“Both parties rely on the language of claim 1 and the ’294 patent specification to support their respective constructions, and they emphasize that a user’s selective triggering of the control device does not issue different activation commands or control which data conveyance operation is used. Claim 1 recites an “invariable activation command” as a command that is “issued when said control device is selectively triggered by the user.” selectively trigger a control device “via one of a button, a keypad, a tactile screen, and a biometric parameter detector,” e.g., by entering a PIN that is authenticated, in order for an invariable activation command to be issued. Id. at 8:43–50, 10:26–29, 19:3–5. The claimed function of an invariable activation command is to “initiate[]” either a “first data conveyance operation” or a “second data conveyance operation” depending on whether “said switching element is in said first state” or “in said second state.” As explained above, the state of the switching element depends on whether or not an “activation cue” has been received by a “cue receiver.” The ’294 patent specification confirms the operation. Id. at 10:26–36, 15:14–28. The parties joust over the proper terminology for characterizing an “invariable” activation command, but they appear to agree on how the claimed cell phone and method work. The ’294 patent specification makes clear that the activation command is “invariable” in the sense that whenever a user selectively triggers the control device on the cell phone, for example by pressing a button on a keypad, the same command is issued to initiate a data conveyance operation regardless of the “state” of the “switching element” (i.e., in a “first state” or “second state”). The user cannot select or issue different activation commands. The selection of which of the two possible data conveyance operations will be initiated by selectively triggering the control device depends not on the activation command—it is always the same—but on whether the switching element has received an activation cue (“first state”) or not (“second state”). The ’294 patent neatly summarizes that “[t]he same invariable activation command will thus be issued upon [the] control device being triggered, and it is the state of [the]” slip op. at 12

“The ’294 patent claims and specification make clear that the switching element switches between a “first state” and a “second state” depending on whether or not an activation cue is received. Ex. 1001, 9:28–41, 14:53–59. The state of the switch, in turn, “allow[s] data to be conveyed according to alternate data conveyance operations.” Id. (emphasis added). Thus, the claim limitation is recited as a “data conveyance switching element,” not a “data switch,” because the switching element allows the device to switch between alternate operations for conveying data from the cellular phone to an external data exchange device. Id. Patent Owner’s proposed construction “conflicts with the express disclosure of the ’294 Patent.” See Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner
“We preliminarily disagree with Patent Owner. Although the claim lists step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Nothing in the express claim language precludes performing step 1d before step 1b, as in Zhang. For example, the claim does not contain temporal terms, like “then” or “next,” nor does the claim otherwise specify that step 1b must precede step 1d. Although Patent Owner points out that a term of step 1d (i.e., the one more available devices) derives antecedent basis from text in step 1b (i.e., one more available devices), this alone does not directly or implicitly require performing step 1b before step 1d. Prelim Resp. 6–7 (citing Ex. 1002, 240, ’648 patent prosecution history). Nor does the Specification require performing the step of identifying devices as available before the step of wirelessly signaling those devices or even that the steps be mutually exclusive. For example, there are no statements that this step order is important, nor disclaimer of any other order, nor any prosecution history indicating a surrender of any other order. Moreover, according to the Specification, announcer 30, which is the component that identifies devices as available prior to the wirelessly signaling, is only “preferably provided.” Ex. 1001, 7:28–31. Even assuming Patent Owner were correct that step 1b must precede step 1d, Patent Owner’s position that device(s) must be identified as available does not appear to be commensurate with the claims. According to its plain meaning, limitation 1b does not appear to require identifying devices as available; the claim merely requires identifying “available devices.” See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (rejecting arguments “not based on limitations appearing in the claims”). In other words, the claim does not appear to require identifying (i.e., determining) whether devices are available but merely requires identifying devices that happen to be available. According to our preliminary understanding, Zhang’s mobile device 1) discovers (identifies) connected available and unavailable helper servers, and then 2) sends (wirelessly signals) service requests to compatible available and unavailable helper servers. Ex. 1004, 3:44–4:8, 6:51–7:13. Thus, Zhang identifies and then wirelessly signals available devices (Zhang also identifies and then wirelessly signals unavailable devices). As such, we preliminary determine that Zhang meets the claim language “identifying one or more available devices” and “wirelessly signaling the one or more available devices.”” slip op. at 18

“When construing claim terms, we first review the language of the claims. TQ Delta, LLC v. DISH Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019).

