INTRODUCTION In opining on validity, Rambus’s expert Mr. Murphy reviewed and relied on not only the
2 3
claims and written descriptions of the asserted patents, but also their prosecution histories. The
4
Manufacturers’ motion to preclude Mr. Murphy from testifying regarding matters gleaned from
5
his review of the file histories of the patents-in-suit and their ancestor applications rests on the
6
theory that only a so-called expert in patent law or PTO procedure is qualified to review and
7
opine on the file histories or what the Manufacturers describe as “PTO procedures.” The file
8
histories form part of the public record to which a person of ordinary skill would look in
9
understanding the patented invention. As an expert in electrical engineering, Mr. Murphy
10
therefore is well qualified to review and opine on the contents of the file histories and the events
11
during the prosecution reflected in them, and the Manufacturers’ argument to the contrary is
12
belied by their own technical experts’ reliance on the prosecution histories. The Manufacturers’
13
motion should be denied.
14
II.
TECHNICAL EXPERTS ARE QUALIFIED TO REVIEW FILE HISTORIES
15
The Manufacturers’ motion must fail because its central premise, that only an expert
16
“qualified . . . in patent office procedure,” patent law, or patent prosecution can testify to the
17
content of file histories or implications that may be drawn from them, Br. at 3, is simply incorrect.
18
The Manufacturers offer no support for this position, which is contrary to well-established
19
principles of patent law. The file histories form an integral part of the public record of an issued
20
patent. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996) (file “history
21
contains the complete record of all the proceedings before the Patent and Trademark Office,
22
including any express representations made by the applicant regarding the scope of the claims”).
23
As such, they are part of the background information that the public, and persons of ordinary skill
24
in the art, may consult to understand the teachings of the patent and what it claims. Id.; see also
25
Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed. Cir. 2005) (en banc) (noting that “the
26
prosecution history can often inform the meaning of the claim language by demonstrating how
27
the inventor understood the invention and whether the inventor limited the invention in the course
28
of prosecution, making the claim scope narrower than it would otherwise be”). Indeed, the file 6331659.1

history is so important a part of this inquiry that when determining the meaning the claims would
2
carry to a person of ordinary skill, courts presume such a person of ordinary skill would review
3
the file history to make such a judgment. Computer Docking Station, Corp. v. Dell, Inc., 519
4
F.3d 1366, 1373-74 (Fed. Cir. 2008) (noting that “the person of ordinary skill is deemed to read
5
the claim terms in the context of the entire patent, including the specification and prosecution
6
history”). As an expert in electrical engineering, Mr. Murphy is more than qualified to review
7
and opine upon the file histories of the patents-in-suit, all of which relate to inventions falling
8
within his area of technical expertise.
9
The Manufacturers themselves have recognized that technical experts appropriately can
10
rely and opine on file histories. Like Mr. Murphy, their technical experts have reviewed and
11
relied upon the prosecution histories of the patents in suit. Declaration of Jennifer Polse in

D. The Manufacturers’ present attempt to apply a different rule to Mr. Murphy than that followed
2
by their own experts should be rejected.

III.
4
MR. MURPHY IS QUALIFIED TO OPINE ON THE FACTS AND INFERENCES THAT CAN BE DRAWN FROM THE FILE HISTORIES OF THE PATENTS-INSUIT
5
As noted above, as an expert in electrical engineering, Mr. Murphy is qualified to review
6
and analyze the public record of the patents-in-suit, which concern technology within his field of
7
expertise. Furthermore, his testimony regarding the file histories falls squarely within the scope
8
of his expertise. He does not opine on the minutia of patent prosecution or PTO practice. Rather,
9
the majority of the testimony to which the Manufacturers object consists of Mr. Murphy’s
10
opinions regarding facts that a person of ordinary skill would appreciate based on his or her
11
review of the patents and file histories. These include the filing, issuance, and priority dates of
12
the asserted patents,1 see Expert Report of Robert J. Murphy Regarding Patent Validity,2
13
(hereinafter “Murphy Report”) ¶¶ 90-99, the identity of prior art disclosed to the patent office
14
during prosecution, id. ¶¶ 103-104, 106, 109-111, 114-116, 118-122, 126-130, 132, 134-136, 138-
15
139, 141-148, and 150-151, examples of office actions in which the examiner required the
16
applicants to identify support in the written description for particular limitations, id. ¶¶ 209-219, a
17
statement in an office action demonstrating an understanding of a claimed “bus” that does not
18
require multiplexing, id. ¶¶ 227-228, and information gleaned from Mr. Murphy’s search and
19
review of the numerous patents Rambus has sought and obtained that claim priority to the ’898
20
application as well as basic background information concerning the filing and prosecution history
21
of the original ’898 application, id. ¶ 41.3

The Manufacturers object to Mr. Murphy’s statement that each patent issued “after a period of evaluation.” Br. at 4. The Manufacturers do not explain why recognizing that the patent office evaluated the patents prior to issuance requires any expertise in patent law or procedure. That the PTO evaluated the patents prior to issuance is readily apparent to any person of ordinary skill upon review of the file histories, which contain correspondence to and from the PTO reflecting an evaluation of the patents.

