. One of ordinary skill in
`
`23
`
`the art would have been motivated to combine the teachings of JP10079501 with each of the
`
`24
`
`references identified above to create the following combinations, which would render the
`
`25
`
`Asserted Claims of the ’270 patent invalid for obviousness.

`
`12
`
`The similarities in the structure, function, and purpose of the disclosed invention (e.g.,
`
`13
`
`creating a light emitting element that includes a substrate, gallium nitride based layers, and a
`
`14
`
`“composition material” or “lattice mismatch layer”) would motivate a skilled artisan to combine
`
`15
`
`the teachings of the JP10079501 with any of these other aforementioned references. These
`
`16
`
`similarities also ensure that such a combination produces predictable results by simply adding or
`
`17
`
`substituting known features from one reference describing light emitting semiconductor elements
`
`18
`
`containing gallium nitride based semiconductor materials in the JP10079501 reference, which
`
`19
`
`similarly describes light emitting semiconductor elements containing gallium nitride based
`
`20
`
`semiconductor materials. One of ordinary skill in the art would have recognized that the
`
`21
`
`techniques used in the aforementioned references would have similar benefits in the context of
`
`22
`
`the teachings of JP10079501. Further, design and market concerns would have motivated one of
`
`23
`
`ordinary skill in the art to combine the JP10079501 with the references identified above.
`
`24
`
`It would have been a routine exercise for one of ordinary skill in the art to combine the
`
`25
`
`teachings of JP10079501 with the identified references to arrive at the claimed invention, as the
`
`26
`
`overlapping nature of their respective teachings confirms that such combinations had already
`
`27
`
`been achieved in the prior art and would not introduce any additional complexity or
`
`28
`
`unpredictability. As evidenced by the prior art cited herein, gallium nitride based semiconductors

`
`with light emitting elements, including “composition materials” and “lattice mismatch layers,”
`
`were commonplace as of the priority date of the ’270 patent. A person of ordinary skill in the art
`
`seeking to solve the problem identified by the patentee would have looked to analogous art for
`
`such a solution. As noted above, the solution identified by the patentee had already been
`
`identified by others in the field. One of ordinary skill in the art, thus, would have been motivated
`
`to combine such analogous teachings in the same manner proposed by the patentee.
`
`JP10079501 and the identified references would be motivated to combine these references
`
`because they address the same goal (e.g., to improve light emission from a gallium nitride based
`
`semiconductor device). Within this known work in this field of endeavor, a person of ordinary
`
`10
`
