  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

    “I agree with Petitioner that Patent Owner’s Remand Brief, specifically pages 1–7, attempt to address aspects of claim 1 for the first time on remand. I also agree that Patent Owner’s arguments attempt to recharacterize limitations [j] and [k] to raise issues that Patent Owner did not raise previously, in contravention of our Order that issues raised needed support from “where those issues were raised in previous briefings by the parties.” Paper 56, 2. I have addressed whether scalability and FEC are integral to how Chen operates above, as well as whether the Petition relies on those aspects, supra. The questions about how Chen operates and what portions of Chen are asserted in the ground of unpatentability were previously raised, but now are being considered or reconsidered, based on the Federal Circuit’s decision. In Patent Owner’s Remand Brief, pages 1–7, the citations to argument previously raised do not support the arguments now presented by Patent Owner on remand.

    “7 Patent Owner’s Brief on Remand recognizes that there are two arguments Patent Owner raised in its Patent Owner Response that were not addressed in the Final Written Decision. See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit. See Paper 52. Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1. Petitioner requests sanctions because of the impropriety of Patent Owner’s remand brief, including new claim construction arguments for limitations [1j] and [1k], and prejudice to Petitioner.

    “We agree with Patent Owner. The Petition is required to identify “[h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104(b)(3). Petitioner argued in the Petition that “as properly construed, the claimed ‘first parameter,’ ‘second parameter,’ ‘third parameter,’ and ‘fourth parameter’ are four different parameters.” Pet. 17–18. In the Institution Decision, Petitioner prevailed on that point and “we agree[d] with Petitioner that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels.” Dec. 14. Patent Owner “relie[d] on the Board’s construction ‘that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels,’” and proposed distinct parameters in the Specification that it alleges are examples of second and third parameters, albeit not the same two parameters proposed by Petitioner. PO Resp. 9, 29. Petitioner now proposes new constructions for the second and third parameters that would limit those parameters to the two examples it advanced in the Petition and improperly supports these new constructions with new expert testimony and an exhibit from the prosecution of a later patent. Reply 20–25; Ex. 1040 ¶¶ 20–29; Ex. 1038. See also Consolidated Trial Practice Guide (“TPG”)10 73 (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”). As Patent Owner observes (Sur-reply 10 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. 21), it has no opportunity to introduce rebuttal evidence contesting the new constructions. See TPG 73–74 (Nov. 2019) (“The sur-reply may not be accompanied by new evidence other than deposition transcripts of the crossexamination of any reply witness. Sur-replies should only respond to arguments made in reply briefs, comment on reply declaration testimony, or point to cross-examination testimony.”). We agree with Patent Owner that it would be unfair to consider Petitioner’s new construction. See 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.”). Thus, Petitioner has forfeited its new claim construction arguments and they will not be considered. See TPG 74 (“While replies and sur-replies can help crystalize issues for decision, a reply or sur-reply that raises a new issue or belatedly presents evidence may not be considered.”). Moreover, these arguments would be unpersuasive even if considered. Petitioner has, at most, cited description in the Specification to show that its identified second and third parameters are examples corresponding to the recited second and third parameters. Ex. 1005 ¶¶ 84–95. This description does not define the second and third parameters nor purport to exclude from the claims any parameter that would otherwise meet the language of the claims. The prosecution history to which Petitioner cites, that of a child application, took place after the prosecution of the ’466 patent and thus, does not constitute a definition or disclaimer of subject matter for claims of the ’466 patent. In any case, the brief argument in the cited response to office action, that “[i]n the algorithm, the first value is provided by the wireless network for each of a plurality of buffers where the buffer having the second value above a threshold transmits data first,” does not define the second and third parameters, disavow any values from those parameters, or even discuss the third parameter. Ex. 1038, 12. Petitioner’s extrinsic evidence, Dr. Akl’s testimony, does little more than repeat the arguments in the Reply and, thus, is of little value. Ex. 1040 ¶¶ 20–29. In sum, we maintain our construction that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels. Under this construction, RAAUq” and RAAUq’, respectively, could potentially be second and third parameters, as could RAAUq’ and RAAUq”, respectively, as long as they satisfy the rest of the pertinent language of the challenged claims.” slip op. at 15

    “production, we still would find that a skilled artisan would not have been able to ascertain from the disclosure in the ’421 application that RAAUq’ could take values less than zero. Instead, even if we were to credit Dr. Lomp’s testimony, to conclude that RAAUq’ can take negative values, a skilled artisan would need to program computer software to simulate the ’421 application’s algorithm and correctly choose starting parameters and other context variables without guidance from the description in the ’421 application. This case is similar to that in New Railhead, where the written description was insufficient because “one of ordinary skill in the art must first make the patented invention before he can ascertain the claimed features of that invention.” 298 F.3d at 1295. This case also is similar to Los Angeles Biomedical Research Institute, in which an application’s written description was insufficient because assumptions and starting variables were not knowable from the disclosure in the application. 849 F.3d at 1058. Thus, even if we were to conclude that Patent Owner has met its burden of production, a preponderance of the evidence shows that the ’421 application does not provide written description support for Alternative A. In sum, we conclude that the ’421 application does not provide written description support for the challenged claims and that, therefore, Speight is prior art to the challenged claims.” slip op. at 41