“The obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Because the prior art need not explicitly disclose or explicitly suggest the proposed modification (here, at least according to Patent Owner, making initial power and power ramping dependent on procedure type), the absence of precise teachings regarding the proposed modification does not undermine the grounds of unpatentability. Lee2 discloses initial power and power ramping functions dependent on input. Ex. 1006 ¶¶ 63, 71–74. Specifically, Lee2 discloses using, based on measured signal power (RSRP), event/distance as input for initial power and power ramping. Id. Lee2 does not, nor could it, address using procedure type as input for initial power and power ramping because Lee2 only discloses 1 type of procedure––the conventional 4-step. Ex. 1006, Fig. 3. Per Lee1, reducing from the conventional 4-step to 2-step is a development in the technology to reduce time delay. Ex. 1005 ¶ 6. Although not discussed in Lee1, the prosecution history shows that switching from 4-step to 2-step is similarly based on measured RSRP. Prelim. Resp. 39 (discussing prosecution history); Ex. 4039–40. Patent Owner’s declarant also acknowledges that there is a correlation (albeit unreliable) between RSRP and distance. Ex. 2002 ¶ 27 (“RSRP may or may not correspond to distance in the real world due to various wireless artifacts . . . .”). Accordingly, we are preliminarily persuaded that a person of ordinary skill in the art, facing the needs created by the development of new types of procedures (i.e., the 2-step), and upon recognizing the link between event/distance, procedure type, and measured RSRP, would have, in light of Lee2, seen a benefit and had a reasonable expectation of success in using initial power and power ramping functions dependent on procedure type.” slip op. at 24

“We find Patent Owner’s proposed “wireless communications” is more consistent with the ’958 patent than Petitioner’s proposed “telecommunication,” which encompasses a variety of technologies including, e.g., landline and wireless telephones, cable, and satellite. See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications). We therefore adopt a modified version of Petitioner’s proffered level of ordinary skill in the art, substituting “wireless communications” for “telecommunication.” The parties rely on expert testimony for their respective positions relating to the number of years of experience needed to attain ordinary skill, but neither expert cites supporting evidence for their testimony. See Ex. 1002 ¶ 33; Ex. 2002 ¶ 15. Our decision to institute would be the same regardless of whether the length of experience is two years or three. If the parties believe the proposed differing lengths of experience would affect the analysis of patentability in this case, they should address that issue at trial and cite to evidence in the record to support their positions.” slip op. at 6

“Based on the preliminary arguments and evidence, we disagree with Petitioner’s proposed construction requiring the corners to be rounded via a particular process because it improperly imports a process of manufacture from the Specification into apparatus claims. See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed. Cir. 2019) (citing Vanguard Prods. Corp. v. Parker Hannifin Corp., 234 F.3d 1370, 1372–73 (Fed. Cir. 2000) (“Generally, ‘[a] novel product that meets the criteria of patentability is not limited to the process by which it was made.’”)). We also preliminarily disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from 7 Pfirsch et al., US 6,541,818, issued April 1, 2003. Ex. 1011. Pfirsch’s rounded corners. Indeed, both the Examiner found and Patent Owner admitted that Pfirsch has the recited “rounded corner[s].” See Ex. 1002, 237, 302.

“We disagree at this stage. Petitioner’s rationale for combining Kobayashi with Hshieh is not solely based on Hshieh’s top view rounding being well known. Rather, Petitioner’s rationale is clearly based on express teachings in Hshieh about the benefits of top view rounding. See Pet. 54, 59 (citing Ex. 1006, 5:3–17, Figs. 6A–8B; Ex. 1003 ¶ 137); Ex. 1003 ¶¶ 122, 133. For example, Petitioner and its declarant refer to Hshieh’s teaching at column 5, lines 3–17, which states, “[i]n order to prevent the corner vulnerability where punch through weak points may be formed at the sharp corners due to a three-dimension diffusion effect . . . , the sharp corners of the polysilicon openings can be either blunted or rounded.” See Pet. 59; see Ex. 1003 ¶ 137.

“Next, Patent Owner argues that Hshieh teaches non-orthogonal parallelogram-shaped cells to increase cell packing density and “specifically identifies square cell configurations as having disadvantageous packing densities.” Prelim. Resp. 23. Patent Owner argues that Hshieh therefore “plainly teach[es] away from combining Hshieh with Kobayashi in the manner claimed.” Id. We do not agree at this stage. Although Hshieh teaches that non- orthogonal cells are preferable over square cells, Patent Owner has not pointed out anything in Hshieh that would “criticize, discredit, or otherwise discourage” modifying Kobayashi’s square cells to have rounded corners. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004); see also DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009) (“A reference does not teach away . . . if it merely expresses a general preference for an alternative invention . . . .”).
