    “For example, with respect to the CRC protocol, Dr. Kakaes testifies that “CRCs are often referred to as ‘error detecting codes’ as they are typically used[] to detect whether a received data message is or is not erroneous.” Ex. 1002 ¶ 88. Dr. Kakaes further testifies that [t]o use a CRC, the transmitter runs a polynomial division of the data block (before forward error correcting code has been applied, if any) to calculate a “remainder” consisting of a predetermined number of bits, for example 16, which are also called “parity bits,” or “check bits,” or “checksum bits,” or “CRC bits” that are attached to the block to be encoded and then transmitted, in whichever way it may or may not be encoded, punctured, etc. After reception and channel decoding (recall that means determining the “maximum likelihood” message), the receiver then runs the same polynomial division of the received decoded data block (which includes the parity bits) and, if the result does not match the “remainder,” i.e., the “parity bits” are not consistent with the determined message, the decoded data block “fails” the “check,” i.e., is declared as being erroneous. As it turns out such a determination is never wrong. In other words, the “false negative” rate is 0. Id. (emphasis added).

    “Kuo discloses a “high efficiency light” that uses LEDs to emit light, as well as different lenses to amplify the intensity of the light emitted from the LEDs. See Ex. 1013, 1:6–9. Although Kuo focuses primarily on using its light as a traffic signal, Kuo is not limited to this embodiment and broadly claims “[a] high efficiency light.” Id. at 3:14–4:23 (Compare claim 1 directed to “[a] high efficiency light,” with claim 2 directed to use of the light of claim 1 “as a signal light”). Thus, we find that Kuo is in the same field of endeavor as the ’551 patent, i.e., LED lighting systems. that Kuo meets the “reasonably pertinent” prong of the analogous art test. KSR instructs that “familiar items may have obvious uses beyond their primary purposes, and a person of ordinary skill in the art often will be able to fit the teachings of multiple patents together like pieces of a puzzle.” KSR, 550 U.S. 398, 402 (2007). Given this instruction, the Federal Circuit has explained that when considering whether prior art is reasonably pertinent we must look beyond the primary problem the inventor was seeking to solve. See Wyers v. Master Lock Co., 616 F.3d 1231, 1238 (Fed. Cir. 2010) (explaining that in analyzing whether the prior art is reasonably pertinent we must construe the scope of analogous art “broadly”); see also Donner Tech., LLC. V.

Cir. 2020) (explaining that the “reasonably pertinent” analysis must look to all of the problems to which the claimed invention relates, and must not be analyzed so narrowly as to effectively collapse the “field-of-endeavor and reasonablepertinence inquiries”). Here, although the ’551 patent is primarily focused on ways to efficiently drive LEDs using AC power, the ’551 patent is also concerned with methods of assembling an LED lighting system, including the use of: an insulating substrate, a heat sink, a reflective material on which to mount the LEDs, a lens for directing light, and a light changing or enhancing substance(s). Ex. 1001, 5:6–31, code (54) (noting that the ’551 patent is directed to both AC LED drive methods and an apparatus). Kuo expressly discloses the design of a housing that uses a lens and a light reflecting surface to maximize the light obtained from LEDs. These disclosures are reasonably pertinent to at least one problem the ’551 patent was intended to solve, e.g., what techniques and materials should be used to construct an analogous art to the ’551 patent under both prongs of the analogous art test.” slip op. at 15

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

    “[t]he words of a claim are generally given their ordinary and customary meaning as understood by a person of ordinary skill in the art when read in the context of the specification and prosecution history.” Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012) (citing Phillips, 415 F.3d at 1313). “There are only two exceptions to this general rule: 1) when a patentee sets out a definition and acts as his own lexicographer, or 2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution.” Id. (citing Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1580 (Fed. Cir. 1996)). Neither of those exceptions apply here, and for the reasons below, we disagree with Patent Owner that the plain and ordinary meaning of “selecting a filter to apply” excludes determining whether or not to apply a given filter. We begin with the claim language at issue. TQ Delta, LLC v. DISH Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). When considering the language of the claim overall, the usage of “selecting a filter” in the claims does not in any way indicate whether the filter has to be selected from among multiple filters. Claim 1 recites “selecting a filter to apply to determined level of detail.” Ex. 1001, 13:20–22 (emphasis added). Patent Owner argues that “the claim language confirms that ‘selecting a filter’ means choosing from a number of alternative filters, not merely deciding whether or not to apply a filter,” (PO Resp. 34), but we see nothing in the claim language that suggests such a requirement. Patent Owner also points us to claim 19, arguing that selecting is not merely deciding whether to apply a filter, “since that determination is already made in [c]laim 19 by virtue of the initial sub-step of ‘exceed[ing] the threshold.’” Id. Again, we see nothing in claim 19 that suggests the determination of the threshold being exceeded requires a specific manner of filter selection. Instead, similar to claim 1, claim 19 recites: “when the level of detail exceeds the threshold, selecting a filter to apply to predetermined pixels.” Ex. 1001, 16:8–9. Thus, we are not persuaded that the claim language necessarily requires selecting a filter from among multiple filters. slip op. at 14

