ORDER GRANTING DEFENDANTS MOTION FOR SUMMARY JUDGMENT FOR BEST MODE VIOLATION

Defendant Applied Materials, Inc.’s (“Applied”) motion for summary judgment on best mode violation was heard on February 9, 1996. The court has read the moving and responding papers and heard the argument of counsel. For the reasons set forth below, the court grants defendant’s motion.

I. BACKGROUND

On October 17, 1989, plaintiff Advanced Semiconductor Materials America, Inc. (“ASM”) was issued U.S. Patent No. 4,874, -464 (“the ’464 patent”), which describes a “process for epitaxial deposition of silicon.” On January 11, 1993, ASM filed suit against Applied alleging that Applied’s “Centura Epitaxial reactor” infringes its patent in violation of 35 U.S.C. sections 271 and 281.

On October 14, 1994, Applied filed a motion for partial summary judgment, arguing that ASM’s patent is invalid for failure to comply with the “best mode” requirement. Applied contended that the patent allegedly disclosed an ineffective method of heating, radio frequency (“RF”) heating (also called inductive heating), and did not disclose the “best mode” of practicing the patent, radiant (“IR”) heating (also called lamp heating). On November 7, 1994, ASM filed an opposition and countermotion for summary judgment on the best mode defense, in which it contended that it was entitled to summary judgment on the best mode defense because it disclosed IR heating through incorporation by reference to another patent, U.S. Patent No. 4,828,224 (the “Crabb patent”), and because the heating system is not part of the claimed invention and thus no disclosure was necessary. Further, ASM contended that Applied should not be granted summary judgment because factual issues remain as to whether the inventors of the ’464 patent contemplated IR heating as the best mode and whether one of ordinary skill in the art would know from the ’464 disclosure that the claimed process could be performed effectively with IR heating. On December 16, 1994, this court denied both ASM’s and Applied’s motions for summary judgment on the best mode defense. In denying Applied’s motion the court stated “a reasonable juror, in considering the inventors’ declarations, could find that the defendant has not shown “with convincing clarity’ that the inventors contemplated that only IR heating would be effective.”

On November 3, 1995, defendant Applied filed another motion for summary judgment on the best mode violation based on discovery taken after this court’s December 16, 1994 order. Applied alleges that admissions made during such subsequent discovery by the inventors “establishes that the only plausible conclusion is that lamp heating was preferred by the inventors because, among other things, it provides uniform heating.” ASM opposes the motion contending Ap plied’s present motion is procedurally flawed since Applied failed to first seek court leave for reconsideration of the court’s prior ruling on the best mode issue. ASM also reargues that it properly disclosed the IR heating through its incorporation of the Crabb patent application by reference and that the ’464 patent adequately discloses to a person of ordinary skill that the ’464 process could be used on a radiantly heated reactor.

II. LEGAL STANDARDS

Summary judgment is proper when “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Fed.R.Civ.P. Rule 56(c). There is a “genuine” issue of material fact only when there is sufficient evidence such that a reasonable juror could find for the party opposing the motion. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 251-52, 106 S.Ct. 2505, 2511-12 , 91 L.Ed.2d 202 (1986). Entry of summary judgment is mandated against a party if, after adequate time for discovery and upon motion, the party fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial. Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 2552 , 91 L.Ed.2d 265 (1986). This court, however, must draw all justifiable inferences in favor of the nonmoving parties, including questions of credibility and of the weight to be accorded particular evidence. Masson v. New Yorker Magazine, Inc., 501 U.S. 496, 520 , 111 S.Ct. 2419, 2435 , 115 L.Ed.2d 447 (1991).

III. ANALYSIS

A. Procedural issue

As a threshold matter, ASM argues that Applied’s motion for summary judgment on a best mode violation is improperly brought in violation of the local rules because Applied did not seek leave to file a motion for reconsideration pursuant to Civil Local Rule 7-9. Moreover, ASM contends that even if Applied’s motion is treated as a motion for leave, the motion does not satisfy the procedural requirements of Civil Local Rule 7-10. Finally, ASM argues that even if the procedural rules are waived, Applied has failed to prove any of the allowable bases for a motion for reconsideration.

