EDWARD M. CHEN, District Judge.
Plaintiff Trans Video Electronics, Ltd. has filed suit against various Sony entities (collectively "Sony"), asserting a claim for infringement of one of its patents, more specifically, Patent No. 5,991,801 (the "'801 patent"). On May 18, 2011, 2011 WL 1884358, Judge Patel issued a claim construction order in which she construed various terms contained in the only claim at issue, i.e., claim 3. See Docket No. 119 (order). Based on that construction, Sony has now moved for summary judgment, asking that the invention claimed be deemed invalid for lack of a written description. Having considered the parties' briefs and accompanying submissions, as well as the oral argument of counsel, the Court hereby
The '801 patent relates to an information distribution system for a digital network. As stated in the patent:
'801 Patent, col. 1:11-17.
As Judge Patel noted in her claim construction order, the specification for the '801 patent discloses two embodiments, represented by Figures 1B and 5, respectively.
In
On the other end, the video menu unit (504) referenced above is coupled to a telephone line unit (508) (which corresponds to the distribution amplifier/equalizer (112) of Figure 1B). The telephone line unit (508) has a plurality of output lines (514) which in turn are coupled to a plurality of menu CSU/DSU units (516). The menu CSU/DSU units (516) are in turn coupled to the network (520). See '801 Patent, col. 6:31-40.
Video news distribution in the above system described in Figure 5 operates as follows. Users at television stations or at newspaper or magazine printing houses (550A-C) use their computers (555A-C) to dial the telephone number of the video menu unit (504). The connected user views a menu listing the various clips available on the video clip storing units (525A-H). If the user wishes to obtain a particular clip, he or she enters a command to the video menu unit (504), which in turn sends a "request-to-send" command to the appropriate video clip storing unit (525A-H). See '801 Patent, col. 6:66-7:4-10. The video clip storing unit then sends the video clip to the user (550A-C) via its corresponding distribution amplifier/equalizer (531A-H), via one of the corresponding CSU/DSU units, which in turn is coupled to the network (520). See '801 Patent, col. 6:51-65, 7:10-13, Fig. 5.
While the '801 patent contains multiple claims, the only claim at issue in the instant case is claim 3.
'801 patent, col. 8:19-55 (emphasis added).
As indicated by the language bolded above, claim 3 requires that the master communications unit receive a synchronous digital signal and then relay that same signal to the digital amplifier units. In turn, each digital amplifier unit splits up that same signal into a plurality of synchronous signals. At the hearing on the instant motion, both parties agreed that the term "said" as used to describe the synchronous digital signal means the "same."
In her claim construction order, Judge Patel indicated that, in Figure 1 B, the master communications unit is the CSU/DSU (108). See Docket No. 119 (Order at 8) (discussing the embodiment disclosed in Figure 1B). As for Figure 5, she concluded that the master communications unit is a menu CSU/DSU unit (516).
Sony has moved for summary judgment pursuant to Federal Rule of Civil Procedure 56(c), arguing that, based on Judge Patel's claim construction order, there is no genuine dispute of material fact that the '801 patent is invalid because it fails to provide a written description for the invention claimed in claim 3.
Under Rule 56, summary judgment shall be rendered "if 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. 56(c). An issue of fact is genuine only if there is sufficient evidence for a reasonable jury to find for the nonmoving party. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248-49, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). "The mere existence of a scintilla of evidence. . . will be insufficient; there must be evidence on which the jury could reasonably find for the [nonmoving party]." Id. at 252, 106 S.Ct. 2505. At the summary judgment stage, evidence must be viewed in the light most favorable to the nonmoving party and all justifiable inferences are to be drawn in the nonmovant's favor. See id. at 255, 106 S.Ct. 2505.
In the instant case, Sony's claim of invalidity based on lack of a written description is an affirmative defense for which it has the burden of proof—in fact, a heightened burden of proof of clear and convincing evidence. See Titan Tire Corp. v. Case New Holland, Inc., 566 F.3d 1372, 1376 (Fed.Cir.2009) (stating that, because "an issued patent comes with a statutory presumption of validity under 35 U.S.C. § 282 . . ., an alleged infringer who raises invalidity as an affirmative defense has the ultimate burden of persuasion to prove invalidity by clear and convincing evidence"). Where a defendant moves for summary judgment based on an affirmative defense for which it has the burden of proof, the defendant "must establish beyond peradventure all of the essential elements of the . . . defense to warrant judgment in [its] favor." Martin v. Alamo Cmty. College Dist., 353 F.3d 409, 412 (5th Cir.2003) (internal quotation marks omitted;
As noted above, Sony's invalidity argument is based on a lack of written description. The written description requirement is found in the first paragraph of § 112 of the Patent Act. It provides in relevant part as follows:
35 U.S.C. § 112.
The Federal Circuit has:
Yingbin-Nature (Guangdong) Wood Indus. Co. v. ITC, 535 F.3d 1322, 1334-35 (Fed.Cir.2008) (internal quotation mars omitted). That is,
Billups-Rothenberg, Inc. v. Associated Reg'l & Univ. Pathologists, Inc., 642 F.3d 1031, 1036 (Fed.Cir.2011) (internal quotation marks omitted); see also Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1319 (Fed.Cir.2011) (stating that "[t]he purpose of the written description requirement `is to ensure that the scope of the right to exclude, as set forth in the claims, does not overreach the scope of the inventor's contribution to the field of art as described in the patent specification'").
Importantly, for purposes of the written description requirement, "[o]ne shows that one is `in possession' of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious." Lockwood v. American Airlines, 107 F.3d 1565, 1572 (Fed.Cir. 1997). The Federal Circuit has emphasized that
Id.
Because the written description requirement takes into account the perspective of a person of ordinary skill in the art, the Federal Circuit has noted that "[the] inquiry [regarding written description] is a factual one and must be assessed on a case-by-case
However, a written description decision can turn simply on a claim construction. See id. at 1319-20 (in upholding summary judgment of invalidity based on lack of written description, rejecting the patent holder's "contention that the district court's claim constructions denied it the opportunity to demonstrate specification support or proffer expert testimony [as] [i]t should have been clear to Katz that the construction of the claims was important to the written description analysis"); University of Rochester v. G.D. Searle & Co., 358 F.3d 916, 927 (Fed.Cir.2004) (noting that, "although compliance with the written description requirement is a question of fact, [the patent holder's] argument that a patent may not be held invalid on its face is contrary to our case law"; citing a prior holding that "a patent can be held invalid for failure to meet the written description requirement, based solely on the language of the patent specification" because, "[a]fter all, it is in the patent specification where the written description requirement must be met"); cf. Harari v. Lee, 656 F.3d 1331, 1342 (Fed.Cir.2011) (stating that "[t]his written description decision turned almost entirely on the claim construction").
In its motion, Sony argued that there is a lack of written description for the invention claimed in claim 3 because, based on the specification, the only possible description for the invention is Figure 5 and it does not include a description of the synchronous digital signal—a command signal, and not video—being split up into a plurality of synchronous signals. See, e.g., Mot. at 12. At the hearing on the motion, Sony expanded on this argument, noting that Figure 5 cannot describe the invention claimed in claim 3 because claim 3 requires that the same synchronous digital signal be received by the master communications unit and passed on to the distribution amplifier units but Figure 5 describes a command signal (i.e., not video) being received by the master communications unit (516) and a video clip being sent on to the distribution amplifier units (531A-H).
The Court finds both arguments persuasive. As a preliminary matter, it agrees with Sony that Figure 5, and not Figure 1B, contains the critical description in the specification. Figure 1B cannot provide the written description because, e.g., it does not contain anything that would constitute a menu storing unit or a video clip storing unit, both of which are elements of claim 3. Figure 1B does have backup units (134, 136), but the specification does not deem them the same or identical to the video clip storing units. See '801 Patent, col. 6:41-43 (noting that "[v]ideo news distribution system 500 includes a plurality of units 525A-525H similar to backup units 134 or 136 of FIG. 1B") (emphasis added). Compare '801 Patent, col. 54-56 (stating that "[d]istribution amplifier/equalizers 531A-531H are identical to distribution amplifier/equalizer 112 previously discussed") (emphasis added).
With respect to claim 3, the Court also agrees with Sony that the language of the claim makes clear that a master communications unit must receive a synchronous digital signal and then passes that same signal ("said . . . signal") to the distribution amplifier units, each of which in turn divides the same signal ("said . . . signal")
The Court further agrees with Sony that Figure 5 does not describe the invention claimed in claim 3. Per the specification, in Figure 5, a video menu unit (504) receives a command (i.e., not video) from a user (550A-C). Because Judge Patel concluded that the menu CSU/DSU units (516) are the master communications units, and because the menu CSU/DSU units (516) connect the video menu unit (504) and the user (550A-C) (through the network (520)), the menu CSU/DSUs (516) must also receive that same command (i.e., not video) from the user (which it then passes on to the video menu unit (504)). Therefore, as described, in Figure 5, the synchronous digital signal that is received by the master communications unit (516) is a command (and not video). The problem for Trans Video is that there is nothing in the specification in Figure 5 that describes that command then being split into a plurality of signals, as claim 3 specifies. Furthermore, the specification talks about the distribution amplifier/equalizers (531A-H) receiving and sending out a video clip (and not a command). See '801 Patent, col. 7:10-13 (stating that "[t]he video storing unit with that video clip or photograph then sends the video clip (photograph) via its corresponding distribution amplifier/equalizers 531A-531H via one of its corresponding CSU/DSU units 535A-535H"). But claim 3 requires that the same synchronous digital signal be received by the master communications unit and then passed on to the distribution amplifier units. In Figure 5, a command is received by the master communications unit (516) but then the distribution amplifier/equalizers (531A-H) receive a video clip.