Google, 34 F.4th at 1088. Cheyer’s and Martin’s testimony that Dr. Moran’s role was administrative and non-technical with respect to the core infrastructure of OAA is belied by a separate article describing OAA that includes the facilitator and lists Dr. Moran as the lead author. Ex. 1174, 1–2, 4. Indeed, the OAA article lists Dr. Moran and Mr. Cheyer as authors but excludes Mr. Martin. Id. Although Mr. Cheyer disagrees with the article’s description of the origins of OAA and the facilitator (Ex. 2037, 78:23–79:12 (Mr. Cheyer asserting that he “would not agree in the characterization of Open Agent Architecture grew out of [earlier] works” as described in the article)), Mr. Cheyer admits patent]” (id. at 1088), “which is a continuation-in-part of the application that resulted in the ’115 patent” (id. at 1086). in his deposition that Dr. Moran was extremely technical, and probably made technical contributions to OAA (id. at 34:1–20, 64:16–20, 102:2–4).

When viewed in light of Dr. Moran’s status as a joint inventor on the closely related ’931 patent (Ex. 2002, code (75)) and as a lead author of the substantive paper that discusses OAA’s early development, we find Mr. Martin’s and Mr. Cheyer’s admissions—that Dr. Moran made technical contributions to OAA—undermine their testimony that Dr. Moran’s inclusion as an author on the Martin reference was a matter of administrative respect and not a result of a technical contribution. See PO Remand 11; PO Resp. 50–51. Indeed, we find Cheyer and Martin’s general description of Dr. Moran—as an administrator without technical contributions to the Martin reference—is not supported by the full record, which instead supports Dr. Moran’s contributions to technical work that involves the Martin reference, such as contemporary papers and the ’931 patent. See, e.g., Ex. 1174, 2002.

In addition, Dr. Olsen testified, the proposed implementation “would have been a mere combination of known components and technologies . . . , according to known methods, to produce predictable results.” Ex. 1002 ¶ 87.

    “Dr. Mowry testifies that, “[g]iven these difficulties in using handheld devices to capture suitable images, a person of ordinary skill in the art would have been motivated to implement Acharya using the reference lines and capture techniques described in Luo in order to achieve a high likelihood of obtaining images that were suitable for image processing.” Ex. 1002 ¶ 63. According to Dr. Mowry, Luo’s solution is “directly applicable to capturing check images to predictably increase the likelihood of obtaining images that are suitable for” optical character recognition. Id. Dr. Mowry’s testimony is consistent with the express disclosures in Acharya and Luo and, therefore, is credible. Acharya expressly identifies technology that it uses to capture information from documents, namely optical character recognition, and Luo expressly describes a technique designed to reduce projective distortion when capturing an image of a document, such that optical character recognition can be performed more accurately. Dr. Creusere admitted on cross-examination that “correcting geometric distortion will make it easier to perform automatic text recognition.” Ex. 1037, 89:1–2. Petitioner contends that its proposed combination would have amounted to applying a known technique to a known device ready for improvement to yield predictable results. Pet. 32–34; see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 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.”); Ex. 1002 ¶ 64 (“Implementing Acharya’s RCT using Luo’s camera system would have simply involved applying a technique that was known to a device that was known and ready for improvement, to yield predictable results.”). We agree. This appears to be a textbook example of using a technique that improved one device to improve a similar device in the same way. As we preliminarily observed in the Institution Decision (Dec. 54), a combination of Acharya and Luo would have been no more than “[t]he combination of familiar elements according to known methods” and, thus, likely obvious because it “does no more than yield predictable results.” KSR, 550 U.S. at 416.” slip op. at 30

    “Acharya’s system would have imposed “additional processing overhead and complexity on the customer’s device as compared to the existing manual capture system” and that “[t]his type of processing, especially when done in real-time, was considered computationally-intensive in 2009.” PO Resp. 53 (citing Ex. 2115 ¶ 35). The only evidence Patent Owner offers to support this assertion is the testimony of its expert, who largely copies Patent Owner’s argument and does not identify the basis for the testimony. As such, the testimony is entitled to little weight. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Velander v. Garner, 348 F.3d 1359, 1371 (Fed. Cir. 2003) (“It is within the discretion of the trier of fact to give each item of evidence such weight as it feels appropriate.”); Ashland Oil, Inc. v.

Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value in a validity determination.”). We note that Luo describes its technique as implemented on conventional computing equipment on portable devices available prior to 2009 without mention of concerns over processing overhead. Ex. 1004, 8. Patent Owner’s evidence is insufficient to establish that concerns over processing overhead would have dissuaded a skilled artisan from pursuing a combination of Acharya and Luo.” slip op. at 44

Moreover, Patent Owner provides no basis for its assumption that monitoring an actor’s diabetic condition involves stored facts, such as symptomatic blood sugar levels, that are specific to the individual as opposed to broadly-based criteria applicable to diabetic patients in general.

Pet. 44–46 (citing Young Decl. ¶¶ 115–120). Claim 11 depends from claim 1, and additionally requires “formulating a response plan for responding to the at least one emergency situation.” Ex. 1001, 12:60–62. Claim 13 depends from claim 11, and additionally requires “wherein formulating the response plan includes selecting at least one responder from a plurality of designated responders.” Ex. 1001, 12:65–67.

    “Proof of conception must be by “corroborating evidence which shows that the inventor disclosed to others his ‘completed thought expressed in such clear terms as to enable those skilled in the art’ to make the invention.” Coleman v. Dines, 754 F.2d 353, 359 (Fed. Cir. 1985) (citing Field v. Knowles, 183 F.2d 593, 601 (CCPA 1950)); see also Mahurkar v. C.R. Bard, Inc., 79 F.3d 1572, 1577 (Fed. Cir. 1996) (corroboration requirement “arose out of a concern that inventors testifying in patent infringement cases would be tempted to remember facts favorable to their case by the lure of protecting their patent or defeating another’s patent”). Similarly, an inventor’s testimony alone is insufficient to establish an earlier reduction to practice. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1169–71 (Fed. Cir. 2006). Instead, a party seeking to prove an actual reduction to practice must proffer evidence corroborating that testimony. Id. at 1170. The sufficiency of corroboration is determined according to a “rule of reason.” Price v. Symsek, 988 F.2d 1187, 1195 (Fed. Cir. 1993). This, however, does not dispense with the requirement that some independent evidence provide corroboration. Coleman, 754 F.2d at 360. The requirement of “independent” corroboration requires evidence other than the inventor’s testimony. In re NTP, Inc., 654 F.3d 1279, 1291–92 (Fed. Cir. 2011). 3. Discussion We find that Patent Owner has not met its burden of establishing that Mr. Kuster conceived and reduced to practice his invention prior to the filing dates of Hsiao or He. By itself, Mr. Kuster’s testimony is insufficient to establish that he reduced his invention to practice prior to the November 23, 2010, filing date or Hsiao or the June 2, 2010, filing date of He. “Throughout the history of the determination of patent rights, oral testimony by an alleged inventor asserting priority over a patentee’s rights is regarded with skepticism, and as a result, such inventor testimony must be supported by some type of corroborating evidence.” Woodland Tr. v. Flowertree Nursery, Inc., 148 F.3d 1368, 1371 (Fed. Cir. 1998) (quoting Price, 988 F.2d at 1194).

    “We do not agree with this argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Moreover, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” so the fact that it would take some creativity to carry out the combination does not defeat a finding of obviousness. KSR, 550 U.S. at 421; see also ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1219 (Fed. Cir. 2016) (“The rationale of KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B.”). We find there is support for making this combination of He and Cheng in the testimony of Dr. Baker that addition of a controller is “conventional” in USB flash drives. Baker Decl. ¶ 167. We find that for the reasons given by Dr. Baker, a person of ordinary skill would have added a controller to He. We determine that the combination of He and Cheng teaches each limitation of claim 11.

    “attorney argument, not evidence.” Pet. Reply 26. We agree. Patent Owner does not back up its argument with testimony or other credible evidence. To demonstrate long-felt need, a patentee must point to an “articulated identified problem and evidence of efforts to solve that problem” which were, before the invention, unsuccessful. Tex. Instruments v. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). All Patent Owner proves, if anything, is that after the USB 3.0 specification issued, a number of companies rushed in to provide contacts that met the new standard. Patent Owner does not demonstrate that they failed where Mr. Kuster succeeded. In fact, there is no evidence that Mr. Kuster ever commercialized his invention.8 8 Victorinox never paid for the work Mr. Kuster did on the USB 3.0 memory device, and to Mr. Kuster’s knowledge, never marketed the product. Kuster Dep. 22:21–24:13. Patent Owner contends “Mr. Kuster’s invention filled the existing need for a durable yet slim USB flash drive compatible with USB 3.0 that was easy to manufacture.” PO Resp. 77. But instead of presenting independent evidence of failure of the others to solve known technical or manufacturing problems, Patent Owner relies on generalized statements concerning the need for USB 3.0 connectors and solutions by others that Patent Owner contends have not been successful. PO Resp. 74–77. We are not persuaded by Patent Owner’s argument that Mr. Kuster’s alleged invention filled a long-felt need where others failed.” slip op. at 29