Applied has not filed a motion for reconsideration. Def. Reply Supp.Summ.J. Best Mode at 3, fn. 1. It filed a renewed motion. A moving party may renew a motion for summary judgment notwithstanding denial of an earlier motion by showing a different set of facts or some other reason justifying renewal of the motion. William W. Schwarzer et al., Federal Civil Procedure Before Trial ¶ 14:367 (1995). The earlier denial is not res judicata or “law of the case.” Id. (citing Preaseau v. Prudential Ins. Co. of America, 591 F.2d 74, 79 (9th Cir.1979); Golden Gate Hotel Ass’n v. City & County of San Francisco, 18 F.3d 1482, 1485 (9th Cir.1994)). Applied argues that its current motion for summary judgment is based on new evidence obtained in recent depositions including those of the inventors. After reviewing the moving and responding papers, this court finds that there is a basis for Applied’s renewed motion.

B. Substantive issue

35 U.S.C. section 112 states that the specification in the patent application “shall set forth the best mode contemplated by the inventor of carrying out his invention.” The essence of the “best mode” requirement is to compel an inventor to disclose the best mode contemplated by him, as of the time he files the patent application, of carrying out his invention. Chemcast Corp. v. Arco Industries Corp., 913 F.2d 923, 926 (Fed.Cir.1990) (“Chemcast ”). The sole purpose of such requirement is to restrain inventors from applying for patents while at the same time concealing from the public preferred embodiments of their inventions which they have in fact conceived. Id. It is immaterial whether that failure to disclose is intentional or accidental. Dana Corp. v. IPC Ltd. Partnership, 860 F.2d 415, 418 (Fed.Cir.1988), ce rt. denied, 490 U.S. 1067 , 109 S.Ct. 2068 , 104 L.Ed.2d 633 (1989) (“Dana”). See also Envirex Inc. v. EMC Corp., 28 U.S.P.Q.2d 1752 , 1756, 1993 WL 572321 (E.D.Wis.1993), aff'd, 16 F.3d 420 (Fed.Cir.1993) (unpublished) (no requirement that failure to disclose be intentional before it can violate the best mode requirement). Compliance with the best mode requirement is generally a question of fact. Shearing v. Iolab, 975 F.2d 1541 (Fed.Cir.1992). However, best mode may be determined as a matter of law if reasonable minds could not differ on whether the best mode requirement is satisfied. Dana, 860 F.2d at 419-420 .

A defendant relying on the “best mode” defense must prove two elements: (1) that the “inventor knew of a mode of practicing the claimed invention that he considered to be better than any other at the time he filed his application” and (2) that the inventors failed to adequately disclose this preferred embodiment of the invention. Transco Products Inc. v. Performance Contracting, Inc., 38 F.3d 551, 560 (Fed.Cir.1994) (“Transco Products”) (citing Chem-cast, 913 F.2d at 927-928 ). The first element concerns a subjective factual question: what the inventors believed at the time they filed the application. Envirex Inc. v. FMC Corp., 28 U.S.P.Q.2d at 1757-58. The second element concerns an objective question: whether the disclosure is adequate to enable one skilled in the art to practice the best mode. Id. “Of necessity, the disclosure required by section 112 is directed to those skilled in the art.” Chemcast, 913 F.2d at 926 . The adequacy of a best mode disclosure is therefore a function not only of what the inventor knew but also of how one skilled in the art would have understood his disclosure. Id. at 927 . “However, merely because a technique is generally known in the art ... does not eliminate a best mode defect.” Wahl Instruments, Inc. v. Acvious, Inc., 950 F.2d 1575, 1580 (Fed.Cir.1991) (“Wahl ”) (emphasis in original). There is a best mode violation where an inventor contemplated an undisclosed method which was necessary to his invention and affected how well it worked. Id. Moreover, there may be a best mode violation even where there is a general reference to the best mode of practicing the claimed invention if the quality of the disclosure is so poor as to effectively conceal it. Transco Products, 38 F.3d at 560 .

1. Contemplation of the Best Mode

ASM argues that nothing has changed since Applied’s last summary judgment motion on this issue in which the Applied failed to prove that the inventors contemplated any heating source as part of the ’464 process best mode. The court disagrees.

The ’464 patent lists five inventors, Dennis L. Goodwin (“Goodwin”), Mark R. Hawkins (“Hawkins”), Wayne L. Johnson (“Johnson”), Aage Olsen (“Olsen”), and McDonald Robinson (“Robinson”). At the time of the prior motion for summary judgment, Applied offered various portions of the then existing deposition transcripts of the inventors to support its best mode defense. Inventor Hawkins testified that he never actually worked with an RF-heating apparatus while at ASM. He furthered testified that the reference to RF-heating in the ’464 patent was an error; “[t]hey meant IR instead of RF.” Reines Decl. (1994) Ex. D at 160. He also affirmed that lamp heating is the method that ASM decided was the best way to achieve temperature uniformity in the ’464 patent. Id. Inventor Goodwin further supported that ASM was not using RF heating. Reines Deel. (1994) Ex. E at 58. Goodwin stated that the references to RF-heating in the ’464 patent were a “screw[] up,” a “typo,” and a “mistake” because RF heating “ha[d] nothing to do with this patent other than prior art.” Id. Inventor Olsen stated that he understood that ASM had tried RF heating as well as IR heating before he had arrived and had finally settled on radiant heating. Reines Deck (1994) Ex. F at 132.