Indeed, at the hearing, Trans Video admitted that neither Figure 1B nor Figure 5 alone describes the invention claimed in claim 3. Although during the claim construction hearing before Judge Patel, Trans Video had argued that "FIG. 5 contains all the elements recited in claim 3," Docket No. 114 (Reply at 6), Trans Video now takes the position that a person of ordinary skill in the art would have combined elements from Figure 1B and elements from Figure 5 to arrive at the invention claimed in claim 3. Trans Video pointed out, for example, that, in Figure 1B, the master communications unit (108) does receive video (instead of a command signal). See '801 Patent, col. 4:59-60 (stating that "[t]he compressed video news clip is input to master CSU/DSU 108"). Thus, according to Trans Video, a person of ordinary skill in the art would have taken the master communications unit (108) from Figure 1B with the remaining elements in Figure 5 to arrive at the invention claimed in claim 3. As another example, Trans Video argued that a person of ordinary skill in the art would have incorporated the video clip storing units (and implicitly the video menu unit) from Figure 5 into the embodiment in Figure 1B to come up with the invention claimed in claim 3.
Trans Video's argument, however, runs counter to Federal Circuit case law.
Trans Video's contention that a person of ordinary skill in the art would have understood that elements of Figures 1B and 5 could be combined is essentially an argument of obviousness. But as noted above, the Federal Circuit has specifically stated that, for purposes of the written description requirement,
Lockwood, 107 F.3d at 1572 (emphasis added and omitted). The written description requirement thus differs from the question of obviousness. Cf. Boston Sci. Scimed, Inc. v. Cordis Corp., 554 F.3d 982, 991 (Fed.Cir.2009) (finding invention claimed invalid based on prior art; holding that a person of ordinary skill in the art would have been motivated to combine two figures/embodiments in a prior patent to arrive at the invention claimed, thus rendering the invention obvious).
The authorities cited by Trans Video is not to the contrary. These cases merely note that "a claim need not be limited to a preferred embodiment," Lampi Corp. v. Am. Power Prods., 228 F.3d 1365, 1378 (Fed.Cir.2000) embodiment"); see also Rexnord, 274 F.3d at 1344 (noting that "an applicant is not required to describe in the specification every conceivable and possible future embodiment of his invention"; adding that, "[i]f structural claims were to be limited to devices operated precisely as a specification-described embodiment is operated, there would be no need for claims"); SRI Int'l v. Matsushita Elec. Corp., 775 F.2d 1107 (Fed.Cir.1985) (stating that, "if structural claims were to be limited to devices operated precisely as a specification-described embodiment is operated, there would be no need for claims"), and that "a patent claim is not necessarily invalid for lack of written description just because it is broader than the specific examples disclosed." Martek Biosciences Corp. v. Nutrinova, Inc., 579 F.3d 1363, 1371 (Fed.Cir.2009). The Court does not take issue with these general principles. But these cases fail to address the specific issue here—i.e., whether the written description requirement may be met where the combination of elements comprising the invention is not described at all and instead requires a person of
Finally, the Katz declaration that Trans Video has submitted in support of its opposition does not alter the Court's conclusion. According to Trans Video, at the very least, summary judgment is inappropriate because written description is a factual inquiry and it has raised a genuine dispute of material fact by submitting a declaration from an expert (Randy H. Katz). But, as discussed above, a written description decision can turn simply on a claim construction. Here, Dr. Katz's opinion essentially contradicts Judge Patel's claim construction. Most notably, in paragraph 16 of his declaration, he states:
For the foregoing reasons, the Court grants Sony's motion for summary judgment.
Although this motion resolves the only claim at issue in the case, the Court shall defer entry of judgment in accordance with this opinion because Trans Video has now filed a motion to amend, seeking to add a new claim of patent infringement to the case.
This order disposes of Docket No. 124.
IT IS SO ORDERED.