A copy of the Murphy Report was attached as Exhibit 1 to the Omnibus Declaration of Sven Raz in Support of the Manufacturers’ Summary Judgment And Daubert Motions, filed by the Manufacturers on October 24, 2008. 3 The Manufacturers also seek to preclude Mr. Murphy from testifying regarding paragraph 281 of his report, notwithstanding the fact that that paragraph primarily sets forth Mr. Murphy’s technical opinion regarding support in the written description for the DLL. Br. at 7. Such 6331659.1

The Manufacturers’ objection to Mr. Murphy’s discussion of whether particular references
2
were cited to the examiner is particularly inappropriate in light of their own expert’s explicit
3
statement that, in rendering his opinions on invalidity, he considered the file histories “inclusive
4
of cited references.” Polse Decl., Exh. D. Furthermore, the references cited to the examiner form
5
part of the public record that a person of ordinary skill uses to understand the patented invention.
6
Phillips, 415 F.3d at 1317 (“The prosecution history, which we have designated as part of the
7
‘intrinsic evidence,’ consists of the complete record of the proceedings before the PTO and
8
includes the prior art cited during the examination of the patent.”); Vitronics, 90 F.3d at 1583
9
(holding that “within an analysis of the file history may be an examination of the prior art cited
10
therein”), citing Autogiro Co. of Am. v. United States, 384 F.2d 391, 399 (1967) (“In its broader
11
use as source material, the prior art cited in the file wrapper gives clues as to what the claims do
12
not cover.”). The identity and disclosure of such references therefore is an appropriate subject for
13
testimony for a technical expert.
14
Nor is it true, as the Manufacturers claim, Br. at 5, that Mr. Murphy adds no technical
15
analysis in the portions of his report that they seek to exclude. To the contrary, the paragraphs
16
describing the testimony the Manufacturers seek to exclude, together with the referenced
17
attachments4 and exhibits, set forth Mr. Murphy’s technical opinions regarding various invalidity
18
theories raised in Mr. McAlexander’s report. See, e.g., Murphy Report ¶ 110 (“[a]s I explain in
19
my Attachment A (in response to McAlexander Attachment A), I disagree that SCI in
20
combination with any other reference identified by Mr. McAlexander, renders obvious claim 33
21
of the ’120, claim 3 or 4 of the ’446, or claim 34 of the ’037 patent,” and noting that “[r]egardless
22
of whether SCI was considered by the patent office, it is my opinion that this reference does not
23
render obvious” the claims); id. ¶ 281 (explaining where support exists in the specification for the
24 25 26 27 28
testimony from a technical expert is entirely proper. To the extent the Manufacturers seek only to preclude Mr. Murphy from implying “that the PTO has rendered an additional opinion on the patents’ validity” by stating that he “agrees with the PTO” that the written description is met, Br. at 7 n. 4, Rambus does not intend to elicit that statement from Mr. Murphy. 4
Attachments A-G to Mr. Murphy’s report, which set forth in detail his analysis of the various prior art references cited by Mr. McAlexander, are attached to the Confidential Polse Declaration as Exhibit 2. 6331659.1

DLL limitation); id. ¶ 227 (explaining the technical differences between two groups of claims).
2
Viewed in context, Mr. Murphy’s discussion of the file histories simply form one part of his
3
overall analysis of the prior art and other invalidity issues raised in Mr. McAlexander’s report.
4
In short, Mr. Murphy’s testimony reflected in paragraphs 41, 90-99, 103-104, 106, 109-
5
111, 114-116, 118-122, 126-130, 132, 134-136, 138-139, 141-148, 150-151, 209-219, 227-228
6
and 281 is appropriate based on his technical expertise and his review of the file histories, the
7
patents-in-suit, and the other materials on which he relied. The Manufacturers’ motion to exclude
8
his testimony on the prosecution-history related matters described in those paragraphs of his
9
report should be denied. 5

IV.
11 12
MR. MURPHY’S TESTIMONY REGARDING LEGAL STANDARDS RESPONDS TO MR. MCALEXANDER’S TESTIMONY ON LEGAL STANDARDS The remainder of the testimony that the Manufacturers seek to exclude concerns Mr.
13
Murphy’s understanding of the legal principles bearing on the areas on which he opines. See
14
Murphy Report ¶¶ 88-89, 101-102, & 203-208. These and other explanations of the applicable
15
law contained in Mr. Murphy’s report resemble those contained in the expert report to which Mr.
16
Murphy’s validity report responds. See Corrected Expert Report of Joseph McAlexander
17
Regarding Invalidity, ¶¶ 23-43.6 Rambus agrees that expert witnesses should not testify at trial
18
regarding their understanding of the law, and seeks in its Daubert Motion No. 1, filed on October
19
24, 2008, to preclude Mr. McAlexander from testifying regarding the various legal opinions set
20
forth in his report. See also Rambus’s Daubert and Motion in Limine No. 2 to Exclude Certain
21
Testimony of Peter Heuser, Case No. 05-cv-00334, Docket No. 2432. Should the Court deny
22
Rambus’s Daubert Motion No. 1 and permit Mr. McAlexander to testify regarding his legal
23 5
24 25 26 27 28
It is unclear whether, by this motion, the Manufacturers seek to exclude Mr. Murphy from testifying as to all of the material contained in the paragraphs they deem objectionable as referencing the prosecution or file histories. Br. at 8. Even if exclusion of testimony relating to the prosecution history were appropriate, which it is not, the Manufacturers provide no ground for excluding Mr. Murphy’s testimony on the other matters raised in the objected-to paragraphs of his report. 6
A copy of the pertinent portions of Mr. McAlexander’s report is attached as Exhibit A to the Declaration of Peter Detre filed on October 24, 2008 in support of Rambus’s Daubert Motion No. 1. 6331659.1