ASM, in opposition, offered the declarations of four of the five inventors of the ’464 patent, all of whom were ASM employees, to support its contention that the inventors never contemplated IR heating as the best mode. Each declaration contained precisely the same, language regarding the inventor’s contemplation of IR heating as the best mode:

Goodwin Decl. (1994) ¶ 5; Hawkins Decl. (1994) ¶ 6; Olsen Decl. (1994) ¶ 6; Robinson Decl. (1994) ¶ 6.

Applied argued that these declarations conflicted with earlier deposition testimony and should not be considered. However, the court noted that it did not need to decide whether it found the inventors’ declarations persuasive; rather, it only needed to decide whether a reasonable jury could find the best mode defense lacking. The court concluded that a reasonable juror could so find and therefore denied summary judgment as to Applied’s best mode defense.

In the present motion, ASM argues that the inventors have not recanted their previously submitted declarations and therefore there still exists a question of fact regarding whether the inventors contemplated radiant heating as the best mode. Although the inventors have not recanted their declarations, Applied’s subsequent depositions of inventor Hawkins on October 18, 1995, inventors Goodwin and Robinson on October 19, 1995 and inventor Olsen on October 20, 1995 shed new light on what the inventors understood their declarations to mean and what they contemplated about radiant heating and the ’464 process.

Inventor Robinson was the Epsilon group’s Director of Analysis and Research, and the number two technical person behind inventor Johnson. During his deposition, Robinson clarified his understanding of the last sentence in the above mentioned excerpt from the inventors’ uniform declarations:

Reines Decl. (11-3-95) Ex. B [Robinson Depo.] at 437:5-437:20.

Robinson also acknowledged that lamp heating was preferred over RF-heating particularly because RF-heating had problems obtaining temperature uniformity in the 4r-6 inch wafers which were standard in the late-1980’s.

Reines Decl. (11-3-95) Ex. B [Robinson Depo.] at 428:21-429:2.

Reines Decl. (11-3-95) Ex. B [Robinson Depo.] at 444:11-445:11, 446:11-18.

Moreover, on September 10, 1984, Robinson participated in a presentation which announced to the corporate technical advisory board that one of the important conclusions reached to date was that “[l]amp arrays presently offer the best means for heating single wafers.” Reines Decl. (11-3-95) Ex. C.

Not only did Robinson acknowledge that radiant heating was the best mode for the ’464 process, he also testified that ASM was committed to the use of radiant heating and did not give further serious consideration to RF heating by the time it was working on the hot pickup. Reines Deck (11-3-95) Ex. B [Robinson Depo.] at 445:23-146:5. Moreover, he testified that he participated in the decision not to pursue RF-heating. Reines Deck (11-3-95) Ex. B [Robinson Depo.] at 436:14-17. Robinson, therefore, clearly believed by the time of filing the patent application that radiant heating was the best mode.

Inventor Johnson was the head of the technical team. He testified that by September 1984, he had concluded that lamp arrays offered the best means for heating a single wafer. Reines Deck (11-3-95) Ex. D [Johnson Depo.] at 105:6-13. He also acknowledged that he agreed with the technical decision to use radiant heat in the project. Reines Deck (11-3-95) Ex. D [Johnson Depo.] at 79:13-21. Therefore, Johnson also believed at the time of filing the patent application that radiant heating was the best mode.

Inventor Olsen testified he never actively thought about using RF-heating for the process. He just concentrated on developing the lamp-heated Epsilon reactor on which he was working.

Reines Deck (11-3-95) Ex. E [Olsen Depo.] at 215:10-21.

Olsen also testified that he did not know if other types of heating could achieve the same type of uniformity as radiant heating.

Reines Deck (11-3-95) Ex. E [Olsen Depo.] at 220:16-23. Therefore, at the time of the patent application the best heating mode of which Olsen was aware, indeed the only heating method which Olsen knew worked in performing the process, was radiant heating.

Inventor Hawkins also admitted that by 1988, he was only considering lamp-heating for the ’464 process.