    “because Vehviläinen performs additional analysis before selecting a moderate or high activity filter, it does not teach selecting from among multiple filters. As discussed above, we do not agree with Patent Owner’s claim interpretation, and even if we did, we are persuaded that a person of ordinary skill in the art would have easily modified Vehviläinen’s filter selection to use a single area, e.g., the smooth area of Figure 5A, and a decision branch based on the level of detail for that single area. Vehviläinen discloses that “increasing the amount of selection branches makes the system more adaptive to the nature of the blocking effect but also increases control logic.” Ex. 1004, 8:15–27. Vehviläinen states that “[a] good embodiment,” but of course, “the invention can be utilized with less than three branches.” Id. at 8:18–21. Dr. Bove testifies that a person of ordinary skill in the art “would have been motivated to reduce complexity and the required control logic by using fewer branches, as taught by Vehviläinen, including for example just one branch, particularly for applications running on performance-constrained platforms such as low-end computer processors or mobile platforms, which often had constraints on thermal dissipation, power consumption, and cost.” Ex. 1003 ¶ 120 (citing Ex. 1004, 11:7–22). He further testifies that a person of ordinary skill in the art “would have been motivated to determine the level of detail for just the ‘smooth’ area and then select the smooth filter, if the area is smooth, or the high-activity filter otherwise.” Id. Dr. Bove illustrates that modification with the following pseudocode: if ( IsSmooth (Figure_5A) == TRUE) { Select (SmoothFilter); } else { Select (HighActivityFilter); } Id. He further testifies that such a modification would have been obvious and well within [a person of ordinary skill in the art’s] level of skill, and [such a person] would have had a reasonable expectation of success given that [the] modification involves a simple reordering of elements taught by Vehviläinen, the fact that Vehviläinen expressly teaches the have had with these basic filtering and thresholding techniques. Id. On this aspect, we credit Dr. Bove’s testimony because it is based on the express teachings of Vehviläinen and addresses a straightforward modification in view of those teachings.” slip op. at 33

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner

    “a) Patent Owner Has Not Established that It is Entitled to a Presumption of Nexus We determine that Patent Owner has not demonstrated a nexus between the evidence presented and claims 1 and 17–19. Patent Owner’s arguments and evidence are directed broadly to the DivX6 codec’s deblocking scheme and not specifically to the deblocking aspects covered by the challenged claims. We agree with Petitioner that the claimed features constitute only a small part of the commercial product and the two are far from being coextensive. See Pet. Reply 31 (citing Ex. 1017, 133:10–24; Ex. 1018, 34:4–35:1). As Dr. Bajaj explained, the “DivX [codec] included a lot of things” other than deblocking, and the DivX documentation details “only a fraction of the things that were there in the codec.” Ex. 1017, 133:10–24.” slip op. at 48

    “understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 13, 17. Petitioner asserts that [a] person of ordinary skill in the art (“POSITA”) . . . would have had a bachelor’s degree in electrical engineering, or similar technical field, with two years of relevant experience in the field of design and/or development of LEDs and circuits in the context of lighting control systems. An increase in experience could compensate for less education. Pet. 9 (citing Ex. 1002 ¶ 35). Patent Owner does not dispute the level of skill in the art. See PO Resp. 32 (referring to, but not disputing, Petitioner’s proposed level of skill).

    “2. “a switch configured to enable user selection” Prior to Institution, Patent Owner asserted that Petitioner applied an incomplete claim construction of the phrase “a switch configured to enable user selection.” Prelim. Resp. 19–22. Patent Owner contended that the switch must be “physical” and that a user must “be able to directly select an outcome.” Id. at 19. Our Institution Decision preliminarily construed “a switch configured to enable user selection of the different color temperatures of light” to permit a user to select the color temperature through direct or indirect use of the switch. Dec. 21. Patent Owner no longer disputes the construction of this term and applies our preliminary construction in its Response. PO Resp. 6.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

    “We view Petitioner’s combination to be sufficiently clear, setting forth sufficiently “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418. Petitioner explains that “Grajcar discloses a switch (switch 2115) configured to enable user selection” and that “[t]o the extent [Patent Owner] argues that switch 2115 does not explicitly show ‘a switch configured to enable user selection,’ it would have been obvious to modify Grajcar by adding a switch that allows user input, as taught by Walter.” Pet. 26–27 (citing Ex. 1004, ¶¶ 107, 102–112, 192–195, Fig. 21; Ex. 1002 ¶¶ 72–73). This combination would have involved “integrat[ing] the LED circuits and switch of [Grajcar] Figure 21 with the LED bulb disclosed in Walter.” Id. at 21 (emphasis added). That is, the proposed combination simply aims to use Grajcar’s LED circuit in Walter’s bulb, so that Walter’s switch may actuate Grajcar’s LED circuit. See id. at 21–23, 27. Petitioner confirmed this position at the oral hearing, explaining, “so the proposed combination, looking again at Slide 13, it’s taking all of the circuits in [Grajcar] Figure 21 and putting them into the bulb of [Walter] Figure 2 where any user selection of color temperature is done using [Walter’s] Switch 170.” Tr. 11:20–23. Not only is Petitioner’s proposed combination sufficiently clear, but by arguing that Petitioner provides no “explanation of how the resulting combination would operate” or “what specific elements of Walter would be incorporated into Grajcar,” Patent Owner essentially attacks the Petition for not explaining how to bodily incorporate Grajcar into Walter. But “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . 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)). Patent Owner’s bodily incorporation argument fails to undermine Petitioner’s persuasive showing. In any event, Petitioner contends, and Patent Owner does not dispute, that “[i]t would have been well within the skill of a POSITA to implement Grajcar’s LED light with the user interface of Walter,” as “[t]he circuits described in Grajcar and claimed in claim 1 are extremely basic.” Pet. 23; see also Ex. 1002 ¶ 66 (Dr. Lebby testifying the same).” slip op. at 15