Reines Decl. (11-3-95) Ex. F [Hawkins Depo.] at 448:10-19. Hawkins, therefore, while implicitly acknowledging that other heating systems had been considered, admitted that radiant heating was the only method considered for the ’464 process by the time of filing the patent application.

Finally, inventor Goodwin, testified that he had only used lamp heating and consequently did not know how effective other heating systems would be or what would be required to make them effective.

Reines Decl. (11-3-95) Ex. G [Goodwin Depo.] at 180:9-23. Like Olsen, at the time of the patent application the best heating mode of which Goodwin was aware, indeed the only heating method which Goodwin knew worked in performing the process, was radiant heating.

Armand Ferro, the Epsilon project’s general manager, and a participant in the application process for the ’464 patent, also testified regarding the choice between IR and RF heating. He explained that RF heating was not used because it was “very difficult” and “impractical” to get the required uniformity.

Reines Decl. (11-3-95) Ex. H [Ferro Depo.] at 170:25-171:16; 172:3-7.

Moreover, Ferro testified that lamp heating was selected for ASM’s commercial embodiment of the ’464 process because “it was the most convenient and readily available commercially, and it was very efficient from a power viewpoint.” Reines Decl. (11-3-95) Ex. I [Ferro Depo.] at 168:19-25.

For the above reasons, the court finds that no reasonable jury could find other than the fact that the inventors contemplated IR (lamp/radiant) heating as the best mode for practicing the invention. It was, in fact, the only mode with which the inventors, at the time for filing the patent application, were able to obtain the temperature uniformity essential to the process.

2. Adequate Disclosure

Having found that the inventors contemplated IR heating as the best mode for practicing the ’464 patent, the court now examines whether it was adequately disclosed in the patent.

Relying on Chemcast, ASM argues that the ’464 patent adequately discloses to a person of ordinary skill in the art that the ’464 process could be used on a radiantly heated reactor. Applied contends that ASM misreads Chemcast. Applied argues that the Chemcast court allowed the level of skill in the art to overcome a best mode violation only where the best mode was so basic that one of ordinary skill in the art would inherently know what the inventor contemplated as his or her best mode. The court agrees with Applied. Although the best mode inquiry is to be answered in the context of those skilled in the art, a best mode defect is not eliminated merely because a technique is generally known in the art. Wahl Instruments, Inc. v. Acvious, Inc., 950 F.2d 1575, 1580 (Fed.Cir.1991) (“Wahl”).

In this case, two of the inventors admitted that the reference to RF heating rather than radiant heating in the specification was an error. Inventor Goodwin testified that RF heating “ha[d] nothing to do with this patent other than prior art.” Indeed, the inventors here knew that the undisclosed radiant heating worked better than RF heating as described in the specification. RF heating had been abandoned by the inventors because it “would have required a significant engineering effort,” it was “very difficult” and it was “impractical” to obtain temperature uniformity essential to the ’464 process. In light of what the inventors knew, the specification, as issued, was manifestly deficient. Moreover, in light of the level of skill in the art, radiant heat was not implicitly disclosed. ASM’s own expert opined that those of “ordinary skill in the art knew that there were at least three types of heating mechanisms [including RF heating and radiant heating] that could be used to heat wafers effectively in a CVD reactor.” Gilmore Decl. Ex. 1054 at ¶¶17, 18, 20. Therefore, given the specification, one skilled in the art simply could not divine the inventors’ preferred heating mode. Chemcast, 913 F.2d at 929 .

ASM next contends that the ’464 patent adequately disclosed the best mode through its incorporation by reference to the Crabb patent application. Applied, on the other hand, argues that the Crabb patent application is not properly incorporated by reference because ASM did not follow the guidelines for incorporation set forth in the Patent and Trademark Offices’ Manual of Patent Examining Procedure (“MPEP”), which provides:

MPEP § 608.01(p)(B) (5th ed. rev.1987) (emphasis added) (citations omitted). Furthermore, the MPEP provides:

MPEP § 608.01(p)(B) (5th ed. rev. 1988) (emphasis in original).

Applied argues that ASM treated the Crabb patent application as containing nonessential matter during patent prosecution. Moreover, ASM argued during the prior motion for summary judgment for best mode violation that the heating system was not part of the claimed invention and therefore no disclosure of it is necessary. The court disagreed and concluded that the heating method was essential matter. The Examiner’s failure to require ASM to amend its application for essential material incorporated by reference, in accordance with the MPEP as noted above, suggests that the Examiner believed that the Crabb patent application was being referenced only for the purpose of incorporating non-essential material, i.e. not for incorporating essential mat ter such as a heating system. The MPEP does allow an incorporation by reference for non-essential material.

In ruling on Applied’s prior motion for summary judgment on its best mode defense, this court held that ASM’s reference to the Crabb patent application in the ’464 patent was inadequate to disclose the best mode because the literal language of the MPEP prohibits incorporation by reference of essential material to anything other than an issued U.S. patent or an allowed U.S. patent application for which the issue fee had been paid, neither category of which covered the Crabb patent application at the time of the filing of the ’464 patent.

Applied now argues that that ruling by this court is “law of the case.” The court rejects Applied’s argument because statements made in an order denying a motion for summary judgment are not issues deemed established for trial unless the court so specifies.

Although the MPEP literally prohibits an incorporation of essential material by reference to a co-pending patent application, there is some case law which suggests that under certain circumstances such an incorporation by reference may be adequate to satisfy statutory disclosure requirements. The incorporation by reference of material necessary for adequate disclosure under section 112 has never been permitted for material which is unavailable to the public. Quaker City Gear Works, Inc., et al. v. Skil Corp., 747 F.2d 1446, 1455 (Fed.Cir.1984). Such was the ease in In re Hawkins, 486 F.2d 569 (C.C.P.A.1973), wherein a patentee attempted to incorporate by reference essential material from pending foreign [British] patent applications which were not readily available to either the Examiner or the public. In that case, however, the patentee cured the defect, in accordance with the MPEP, by inserting all the material from the foreign patent applications into the pending U.S. patent application prior to its issue. Unlike In re Hawkins, however, there is no serious dispute in this case that the Examiner had access to the co-pending Crabb application during his examination. This is evidenced by the fact that the Examiner himself inserted the Crabb patent number upon its issue on the face of the ’464 patent application. Moreover, the Crabb patent issued prior to the issuance of the ’464 patent. Therefore, the Crabb patent was available to the public at the time of issuance of the ’464 patent. The United States Court of Customs and Patent Appeals (“CCPA”) stated in In re Hawkins that “the function of section 112 in ensuring complete public disclosure is only violated if the disclosure is not complete at the time it is made public.” In re Hawkins, 486 F.2d at 574 . Consequently, the allowance of the incorporation of the Crabb patent application into the ’464 patent in this case does not appear to subvert the underlying purpose of section 112.

Even assuming, without deciding, that the Crabb patent application was sufficiently incorporated into the ’464 patent despite the lack of literal compliance with the MPEP, the best mode disclosure is inadequate. The ’464 patent specification refers to the Crabb patent application in three places:

The specification refers the reader twice to both the Crabb and Ozias patent applications for the type of reactor to be used. The Ozias patent teaches an improved reaction chamber without mention of any heating mechanism in its specification. Ozias does describe various heating methods including RF in its background of invention. Crabb teaches a new and improved chemical vapor deposition system which specifically incorporates the use of the reactor disclosed in the Ozias patent application and also specifically incorporates a radiant heating system fully disclosed in yet another eo-pending application. The third reference to Crabb relates only to an interlock which teaches nothing about the preferred heating method. Reading the specification as a whole, in light of what the inventors knew at the time of filing, the court finds that the reference to Crabb, which could reasonably be read as only a reference to the reactor disclosed in Ozias and to the non-heat related interlock, is such a poor quality disclosure of radiant heating as the best mode for the ’464 process as to effectively result in its concealment.

IV. ORDER

For the foregoing reasons, the court grants defendant’s motion for summary judgment for best mode violation.

. The importance of such temperature uniformity was noted in this court’s prior opinion. Inventor Olsen testified at deposition: Q. In using the process of claim 1, for the purpose for which it would be intended, i.e., epitaxial depositions, is temperature uniformity important? A. Extremely. Reines Suppl.Decl. (1994) Ex. A at 153. Inventor Hawkins also testified that temperature uniformity was important “[d]uring portions of the process,” “[d]uring deposition,” and "[d]uring temperature ramps.” Reines Decl. (1994) Ex. D at 159. ASM general manager Ferro testified at a previous trial between these parties that the '464 design team’s "purpose was to create a more uniform temperature in the wafer." Reines Decl. (1994) Ex. G at 528. . This rule is now expressly set forth in Civil Local Rule 56-3 which came into effect after the date of the court’s prior order. However, the rule is consistent with practice before the adoption of the rule. . As noted earlier, however, the Examiner may not have viewed the reference to the Crabb patent application as being for the purpose of incorporating a heating system into the best mode description in the '464 patent.
